This application claims the benefit of U.S. Provisional Patent Application No. 61/194,496, filed Sep. 26, 2008, entitled “Method for Efficient and Localized Production of Shoes.”
BACKGROUND OF THE INVENTIONShoe production is a labor-intensive process that has changed little despite advancements in automation over the past 100 years. Thus, most shoe manufacturing operations today require a significant amount of manual input. For example, one worker may cut, form, align, and stitch an upper piece of a shoe. While this process may utilize a number of machines, there is still a significant amount of human input required that can introduce variation between any two different uppers. This upper shoe piece may then be passed to another worker who may then add embroidery or other embellishments, which also require a significant amount of human input. These high levels of human input can introduce undesired variations in the finished shoe-product. Further, the large amount of human labor required in the making of shoes has limited the ability to produce on-demand custom shoes at a price deemed acceptable by most customers.
SUMMARY OF THE INVENTIONThis Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. The present invention offers several practical applications in the technical arts, not limited to methods for the production of specific types of shoes that are herein described.
The present invention relates to efficient shoe manufacturing methods and systems that reduce the specialized human labor required to manufacture a pair of shoes while avoiding the high costs and special maintenance requirements often associated with highly automated manufacturing equipment. Systems and methods in accordance with the present invention may be used to produce multiple models of custom shoes at a single shoe manufacturing facility. For example, one customer may order a particular model of shoe while a second customer may order a different model of shoe, yet both shoe models may be manufactured at the same facility by utilizing overlapping workflows.
The present invention is described in detail below with reference to the attached drawing figures, wherein:
The subject matter of the present invention is described with specificity herein to meet statutory requirements. However, the description itself is not intended to limit the scope of this patent. Rather, the inventors have contemplated that the claimed subject matter might also be embodied in other ways, to include different steps or combinations of steps similar to the ones described in this document, in conjunction with other present or future technologies. Moreover, although the term “step” may be used herein to connote different components of methods employed, the terms should not be interpreted as implying any particular order among or between various steps herein disclosed unless and except when the order of individual steps is explicitly described.
Embodiments of the invention may provide a method for efficiently producing shoes that may meet the demands of a geographic location. By way of example only and not limitation, a production facility for efficient production of shoes may be divided into particular modules, wherein a module may refer to an area of distributive labor or of specificity relating to one or more aspects of the shoemaking process, such as embroider or production of midsoles. In one embodiment, one or more modules may be designed to best benefit the working environment of individual operators such that the interaction between the operator and the machines in an operator's module are ergonomically designed to be conducive to the worker's good health. Each module may be referred to as a “module.” As a shoe component moves through modules, different processes and modifications may occur that comprise the steps in the overall manufacture of a shoe.
A shoe article, wherein a shoe article may be a final shoe or a partially final shoe or a component of a final shoe, may be produced only after a customer order has been received. A customer order may contain custom shoe parameters that pertain to one or more shoes produced for a given consumer. Moreover, since each shoe may be custom-made, each shoe may have a variety of characteristics according to each customer's request (e.g., a left-foot men's size 9 in blue with medium-level hardness may be paired with a right-foot men's size 9.5 with high-level hardness in red).
Once a customer has placed an order for one or more shoes, the order may be tracked throughout the production system so as to notify one or more operators of the unique characteristics of each order. In one method, the customer order may be presented to one or more operators on one or more sheets of paper. Each sheet of paper may travel to an appropriate operator so as to indicate to the operator what modifications to make to the shoe and/or shoe component the operator is modifying. The operator may then select the desired characteristics, such as a preferred color, from a source of materials within the modularized production facility, or the operator may select the desired design and/or markings from a series of program choices on a computer system. In the latter method, the operator may search through a pre-defined set of designs available for printing and/or embroidering and/or etching onto a material and may program the computer to print and/or embroider and/or etch the design onto a material. In another method, the operator may input a design or program supplied by the customer as a customized design on one or more shoe components.
In another embodiment, an operator can access information pertaining to a customer order throughout the shoe component-manufacturing facility by having the customer information stored on a database that is accessible to an operator in the shoe component-manufacturing facility. An operator may access the customer order information through a computer interface at or near one or more modules in the shoe-components manufacturing facility. An operator may also access information pertaining to the customer through the use of one or more bar codes. In one method, a bar code may access customer order info from a database that may contain all of the necessary information for the production of a customer's order of one or more shoes. A bar code may be used to access all information related to one or more shoe components, or may be used to access particular information related to one or more shoe components.
For example, an operator may scan one bar code at each software access point along the process. In another example, a bar code may be associated with each characteristic aspect and/or component of a shoe. For example, a bar code may be associated with the color which is desired to have on the background of a shoe component. In another example, a bar code may be associated with the components and/or designs desired to be reflected on an upper. In still another example, a bar code may be associated with to selection of components from a marketplace. For instance, one bar code may represent men's running shoes size 9, whereas another bar code may represent women's basketball shoes size 7. In another example, the use of bar codes may be associated with or supplanted by the use of number codes to supply the characteristics of a customer's order. For example, if a barcode is damaged or if a barcode reader is simply not working, an operator may input a number code to reflect the characteristic customer information associated with an order of one or more shoes.
There may be three starting points from which one or more shoe components are produced: the production of the outsole, the production of the midsole, and the production of the upper. The production of the outsole and/or midsole may begin before a customer places an order. An outsole and/or midsole may also be produced on an as-needed basis after a customer order is received for the production of one or more shoes.
Referring to the drawings in general, and initially to

With reference to the diagram of
In one embodiment, the first step in the production of the outsole may utilize injection rubber mold machine 102. Different-sized and/or -shaped molds may be used to produce a range of outsoles for a range of shoe sizes and styles. Various types and/or colors of rubber may also be used to produce outsoles with different functional and/or aesthetic properties. For example, indicating marks (such as dotted lines) may be used to guide a designer (e.g. someone who embroiders or adds mechanical lights or who uses glue or another form of adhesive to add fabric and accessories onto one or more shoe components) in the production of the outsole. In another case, different colors of shoe components may have a functional component, such as adding an easily seen color, such as bright yellow, to one or more shoe components to make a shoe-wearer more visible. Alternatively, different rubbers with a higher slippage may be placed along a shoe component in order to minimize the extent to which mud or other outside components stick to the shoe-wearer's one or more shoes.
The operator of injection rubber mold machine 102 may determine the number of each size, style, color, etc. of outsoles to make initially based on an indicator of outsoles required in outsole marketplace 118. For example, an indicator may include a pre-set range of expected sales for that store. A number of outsoles may also be created upon receipt of an indication of depleting inventory of a particular size, style, color, etc. The pre-set range of sales may be projected for a day or for another period of time, such as a week or a month or a season. The operator of injection rubber mold machine 102 alternatively or additionally may determine which size of outsole to make based on the quantity of outsoles of that size remaining in outsole marketplace 118. Outsole marketplace 118 of may comprise a plurality of temporary storage methods, with each temporary storage method corresponding to a particular style, size, color, functional property, etc. For example, a temporary storage method may comprise placing newly formed outsoles for size 9 in a first-come-first-serve (i.e. FIFO) queue. In another example, a temporary storage method may consist of an operator placing each newly formed outsole into a bin associated with one or more properties of that outsole (e.g., outsoles for men's size 9 are in one bin while outsoles for men's size 5 are in another bin). In still another example, a temporary storage method may comprise placing all newly formed outsoles into a bin and then allowing the operator to remove the appropriately sized outsole from the bin when needed, e.g. by choosing an outsole based on sight variation between different sized outsoles or by textured indications of different sized outsoles.
