[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0021] The following detailed description of the 3D-printed insole that improves foot support, in conjunction with the accompanying drawings and embodiments, is provided in detail.

[0022] like Figure 1 , Figure 2 As shown, this utility model provides a 3D-printed insole that improves foot support. The insole body 1 is a one-piece design, which ensures the insole's integrity and structural stability. The insole body 1 is manufactured using 3D printing technology, which allows for precise control of its shape, size, and internal structure to adapt to different foot shapes and sizes. The insole body 1 has a support part 11 at the arch, which is precisely constructed using 3D printing technology to provide accurate support for the foot. During the manufacturing process, a foot scanning device can be used to model the foot beforehand, making the manufactured insole fit the foot more closely. The 3D-printed insole can use TPU material to ensure sufficient toughness.

[0023] The design of the stepped cavity 2 and the supporting elastic block 3: the stepped cavity 2 is arranged inside the supporting part 11, which is designed to reduce the weight of the insole and improve the elasticity. The stepped cavity 2 includes a first stepped part 21 and a second stepped part 22, the first stepped part 21 is located below the second stepped part 22, and the cross-sectional area of the first stepped part 21 is larger than that of the second stepped part 22. Such a design makes the supporting part 11 produce better deformation and rebound effect when subjected to pressure. The first stepped part 21 extends to the edge of the supporting part 11 near the middle, providing a stable support base for the arch of the foot; the second stepped part 22 extends to the middle of the supporting part 11, further enhancing the elasticity and comfort of the supporting part 11.

[0024] At the bottom of the stepped cavity 2, the supporting elastic block 3 is arranged. These supporting elastic blocks 3 are rectangular blocks in shape, which can effectively disperse and absorb the pressure from the foot. The outer side of the supporting elastic block 3 is provided with a triangular notch 31, which makes the supporting elastic block 3 produce more complex deformation when subjected to pressure, thereby providing better elastic effect. The tip of the triangular notch 31 extends to the middle of the supporting elastic block 3, and the opening of the triangular notch 31 gradually decreases from the edge to the middle of the supporting elastic block 3. This design ensures the stability and uniformity of the supporting elastic block 3 during deformation.

[0025] The layout and connection of the supporting column 4: on the supporting elastic block 3, a plurality of supporting columns 4 are arranged. One end of these supporting columns 4 is connected to the top of the stepped cavity 2, and the other end is closely attached to the supporting elastic block 3. One end of a plurality of supporting columns 4 is connected to the first stepped part 21, and because the cross-sectional area of the first stepped part 21 is larger, it can carry more supporting columns 4, thereby providing more stable support. The number of supporting columns 4 whose other end is located above the triangular notch 31 is more than the number of supporting columns 4 whose other end is located inside the supporting elastic block 3. This layout makes the supporting force more concentrated above the triangular notch 31, enhancing the support effect and elasticity of the arch of the foot.

[0026] Further, one end of a plurality of supporting columns 4 is connected to the second stepped part 22. Because the cross-sectional area of the second stepped part 22 is smaller and extends to the middle of the supporting part 11, the number of supporting columns 4 connected to the second stepped part 22 is relatively small. However, the number of supporting columns 4 whose other end is located above the triangular notch 31 is less than the number of supporting columns 4 whose other end is located inside the supporting elastic block 3. This design makes the supporting force more evenly distributed inside the supporting elastic block 3, thereby improving the comfort of wearing.

[0027] The number and layout of the support elastic blocks 3 and the support columns 4: Preferably, the support elastic blocks 3 are provided with three, which is a carefully designed number, which can provide sufficient support force without making the insole too bulky. Each of the support elastic blocks 3 is provided with at least six support columns 4, which are staggered and inclined at an angle to better adapt to the curved shape of the arch. The staggered arrangement of the support columns 4 ensures uniform distribution of support force on the support elastic blocks 3, while the inclined arrangement makes the transmission of support force more smooth, effectively reducing foot pressure.

[0028] The shape and size of the support part 11 are optimized: The upper part of the support part 11 extends outward, forming a unique wrap-around design. This design not only increases the beauty of the insole, but also improves the comfort of wearing. By extending outward, the support part 11 can better fit the shape of the arch and provide more comprehensive support to the foot. At the same time, the width of the insole body 1 below the position of the support part 11 is less than the width above, which makes the insole more fit the foot when worn, reducing unnecessary friction and pressure. The plane of the secondary step 22 is located on the outside of the support elastic block 3, which further enhances the stability and support effect of the support part 11.

[0029] The 3D printed insole for improving foot stress of the utility model provides more appropriate and accurate support force for the foot by optimizing the arch support structure and adopting the design of the stepped cavity 2 and the support elastic block 3. At the same time, by accurately controlling the number, layout and inclination angle of the support columns 4, and optimizing the shape and size of the support part 11, the wearing comfort and health of the insole are further improved.
