Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention without any inventive step, are within the scope of protection of the invention.

Fig. 1 shows a lattice-integrated shoe 100 according to a first embodiment of the present invention. The lattice form 100 includes an upper 110, a sole 120, and an adhesive layer 130. The upper 110 and the sole 120 are coupled together by an adhesive layer. The adhesive layer 130 is a solid structure.

Looking at fig. 2, the upper 110 includes a first patterned area 112, a second patterned area 114, and a third patterned area 116. The first lattice region 112 includes a backside surface. The second lattice region 114 includes a mid-upper and a portion of a front upper. Third patterned area 116 includes a tongue and another portion of a front upper. Sole 120 includes a fourth patterned area 122.

The first lattice region 112 includes a first lattice structure. The first lattice structure is an isotropic structure, has high tensile strength in all directions, and is not easy to damage. Therefore, the back upper including the first lattice structure has a high average strength, and can provide a good supporting function to the upper 110, thereby locking the heel. In this embodiment, the first lattice structure is a hexagram structure, and in other embodiments, the first lattice structure may also be other isotropic structures.

The second lattice region 114 includes a second lattice structure. The second lattice structure is an anisotropic structure, and has a strength in the vertical direction greater than that in the horizontal direction, and ductility in the horizontal direction higher than that in the vertical direction. Thus, the average strength of the mid-upper and a portion of the front upper comprising the second lattice structure is moderate, providing adequate lateral protection, both protecting the foot surface and allowing some mobility, thereby reducing stress on the foot surface. In this embodiment, the second lattice structure is a triangular and rhombic hybrid braided structure, and in other embodiments, the second lattice structure may also be other anisotropic structures.

The third lattice region 116 includes a third lattice structure. The third lattice structure is an anisotropic structure, and has a higher strength in the shoe long axis direction than in the shoe wide axis direction, and a higher ductility in the shoe wide axis direction than in the shoe long axis direction. Therefore, the average strength of the tongue with the third lattice structure and the other part of the front upper is low, the tongue with the third lattice structure has good tensile property, fits with the foot shape, and is convenient for a wearer to put on and take off. In this embodiment, the third lattice structure is an auxetic structure, and in other embodiments, the third lattice structure may also be another anisotropic structure.

Fourth lattice region 122 includes a fourth lattice structure. The fourth lattice structure is a polyhedral structure, and the structure density is moderate, so that the proper weight and excellent resilience of the sole 120 can be ensured. In the present embodiment, as shown in fig. 3, the fourth lattice structure is a hexagonal truncated polyhedron structure based on archimedes, and in other embodiments, the fourth lattice structure may be another polyhedron structure. In addition, the front and rear sole portions of the sole 120 may have different lattice structures, different lattice densities, or different lattice rod diameters, so as to obtain different resilience and support properties.

The crystal-format integrated shoe provided by the embodiment of the invention is manufactured by adopting a 3D printing technology. A 3D printing technique that may be used with embodiments of the present invention is Selective Laser Sintering (SLS). Selective Laser Sintering (SLS) uses primarily an infrared laser as an energy source to shape powdered materials. In the actual production, the powder material is preheated in the first step; when the temperature of the powder material is raised to be slightly lower than the melting point of the powder material, implementing a second step of flattening the powder material by using a scraping roller; thirdly, selectively sintering the powder material after the leveling treatment by using an infrared laser beam under the control of a computer, wherein the selective sintering is mainly operated according to the layered section information provided by the computer, and actually, the sintering operation of the lower layer is generally performed after the sintering of the upper layer is finished; and fourthly, removing redundant powder after all the powder layers are completely sintered, thereby finishing the finished product of the crystal-form integrated shoe manufactured by the 3D printing technology. In addition, in the embodiment of the invention, the 3D printing material of the crystal format integrated shoe adopts thermoplastic polyurethane resin (TPU) powder. Thermoplastic Polyurethane (TPU) is a copolymer of hard and soft block materials that has high tensile and abrasion resistance properties, as well as excellent elasticity and biological identity.

In other embodiments, 3D printing technology for waffle-style shoes may also use Digital Light Processing (DLP). Digital Light Processing (DLP) is mainly used for carrying out digital processing on image signals, and then, carrying out photocuring processing on liquid photopolymer layer by using a high-resolution Digital Light Processor (DLP) projector according to data information so as to finish a crystal-format integrated shoe finished product manufactured by a 3D printing technology. For the 3D printing material of the lattice-type integrated shoe, a Polyurethane (PU) type photo-curable resin material may also be used. Polyurethane (PU) is a polymer with repeating structural units of urethane segments made from the reaction of isocyanate with polyol, and also has high tensile and abrasion resistance properties, as well as excellent elasticity and biological identity.

The upper surface 110 of the lattice-integrated shoe 100 provided by the invention adopts the first lattice region 1112 with the isotropic structure and the second lattice region 114 with the anisotropic structure, so that the lattice-integrated shoe has a multifunctional region structure while realizing an integrated structure, and provides a more comfortable wearing feeling for a wearer.

While the invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that the present invention is not limited to the details of construction and various changes in form and details may be made therein without departing from the spirit and scope of the invention. Accordingly, the scope of the present disclosure is not limited to the above-described embodiments, but should be determined by the claims and the equivalents thereof.
