Description

A 3D arch-cushioning smart insole 3D arch-cushioning smart insole Technical Field

[0001] This invention belongs to the field of insole technology, specifically relating to a 3D intelligent arch cushioning insole. Prior Technology

[0002] When standing, the feet bear approximately 50% of the body weight in static pressure. When walking, the transient pressure on a single foot can reach 2-3 times the body weight. The elasticity of the arch of the foot can absorb more than 90% of the impact force from the ground, protecting the spine, joints, and internal organs from shock damage. If ordinary people have problems such as collapsed arches (e.g., flat feet), it can lead to misalignment of the lower limb force lines, such as the arch, calcaneus, and metatarsals, causing compensatory lesions such as knee valgus and pelvic tilt.

[0003] Insoles, as a crucial connection between the foot and the ground, primarily work in conjunction with the shoe's outsole and midsole, being shaped according to the last or upper plate. Ordinary insoles are flat and lack arch support. While many orthotic insoles are now used in orthopedic and rehabilitation hospitals, these products are typically medical aids, requiring customization based on the patient's arch shape. They are often expensive and unsuitable for most people with insufficient arch strength who do not meet medical criteria. Furthermore, orthotic insoles often cannot balance comfort and versatility. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a 3D arch-supporting smart cushioning insole, which solves the problem of mechanical support for the arch and foot in the prior art, and further solves the problems of comfort and versatility of the insole.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: a 3D arch-shaped smart cushioning insole is provided, including a main body and a surface layer; the main body has an arc-shaped bulge in the area corresponding to the arch, an air cushion is provided inside the arc-shaped bulge, and a supporting rib is provided inside the air cushion; the main body has a central bulge in the area corresponding to the palm, and a magnet is added to the bottom of the bulge; the outer thickness of the main body in the area corresponding to the heel is greater than the inner thickness, and several S-shaped grooves are opened laterally at the bottom of the main body in this area; the surface layer is attached to the upper surface of the main body.

[0006] In a preferred embodiment of this invention, the main body is made of silicone and has several vent holes.

[0007] In a preferred embodiment of this invention, the surface layer comprises titanium silver alloy fiber cloth or graphene conductive fiber cloth, and the cloth is provided with negative ion powder coating and printing treatment.

[0008] In a preferred embodiment of this invention, the forefoot area of ​​the main body is provided with several cutting lines, and the cutting lines have a structure in which the middle section convexes towards the toe of the shoe.

[0009] In a preferred embodiment of this invention, the S-shaped groove protrudes towards the rear edge of the heel near the outer side of the heel and towards the arch of the foot near the inner side of the heel.

[0010] In a preferred embodiment of this invention, the depth of the S-shaped groove is 1 / 5 to 1 / 3 of the thickness of the main body of the area corresponding to the heel.

[0011] In a preferred embodiment of this invention, the inner edge of the arc-shaped bulge is arc-shaped, the outer edge is adapted to the shape of the insole, the included angle of the tangent of the arc is 170°, and the height from the highest point of the arc-shaped bulge to the bottom surface of the main body is no more than 1.8cm.

[0012] In a preferred embodiment of this invention, the supporting ribs are arranged vertically to divide the air cushion into several irregular slots; the top of the slots is closed and the bottom is open.

[0013] In a preferred embodiment of this invention, the central bulge is a circular or elliptical bulge with a smooth transition between its edge and the surface of the main body. A small round hole is provided at the bottom of the back of this part, and a small magnet is placed inside.

[0014] In a preferred embodiment of this invention, the insole is further provided with an edge covering the periphery of the main body and the surface layer.