Upon determining that there is a low quantity of a certain size of outsole remaining in outsole marketplace 118, such as by visual inspection, the operator may then decide to manufacture outsoles of that size. Outsoles may also be produced in direct response to an order, and may be made having the style, size, color, functional properties, etc. specified in an order.
Once the outsole is removed by the operator from injection rubber mold machine 102 it may be placed into wash/dry area 114. Wash/dry area 114 may comprise one or more cleaning steps to clean the shoe and remove any residue from the rubber. For example, rubber residue may be caused by the oils and stearic acid used during a curing process. In another example, a curing process may eliminate the use of stearic acid in the curing process and/or reduce the amount of oil used in the curing process, thereby reducing or eliminating the need for wash/dry area 114. This curing process may reduce or eliminate the rubber residue produced during the curing process and may reduce or eliminate the need for one or more cleaning steps. As such, the outsole could be ready for priming directly after it is formed in injection rubber mold machine 116.
After washing, if any, the outsole may be dried. For example, the outsole may be dried using wash/dry area 114. In another example, the outsole may be dried by placing it in a sufficient heated, sufficiently de-humidified area (e.g. place the one or more shoes next to a window to dry). The operator may remove the dried outsole from wash/dry 114 and place it into outsole marketplace 118 to be available for use.
Outsole marketplace 118 and midsole marketplace 104 may be comprised of one or more temporary storage methods wherein midsoles may be stored in bins that are arranged according to size, style, color, or other attributes of the components stored in the bins. Outsole marketplace 118 and midsole marketplace 104 may store outsoles and midsoles that have been produced upon receipt of an indication of anticipation of customer orders. Outsole marketplace 118 and midsole marketplace 104 may also contain outsoles or midsoles produced upon receiving a specific customer order. By way of further example, outsoles and/or midsoles produced upon receipt of a customer order may bypass outsole marketplace 118 and/or midsole marketplace 104 and move directly onto further production steps. Still more embodiments may be obvious to one of ordinary skill in the art.
The production of the midsole may begin before a customer places an order. A midsole may also be produced on an as-needed basis upon the receipt of a customer order for one or more shoes. Further, a midsole may be produced as a result of the receipt of an indication that the quantity and character of midsoles remaining in midsole marketplace 104 should be adjusted.
To begin midsole production, a pre-measured volume of raw, unblown EVA pellets may be injected into a mold at injection mold pre-form 102 that is heated to approximately 100° Celsius. The temperature of the mold may be hot enough to melt the EVA pellets to conform to the shape of the mold, but not hot enough to activate the EVA's blowing agent. The product is an injection phylon biscuit, hereinafter referred to as a “biscuit,” that may be stored prior to activating the blowing agent to fabricate a midsole. Different volumes of EVA pellets may be associated with different shoe sizes, styles, densities and or hardnesses of portions of a midsole. Furthermore, the base polymer that is used in the injection phylon biscuit process may differ based on the ultimate hardness characteristic that is desired in the midsole of a shoe. Each set of shoes may contain one or more biscuits of varying volumes and dimensions comprising the midsole of each shoe. The hardness of one or more biscuits in a midsole may be customized to vary laterally and/or vary lengthwise across the shoe. Such a characteristic may, for example, prevent mild pronation in shoe users, such as runners, or simply enhance comfort.
Once the biscuit is made, it may be removed and placed into biscuit marketplace 108. From biscuit marketplace 108, the biscuits may be taken out on an as-needed basis. When a customer orders one or more shoes, for example, an operator may take one or more biscuits that are in accordance with the customer's order. In another method, operator may take the one or more biscuits from the marketplace and place them in a machine that exposes the one or more biscuits to a source of microwave radiation. For example, one or more biscuits may be placed in a Magic Chef MCB780W 1.2 kilowatt microwave and exposed to microwave radiation at high power for a period of sixty-five seconds.
Next, an operator may place each biscuit into press 106 which may be designated for left shoes and right shoes or a combination of both. The operator may load the left shoe designation or right shoe designation of press 106, and may use press 106 to configure each biscuit as “left” or “right.” The operator may then unload each biscuit from press 106. Press 106 may not be limited to holding only one biscuit, but may hold a plurality of biscuits at any given time. Moreover, the pressing of the biscuits need not be in sync with respect to each biscuit in press 106, but rather, may be designed to have multiple biscuits loading and pressing and unloading at any given time. In still a further example, an operator of a module may bypass the step of using a press 106 to designate a shoe article as being oriented “left” or “right”, and may simply use a lathe or a pair of shears or one or more blades to shape the biscuit by hand. An operator may also use another type of machine to designate each biscuit as being oriented “left” or “right” before placing each biscuit into a neutral, un-oriented press 106. An operator may also keep the biscuit as a neutral designation, such that each shoe part is interchangeable as being used for a left shoe and/or a right shoe.
Once press 106 contains the biscuit it may heat up to a temperature of approximately 172° Celsius that is sufficient to melt the biscuit. The temperature is sufficient to activate a blowing agent in the biscuit. This blowing agent may degrade the polymer chains and start a foaming process which increases the volume of the biscuit approximately 200% to conform to the shape of the press. Simultaneously, the a curing agent within the biscuit working at a slower reaction rate than the blowing agent may begin to cross-link polymer chains to hold the form of the augment biscuit.
After the augmented biscuit is formed, an operator may unload the augmented midsole from press 106 and load the augmented midsole into stabilization oven 110. Upon entering stabilization oven 110, the augmented midsole may be approximately 75° Celsius. In another example, the augmented midsole may enter stabilization oven 110 at a temperature that is higher or lower than 75° Celsius. In one example, the augmented midsole may be as hot as the highest temperature achieved in the press 106 and may be transferred at that same temperature into the stabilization oven 110. The stabilization process in stabilization oven 110 may be comprised of three or more cooling stages in which the temperature may decrease from approximately 75° Celsius to approximately 45° Celsius. In another example, the stabilization process in stabilization oven 110 may be conducted over a greater number of steps through the use of water and or air as mediums of cooling. In still another example, additional media and/or chemical solutions may be used to enhance the cooling process in the stabilization process of stabilization oven 110. The stabilizing process may decrease the volume of the augmented midsole by approximately 20% such that the midsole resulting from the stabilization process is approximately 160% of the original biscuit volume. In another example, the stabilizing process may be modified to increase or decrease the percentage change seen in the volume of the augmented midsole. In another method, any form of stabilization method may be used to stabilize one or more augmented biscuits, including immersion into water or other liquid at a desired temperature. In another example, augmented biscuits may be stabilized through the use of an aerosol solution or exposure to air at a desired temperature.
Another method of changing the volume of an augmented midsole may be to modify the midsole by hand, e.g. by the use of a lathe or the use of one or more cutting tools or the use of a second mold from which the augmented midsole may be placed in to decrease volume either by using pressure to shrink volume or using pressure to press a desired form from the augmented midsole and subsequently cutting and/or trimming off any undesired excess material.
Next, an operator may unload the biscuit from stabilization oven 110 and load the biscuit into wash/dry table 112 wherein a sonic bath may be used to clean one or more midsoles. Wash/dry table 112 may use one or more cleaning stages to clean a midsole. In another embodiment, the stabilization of the augmented biscuit may be combined with wash/dry table 112. In another embodiment, the biscuit may be unloaded from stabilization oven 110 and loaded into another type of cleaning machine and/or solvent and/or solution wash. In another example, each biscuit unloaded from stabilization oven 110 may be hand-polished by one or more operators.
