Description

Technical Field

[0001] This invention relates to the field of children's orthopedic insole technology, specifically to a mortise and tenon dynamic reconstructed children's orthopedic insole based on growth prediction. Background Technology

[0002] The development of children's feet exhibits significant stage-specific characteristics. It is a dynamic and continuous process of change. The development of the arch of the foot usually begins rapidly and takes initial shape between the ages of 6 and 8. However, the complete maturation and stability of this crucial structure is not achieved until around the age of 12. Throughout this critical growth and development stage, the internal structure of children's feet undergoes a complex and delicate shaping process. The skeletal structure is constantly reshaped during growth, the ligaments gradually strengthen through exercise, and the muscle tissue develops and improves its function in sync. All these elements are continuously and collaboratively adjusting to lay a solid foundation for a stable and healthy foot shape in the future.

[0003] Most existing orthopedic insoles adopt an integrated fixed structure design. The arch support component and the insole body are usually glued or thermoformed. Once the insoles are made, they cannot be adjusted according to the growth changes of children's feet. This integrated design requires parents to frequently change the entire pair of insoles to match different correction stages, which not only greatly increases the cost of use, but also affects the correction effect due to repeated adaptation to new insoles. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a mortise and tenon type dynamic reconstructed orthotic insole for children based on growth prediction, solving the problem of needing to replace the entire insole when adjusting a child's arch.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mortise and tenon type dynamic reconstructed children's orthopedic insole based on growth prediction, comprising an insole base, an installation component provided on one side of the insole base, the installation component including a positioning groove, the positioning groove being opened on one side of the insole base, a plurality of limiting grooves being opened on one side of the insole base, a heel pad being fixedly installed on the inner side of the positioning groove, a buckle being fixedly installed on the inner side of the limiting groove, and an insole cushioning layer being fixedly installed at one end of the heel pad.

[0006] Preferably, the insole cushioning layer has multiple ventilation holes on one side, and a raised support column is installed inside the ventilation hole. One end of the raised support column is fixedly connected to the insole contact layer, and the insole contact layer and the insole cushioning layer are connected through the raised support column and the ventilation holes.

[0007] Preferably, a dynamic rigid arch is installed at one end of the insole base, and a placement groove is provided on one side of the insole cushioning layer. The dynamic rigid arch corresponds to the shape of the placement groove, and one end of the dynamic rigid arch is installed inside the placement groove.

[0008] Preferably, one of the positioning grooves and limiting grooves is formed on one side of the insole cushioning layer, and the positions of the positioning groove and limiting groove formed on the insole cushioning layer and the insole base correspond to each other.

[0009] Preferably, the outer wall of the heel pad and the buckle is provided with multiple tenons, which are evenly distributed on the outer wall of the heel pad and the buckle, and the tenons are mortised and tenoned with the corresponding mortises on the positioning groove and the limiting groove.

[0010] Preferably, the raised support columns are evenly distributed on one side of the insole cushioning layer, the raised support columns correspond to the positions of the ventilation holes, and the diameters of the raised support columns and ventilation holes are the same.

[0011] Preferably, the insole contact layer and the insole cushioning layer have the same shape, the insole base has the same shape as the rear end of the insole cushioning layer, and the insole contact layer, the insole cushioning layer, and the insole base are stacked in the vertical direction.

[0012] Preferably, the diameter of the protruding support post is the same as that of the vent hole, and the length of the protruding support post is the same as that of the vent hole.

[0013] Working Principle: This children's orthopedic insole is composed of a vertically stacked insole contact layer 1, an insole cushioning layer 2, and an insole base 3. Positioning grooves 4 and limiting grooves 5, corresponding to the positions of the insole base 3 and the insole cushioning layer 2, respectively engage with the tenons on the outer walls of the heel pad 6 and the buckle 7, achieving a stable and detachable connection between the two layers. The insole contact layer 1 is elastically spliced ​​by protruding support pillars 9 embedded in the ventilation holes 10 of the insole cushioning layer 2. The diameter and length of the protruding support pillars 9 and the ventilation holes 10 are identical, ensuring a snug and stable connection. The dynamic arch support 8 on the insole base 3 precisely matches the shape of the placement groove 11 of the insole cushioning layer 2 and is embedded within it, relying on the overall mortise and tenon detachable structure. The dynamic hard arch support 8 can be quickly disassembled and replaced according to the stage changes in the growth and development of children's feet. The support strength of the arch correction can be flexibly adjusted without replacing the entire insole, so as to achieve dynamic adaptation between the correction plan and the growth of children's feet and ensure the continuity of the correction effect. The insole contact layer 1 and the insole cushioning layer 2 form elastic multi-point support through evenly arranged convex support columns 9, which can evenly distribute the pressure on children's feet, reduce local pressure, and ensure the support force required for arch correction. The combination of convex support columns 9 and ventilation holes 10 forms a multi-layer ventilation channel, allowing air to flow smoothly between the foot and the insole, improving breathability, reducing the stuffiness of wearing for a long time, and balancing the support of correction and wearing comfort.

