  • Patent number: 11972537
    Abstract: A method for flattening a three-dimensional shoe upper template is provided. The method includes providing a three-dimensional last model, obtaining a three-dimensional grid model, obtaining a three-dimensional thickened grid model, obtaining a two-dimensional initial-value grid model, and obtaining a two-dimensional grid model with the smallest energy value. A system and a non-transitory computer-readable medium for performing the method are also provided. The method makes it possible to precisely flatten a three-dimensional last model with a non-developable surface and thereby convert the three-dimensional last model into a two-dimensional grid model.

  • Publication number: 20240020438
    Abstract: This invention provides a shoe upper design model generating method, system and non-transitory computer readable storage media, including steps of providing a 2D mapping boundary, providing a 3D upper, performing a flattening algorithm on the 3D upper with respect to the 2D mapping boundary, constructing a 2D upper boundary, creating an upper design drawing on the 2D upper boundary, intersecting the 2D upper boundary and the 2D mapping boundary to form a 2D upper design area and mapping grids in the 2D upper design area onto grids in the 3D upper, thereby obtaining an upper design model containing the mapping relation between the 2D upper design area and the 3D upper. Accordingly, the upper pattern making time and cost can be saved, and the distortion and deformation in the process of 2D-3D conversion can be reduced, thus the completed 2D upper design drawing can be used in production process directly.

  • Publication number: 20150010716
    Abstract: A sheetless backlight module and a light guide plate thereof are provided. The light guide plate includes a body and a plurality of light scattering units. The body has a bottom and a plurality of microstructures formed on the bottom and recessed in the body from the bottom. The pluralities of light scattering units are disposed in a plurality of spaces formed due to the plurality of microstructures recessed in the body. A manufacturing method of the light guide plate mentioned above includes forming the plurality of microstructures on the bottom of the body; preparing a fluid solution containing at least a diffusive reflective material; distributing the fluid solution on the bottom; driving the fluid solution to flow into the microstructures; removing the part of the fluid solution outside the microstructures; and solidifying the fluid solution to form the plurality of light scattering units.
