Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of insoles, and particularly relates to a mortise and tenon jointed modular 3D orthotic insole. Background Art
[0002] An insole is a cushion placed at the bottom inside of a shoe, mainly used to increase comfort, absorb sweat, keep warm, increase height, etc. The materials of insoles include cloth, leather, silica gel, TPR, etc. Different materials have different characteristics and comfort levels. For example, cotton is breathable and moisture-absorbing, bamboo is environmentally friendly and antibacterial, leather is high-grade and wear-resistant, and silica gel has elasticity and compressive resistance. According to functions and application fields, insoles can be divided into cushion buffer series, stability stable series, etc., designed for different sports types and populations to meet different needs. In Chinese folklore, the embroidery decorations on insoles are often rich in meanings, expressing the good wishes and ideals of relatives. For example, "continuous offspring" symbolizes the continuous spread of descendants for generations. Insoles are also sold as a commodity, designed by developers and circulated in the market. Consumers can choose according to their personal needs and preferences;
[0003] 3D printing, that is, three-dimensional printing, is also called additive manufacturing technology (AM). It is a technology for manufacturing solid parts by the method of layer-by-layer material accumulation based on three-dimensional CAD data. 3D printing is based on digital model files and uses bondable materials such as powdered metal or plastic. These "printing materials" are installed in the printer. After being connected to the computer, the materials are stacked layer by layer through computer control, and finally the blueprint on the computer becomes a physical object. 3D printing technology has been applied in many fields, such as manufacturing clothing, architectural models, automobiles, chocolate desserts, etc., and can even directly print out parts for the manufacture of some products.
[0004] In addition to the above functions, insoles also have a corrective function. However, the current insoles have fixed specifications and cannot be changed according to the rehabilitation situation and body shape changes of patients. Repeatedly purchasing new insoles will undoubtedly increase the economic cost, especially in occasions that require customization. Summary of the Invention
[0005] Aiming at the problems raised in the above background art, the purpose of the present invention is to provide a mortise and tenon jointed modular 3D orthotic insole.
[0006] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows:
[0007] The mortise and tenon jointed modular 3D orthotic insole includes a base, which is divided into a toe section, a foot section, and a heel section. A plurality of pin blocks are installed at the bottom of the toe section, and a plurality of pin posts are evenly installed at the bottoms of the foot section and the heel section;
[0008] A soft cushion layer is installed on the top of the base;
[0009] The toe section is matched with a toe plate through the latch block, the toe plate has a shape that matches the toe section, and the toe plate is provided with latch grooves whose quantity and specifications match the latch block;
[0010] The foot plate section is matched with a first foot plate and a second foot plate through the latch column, the first foot plate is provided with a first latch hole, the second foot plate is provided with a second latch hole, the quantity and specification of the first latch hole and the second latch hole match the latch column, the first foot plate is provided with a mortise, the second foot plate is provided with a tenon, the tenon block is engaged with the mortise;
[0011] The heel section is matched and mounted with a heel block through the latch column, and the heel block is provided with a third latch hole.
[0012] It is further defined that the cushion layer is made of polyester and fine fibers, and is connected to the base by hot pressing and bonding. With this design, polyester itself has high strength and high elasticity, and the fine fiber weaving further strengthens these characteristics, making the fabric strong and durable, not easy to damage, and can quickly recover to its original state, wrinkle-resistant and iron-free. Polyester is one of the most heat-resistant fabrics among synthetic fibers, and the fine fiber weaving does not affect its heat resistance, so the fabric can withstand high-temperature ironing and is not easy to deform. Polyester fabrics have good plasticity, and the fine fiber weaving makes it easier for the fabric to maintain its shape, such as the pleats of a pleated skirt can be maintained for a long time. Polyester fabrics have good light resistance, and the fine fiber weaving will not reduce its sun resistance. At the same time, polyester fabrics have good resistance to various chemicals and are not easily damaged by acids and alkalis.
[0013] It is further defined that the latch block is arc-shaped and has at least three sections. Such a design ensures the stability of the connection and the matching support strength after the connection.
[0014] It is further defined that the second foot plate is connected to the side bottom of the foot plate section and its size is one quarter of the foot plate section. Such a design is adapted to the shape of the foot, and by adding different numbers of second foot plates, different strengths of support effects can be achieved, thereby achieving the purpose of correction.
[0015] It is further specified that the mortise and tenon is a dovetail groove, and such a design has a good bite effect.
[0016] It is further specified that the base, the toe plate, the first foot plate, the second foot plate and the heel block are all made of EVA material. With this design, the EVA material is light, soft, elastic, and has good cushioning performance. It can effectively absorb the impact of the ground on the feet when walking or running, and reduce foot fatigue and the risk of sports injuries. The softness and elasticity of the EVA insole provide the wearer with ultimate comfort, and it is suitable for daily walking, running, fitness and other lightweight sports scenes. The cost of EVA material is relatively low, so that the insole can maintain its performance while being more affordable to meet the needs of mass consumption.
[0017] It is further defined that the latch post is interference matched with the first latch hole, the second latch hole and the third latch hole. Such a design makes it difficult to disengage after direct plugging, thereby ensuring the connection strength.
[0018] It is further defined that the heel section is concave in shape. Such a design covers the periphery of the heel, plays a protective role, and facilitates correction.
[0019] It is further specified that the toe plate, the first foot plate, the second foot plate and the heel plate are all produced by 3D printing. This design not only makes the discharge fast and convenient, but also makes the size control simple and accurate, and has strong adaptability.
[0020] The beneficial effects of the present invention are as follows:
[0021] The present invention can use the latch column to correspondingly install the toe plate, the first foot plate, the second foot plate or the heel plate to change the thickness of the corresponding position, thereby achieving the purpose of correcting the corresponding position of the user;
[0022] The present invention can achieve further changes in thickness at corresponding positions by using latch columns to install different numbers of toe plates, first foot plates, second foot plates or heel plates, thereby achieving the purpose of increasing comfort in use;
[0023] The present invention divides the base into three sections, and there are four corresponding toe plates, first foot plates, second foot plates or heel plates with adjustable thickness, so that four sections of positions can be adjusted, thereby achieving correction effects at different positions, and having a wide range of applications;
[0024] The elements of the present invention can be directly produced by 3D printing. 3D printing technology can quickly transform designs into entities, shorten product development cycles, and facilitate rapid testing and verification. 3D printing can easily achieve various complex geometric shapes and is suitable for aerospace, medical equipment and other fields. 3D printing is additive manufacturing, which only uses required materials, reduces waste generation, reduces production costs, and is beneficial to environmental protection. 3D printing can design parts that require multi-step processing and assembly into an integrated structure, simplify the assembly process, and improve product performance.
