Hereinafter, a plurality of embodiments of the present invention will be described with reference to the drawings. For the sake of clarity, many practical details will be explained in the following description. However, it should be understood that these practical details should not be used to limit the present invention. That is to say, in some embodiments of the present invention, these practical details are unnecessary. In addition, in order to simplify the drawings, some conventionally used structures and elements will be shown in a simple schematic manner in the drawings.

Please refer to FIG. 1, which is a schematic flow chart of a method for manufacturing a composite structure of shoe materials according to an embodiment of the present invention.

In one embodiment, the method for manufacturing a shoe material composite structure disclosed in the present invention mainly includes the following steps.

Step S101 is used to establish a database of multiple microstructures with different three-dimensional geometric types.

Step S102 is used to obtain a kinematics characteristic of a user's foot in a one-step cycle.

Step S103 is used to analyze a plurality of motion parameters corresponding to the motion mechanics characteristics.

Shock absorption, rebound, impact attenuation and force are important characteristics of sports shoe materials. Therefore, through the athlete's experience, the relevant sports parameters are obtained by statistical methods; at the same time, engineering data analysis of the materials that can be applied to shoe materials is carried out to further verify the influence of the characteristics of the shoe materials on the athletes. Next, choose a microstructure with the characteristics of shock absorption, rebound, impact attenuation and force to form the composite structure of the shoe material in order to meet the needs of the athletes in various competition conditions. The following is a detailed description of the above steps S101, S102, S103, S104, and S105.

Please refer to Fig. 2, which shows a schematic diagram of the movement mechanics characteristics of a user's foot in a one-step cycle. As shown in Figure 2, the gait cycle can be roughly divided into a stance phase and a swing phase. The stance phase begins with heel contact/initial contact, at which point the foot will begin to perform supination. After that, the body's center of gravity moves forward and enters the mid stance period. At this time, the foot will begin to perform pronation. Then, it will enter the heel-off propulsion period (toe off), and the standing period will end instantly when the toe off the ground. The swing period is from the moment the toe leaves the ground to the next time the heel touches the ground. Our gait is similar when walking and running, but there is no moment when our feet leave the ground at the same time. Injuries are usually caused by the feet being too stiff, insufficiently soft, or due to improper forward rotation.

Refer now to Figures 3 to 5. Figure 3 is a schematic diagram of the skeletal structure 400 of a user's foot; Figure 4 is a schematic diagram of the arch formed on the user's foot; Figure 5 is a schematic diagram of the arch of Figure 4 The area distribution map of the sole of the foot. Roughly speaking, the foot structure is mainly composed of 26 bones, 19 main muscles (including the remaining small muscle groups) and more than one hundred ligaments. Nearly 30 joints are formed by the combination of ligaments and joints. A skeletal structure 400 roughly includes the posterior area, the arch area, and the forefoot area. The posterior area is composed of talus 401 and calcaneus 402. The talus 401 can move freely where it forms a joint with the tibia 403 and the fibula 404. The calcaneus 402 is located below the talus 401 and protrudes back to form the base of the back heel to assist in supporting the body's weight. The arch area is composed of a scaphoid bone 405, a cubic strand 406, three wedge bones 407, and five long and narrow metatarsal bones 408 (midfoot bones). The forefoot area consists of five toes. The big toe, like the thumb, consists of only two phalanges 409, and is mainly used for bearing weight when bearing a weight. The other toes are composed of three phalanges 410, mainly to stabilize the gait, so that the foot is not easy to sprain. And when the foot strength is insufficient, it also provides a grip to keep the foot stable. The feet are responsible for bearing the weight of the whole body and absorbing the reaction force of the ground when walking. The important function of the foot is support and propulsion, so it is very important to train the foot muscles and foot function. Modern people often wear inappropriate shoes, resulting in insufficient foot function or incorrect gait and foot problems.

