Ergodynamic desktop
A novel concept of ergodynamic desktops with slowly varying configurations for ergonomic purposes is provided. Very slow motions are incorporated into the design of desktops, usually used by computer users. The introduced motion is at such a slow pace that it is hardly noticeable, similar to the adiabatic motions of hour or minute hands on a clock. Users of the desktops are therefore induced to adjust their body posture accordingly in a gradual and healthy manner, while still continuing to perform their normal activities without interruption. These desktop designs allow a natural and effortless combination of normal life and exercise. When used in a working environment, they will be useful to improve the health and to enhance the efficiency of workers.
This application claims priority to U.S. provisional application Ser. No. 60/623,960 filed Nov. 1, 2004 and incorporated herein by reference.
BACKGROUND OF THE INVENTIONA. Field of the Invention
This invention relates to an ergodynamic desktop, allowing users to avoid problems consistent with remaining in the same positions for long periods of time.
B. Description of the Prior Art
Along with the advancement of modern technology, people spend more and more time in front of desks, especially when computers are used. Programmers, secretaries, and many other workers spend long hours each day sitting with a fixed posture in front of a computer, staring at a fixed monitor screen, and typing on a fixed keyboard. This kind of a working habit is known to have notoriously harmful effects on health, causing complaints, serious physical damage, stress, depression, and other illnesses. It is especially tiring for the eyes, resulting in vision reduction. Many companies pay to have their employees treated with massage therapy as means of relaxation from the stressful working conditions.
Various types of desks have been designed in order to optimize the ergonomics of the working environments. However, the great disadvantage of all such designs is that they are limited to static configurations, i.e. the desk is adjusted to an “ideal” position and then fixed, hoping that this position would be the best for the users. It has been realized that, in fact, no “ideal” position is really ideal, as long as the same position is kept long enough. Clinical studies have shown that even if the “best” configurations recommended by the health professionals are chosen, undesired negative effects can result when the users have been kept at these configurations for an extended period of time, as only a limited group of muscles are used and the regions of worn out are not well distributed but rather focused on few localized hot spots. In other words, no configuration is absolutely the best, as long as the configuration remains static.
Therefore, workers get tired in any position if they have to keep the same position for extended periods of time. In addition, with the increased use of computers, requiring their users to have extended working hours with intensive concentration and attention, there are increasingly large numbers of medical problems reported.
Some attempts have been made to design furniture with adjustable configurations to best fit the user's specific need for “optimized” ergonomics: for example, office chairs with several levers for posture adjustments, or computer desks with adjustable height, angle, etc. have been made available on the market. However, these types of furniture still have the problems associated with the furniture that is not adjustable because the adjustable designs are still only adjustable to a limited number of preset positions, with few degrees of freedom, and once these pieces of furniture are adjusted, they still restrict the users to the same static positions.
What is, therefore, needed is a dynamic desktop that will allow its users to gradually and continuously change positions over time so that they are not locked in any one position, which causes fatigue, muscle cramps, eye strain, and other related problems such as back and neck pain and carpal tunnel syndrome.
SUMMARY OF THE INVENTIONThis invention meets the current need for a superior dynamic desktop. A novel ergodynamic desktop is provided by introducing the new concept of slowly varying configurations to dynamic desktops, allowing people to perform physical and mental exercises effortlessly while working at the desktops, and thus reducing the risk of developing related illnesses.
As a highly dynamic system, the human body is in constant physiological motion, e.g. cardiac, respiratory, and gastrointestinal motions, and is best kept healthy with frequent movement and exercise. It is, therefore, very desirable to introduce slowly varying configurations into the designs of furniture. The present invention is designed to have slowly and constantly varying configurations, which are subsequently followed by the user, gradually in a way very much like practicing the oriental exercises of Tai-Chi or Yoga. This type of adiabatic follow up can be considered a form of physical and mental massage, which provides the user with pleasant feelings, as well as greatly reduces tension and stress. For example, different muscle groups will be used and the pressure will be well distributed over broad regions. The long-term effects will be the reduced risks of illness leading to an improvement of physical condition and efficiency of the workers.
