[0048] Example

[0049] This application relates to footwear products, which are typically worn to provide protection and support for the feet, and also serve an aesthetic and comfortable purpose. Footwear products are divided into standard-sized products and customized products. Standard-sized products offer a range of sizes for wearers to choose from, while customized products are manufactured specifically according to the wearer's foot size and shape. To reduce the production cost of footwear products and improve the convenience of customized product production, patent documents "CN113367437A Footwear Product with Upper Including Wrapping Components and Method for Manufacturing the Same" and "CN204207163U Processing Components and Weaving Components for Forming Uppers" both provide processing methods for forming uppers by yarn weaving. It is understood that yarn weaving for upper production is applicable to both standard-sized and customized footwear products. For customized footwear production, the automated weaving method provided in patent document "CN114960022A Intelligent Data Encoding Footwear Weaving Method and System Based on Industrial Digital Intelligence" can significantly improve production efficiency.

[0050] The footwear products provided in the embodiments of this application are described in [reference]. Figure 1The shoe includes a sole 100 and an upper 200 woven from knitted threads. First-type positioning posts 101 are distributed around the edge of the sole. During the knitting process of the upper, the knitted threads connect to the sole by wrapping and knotting with the first-type positioning posts, creating a movable or fixed connection. This allows the upper and sole to jointly define the footwear for accommodating the foot. The footwear provided in this application, by setting first-type positioning posts on the sole and utilizing the knitting characteristics of the upper, allows the knitted threads to directly connect to the first-type positioning posts during the knitting process, thus directly connecting the upper to the sole. Compared to existing technologies, this reduces manufacturing steps and improves production efficiency.

[0051] To facilitate the direct weaving of the upper onto the sole, a central support is often needed to define the shape of the upper and provide spatial positioning posts. See [link / reference needed]. Figure 2 In the footwear manufacturing method provided in this application, a central support member 300 is provided on the sole 100; preferably, the central support member can be a foot mold (including a mold similar to a shoe last); the outer contour of the central support member roughly defines the shape of the upper. When producing customized products, the central support member can be customized according to the size and shape of the wearer's foot. Second-type positioning posts 301 are distributed on the central support member 300, and the upper is formed by weaving, connecting, and / or continuing the weaving threads between the first-type positioning posts 101 and the second-type positioning posts 301, between the second-type positioning posts and the second-type positioning posts, and between the first-type positioning posts and the first-type positioning posts.

[0052] In some embodiments, the first type of positioning posts are distributed around the edge of the sole. These posts are protruding structures extending from the sole. For example, the first type of positioning posts and the sole are prefabricated as a single unit. They are formed as a prefabricated unit using conventional materials such as foam, rubber, gel, thermoplastic elastomer (TPE), ethylene-vinyl acetate (EVA), expanded thermoplastic polyurethane (eTPU), expandable polyether block amide (ePEBA), thermoplastic rubber (TPR), thermoplastic polyurethane (TPU), or a mixture of several conventional materials, through processes such as injection molding, foaming, or compression molding. It is understood that the materials used for the first type of positioning posts and the sole are not limited to a single material.

[0053] In some other embodiments, the first type of positioning post and the sole are 3D printed as a single piece, and the materials of the first type of positioning post and the sole are not limited to one material.

[0054] In a further embodiment, the first type of positioning post, as a raised structure surrounding the sole, protrudes radially away from the center of the sole. The first type of positioning post is made of a thermoplastic material. After the woven yarn forms the upper, the first type of positioning post is thermoplasticized and pressurized from both sides of the sole using a mold, causing the raised structure to fuse with the sole. This fixes the woven yarn and the upper formed by the woven yarn, resulting in a smooth sole surface. Thus, the first type of positioning post can be molded without additional trimming.

[0055] In optional embodiments, the second type of positioning post can be a pin, protrusion, or block attached to the central support member. In some embodiments, the second type of positioning post is a removable pin, which can be easily removed after the upper is woven, allowing the central support member to be taken out. In other embodiments, the second type of positioning post is made of a heat-fused material, and the second type of positioning post is attached to the central support member by a pin penetrating the post. After the upper is woven, the pin is removed, and the second type of positioning post becomes part of the upper.

[0056] Traditional footwear typically requires a more robust heel counter to reinforce the shoe, provide overall support, and prevent deformation. In this embodiment, the footwear may also include a prefabricated heel counter, see [link to relevant documentation]. Figure 3-1 and Figure 3-2 Both the heel counter 400 and the sole 100 are prefabricated components. The heel counter 400 is directly connected to the sole 100. The heel counter 400 and the sole 100 can be fixed by means of sewing, gluing, hot pressing, fixing nails, etc. The heel counter 400 is provided with third-type positioning posts 401. By wrapping, connecting and / or continuing the weaving thread between the first-type positioning posts and the third-type positioning posts, between the first-type positioning posts and the second-type positioning posts, between the second-type positioning posts and the third-type positioning posts, between the first-type positioning posts and the first-type positioning posts, between the second-type positioning posts and the second-type positioning posts, and between the third-type positioning posts and the third-type positioning posts, the upper is woven into a whole while the upper is connected to the heel counter 400 and the sole 100.

[0057] Similar to the 400 heel counter, other footwear accessories such as toe caps, tongues, and eyelets can be added in a similar manner. These can all be prefabricated and positioned into the upper during the weaving process using knitting threads. More specifically, for example, the tongue and eyelets can be pre-set in slots in the central support component, with positioning posts made of hot-melt material connected to them. The knitting threads connect to these positioning posts during the upper weaving process. Alternatively, the knitting threads can overlap the upper with the tongue and eyelets during the weaving process, and then be fixed together using adhesives, heat pressing, or other methods.