Next, an operator unloads the biscuit from wash/dry table 112 and loads the biscuit into the drying oven. In another embodiment, the biscuit may be unloaded from wash/dry table 112 exposed to a sufficiently high temperature to evaporate a desired amount of water from the biscuit. The drying of the midsole may occur by placing the midsoles out to air dry. Next, an operator may unload the biscuit from drying oven and load the biscuit into marketplace.
At this point in the current embodiment, midsole marketplace 104 and outsole marketplace 118 may be comprised of a series of different classes of outsoles and the one or more midsoles described above. When a customer orders one or more shoes, the outsoles and the one or more midsoles associated with the customer's order may be removed from outsole marketplace 118 and midsole marketplace 104, respectively, if available. If one or more midsoles or outsoles of a customer's order are not available in midsole marketplace 104 or outsole marketplace 118, respectively, the necessary component or components may be made on a per-order basis.
After the outsole and one or more midsoles are removed from outsole marketplace 118 or midsole marketplace 104, respectively, they may be primed with an UV-activated primer at area 120. The primer may be placed on the one or more midsoles within 24 hours of its being activated. In an alternative embodiment, the primer can be placed on each outsole and midsole prior to entering outsole marketplace 118 or midsole marketplace 104, respectively.
After the outsole and the one or more midsoles are primed, each component may be placed in infrared oven 122. Once in the oven, the temperature may be increased to approximately 55° Celsius. At a sufficiently high temperature, the primer may be activated. Each component may then be removed from the infrared oven and an adhesive may be applied at prime and adhesive area 120. Each component may then be loaded into infrared oven 122, where it may be heated to approximately 55° Celsius, at which point the adhesive may be activated. Each component may then be removed from infrared oven 122. In an alternative embodiment, each component may have adhesive applied at prime and adhesive area 120 and then loaded into a standard oven to be heated. The standard oven may be heated, at which point the adhesive may be activated. The outsole and the one or more midsoles may be pressed together. For example, the outsole and the one or more midsoles may be hand-fit together through the use of bladder press 124 and standard press 126. In another example, the outsoles and midsoles may be loaded into a pressing alignment machine that works to fit the outsole and one or more midsoles together.
Once an outsole is pressed together with its associate midsole, the outsole-midsole is then placed in chiller 128. Chiller 128 may decrease the temperature of the outsole-midsole, to approximately 0° Celsius, allowing the adhesive to set. In an alternative method, the outsole-midsole may be set out to cool for a sufficient amount of time as is necessary to reduce the temperature of the adhesive to a point that it sets the adhesive. Next, the outsole-midsole may be sent to the staging area at swing arm post 130.
In one embodiment, the production of the upper may begin when the customer places an order for one or more shoes. After a customer places an order for one or more shoes, an operator may load a piece of synthetic material (e.g., synthetic leather, polyester, or mesh, etc.) onto eco-solvent printer 132. The synthetic material may be white, which may allow customer to request synthetic material to be printed with one or more desired aesthetic elements pertaining to the customer's order. Alternatively, the synthetic material may be dyed to customize the customer's order for one or more shoes. In another method, an operator may load a natural material (e.g. cotton or natural leather) onto eco-solvent printer 132. In another method, the desired color of a material may be loaded into eco-solvent printer 132. Loading a desired color of a material may reduce or eliminate steps for dyeing material.
The operator may then load eco-solvent printer 132 and dye sub printer 136 with materials associated with imprinting and/or dyeing and/or marking the parameters of customer's order onto eco-solvent printer 132. Eco-solvent printer 132 may then print to dye sub printer 136. Next, eco-solvent printer 132 may print. Next, eco-solvent printer 132 may cut out a customized synthetic from an original piece of synthetic material. In another method, the customized synthetic may be cut with the use of shears or a blade or the use of a press.
After the piece of customized synthetic has been cut, the operator may load a piece of customized synthetic into laser 140. The operator may then input the specifications given by the customer and may start the laser etching job, if applicable.
Next, the operator may remove the piece of customized synthetic and may load it into dye sub press 142. The dye sub press 142 may be used to imprint designs, such as a Nike swoosh, onto material. The operator may remove the laser cut upper from the dye sub press 142 and load the upper into embroidery machine 146. The operator may then start embroidering machine 146, customizing the upper by embroidering a desired set of designs using a desired set of colors. The operator can then unload the customized upper from embroidering machine 146 and deliver it to radio frequency welder 148.
At this point in the process, the upper and outsole-midsole may be retrieved by an operator. The operator may also retrieve a kit of the remaining shoe components from marketplace 150. In one embodiment, the remaining shoe components are composed in a “kit” wherein an operator can, for example, retrieve the remaining components needed for a Men's size 9 running shoe. In another method, one or more operators may retrieve one or more remaining shoe components from a marketplace of kit components. After the shoe components are gathered, the operator may utilize radio frequency welder 148 to combine the components.
After the parts of the upper have been assembled, the operator may make one or more final cuts with final trim clicker 144 to define the shape of an upper. In another example, the upper may be cut by an operator using visual judgment and or expertise to guide the operator in knowing where and/or at which angle and/or how much to cut. Swing arm 130 may then stitch the upper to the outsole-midsole. In another example, the upper may be stitched by an operator using visual judgment and or expertise to guide the operator in knowing where and/or at which angle and/or how much to cut. This sub-assembly may then be sent to lasting area 152.
In
Again, it should be understood that this and other arrangements and workflows described herein are set forth only as examples. Other arrangements and elements (e.g., processes, methods, etc.) can be used in addition to or instead of those shown and discussed, and some elements may be omitted altogether.
In step 205, shoe model options may be presented to a customer. Shoe model options presented in step 205 may include, for example, a running shoe model, a basketball shoe model, and a skate shoe model. Of course, other shoe models, both athletic and non-athletic may be alternatively or additionally comprise available shoe model options presented in step 205. Step 205 may optionally comprise, for example, all available shoe model options that are available to be made on-site at a connected or local shoe manufacturing facility. Additionally, shoe model options may comprise shoe models capable of being made on-site at a connected or local shoe manufacturing facility along with shoe models not capable of being made on-site at a connected or local shoe manufacturing facility. An indication of whether a particular shoe model may optionally be made on-site at a connected or local manufacturing facility or not may also be optionally presented. Step 205 may comprise, for example, presenting information describing the available shoe model options, along with an indication of local manufacturing availability for each particular model, to a customer on a computer using a graphical user interface.
In step 210, a customer's shoe model selection may be received. For example, step 210 may comprise receiving a user selection of a presented shoe model from within a graphical user interface. A customer may select a checkbox associated with a basketball shoe model, for instance, to indicate that he or she would like to order a basketball shoe.
In step 215, functional options for the selected shoe model may be presented to the customer. Similarly to step 205, step 215 may be performed, for example, within a graphical user interface operating on a computer. Functional options may include parameters such as shoe size. Other types of options that may be selected in step 215 may include outsole hardness options, support options, motion control options, outsole texture options, outsole material options, and the like. It should be appreciated that step 215 need not necessarily be presented after step 205 and step 210, but that in many instances the functional options available may depend upon the shoe model selected. For instance, functional options relating to foot motion control may be relevant to a running shoe and therefore made available for customer selection after a customer has selected a running shoe model, while motion control options are not relevant for a basketball shoe, and therefore need not be available for basketball shoe models. Additionally, similarly to step 205, site-manufacturing information specific to each functional option may be indicated. For example, some functional options may be available for shoes manufactured on-site at a connected or local manufacturing facility, while others may only be available at a non-local manufacturing facility. One or ordinary skill in the art will readily appreciate any number of other types of functional options that are relatively specific to one or more particular model type of shoe.