[0014] This invention provides a mortise and tenon dynamic reconfiguration orthotic insole for children based on growth prediction. It has the following beneficial effects: 1. This invention uses a mortise and tenon detachable connection structure to enable quick replacement of insoles for dynamic hard arches, allowing parents or medical staff to flexibly adjust the corrective support according to the stage changes in the child's foot growth and development. The corrective solution can be dynamically adapted without replacing the entire insole, reducing the cost of long-term use of corrective insoles.

[0015] 2. This invention adopts a layered breathable structure and a multi-point support design. The insole contact layer is elastically connected to the insole cushioning layer through the convex support columns, which improves breathability while ensuring corrective support. The array distribution of the convex support columns makes the pressure evenly distributed, reduces local pressure, and improves the comfort of children wearing the shoes for a long time.

[0018] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0019] Please see the appendix Figure 1 -Appendix Figure 4This invention provides a mortise and tenon type dynamic reconstructed children's orthodontic insole based on growth prediction, including an insole base 3. An installation component is provided on one side of the insole base 3. The installation component includes a positioning groove 4, which is opened on one side of the insole base 3. A plurality of limiting grooves 5 are opened on one side of the insole base 3. A heel pad 6 is fixedly installed on the inner side of the positioning groove 4. A buckle 7 is fixedly installed on the inner side of the limiting groove 5. An insole cushioning layer 2 is fixedly installed on one end of the heel pad 6.

[0020] Specifically, by setting an installation component containing a positioning groove 4 and a limiting groove 5 in the insole base 3, and installing a matching heel pad 6 and a buckle 7 to connect the insole cushioning layer 2, a basic mortise and tenon assembly structure is constructed, realizing the detachable and stable connection of the core layer of the insole. This provides assembly support for the dynamic adjustment of the subsequent orthopedic structure, breaking the fixed structure limitations of traditional integrated insoles, and facilitating targeted replacement and maintenance of the arch correction components at different stages of a child's life.

[0021] Please see the appendix Figure 3 -Appendix Figure 5 The insole cushioning layer 2 has multiple ventilation holes 10 on one side. A raised support column 9 is installed inside the ventilation hole 10. One end of the raised support column 9 is fixedly connected to the insole contact layer 1. The insole contact layer 1 and the insole cushioning layer 2 are connected through the raised support column 9 and the ventilation hole 10.

[0022] Specifically, the insole contact layer 1 and the insole cushioning layer 2 are connected by ventilation holes 10 and raised support columns 9. The raised support columns 9 form an elastic support structure, providing uniform support for children's feet, reducing local pressure, and improving wearing comfort. The ventilation holes 10, in conjunction with the connection method of the raised support columns 9, form ventilation channels, enhancing the breathability of the insole and preventing children from experiencing stuffiness after wearing it for a long time. At the same time, the matching design of the raised support columns 9 and ventilation holes 10 ensures the fit and stability of the connection between the contact layer and the cushioning layer, so that the support and breathability functions are combined and the structure is sturdy.

[0023] Please see the appendix Figure 3 and attached Figure 4 A dynamic hard arch 8 is installed at one end of the insole base 3. A placement groove 11 is provided on one side of the insole cushioning layer 2. The dynamic hard arch 8 corresponds to the shape of the placement groove 11. One end of the dynamic hard arch 8 is installed on the inner side of the placement groove 11.

[0024] Specifically, the dynamic hard arch 8 is precisely matched and installed with the placement slot 11, making the dynamic hard arch 8 an independently detachable core correction component. With the overall structure, the dynamic hard arch 8 can be quickly replaced. It can flexibly adjust the support strength of the arch correction according to the stage changes in the growth and development of children's feet, without the need to replace the entire insole, ensuring the dynamic adaptability of the correction plan and the continuity of the correction effect. At the same time, the precise installation design also makes the installation of the dynamic hard arch 8 more stable and the correction support more reliable.