[0015] This technical solution achieves overall support and cushioning of the insole through the specific structure of each functional area. Compared with previous technologies, it has the following advantages: 1. This solution features an arc-shaped bulge in the arch area, with an internal air cushion containing supporting ribs. This ensures arch support and solves the problem of insufficient elasticity after filling with a single silicone material, achieving elastic and highly adaptable arch support; 2. This solution features a central bulge in the forefoot area, smoothly connecting with the insole surface. This bulge assists in forefoot support, corrects the force line, and neutralizes the abruptness caused by the arch bulge, increasing the comfort of wearing the insole; 3. This solution features a shallow height difference in the heel area, making the outer side slightly higher than the inner side, and designs an S-shaped groove with a specific bending direction, ensuring the required insole thickness in the heel area. 4. This design incorporates cutable lines in the forefoot area to prevent the thin and soft insole from slipping and deforming during walking; 5. This design uses elastomer silicone material with bottom-to-top ventilation holes, allowing the main body to be molded in one piece for easy processing and easy size adjustment, providing excellent adaptability; 6. This design features a surface layer and edging on the main body of the insole, reinforcing the flexible body and maintaining its shape. Furthermore, the use of titanium silver alloy fiber cloth or graphene conductive fiber fabric, with negative ion coating printing, reduces static electricity and releases negative ions, making it smoother and more comfortable to wear; 7. The bottom of the main body features anti-slip textures to prevent the insole from slipping. Simple Explanation of the Diagram

Implementation

[0017] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] This embodiment of a 3D smart arch cushioning insole includes a main body 1, a surface layer 2, and an edging. The main body 1 is made of silicone and has several through-holes 11 extending upwards in a flat, non-functional area (0.2cm thick). The surface layer 2 is attached to the upper surface of the main body 1 and is made of titanium silver alloy fiber cloth or graphene conductive fiber fabric. The edging, approximately 0.3 to 0.4cm wide, covers the periphery of the main body 1 and the surface layer 2. The insole main body 1 has functional areas corresponding to the foot region, specifically including: an arc-shaped bulge 12 in the arch region of the main body 1, the inner edge of the arc-shaped bulge 12 being arc-shaped, the outer edge adapted to the shape of the insole, the included angle of the tangent of the arc being 170°, and the height from the highest point of the arc-shaped bulge 12 to the bottom surface of the main body 1 not exceeding 1.8cm. In this embodiment, an air cushion 13 adapted to the shape of the arc-shaped bulge 12 is provided inside the arc-shaped bulge 12. Several supporting ribs 131 are provided in the vertical direction inside the air cushion 13. The supporting ribs 131 divide the air cushion 13 into several slots 132 of different heights. The top of the slots 132 is closed and the bottom is open, which not only ensures the support of the arch position, but also solves the problem of insufficient elasticity after filling with a single silicone material.

[0019] The main body 1 has a central ridge 14 in the corresponding area of ​​the palm; the central ridge 14 is a circular or elliptical ridge with its edge smoothly transitioning to the surface of the main body 1, with a maximum height of about 0.5cm, which helps to support the foot, correct the force line, and avoid a large height difference caused by the direct connection between the arch ridge and non-functional areas. At the bottom of the back of this part, there is a small round hole with a small magnet inside.

[0020] The thickness (or height) H of the main body 1 on the outer side of the area corresponding to the heel is greater than the thickness (or height) h on the inner side. Several S-shaped grooves 15 are laterally formed at the bottom of the main body 1 in this area. The S-shaped grooves 15 are open at both ends and arranged side-by-side. The S-shaped grooves 15 protrude towards the rear edge of the heel near the outer side of the heel and towards the arch of the foot near the inner side of the heel. The depth of the S-shaped grooves 15 is 1 / 5 to 1 / 3 of the thickness of the main body 1 in the area corresponding to the heel. In this embodiment, the thickness of the main body 1 at the heel is 1.5 cm, the width of a single S-shaped groove 15 is approximately 0.3 cm, and the depth is 0.3 to 0.4 cm. A reinforcing plate 16 can also be provided on the upper surface of the main body 1 from the S-shaped grooves 15 on the outer side of the heel.

[0021] In this embodiment, the thickness of the forefoot area 1 is 0.2cm, and 5 to 6 cutting lines 17 are provided; the cutting lines 17 have a structure with the middle section convex towards the toe of the shoe, which can ensure the shape of the forefoot area, avoid deformation when walking, and also facilitate the insertion of the insole into the shoe.

[0022] The insole of this embodiment can form a mechanical cushioning system in conjunction with the structure of the foot arch, heel bone, metatarsal bones, etc., especially providing elastic support for the arch area. Combined with the cushioning function of other areas, it intelligently adapts to the balance of most human skeletal structures and force lines, achieving good wearing comfort and universality.