In step 220, a customer's functional options selection may be received. Similarly to step 210, step 220 may be performed, for example, within a graphical user interface operating on a computer. For example, step 220 may comprise receiving a user selection of a specific functional option, such as midsole hardness, within a graphical user interface. For example, a customer may select a checkbox associated with an indication of midsole hardness to indicate that he or she would like the midsoles on his or her shoes to be of a specific hardness.
In step 225, aesthetic options for the selected shoe model and/or functional options may be presented to the customer. Step 225 may occur using a graphical user interface on a computer, similarly to step 205 and step 215. The aesthetic options presented in step 225 may depend, at least in part, upon the model option selected by a customer and/or the functional options selected by a customer. However, it is also possible that aesthetic options may exist entirely or partially independent of model and/or functional options, in which case step 225 may occur prior to or in conjunction with step 205 and/or step 215. For example, options regarding shoe color may not depend upon shoe model or functional options. On the other hand, options relating to the color of a particular functional element, for example, will necessarily be dependent upon whether that functional element has been selected, either as part of a shoe model selection or as a functional option. Also, similarly to step 205, site-manufacturing information specific to each aesthetic option may be indicated. For example, some aesthetic options may be available for shoes manufactured on-site at a connected or local manufacturing facility, while others may only be available at a non-local manufacturing facility.
In step 230, the aesthetic option selections may be received from the customer. Step 230 may be performed, for example, by receiving customer selections using a pointing device in a graphical user interface on a computer, for example, by clicking checkboxes appropriate for each aesthetic option selected.
In step 235, a customer's site manufacturing options may be presented.
Similarly to step 205, step 235 may be performed, for example, within a graphical user interface operating on a computer. Site manufacturing options presented in step 235 may comprise, for instance, an option for on-site manufacture at a connected or local manufacturing facility, the option for manufacture at a specific local or non-local facility, or an option to indicate no site-manufacturing preference. It may be appreciated that the options presented in this step may be influenced by the customer's selection of shoe model in step 210, the customer's selection of functional shoe options in step 220, and/or the customer's selection of aesthetic options in step 230. For example, if a customer selects a shoe model in step 210 that cannot be manufactured on-site at a connected or local manufacturing facility, step 215 might not present such a manufacturing option to the user. Also, as an example, if a customer selects a functional option in step 220 or and aesthetic option in step 230 that cannot be incorporated into a shoe at a specific manufacturing site, such manufacturing site might not be included in the list of manufacturing options in step 235. Step 235 may comprise, for example, presenting to the user a list of options comprising all sites where a particular model of shoe with the particular selected functional and aesthetic options may be manufactured.
In step 240, a customer's site manufacturing selection may be received. Similarly to step 210, step 240 may be performed, for example, within a graphical user interface operating on a computer. For example, step 240 may comprise receiving a user selection of a presented manufacturing facility from within a graphical user interface. For example, a customer may select a checkbox associated with an local manufacturing facility to indicate that he or she would like his or her shoes to be manufactured on-site at a connected or local manufacturing facility.
In step 245, pickup options for the selected shoe model may be presented to the customer. For example, step 245 may comprise presenting a list of options to the user comprising the option of picking up the shoes at the store where an order has been placed, the option of picking up the shoes from a connected or local manufacturing facility, the option of having the shoes delivered to a different store location, and the option of having the shoes delivered to the customer at his or her residence. It will be appreciated by one of ordinary skill in the art that the options presented in this step may be tailored to reflect the customer's manufacturing site selection in step 240. For example, if in step 240 a user selects on-site manufacturing for his or her order, step 245 may present the user with the option of picking his or her shoes up from the store or from a connected or nearby manufacturing facility. On the other hand, if, for example, the customer in step 240 selects a shoe that cannot be manufactured on-site, the options presented in step 245 might not comprise the option to pick up the shoes at a nearby manufacturing facility.
In step 250, a customer's pickup selection may be received. Similarly to step 210, step 250 may be performed, for example, within a graphical user interface operating on a computer. Step 250 may comprise, for instance, receiving a user selection of a pickup option from within a graphical user interface. For example, a customer may select from a dropdown list to indicate that he or she would like his or her shoes to be available for pickup at the store in which the order was placed. Alternatively, step 250 may comprise receiving an indication that the user would prefer to have his or her order mailed to his or her residence. In another example, step 250 may comprise receiving an indication that the user would prefer to have his or her order delivered to another store site for pickup.
In step 255, a workflow may be initiated in a facility designated by the user in step 240 to construct an outsole in accordance with the shoe model option selected by the customer. The workflow may also incorporate the functional options, and/or aesthetic options selected by a customer. For example, if, in step 210, the customer selected a basketball shoe model, a basketball shoe workflow may be initiated in the outsole manufacturing compartment. It should be noted that the specific basketball shoe workflow for any particular basketball shoe may vary to some degree such that the customer's particular functional and/or aesthetic selections be incorporated into the final basketball shoe yet the workflow may still be considered a basketball shoe workflow (as opposed to being a skate shoe workflow). Alternatively, had the customer selected a running shoe model in step 210, for instance, a running shoe workflow may be initiated to construct an outsole in accordance with a running shoe model.
It should first be noted that step 255 need not necessarily incorporate a different workflow for each shoe model, as some shoe models may exhibit a certain amount of overlap in certain component manufacturing compartments. For example, a workflow for a skate shoe outsole may be similar enough to a workflow for a basketball shoe outsole such that there need be only one outsole workflow for the production of both basketball and skate shoe outsoles. This does not necessarily mean, however, that each component for these shoes can similarly share a workflow; while the workflow for a basketball shoe outsole may converge with the workflow for a skate shoe outsole such that a single outsole workflow common to both shoe models may be utilized, for instance, the workflows for each shoe may diverge significantly in the production of their respective midsoles such that separate midsole workflows need be maintained. Different shoe model workflows may thus be implemented in various component manufacturing compartments with varying degrees of overlap. These overlapping, diverging and converging workflows allow for the efficient manufacture of multiple models of shoes in a single manufacturing facility while at the same time reducing physical footprint of said manufacturing facility.
It should finally be noted that step 255 need not be necessarily initiated by a specific selection by a specific customer. For example, a predetermined level of inventory of outsoles having various characteristics may be maintained. Outsoles in three different colors may be made in each available size for each of three different models of shoes available at a facility, for instance. Outsoles may then be used from the inventory based upon customer orders. Whenever a given model, size, and color of outsole begins to run low in inventory, an operator may then initiate a workflow for that model to construct additional outsoles meeting those parameters. In this way, step 255 may be performed in a way that is responsive to the shoe model, functional options, and/or aesthetic options selected by customers, while not being directly initiated by those customer selections. Further, step 255 may be performed in different ways for different types of outsoles, for example by using an inventory system to initiate workflows for commonly used outsoles and initiating workflows that produce less commonly used outsoles only in response to orders requiring them.