[0025] Please see the appendix Figure 2 -Appendix Figure 4 One of the positioning grooves 4 and the limiting groove 5 is opened on one side of the insole cushioning layer 2, and the positioning groove 4 and the limiting groove 5 opened on the insole cushioning layer 2 and the insole base 3 are in corresponding positions.

[0026] Specifically, positioning grooves 4 and limiting grooves 5 are made at corresponding positions on the insole cushioning layer 2 and the insole base 3, so that the positioning points of the tenon and mortise connection correspond precisely on the two-layer structure. This ensures the accuracy of the alignment when assembling the insole cushioning layer 2 and the insole base 3, making the layer connection more precise and stable. It avoids assembly misalignment from affecting the correction effect and wearing experience. At the same time, the uniform and corresponding grooves make disassembly and assembly operations more convenient and improve the efficiency of insole component replacement and adjustment.

[0027] Please see the appendix Figure 4 and attached Figure 6 The outer walls of the heel pad 6 and buckle 7 are provided with multiple tenons. The tenons are evenly distributed on the outer walls of the heel pad 6 and buckle 7. The tenons are connected to the corresponding mortises on the positioning groove 4 and the limiting groove 5 by tenon and mortise.

[0028] Specifically, by setting evenly distributed tenons on the outer wall of the heel pad 6 and buckle 7, a tenon-and-mortise connection is formed with the mortises of the positioning groove 4 and the limiting groove 5, replacing the traditional adhesive and hot-press fixing method. This achieves a detachable and stable connection between the insole layers, making disassembly and assembly simple and convenient. Parents or medical staff can easily adjust and replace the insole according to the child's foot development. Moreover, the tenon-and-mortise structure has strong connection stability, can adapt to the force requirements of children's daily activities, extend the service life of the insole, and reduce the cost of orthodontic use.

[0029] Please see the appendix Figure 4 and attached Figure 5 The raised support columns 9 are evenly distributed on one side of the insole cushioning layer 2. The raised support columns 9 correspond to the positions of the ventilation holes 10, and the diameters of the raised support columns 9 and the ventilation holes 10 are the same.

[0030] Specifically, the raised support columns 9 are evenly distributed on one side of the cushioning layer 2 of the insole and are precisely aligned with the ventilation holes 10 with the same diameter. This ensures that the support force of the raised support columns 9 on the insole contact layer 1 is evenly distributed on the child's foot, effectively dispersing foot pressure, reducing discomfort caused by local pressure, and improving comfort during long-term wear. At the same time, the consistent diameter design makes the connection between the raised support columns 9 and the ventilation holes 10 tighter, preventing loosening or displacement during use and ensuring the stability of the support structure.

[0031] Please see the appendix Figure 3 and attached Figure 4 The insole contact layer 1 and the insole cushioning layer 2 have the same shape, and the insole base 3 has the same shape as the rear end of the insole cushioning layer 2. The insole contact layer 1, the insole cushioning layer 2 and the insole base 3 are stacked in the vertical direction.

[0032] Specifically, the insole contact layer 1 and the insole cushioning layer 2 have the same shape, and the insole base 3 has the same shape as the rear end of the insole cushioning layer 2. The three layers are arranged vertically, so that the overall structure of the insole can adapt to the contour of the child's foot, conform to the shape of the foot, improve the fit and comfort of wearing, and avoid local compression caused by structural misalignment. At the same time, the vertical stacking design makes the force transmission of each layer structure more even, ensuring the effective performance of the corrective support.

[0033] Please see the appendix Figure 4 and attached Figure 5 The diameter of the protruding support column 9 is the same as that of the vent hole 10, and the length of the protruding support column 9 is the same as that of the vent hole 10.

[0034] Specifically, the length of the raised support column 9 is the same as that of the ventilation hole 10. After the raised support column 9 is embedded in the ventilation hole 10, a uniform gap is formed between the insole contact layer 1 and the insole cushioning layer 2. This not only ensures that the raised support column 9 provides effective elastic support to the contact layer, making the support force more evenly transmitted, but also allows the gap to form a continuous ventilation channel, improving the overall breathability of the insole. At the same time, the consistent length design avoids the problem of the raised support column 9 being too long and protruding or too short and causing insufficient support, ensuring the flatness of the insole structure and the effectiveness of support, further improving wearing comfort and corrective reliability.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