Accordingly, it is an object of the invention to provide a dynamically moving desktop to increase the efficiency and productivity of workers, especially workers using computers.
Another object of the invention is to provide a dynamically moving desktop to reduce the strain on workers, especially workers using computers, thus reducing the number of illnesses these workers experience that are related to the use of static desktops.
Still other objects and intentions will become obvious and/or apparent from the following description, drawings and appended claims.
BRIEF DESCRIPTION OF THE DRAWINGSThe features, aspects and advantages of the new ergodynamic desktop will become further understood with reference to the following description, appended claims and accompanying drawings wherein:
The present invention is directed to a novel ergodynamic desktop, used to prevent health problems related to remaining in the same position behind desks for long periods of time and therefore used to improve the efficiency and well-being of workers.
Several specific preferred embodiments of such an ergodynamic desktop, in the form of dynamic computer desktops, are described herein to address the health issues mentioned above. Applying the concept of slowly varying configurations, additive attachments to standard desks are proposed as a simple and inexpensive but effective solution to the problem. These examples are only used to illustrate rather than limit the applications of the invention. The specific design is accomplished with a number of practical considerations, such as cost, ease of use, robustness, and simplicity. Numerous variations, combinations, extensions, and improvements of these designs are possible, based upon the general principles disclosed, which are impossible to list here exhaustively.
One preferred embodiment of the ergodynamic desktop is shown in
Another preferred embodiment is shown in
As said previously, the assembly 10 can be separated into two component parts, a lower tray 20 that has a baseboard 70 (the bottom surface of the lower tray 20, see
The slow moving motors 80 and 220 can be either DC or AC type, or they could be stepping motors. The stepping motor is particularly suited for a computer desktop because the motor can be controlled by software run on the computer. The user can then easily choose the style of the motion and even develop user-defined programs to control the movements in a desired fashion. Motion parameters such as direction, amplitude, and speed can all be easily altered at the user's discretion.
The ergodynamic desktop described above is only one of many inventive possibilities. The descriptions on the preferred embodiments are only intended to serve as illustrations rather than limitations of the invention. Variations, modifications, and extensions are unlimited based on the general principles of the invention.
For example, the present invention may further incorporate dynamic motion into the design of the computer monitor itself. The latest model monitor using a liquid crystal display (LCD) screen is particularly suited for such designs, since the significantly reduced weight and size would allow various types of motion, including nodding, tilting, left-and-right turning.
Indeed, to achieve the same goals as the ergodynamic desktop of the invention, it is not necessary to create special hardware at all. Software approach sometimes can do even better. For example, the display on a computer screen can be easily made a lot healthier by introducing the concept of slow varying configurations. Today, most computer software applications use framed display areas called “windows.” These windows usually occupy only part of the entire screen, leaving some room for possible movement. It is conceivable to have a display option of any software as turning “on” or “off” a drifting function of the windows. At most times, the drifting function is “on”, but it can be easily turned off when performing careful tasks such as detailed drawing, etc.
Besides the location of windows, many other parameters or configurations of a computer display can be easily made slowly varying, given the tremendous flexibility and possibilities in computer programming. Candidates of these parameters include font size, color, brightness, contrast, or even focus. A slightly defocused but dynamically drifting display might be healthier than a very sharp but static one. In fact, many types of display software that constantly vary these parameters have already been developed for years. They serve some other purposes however, and are typically called “screen savers,” but similar techniques can protect the people's eyes as well.
Another very important application of the concept of slowly varying configurations is environment control. People usually try to find the most comfortable parameter settings (such as temperature), keeping the environment at these parameter levels. As briefly discussed before, this philosophy may not necessarily be healthy. Human bodies are very different from machines. They are naturally capable of adjusting themselves to follow the environment. More importantly, they need constant variations, stimuli, massages, and exercise to keep alive. Therefore, slowly varying a large family of parameters may be beneficial to a human body. A partial list of these parameters is given below: temperature, humidity, air pressure, airflow, oxygen level, dust concentration, gravity, magnetic fields, and even noise levels. (It has been reported that absolute silence can drive people crazy.) One thing is almost certain, the healthiest settings must be dynamic.
The scope of the invention will now be indicated in the claims.