When supporting the weight of the human body, the first and fifth metatarsal bones 408 (midfoot bones) and the calcaneus 402 are mainly in contact with the ground, and there are three arches between these three bones. They are the medial longitudinal arch 420 (point A-C), the lateral longitudinal arch 430 (point B-C), and the transverse arch 440 (point A-B). The three arches form a triangular structure to maintain the stability of the foot structure. The main functions of the arch of the foot are: (1) to disperse gravity from the ankle joint through the talus 401 forward to the small head of the metatarsal bone 408 (middle foot bone), and then to the calcaneus 402 to ensure the stability of the plantar support when standing upright . (2) When the body jumps or falls from a height to the ground, the elasticity of the arch plays an important role in cushioning shock. (3) When walking, especially when traveling for long distances, the elasticity of the foot arch has a buffering effect on the downward transmission of the body's gravity and the rhythm of the ground rebound force. (4) The arch of the foot can keep the plantar blood vessels and nerves from being compressed.

When the user uses the foot to travel, during the so-called gait cycle, the user will apply different pressures to each bone in the foot at different times. For example, during a typical walking action, when the gait cycle begins, when the user first touches the ground through his heel, pressure is applied to the calcaneus 402. When the user moves his weight forward on his foot, the pressure applied to the calcaneus 402 becomes less and starts to apply pressure to the talus 401, navicular bone, cuboid bone, and cuneiform bone. When the user starts to lift the foot to travel, the pressure applied to the talus 401, the navicular bone, the cuboid bone, and the cuneiform bone becomes less, and starts to apply pressure to the middle segment bone (metatarsal bone 408). When the user travels forward, pressure is applied along the middle bone and the middle bone-phalangeal 410 joint. Finally, when the user starts to lift the toe and ends the contact with the ground, the pressure applied to the middle phalanx-phalangeal 410 joint becomes smaller, and pressure is applied to the phalanx 410. Finally, in order to lift the toe, the user applies pressure to the phalanges 410 to travel forward. The user then lifts the foot to swing, and places the foot in a forward position relative to where he lifted the foot. When the user puts the foot down again, his heel touches the ground and starts a new gait cycle.

In the gait cycle of different messengers, there may be different ways of advancing, so different parts of the foot may be subjected to different amounts of pressure over time. In addition, the pressure applied to different parts of the foot may also vary with different users. Some users put more pressure on the middle part of the foot than on the lateral part during the gait cycle. And different users have different parts that touch the ground. The shoe is planned to provide support and protection to the user's foot during the gait cycle, so as to provide comfort and assist travel. Based on the difference in foot structure between different users, their respective applicable shoes are different.

Please refer to Figure 6 and Figure 7. Figure 6 is a schematic diagram showing the gravity changes of the heel during the gait cycle; Figure 7 is a schematic diagram showing the gravity changes of the forefoot during the gait cycle. As mentioned above, the gait cycle can be roughly divided into a stance period and a swing period. The stance period starts when the heel touches the ground and ends when the toe off the ground (toe off). Therefore, when the heel or forefoot touches the ground, different changes in gravity are applied. It can be seen from Fig. 6 and Fig. 7 that the gravity change is a complex process. Therefore, the use of a single material or structure of shoe materials cannot cope with the complex changes of gravity and its reaction force during the gait cycle.