In step 260, a workflow for the production of a midsole may be initiated in accordance with the shoe model; functional and/or aesthetic options may also be incorporated in accordance with the customer's selected options. First, it should be noted that, similarly to step 255, each shoe model may not necessarily have its own specific workflow but rather may share a workflow with another shoe model. Second, similarly to step 255, a workflow for a particular shoe model may vary to some degree to allow for the functional and/or aesthetic customizations selected by the user to be incorporated into the shoe model. Third, also similarly to step 255, step 260 need not be initiated in response to any given shoe order by a particular customer, but may instead optionally utilize an inventory system to initiate workflows to produce midsoles having the desired characteristics. Finally, similarly to step 255, initiating workflows to produce midsoles may be performed in different ways for different types of midsoles, for example by using an inventory system to initiate workflows for commonly used midsoles and initiating workflows to produce less commonly used midsoles only in response to orders requiring them.
In step 265, a workflow may be initiated to ready the outsole and midsole to be affixed together in accordance with the selected shoe model; functional options and aesthetic options desired by the customer may also be incorporated. Step 265 may comprise, for example, removing from outsole marketplace one or more outsoles appropriate to the customer's order, removing from midsole marketplace one or more midsoles appropriate to customers order, skiving the edges of the removed midsole(s) and outsole(s), placing the removed midsole(s) and outsole(s) in infrared oven, priming the removed midsole(s) and outsole(s), and again placing the removed midsole(s) and outsole(s) in infrared oven. It should be noted that similarly to steps 255 and 260, each shoe model may not necessarily have its own specific workflow at step 265 but rather may share workflows with other shoe models. Also similarly to step 255 and 260, a workflow for a particular shoe model may vary to some degree to allow for the functional and/or aesthetic customizations selected by the user to be incorporated into the shoe model.
It should also be noted that any and/or all workflows for any and/or all compartments, including those utilized in steps 255 and 260, may advantageously take similar amounts of time to complete, allowing for completed components to be complete at similar times. For example, the workflows from steps 255 and 260 may produce components that arrive at similar times so that they may be readied in step 265 without the need to delay initiating a workflow in step 265 to wait for certain necessary components to arrive.
As an example, if a customer selected a basketball shoe model, step 255 may comprise initiating a basketball shoe workflow that comprises the steps of (1) injection molding a rubber outsole taking approximately 220 seconds of machine time and approximately 15 seconds of human time, (2) removing flash and staging the outsole in a finished outsole marketplace taking approximately 5 seconds of human time, (3) removing the outsole from the finished marketplace taking approximately 5 seconds of human time, (4) alkaline washing the outsole taking approximately 50 seconds of machine time, (5) acid washing the outsole taking approximately 50 seconds of machine time, (6) drying the outsole taking approximately 90 seconds of machine time, (7) removing the outsole from the drying oven taking approximately 2 seconds of human time, and (8) staging the outsole in the outsole marketplace taking approximately 3 seconds of human time. Thus, the workflow for producing a basketball shoe outsole in this example may take approximately 350 seconds.
This being the case in this example, it may be advantageous for the workflow utilized in step 260 to similarly take approximately 350 seconds so that the parts may arrive at similar times so that step 265 may proceed without undue delay.
It should further be noted that any workflow may overlap not only spatially but also temporally with another workflow. For example, a workflow for the production of a basketball midsole in step 260 may comprise (1) injection molding a biscuit taking approximately 30 seconds of machine time, (2) placing the biscuit in biscuit marketplace taking approximately 10 seconds of human time, (3) heat pressing the biscuit taking approximately 420 seconds of machine time and approximately 20 seconds of human time, (4) loading the biscuit into a stabilization oven taking approximately 5 seconds of human time, (5) heating the biscuit to produce a midsole taking approximately 3600 seconds of machine time, (6) removing the biscuit from the stabilization oven taking approximately 5 seconds of human time, (7) water washing the midsole taking approximately 600 seconds of machine time, (8) drying the midsole and staging it in midsole staging marketplace taking approximately 300 seconds of machine time and approximately 5 seconds of human time, (9) removing the midsole from midsole staging marketplace taking approximately 2 seconds of human time, and (10) staging the midsole for assembly taking approximately 3 seconds of human time.
Utilizing this example workflow without temporal overlap would thus produce a midsole approximately every 5000 seconds. However, while step (5) for instance may in this example take approximately 3600 seconds, the stabilization may be done by a load stabilization oven that may comprise a unit that allows multiple midsoles to be in the process of stabilization at once. So, for instance, a first basketball midsole workflow may be initiated, and steps (1), (2), (3) and (4) may be performed on a first biscuit. In step (5), the first biscuit may need to remain in the stabilization oven for approximately 3600 seconds to become a first midsole. During this time, while this first biscuit is thus in the stabilization oven, a second midsole workflow, basketball or otherwise, may be initiated, starting with step (1) for that particular workflow, and progressing up to the step in that particular workflow wherein the second biscuit is loaded into the stabilization oven, for example. At this point in the example, two separate workflows are in progress, each having progressed up to and being currently in the stabilization step; accordingly, two or more different biscuits, associated with different models of shoe or not, may be in the stabilization oven in different stages of stabilization at any given time. Any number of workflows may thus be initiated be in varying stages of progress and overlap in such a manner. At the point in time when the stabilization of step (5) for the first workflow is finished, the first midsole may be removed from the stabilization oven and the first initiated basketball midsole workflow may be resumed at step (6).
In another example of temporally overlapping workflows, and again referring to the example basketball midsole workflow above, after having loaded the first biscuit into the stabilization oven at step (5), a second workflow may be initiated to produce a basketball shoe outsole. This second workflow may be completed and a third basketball outsole workflow may be initiated and completed. As would be appreciated by one of ordinary skill in the art, any number of workflows may be thus initiated while the first midsole workflow from the above example remains in step (5). At any point in time, the midsole workflow of the original example may be resumed at step (6) to complete the first midsole.
It may be noted that these workflows may overlap in any advantageous manner as would be obvious to one of ordinary skill in the art. In this example, each workflow may be tailored to overlap such that a new midsole will emerge in an amount of time similar to the amount of time it takes to produce other shoe components in this or other shoe component manufacturing compartments. This may advantageously allow various components to arrive at similar times to undergo a joining workflow for instance. In the current example, for instance, through the use of temporally overlapping workflows, a midsole may be produced approximately every 350 seconds to coincide with the amount of time it takes to execute an outsole workflow from the example used in step 255. These two workflows may thus take a similar amount of time to produce two components to be joined utilizing a joining workflow without undue delay. It should also be noted that the use of temporally overlapping workflows can be applied to any step utilizing workflows, such as, for example, steps 255 and 260, as would be obvious to one of ordinary skill in the art.
In step 270, one or more customization workflows for an upper for a particular shoe model may be initiated in accordance with the shoe model; again, functional options, and/or aesthetic options selected by a customer may be incorporated. It should again be noted that, similarly to step 255, 260, and 265, each shoe model may not necessarily have its own specific workflow but rather may share a workflow with another shoe model. Also similarly to step 255, 260, and 265, a workflow for a particular shoe model may vary to some degree to allow for the functional and/or aesthetic customizations selected by the user to be incorporated into the shoe model. While step 270, similarly to step 255, 260, and 265, may be performed without regard to any particular order by a customer, in practice the customization attainable in a shoe upper will likely result in step 270 being performed in response to a specific customer order. For example, step 270 may initiate a workflow to construct an upper for a running shoe having a red color. Similarly, step 270 may initiate a workflow to construct uppers for other types of shoe models, such as basketball shoes or skate shoes; these workflows may further incorporate any of a variety of functional characteristics, such as additional ankle support, side ventilation, and other similar functional options, with any of a variety of aesthetic options, such as particular colors, stitching patterns, insignia, and the like.
