Description

Technical Field

[0001] This invention relates to the field of footwear technology, and more particularly to an NFC-enabled, anti-counterfeiting, washable technological shoe with integrated multiple comfort structures. Background Technology

[0002] Existing footwear products generally suffer from the following defects: First, traditional shoemaking extensively uses polyvinyl acetate emulsion white glue as the composite adhesive between the upper and lining. This glue is prone to delamination and separation when exposed to water, making the shoes unsuitable for washing. After curing, the white glue becomes hard and brittle, causing the adhesive layer to easily peel and curl at points of repeated bending, such as the toe and collar, leading to misalignment and bulging between the lining and upper, severely affecting the appearance and comfort of the shoes. Furthermore, the white glue layer has poor breathability, easily accumulating moisture over time, leading to stuffy and smelly feet. Secondly, conventional shoe tongues mostly have a single, upturned structure, whose contours do not conform to the curve of the human foot, and the material has excess fabric; shoe tongues are mostly semi-pocket-style structures, which have poor performance, and the lace holes of traditional shoe tongues are mostly completely exposed, resulting in a poor overall appearance. Third, ordinary shoes have many seams on the inside, and the seams protrude, which can easily cause friction on the skin of the feet when worn barefoot. This makes people more dependent on socks, and the experience of wearing them barefoot in the summer is poor. Fourth, in existing anti-counterfeiting solutions for footwear, NFC chips can mostly only be placed in one location, resulting in poor product style compatibility; ordinary shoes do not support washing. Fifth, thick-soled and high-top shoes experience high stress in their midsoles and lack suitable auxiliary cushioning midsole structures, while flat shoes lack shock absorption structures. Existing products cannot flexibly adapt cushioning and shaping structures according to style. Existing technologies lack a complete technical solution that combines the above structures while also taking into account washability, detachable and replaceable NFC tags, and integrated foam cushioning and shaping at the toe and heel. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an NFC-enabled, anti-counterfeiting, washable technological shoe with integrated multiple comfort structures, improving technical problems such as impact cushioning at the toe and heel, material buildup on the tongue, discomfort from inner lining seams, glue separation during washing, and the non-replaceable NFC chip. An NFC-enabled, anti-counterfeit, washable technological shoe integrating multiple comfort structures includes an upper, a seamless one-piece lining, a double-curved, double-raised fully wrapped tongue, and a fully wrapped cushioned midsole. The shoe upper, seamless lining, and all composite parts of the shoe collar strap, as well as the layered parts of the fully wrapped cushioning midsole, are all bonded and laminated using environmentally friendly water-based waterproof adhesive (water-based polyurethane adhesive). Traditional polyvinyl acetate emulsion adhesive used in shoemaking is not used. When this environmentally friendly water-based waterproof adhesive gets wet, the composite parts may slightly loosen, but they can be re-kneaded and reattached after the moisture dries. The seamless, one-piece lining is located at the forefoot and instep area of ​​the upper. The shoe opening is integrally molded without any seams. The entire seamless lining fabric body has only one seam, which is located above the instep. The double-curved, double-upturned, fully-covered tongue is fitted onto the instep area of ​​the shoe upper. The tongue features a double-curved, double-upturned, fully-covered design, with the inner lining following suit to eliminate excess fabric buildup. The tongue includes a label area, detachable opening, lace holes, and a center seam. The toe area features both high-elasticity and soft-elasticity sponges, arranged in a staggered pattern. The heel area incorporates a hot-melt adhesive layer and a high-elasticity sponge layer. The shoe tongue has a pre-drilled cavity for holding the NFC tag, which is placed inside the cavity and secured with PU adhesive. The NFC tag can be removed and replaced through a detachable opening. The fully wrapped cushioning insole is combined with the upper of the shoe to form a complete cushioning structure.

[0004] Furthermore, the upper, seamless lining, and double-curved, double-upturned tongue are all made of water-resistant textile fabric.

[0005] Furthermore, the shoe tongue features herringbone reinforcement stitching, with multiple herringbone seams to improve the smoothness of the fabric and reinforce the seams. Furthermore, the toe area features a staggered arrangement of high-elasticity sponge and soft-elasticity sponge, with the soft-elasticity sponge being longer than the high-elasticity sponge. When walking and experiencing compression, the two layers of sponge work together to cushion the impact, eliminating the discomfort of pressure on the toes from the toe area. Furthermore, the heel area uses hot melt adhesive as a shaping layer, with a high-elasticity sponge on the outside, replacing the traditional single chemical sheet or simple hot melt adhesive shaping structure, thus balancing shaping support with heel cushioning comfort. Furthermore, the seamless lining features only one seam above the instep, with no exposed seams elsewhere, allowing for direct wear without socks and preventing ankle chafing. Furthermore, the entire shoe is washable. After washing, the adhesive parts may loosen, but after drying, the adhesive layer can be reattached and restored.