[0058] In some implementations, see Figure 4The second type of positioning stakes 301 are distributed near the top layer of the central support 300. The braided thread is wound, connected, and / or continued between the first and second type of positioning stakes, between the second and third type of positioning stakes, and between the first type of positioning stakes. See [link to documentation]. Figure 4 , Figure 5 The weaving patterns include N-type and V-type weaving, among others. Through various weaving methods, multiple layers of the upper can be woven onto the surface of the central support component, increasing the density of the weaving threads forming the upper. The density of the upper can also be described by the coverage ratio. Taking any area of ​​the upper, the area covered by the weaving threads divided by the area of ​​that area is the coverage ratio. A higher coverage ratio indicates a denser weaving pattern in the upper.

[0059] Understandably, when the second type of positioning stake 301 has only one layer, it is difficult to increase the density of the shoe upper by changing the routing method. In a further implementation, see... Figure 6 The second type of positioning posts distributed on the central support are set in two or more layers (positioning posts are set at different height positions relative to the sole). As the number of positioning post layers increases, various weaving patterns can be formed on the shoe surface by designing weaving stitches. Pre-made patterns can also be added during the weaving process, making the shoe surface more personalized and improving its aesthetics.

[0060] In some implementations, see Figure 7 Near the sole 100, the upper 300 includes an edge weave structure formed by woven threads. This edge weave structure comprises multiple upward-opening parabolas 302 formed by bending multiple segments of woven threads. The apexes of these parabolas are located on the same virtual indicator line 102 near the sole. This virtual indicator line serves as a boundary between the upper and sole; it is not a physical concept and is not necessarily at the height of the first type of positioning post. By forming continuously distributed parabolas, the edges of the upper are clearly defined, improving aesthetics. The parabolas can be formed by fixing both ends to a higher second type of positioning post, allowing the parabolas to hang freely downwards. By adjusting the positions of the ends and the length of the parabolas, the apexes of each parabola are located on the same virtual indicator line on the sole. Alternatively, they can be fixed to the first type of positioning post, with shorter parabolas used to adjust the distribution of the upper edges.

[0061] In a further implementation, see Figure 8The parabolas intersect with adjacent parabolas to form multiple intersection points. An internal fixed-point structure 303 is also provided inside the shoe upper. This internal fixed-point structure refers to a structural component located at a fixed point in the non-edge area of ​​the shoe upper's internal region. Examples include knots formed by knotted braided threads, second-type positioning posts at fixed points, or prefabricated ring-shaped structural components, primarily used for positioning. Starting from the internal fixed-point structure, at least one braided thread surrounds the multiple intersection points, tightening and converging several local parabolas. The lengths of these local parabolas are adjusted so that their apexes remain on the virtual indicator line. These local parabolas can use more elastic braided threads, thus forming a local bundle of threads. This bundle is often vertical, thereby forming a reinforcing bundle 304 that tightens the shoe upper and sole locally.

[0062] In some embodiments, the braided yarn involved in this application can be made of a single material such as polyurethane, nylon, high molecular weight polyethylene, fiber, aramid, etc., or it can be made of composite materials or composite structures. For example, the braided yarn is a composite yarn, including an inner core and a surface hot-melt layer. When braided yarn with a hot-melt layer or hot-melt yarn is used directly as the braided yarn, after the upper is woven, the braided yarn can be fused together by applying pressure and heat with a mold to fuse the relatively mesh-like upper to form a complete upper.

[0063] See Figure 9 , Figure 10 The sole is set on the bottom mold 500, with the left mold 600 and right mold 700 on both sides of the sole cooperating with each other. The central support member supports the upper inside the upper after the removal of the second type of positioning post. The upper mold 800 cooperates with the central support member 300 from above to define the upper space. The upper is fused together by the molds under pressure and heat to form a complete upper. At the same time, for the first type of positioning post using hot-melt material on the edge of the sole, the left and right molds heat-melt and press the first type of positioning post to fuse it with the sole, thereby fixing the upper and sole to form a finished structure, and the surface of the sole can be formed into a flat surface.

[0064] In some embodiments, the footwear products provided in this application also include a prefabricated forefoot panel 900, which is connected to the sole 100, or the sole and forefoot panel are directly prefabricated as a single unit. For example, the sole and forefoot panel can be directly printed using 3D printing to make them a single structural component. It is understood that the sole and forefoot panel can be made of the same material or different materials. Similarly, a fourth type of positioning post 901 is provided on the forefoot panel, and the woven threads of the upper are connected to the fourth type of positioning post through winding, knotting, or other movable connections, or directly bonded or heat-fused connections, to connect the upper to the forefoot panel.

[0065] In a further embodiment, the fourth type of positioning post is similar to the first type of positioning post, and is also selected as a raised structure made of hot melt material. By using a mold to hot melt and press the fourth type of positioning post, the fourth type of positioning post can be fused with the front upper, thereby fixing the braided thread and the shoe upper formed by the braided thread, and the surface of the front upper is formed into a flat surface.

[0066] The above description is merely a preferred embodiment of this application and does not constitute any limitation on this application in any form or substance. It should be noted that those skilled in the art can make several improvements and additions without departing from this application, and these improvements and additions should also be considered within the scope of protection of this application. Any modifications, alterations, and equivalent variations made by those skilled in the art based on the disclosed technical content without departing from the content and scope of this application are equivalent embodiments of this application. Furthermore, any equivalent changes, alterations, and variations made to the above embodiments based on the essential technology of this application still fall within the scope of the technical solution of this application.