As another example, step 270 may comprise initiating a basketball shoe upper customization workflow comprising (1) printing echo-solvent customization taking approximately 120 seconds of machine time and approximately 30 seconds of human time, (2) cutting vamp liner and vamp qtr. taking approximately 30 seconds of human time, (3) laser customization taking approximately 120 seconds of machine time and approximately 30 seconds of human time, (4) embroidery customization taking approximately 120 seconds of machine time and approximately 30 seconds of human time, (5) delivering parts to heat press taking approximately 5 seconds of human time, and (6) checking the marketplace and cutting the parts if needed, taking approximately 6 seconds of human time. Thus, the basketball workflow in this example may take approximately 491 seconds. It should be noted that this process may, similarly to steps 255, 260, and 265, use varying degrees of temporally overlapping workflows such that an upper may be produced in a shorter amount of time more similar to the amount of time it takes to produce other components in this or other compartments utilizing different workflows. For example, temporally overlapping workflows may be utilized such that a customized upper, of any model type, may be produced approximately every 350 seconds.
As another example, and to further illustrate how workflows may overlap spatially, step 270 may comprise initiating a running shoe upper customization workflow in response to having received certain customer model selection input. This workflow might comprise, for example, (1) printing echo-solvent customization taking approximately 120 machine seconds and approximately 30 human seconds, (2) cutting vamp liner and vamp qtr. taking approximately 30 human seconds, (3) print dye sublimation customization taking approximately 120 machine seconds and approximately 20 human seconds, (4) press dye sub.
customization taking approximately 12 machine seconds and approximately 10 human seconds, (5) laser customization taking approximately 120 machine seconds and approximately 30 human seconds, (6) embroidery customization taking approximately 120 machine seconds and approximately 30 human seconds, (7) delivering customized parts to radiofrequency welding marketplace taking approximately 5 human seconds, and (8) checking radiofrequency welding marketplace and cutting parts if needed, taking approximately 6 human seconds. Thus, in this example, a customized running shoe upper may be constructed in approximately 613 seconds. It should be noted that this process may, similarly to previous steps utilizing workflows, use varying degrees of temporally overlapping workflows such that a running upper may be produced in a shorter amount of time more similar to the amount of time it takes to produce other components in this or other compartments utilizing different workflows. For example, temporally overlapping workflows may be utilized such that a customized running upper, of any model type, may be produced approximately every 350 seconds. It should be noted also that it will be obvious to one of ordinary skill in the art how, in these examples, this running shoe upper customization workflow overlaps similar machines, skills, and work areas involved in the basketball shoe upper customization workflow given as an example above.
In step 275, one or more workflows for further manufacturing an upper for a particular shoe model may be initiated in accordance with the shoe model; again, functional options, and/or aesthetic options selected by a customer may be incorporated. It should again be noted that, similarly to step 255, 260, 265, and 270 each shoe model may not necessarily have its own specific workflow but rather may share a workflow with another shoe model. Also similarly to step 255, 260, 265, and 270, a workflow for a particular shoe model may vary to some degree to allow for the functional and/or aesthetic customizations selected by the user to be incorporated into the shoe model. While step 275, similarly to step 255, 260, 265, and 270, may be performed without regard to any particular order by a customer, in practice the customization attainable in a shoe upper will likely result in step 275 being performed in response to a specific customer order, or, more specifically, to the upper piece produced in step 270. For example, step 275 may initiate a workflow to stitch an upper for a running shoe according to the user selections, said upper having been produced and customized according the user selections in step 270.
As an example, step 275 may comprise initiating a basketball upper forming and stitching workflow comprising (1) gathering parts from marketplace taking approximately 15 seconds of human time, (2) assembling the upper pieces taking approximately 20 seconds of machine time and approximately 30 seconds of human time, (3) activating heat press taking approximately 10 seconds of machine time and approximately 2 seconds of human time, (4) loading the parts into cooling rack taking approximately 60 seconds of machine time and approximately 1 second of human time, (5) cutting final trim taking approximately 15 seconds of human time, (6) heel forming taking approximately 180 seconds of machine time and approximately 20 seconds of human time, (7) post stitching taking approximately 30 seconds of human time, (8) strobel stitching taking approximately 40 seconds of human time, and (9) delivering the upper to lasting station taking approximately 5 seconds of human time. Thus, the basketball upper forming and stitching workflow in this example may take approximately 428 seconds. It should be noted that the process in the above example may, similarly to steps 255, 260, 265, and 270, use varying degrees of temporally overlapping workflows such that an upper may be produced in a shorter amount of time more similar to the amount of time it takes to produce other components in other compartments utilizing different workflows. For example, in step (6), while waiting for a machine to stitch the heel, the operator may initiate another workflow for the same or another model of shoe. When the operator reaches step (6) in this second workflow, for instance, the first upper may be finished with step (6) and the operator may then perform step (6) on the second upper and, while allowing the machine to continue with step (6) on the second upper, may continue with steps (7), (8), and (9) on the first upper. Any of these or steps any other steps of a given workflow may be advantageously overlapped as would be obvious to one of ordinary skill in the art.
As another example, and to further illustrate how workflows may overlap spatially, step 275 may comprise initiating a running shoe upper radiofrequency welding and stitching workflow. This workflow might comprise, for example, (1) gathering parts from radiofrequency welding marketplace taking approximately 15 seconds of human time, (2) assembling upper pieces taking approximately 30 seconds of human time, (3) activating the radiofrequency welding cycle taking approximately 10 seconds of machine time and approximately 10 seconds of human time, (4) cutting final trim taking approximately 15 seconds of human time, (5) stitching upper to sole taking approximately 60 seconds of human time, and (6) delivering to final quality control area taking approximately 5 seconds of human time. This example workflow may thus take approximately 145 seconds. It should be noted that this process may, similarly to previous steps utilizing workflows, use varying degrees of temporally overlapping workflows such that a running shoe upper may be produced in a shorter amount of time more similar to the amount of time it takes to produce other components in this or other compartments utilizing different workflows. For example, temporally overlapping workflows may be utilized such that a customized running upper, of any model type, may be produced approximately every 350 seconds. It should be noted also that it will be obvious to one of ordinary skill in the art how, in these examples, this running shoe upper radiofrequency welding and stitching workflow overlaps similar machines, skills, and work areas involved in the basketball upper forming and stitching workflow given as an example above.
In step 280, a workflow may be initiated such that the outsole, midsole, and upper may be affixed together to form the selected shoe model in accordance with the selected shoe model; functional options and aesthetic options desired by the customer may also be incorporated. Step 280 may comprise, for example, matching the appropriate outsole, the appropriate midsole, and a specially customized upper to form a single shoe as ordered by a customer. It should be noted that similarly to steps 255, 260, 265, 270, and 275, each shoe model may not necessarily have its own specific workflow at step 280 but rather may share workflows with other shoe models. Also similarly to step 255, 260, 265, 270, and 275, a workflow for a particular shoe model may vary to some degree to allow for the functional and/or aesthetic customizations selected by the user to be incorporated into the shoe model.