[0006] The beneficial effects of this invention are as follows: First, the present invention features a seamless one-piece lining with only one seam at the instep, eliminating exposed friction seams and allowing for direct wear without socks in summer. The toe area is equipped with high-elasticity sponge and soft-elasticity sponge, while the heel is shaped with a combination of hot melt adhesive and high-elasticity sponge, abandoning the traditional hard chemical sheet. This provides both shaping and cushioning, solving the problem of rubbing against the toes and feet.

[0007] Secondly, all composite areas use water-based polyurethane environmentally friendly waterproof adhesive instead of traditional white glue, allowing the shoes to be washed. After washing, the bonded parts may become loose, but they can be reattached and repositioned after drying to meet the requirements for washable use. At the same time, it avoids the defects of traditional white glue, such as bending, misalignment, lifting, and bulging of the inner lining, and improves the problems of stuffy and smelly feet caused by the sealed adhesive layer.

[0008] Third, the double-curved, double-upturned full-coverage tongue, with the inner lining also upturned, eliminates the accumulation of wrinkles in the tongue material and improves the comfort of wearing the instep; the tongue has a detachable opening, and the NFC tag can be removed and replaced. If the tag is damaged or the traceability information is updated, the tag can be directly replaced without discarding the entire shoe.

[0009] Fourth, this invention combines a seamless lining, tongue, cushioned midsole, and detachable NFC tag, while improving the adhesive system, the double sponge cushioning and shaping at the toe and heel, and the detachable NFC installation structure, to form a complete technological shoe that is washable and has a replaceable traceability chip.

The various composite parts of the upper, seamless one-piece lining, and shoe collar strap, as well as the layered parts of the fully wrapped cushioned midsole, are all bonded together using environmentally friendly water-based waterproof adhesive (water-based polyurethane adhesive), without using traditional polyvinyl acetate emulsion white glue used in shoemaking. When the environmentally friendly water-based waterproof adhesive is wetted, the composite parts may slightly loosen; after the moisture dries, the adhesive layers re-adhere and reposition, enabling the shoe to be washed. The environmentally friendly water-based waterproof adhesive used in this invention is an existing adhesive that can be directly purchased from the market, and this invention does not involve any improvement to the adhesive formulation itself.

[0010] The seamless lining is placed on the forefoot and instep of the shoe, and the shoe opening is molded as a whole without any seams. The seamless lining only has one seam on the instep, and there are no exposed seams in other areas. When wearing the shoes, the seams will not rub against the feet, making them suitable for wearing without socks.

[0011] The double-curved, double-upturned, fully enclosed tongue is fitted onto the instep area of ​​the shoe upper, with the inner lining of the tongue also rising to eliminate fabric buildup and improve wearing comfort. The tongue features: 14-Tongue label, 15-Removal opening, 16-Lace eyelet, 17-Curved hollow upturned seam opening, 18-Curved hollow upturned seam opening, 19-, 20-Herringbone reinforcement stitching, 21-Upper partial shaping splicing position, 22-Full-length splicing seam opening at the bottom. Multiple herringbone stitchings reinforce the fabric and improve its smoothness.

[0012] At the toe area, 7 layers of high-elasticity sponge and 8 layers of soft-elasticity sponge are staggered, with the soft-elasticity sponge being longer than the high-elasticity sponge. When walking, the two layers of sponge cushion the toes when they press against the toe, preventing the hard molding material from squeezing the toes.

[0013] At the heel, 11 hot melt adhesive serves as the shaping layer, with 12 high-elastic sponge on top of the hot melt adhesive layer on the outside, replacing traditional chemical sheets or simple hot melt adhesive, taking into account both heel support and shaping as well as cushioning and comfort. 13 is the shoe opening.

[0014] The shoe tongue has an internal cavity for holding the NFC tag, which is placed inside the cavity. It is partially fixed by PU glue, which only partially seals the tag and leaves room for removal and replacement. No high-temperature hot pressing process is required. If the tag is damaged, it can be removed and replaced through the 15-inch disassembly opening.

[0015] The fully wrapped cushioned midsole and upper are assembled together to provide complete cushioning performance.

[0016] The upper, lining, and tongue of the shoe are all made of water-resistant fabric, and the entire shoe can withstand washing. If the adhesive parts become loose after washing, they can be reattached and restored after drying.
