Description

Technical Field

[0001] This utility model relates to an insole, and more particularly to a 3D printed orthotic insole. Background Technology

[0002] Insoles, as products used in conjunction with shoes, are very common in people's daily lives. They are support pads placed inside the sole of shoes to reduce foot fatigue, absorb shock, provide comfort, and maintain the shape of the shoe. Existing insoles are usually relatively simple in structural design, with limited cushioning performance and the comfort they provide. Moreover, when a whole insole is placed under the sole of the foot, it often hinders the foot's breathability and heat dissipation, making it more likely to cause foot discomfort.

[0003] To address this, people have designed special ventilation holes or even made insoles entirely perforated to improve breathability and heat dissipation. However, if the ventilation holes are too small, the improvement in breathability and heat dissipation is not significant; if the ventilation holes are too large or even entirely perforated, the insole's support function will be greatly reduced, making it difficult to distribute the pressure on the foot and causing problems such as chafing, punctures, or pinching. In addition, conventional insoles cannot be personalized to individual foot shapes and needs, especially lacking the ability to implement soft and hard partitioning, thus failing to help improve foot problems or provide better fit and comfort. Utility Model Content

[0004] Therefore, it is necessary to provide a 3D-printed orthotic insole to address the shortcomings of existing technologies.

[0005] A 3D-printed orthotic insole includes a 3D-printed, one-piece main body, a bottom edge, a top edge, and a support surface. The main body has a mesh-like, openwork design, comprising several interconnected mesh edges, with nodes formed at the ends of adjacent mesh edges. The main body also includes a hard area and a soft area, with the hard area corresponding to acupoints or the arch of the foot. The bottom edge surrounds the bottom edge of the main body, the top edge surrounds the top edge of the main body, and the support surface is located at the top center of the main body and spaced apart from the top edge.

[0006] Furthermore, the hardness of the material in the hard region is greater than the hardness of the material in the soft region.

[0007] Furthermore, the density of the perforated grid in the hard region is greater than the density of the perforated grid in the soft region.

[0008] Furthermore, the support surface is also provided with a hard area, which corresponds to acupoints or the arch of the foot.

[0009] Furthermore, the outer edges of the main body, bottom edge, and top edge are all designed to curl upwards.

[0010] Furthermore, the upper surface of the support surface is provided with anti-slip ridges, which are arranged horizontally.

[0011] Furthermore, the support surface is also provided with several ventilation holes that extend vertically.

[0012] Furthermore, the main body, bottom edge, top edge, and supporting surface are all made of flexible plastic or resin materials.

[0013] In summary, the beneficial effects of this 3D-printed orthotic insole are as follows: The 3D-printed one-piece molding design makes it easier to design and process the hollow structure, thus greatly improving the insole's breathability. Furthermore, the hollow main structure of the insole, combined with the support surface design, provides sufficient support and cushioning for the sole, effectively dispersing the pressure on the foot and significantly improving the insole's comfort. Moreover, the 3D-printed one-piece molding allows for flexible processing and production of insole shapes according to different users' foot shapes, fully meeting the different preferences, habits, and orthotic needs of various users. This utility model is highly practical and has significant potential for widespread application. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the utility model.

[0019] like Figures 1 to 4As shown, this utility model provides a 3D-printed orthopedic insole 100, which includes a 3D-printed integral main body 10, a bottom edge 20, a top edge 30, and a support surface 40. Compared with conventional stitched or injection-molded insoles, the 3D-printed integral molding not only simplifies the production process but also greatly improves the flexibility of processing. It can produce the most suitable insole according to different user preferences and needs, thereby better realizing the orthopedic function of the insole.

[0020] The main body 10 features a mesh-like openwork design, comprising several interconnected mesh edges 11, with nodes 12 formed at the ends of adjacent mesh edges 11. A bottom edge 20 surrounds the bottom edge of the main body 10, and a top edge 30 surrounds the top edge of the main body 10. A support surface 40 is located at the top center of the main body 10 and spaced apart from the top edge 30. The openwork design of the main body 10 provides excellent breathability for the insole, while the combination of the mesh edges 11 and nodes 12 ensures good support. The bottom edge 20 and top edge 30 surrounding the edge of the main body 10 further enhance the overall structural strength of the insole.

[0021] The main body 10 also includes a hard area (not shown) and a soft area (not shown). The hard area of ​​the main body 10 corresponds to acupoints or the arch of the foot. The support surface 40 also has a hard area, which corresponds to acupoints or the arch of the foot. Specifically, in this embodiment, the hardness of the material in the hard area is greater than that in the soft area. The density of the perforated mesh in the hard area is greater than that in the soft area. The design of hard and soft areas of different hardness on the main body 10 and the support surface 40 for acupoints and the arch of the foot not only provides more precise support for the foot but also effectively helps improve foot problems.

[0022] The outer edges of the main body 10, bottom edge 20, and top edge 30 are all designed to curl upwards. This upward-curving insole edge design allows the user's foot to be more fully covered and conformed to the insole when using it, thus improving foot comfort. At the same time, the upward-curving insole shape also provides some restraint and correction to the foot, helping to improve poor foot posture.

[0023] The upper surface of the support surface 40 is provided with anti-slip raised textures 41, which are arranged horizontally. These horizontally arranged anti-slip raised textures 41 increase friction between the foot and the insole, preventing slippage and misalignment during walking, thus avoiding any impact on the corrective effect. The support surface 40 also has several vertically penetrating ventilation holes 42. These ventilation holes 42, combined with the hollowed-out structure design of the main body 10, further enhance the breathability of the insole.

[0024] Specifically, in this embodiment, the main body 10, bottom edge 20, top edge 30, and supporting surface 40 are all made of flexible plastic material. Insoles made of flexible plastic material not only possess excellent elastic cushioning performance but also exhibit strong toughness. Furthermore, it is understood that in other embodiments, the main body 10, bottom edge 20, top edge 30, and supporting surface 40 may also be made of resin or other flexible materials, all of which are within the protection scope of this utility model.

[0025] In summary, the beneficial effects of this 3D-printed orthopedic insole 100 are as follows: The 3D-printed one-piece molding design makes it easier to design and process the hollow structure, thus greatly improving the insole's breathability. Furthermore, the hollow insole's main structure, combined with the support surface 40, provides sufficient support and cushioning for the sole, effectively dispersing pressure on the foot and significantly enhancing the insole's comfort. Moreover, the 3D-printed one-piece molding allows for flexible production of insole shapes according to different users' foot shapes, fully meeting their diverse preferences, habits, and orthopedic needs. This utility model is highly practical and has significant potential for widespread application.

[0026] The embodiments described above illustrate only one implementation of the utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be determined by the appended claims.