In another example, step 280 may comprise (1) applying adhesive to the upper produced by step 275, the midsole produced by step 260, and the outsole produced by step 255 taking approximately 75 human seconds, (2) placing the parts in oven taking approximately 120 machine seconds, (3) hand fitting the parts together taking approximately 75 human seconds, (4) pressing the parts taking approximately 30 machine seconds and approximately 10 human seconds, (5) chilling the parts taking approximately 60 machine seconds and approximately 5 human seconds. Thus, the workflow in this example may take approximately 460 seconds. It should be noted that, like the other steps utilizing workflows in this example, and number of workflows may be temporally overlapped to lower the amount of time it takes to complete step 280 as would be appreciated by one of ordinary skill in the art.
In step 285, a workflow may be initiated to quality control, lace and last the customized combined shoe component; functional options and aesthetic options desired by the customer may also be incorporated. It should be noted that similarly to steps 255, 260, 265, 270, 275, and 280, each shoe model may not necessarily have its own specific workflow at step 280 but rather may share workflows with other shoe models. Also similarly to step 255, 260, 265, 270, 275, and 280, a workflow for a particular shoe model may vary to some degree to allow for the functional and/or aesthetic customizations selected by the user to be incorporated into the shoe model.
In an example, step 285 may comprise (1) quality control checking and lasting the combined shoe component taking approximately 90 seconds of machine time and approximately 90 seconds of human time, (2) quality control checking and de-lasting the combined shoe component taking approximately 30 seconds of human time, (3) lacing the combined shoe component taking approximately 60 seconds of human time, and (4) packing the shoe taking essentially no time. Thus, the workflow in this example may take approximately 270 seconds. It should be noted that, like the other steps utilizing workflows in this example, and number of workflows may be temporally overlapped to change the amount of time it takes to complete step 285 as would be appreciated by one of ordinary skill in the art.
In step 290, the customized shoe may be delivered to a customer in accordance with the customer's selected pickup options from step 245. Step 290 may further include inspection and approval by a customer, payment, etc. It should be appreciated that while step 290 may occur geographically distant from the location at which all or parts of the other steps of method 200 are performed, one desirable attribute of method 200 is that it permits the localized manufacture of shoes to custom orders. Such localized manufacturing can be more responsive to local needs and preferences than remote manufacturing, and can provide reduced inventory and shipping costs. Accordingly, step 290 may occur geographically near, in fact in the same larger facility, as does the remainder of steps of method 200.
Turning now to
At step 315, flash is removed from the outsole. One method of removing flash from the outsole includes cutting and/or removing and/or trimming undesired excess rubber. Another method of removing flash may be to hand-wipe or hand-pick the flash off the rubber outsole. At a step 320, the outsole is staged in an outsole pre-wash marketplace. In one alternative, the number and character (e.g., size, shape, color, etc.) of outsoles placed into a marketplace are based on an expectation of demand. At a step 325, an order is received. An illustrative method for receiving an order includes receiving an order manually. In still another method, an order may be received by uploading details of an order through a web interface. In one alternative, steps 305-320 are not performed until after an order is received. In that alternative, the outsole is produced on an as-needed basis, not as a result of a projected market demand. At step 330, the outsole is removed from the outsole pre-wash marketplace.
At step 335 the outsole is washed. In one method, the outsole is washed by way of an alkaline solution. In another method, the outsole may go directly from step 315, where the flash is removed from the outsole, to step 335, where the outsole is washed. At step 340 the outsole is washed. In one method the outsole is washed by way of an acid solution. The washing steps 335 and/or 340 may be a means of removing excess rubber residue created by the curing process at step 310. In another method, a curing process may be used wherein stearic acid is not used, thereby reducing or minimizing the rubber residue produced. In this method, the cleaning steps 335 and/or 340 would be reduced in time and/or materials, or could be eliminated. At step 345 the outsole is dried in an oven. In another way, an outsole may be dried in any way that is capable of producing heat that dries the outsole to a desired dryness within a desired period of time. At step 350 the outsole is removed from the oven. In another method, the outsole may be removed from another heating device that has been used to take away moisture from the outsole mold. At step 355, the outsole is staged in an outsole staging marketplace. In another method, where there is little or no rubber excess produced from the curing process 315, the outsole may go directly from the curing process 315 to being staged in the outsole staging marketplace 355. In another method, where there is minimal rubber residue, the outsole may go from the curing process 315 to a cleaning step 335 wherein the outsole is wiped with a material, such as a cloth, to remove the excess rubber. In the former example, the outsole may either go directly from the curing process 315 to a cleaning step 335, or may go from the curing process 315 to an outsole marketplace 320 before being removed from an outsole marketplace 330. The outsole would be able to skip the time spent in an outsole marketplace 320-330 when an order is received prior to the production of the outsole (e.g. when the outsole is produced on an as-needed basis).
Referring to
At step 420, the biscuit is removed from the biscuit marketplace. At step 430, biscuit is then loaded into a heat press. In another method, such as when an order is received prior to the biscuit being made, the biscuit may go directly from being removed from an injection mold 406 to being loaded into a heat press 430. In another method, there is a right heat press and a left heat press for the right-shoe-biscuit and left-shoe-biscuit, respectively. In still another method, the right heat press and the left heat press may be operated concurrently. At step 434, the biscuit is then heated to 172° Celsius. In another embodiment, the biscuit may be heated to a temperature that may be hot enough to activate the foaming agent. At step 438, the biscuit is removed from the heat press. In step 440, the biscuit is loaded into a stabilization oven. In the stabilization oven, the biscuit is cooled to a lower temperature that allows the biscuit to become the desired size as a midsole. At step 444, the biscuit may be placed into an air stabilization oven and the temperature may be lowered to 75° Celsius. The process by which air is passed over a biscuit in a stabilization oven may be through the use of one or more air knife centrifugal blowers. In steps 448-452, the biscuit may have its temperature lowered over three stages. At step 448, the temperature of the biscuit may be lowered from 75° Celsius to 65° Celsius. At step 452, the temperature of the biscuit may be lowered from 65° Celsius to 55° Celsius. At step 454, the temperature of the biscuit may be lowered from 55° Celsius to 45° Celsius. In another method, the cooling stages of 448-452 may be done in three or more stages. In another alternative method, the step at 444 of lowering biscuit temperature to 75° Celsius may be adjusted to a higher or lower temperature. In another method, one or more biscuits may be stabilized using a series of baths of water that may range from 90° Celsius to 45° Celsius. The temperature of the biscuit may decrease from 90° Celsius to 75° Celsius, then 75° Celsius to 45° Celsius, wherein the time within each bath may be spread evenly.

Cutting and kitting module 2402 may cut shoe upper components from an inventory of raw upper materials. At least one of the raw upper components may comprise a customizable gray good. The cut shoe upper materials may then be assembled into kits. In embodiments, the kits comprise all of the upper elements necessary to form an entire shoe upper. The kits may then be temporarily stored.
Initially, cutting and kitting module 2402 may cut out the components required for the fabrication of a shoe upper and prepare those assorted pieces into a kit that may be used in the construction and customization of a shoe. Materials used in the cutting and kitting module 2402 may be stored in a material storage 2413. The raw materials used to create the shoe components may be supplied by vendors that may or may not apply a hot melt lamination across to the raw materials. The lamination treatment may aid in the construction of the shoe components, as the lamination may be used to adhere the shoe components. As such, if materials for the shoe components do not yet have a hot melt lamination as supplied from the vendors, a hot melt lamination may be applied to the raw material. In embodiments, raw materials retrieved from storage 2413 may have a hot melt lamination applied to the materials at hot melt lamination press 2412. However, if materials supplied from vendors already have a hot melt lamination applied, hot melt lamination press 2412 may not be needed in diagram 2400.
After materials have been retrieved from material storage 2413, a component cutting machine 2414 may be used to modify the materials into shoe components. Component cutting machine 2414 may comprise an auto-cutting machine that may utilize blades, lasers, and/or any other cutting methodology or tool to cut the fabrics used to construct a shoe upper into one or more pieces for fabrication. Fabric may be held in place using suction, clamps, etc. when used by an auto-cutting machine such as one that may be used by component cutting machine 2414. The material used in the fabrication of a shoe upper may comprise gray goods that may be readily customized through printing, dying, embroidering, etc. Cut components may be stored in a component marketplace 2416. Once cut components are stored in the marketplace, the cut components may be assembled into kits. In embodiments, kits may comprise the upper components required to assemble an upper for a single shoe or the uppers for a pair of shoes. In embodiments, storage 2413 and marketplace 2416 may comprise a vertical carousal. Depending upon the shoe designs fabricated, a single kit of upper components may be utilized to assemble a shoe of a single size or a shoe of any of a plurality of sizes. For example, for some shoe designs, a single kit might be able to be used to fabricate and assemble a shoe having men's size 8, 9, or 10.
Upper kits may be provided from cut components stored in marketplace 2416 on an as-needed basis as shoe orders are processed. Cutting and kitting module 2402 may thereafter respond to shortages for particular components of marketplace 2416 by cutting and kitting the needed types of upper materials.
After a kit has been selected from component marketplace 2416, the kit may be customized in customization module 2404. In alternative embodiments, customization module 2404 may retrieve temporarily stored kits from cutting and kitting module 2402. Customization module 2404 may then layer the shoe upper components of the kit into a flat framed assembly with multiple layers. Customization module 2404 may then customize at least a portion of the shoe upper components by applying decoration to the shoe upper components.
In embodiments, customization module 2404 may comprise a plurality of discrete stations, but no single shoe upper need necessarily be processed by every station in customization module 2404. For example, after a kit has been delivered to desk 2418, a operator, such as operator 2401, may load up any print files related to a customization order.
Print files may be related to order customization as input by a customer at a customer input receiver 2422. In embodiments, print files may be sent to an eco-solvent printer 2420 and/or a digital printer dye sublimation stations. In embodiments, eco-solvent printer 2420 may be used to print graphics for application to a shoe upper from the kit. Further, digital printing dye sublimation station 2422 may be used to sublimate designs and/or graphics onto a shoe upper.
The upper customization may also utilize a lamination heat press 2424 to laminate designs onto shoe upper components. Similarly, dye sublimation patterns printed at 2422 may be applied using dye sublimation heat press 2426. Additionally, customization trim work may be performed at station 2428, where station 2428 may comprise a first trim clicker. In embodiments, a first trim clicker may be used to modify material used in upper customization. Further, laser customization, such as customized cutting and/or etching, may be performed at laser customization station 2430. Additionally, a plurality of embroidery stations 2432 may be used to apply embroidered customization to shoe uppers. In embodiments, shoe components may be embroidered once they are loaded into an embroidery machine. After the embroidery of the one or more shoe components, the shoe components may be unloaded from the embroidery machines. In embodiments, the number of embroidery stations may be one or more, although the utilization of four embroidery stations 2432 as illustrated in
After customization of an upper, forming and stitching module 2406 may form the upper. Forming and stitching module 2406 may receive the customized shoe upper components. The customized shoe upper components may be placed on a flat frame to keep the components in place. The frame may be loaded into a solid state (SS) RF press 2436 to perform RF welding on the components of the shoe upper. Additionally and/or alternatively, the flat frame may be loaded into a heat press 2438. Heat press 2438 may be used to form the upper from heat-activated components. Whether press 2436 and/or press 2438 are used, a press is used to join the components of the shoe upper. Once the shoe components are joined together at press 2436 and/or press 2438, the joined shoe components are cut using shuttle cutter 2440. Shuttle cutter 2440 removes excess material from the joined shoe components. After shuttle cutter 2440 has removed excess material, the joined shoe components are removed from the flat frame. Further, stitching that is desired may be performed to form an upper at stitching stations such as flat-stitch station 2442, zigzag-stitch station 2444, post-stitch station 2448, and gather-stitch station 2454, all of which may be used to stitch shoe components in the form of a shoe upper. Additionally, a hot melt sprayer 2446 may be used to affix shoe components to other shoe components and/or a shoe upper in order to hold components into place as the shoe upper is being formed.
Toe-forming component 2450 may be used in the formation of the toe of an upper. Heel-former component 2452 may be used in the formation of the heel of an upper. Strobel-stitch component 2456 may be used to affix a strobel to a shoe upper for lasting. Toe-condition component 2458 may be used to condition the shoe upper and/or shoe components as part of lasting. For instance, at toe-condition component 2458, the shoe upper and/or shoe components may be exposed to steam to soften the shoe components. Further, lasting component 2460 may be used after the attachment of a strobel to last a shoe upper prior to affixing a midsole and/or outsole. As such, module 2406 may then form the customized shoe upper components into a three-dimensional shoe upper. Further, module 2406 may affix a strobel to the formed shoe upper. Additionally, module 2406 may last the formed shoe upper and strobel.
Midsole and outsole component 2410 may fabricate shoe midsoles and shoe outsoles for use in conjunction with lasted uppers for the assembly of shoes. The midsoles and outsoles may be formed in a variety of fashions and from a variety of materials. Midsoles may be formed from phylon materials, and outsoles may be formed from latex rubber. Possible systems and processes for use in midsole and outsole module 2410 are described elsewhere herein. Midsoles and/or outsoles may be provided to stockfit and assembly module 2408 using a marketplace system, or may be provided on an order-by-order basis.
Stockfit and assembly module 2408 may receive the lasted and formed shoe upper and strobel from the forming and stitching module 2406. Additionally, module 2408 may receive the shoe midsoles and shoe outsoles from midsole and outsole module 2410. Module 2408 may then assemble the shoe midsole, the shoe outsole, and the lasted and formed shoe upper and strobel into a shoe.
In embodiments, midsoles, outsoles, and/or lasted shoe uppers may be received at vented table 2462. At vented table 2462, adhesive may be applied to the bottom of a midsole and to the top of an outsole. The midsole-outsole combination may then be placed into an IR oven such as IR oven 2462. The adhesive on the shoe midsole and the shoe outsole may then be activated at IR oven 2462. The shoe midsole and the shoe outsole may then be set at bladder press station 2466, where the midsole and outsole are pressed together to form a seal. In embodiments, a block press 2468 may be used to press the midsole and outsole together to form a seal.
After the midsole and outsole have been pressed together, the midsole-outsole may be delivered to bite mark machine 2470 to be marked for adhesive. In particular, midsole-outsole may have a shoe upper placed over midsole-outsole to determine the extent of adhesive coverage needed. The midsole-outsole and the shoe upper may then have adhesive applied at vented table 2472. After adhesive has been applied to the shoe upper and to the midsole-outsole in accordance with the bite line, the shoe upper and the midsole-outsole may be placed in IR over 2474. At IR oven 2474, the adhesive applied to the shoe upper and to the midsole-outsole may be activated. The shoe upper and midsole-outsole may then be pressed together at block press 2468. Once a shoe has been formed by pressing together the shoe upper and midsole-outsole, the shoe may be set at chiller 2476. Once the shoe has been set, the shoe may be de-lasted at de-lasting station 2478. Further, the shoe may be checked for quality control and packaged at table 2480.