Please refer to Figures 8A-8D, Figure 9, Figure 10A, and Figure 10B. FIG. 8A is a schematic diagram of various microstructures according to embodiments of the present invention; FIG. 8B is a three-dimensional schematic diagram of the first microstructure 110 of FIG. 8A; FIG. 8C is a schematic diagram of the second microstructure of FIG. 8A A three-dimensional schematic diagram of 210; Fig. 8D is a three-dimensional schematic diagram of the third microstructure 310 of Fig. 8A; Fig. 9 is a shoe material formed by a shoe material composite structure formed by the microstructure of Fig. 8A Schematic diagram; Figure 10A is a side view of the shoe material composite structure of Figure 9; Figure 10B is a three-dimensional enlarged schematic diagram of the shoe material composite structure of Figure 9; the shoe material composite structure of the present invention, It is composed of at least two microstructures. The greater the number of microstructures, the more complex changes can be obtained, and the more complex changes can be obtained in the same shoe material, corresponding to the complex motion mechanics characteristics in the gait cycle. In Figures 8A to 8D, the composite structure of shoe material is shown by stacking the first microstructure 110, the second microstructure 210, and the third microstructure 310. It should be understood that the first microstructure 110, the second microstructure 210, and the third microstructure 310 can also surround each other to form another composite shoe material structure, which will be described in detail later.

In Figures 8A to 8D, the first microstructure 110 is composed of a first mesh 111 and includes a first mesh density; the second microstructure 210 is composed of a second mesh 211 and includes a second mesh density The third microstructure 310 is composed of a third grid 311 and includes a third mesh density. The first mesh density, the second mesh The density and the third mesh density are different from each other. The rigidity and elasticity of the first microstructure 110, the second microstructure 210, and the third microstructure 310 all vary with the gait cycle of the user's foot. The first grid 111, the second grid 211, and the third grid 311 are each formed by periodically connecting and combining the first grid unit 111a, the second grid unit 211a, and the third grid unit 311a. The first mesh unit 111a, the second mesh unit 211a, and the third mesh unit 311a each include a plurality of arms L and a plurality of vertices S formed by each of these arms L being connected in pairs, and thus these arms The mesh formed by the closure of L and apex S. The difference between the first mesh unit 111a, the second mesh unit 211a, and the third mesh unit 311a is that the length and shape of the respective arms L and the gaps formed by the vertices S are different, thereby making the first The rigidity and elasticity of the microstructure 110, the second microstructure 210, and the third microstructure 310 are different from each other. For example, the arm L of the second grid unit 211a is arc-shaped. Therefore, in one embodiment, the first microstructure 110 has the highest rigidity and provides a supporting effect; the second microstructure 210 has lower rigidity than the first microstructure 110 and provides a cushioning effect, while the third microstructure 310 has lower rigidity. With the effect of absorbing energy.

Figures 9, 10A, and 10B show different shoe material composite structures formed by combining the first microstructure 110 and the second microstructure 210. Generally, it is a part of a complete shoe. The shoe material composite structure composed of the first microstructure 110 and the second microstructure 210 can be combined with a sole plate (not shown). The combination method can be any 3D printing molding method, and there is no particular limitation. After the composite structure of the shoe material is combined with the sole plate, it can be applied to part of the structure of the shoe, such as the midsole, the insole or the outsole of the shoe, in order to obtain the corresponding function.

Please refer to Figure 11 and Figure 12. Figure 11 is a schematic diagram of the force distribution area of the user's foot; Figure 12 is a schematic diagram of the shoe material composite structure formed by the microstructure of Figure 8A corresponding to the force area of the foot. In Figure 11, the force-receiving area of the foot roughly corresponds to the area composed of the microstructure of the shoe material, so as to achieve various supporting, cushioning or shock-absorbing effects in response to the various parts of the user's foot. For example, the regions 301, 302, 303, 304, 305, and 306 each include a first microstructure 110 and a second microstructure 210 composed of a first grid 111, a second grid 211, and a third grid 311 And a different combination of the third microstructure 310. Because the shape and structure of the feet of different users are different, and during different stages of the gait cycle, different areas of the feet are also subjected to different amounts of pressure, so the first grid 111, the second grid 211, and the first grid 111 The three-dimensional geometry of the three grids 311 is also different, so that the same shoe material can provide appropriate support and protection for the feet of different users.

Please refer to Figure 13 and Figure 14. Figure 13 is a schematic diagram showing the variation of rigidity of different microstructures with diameter; Figure 14 is a schematic diagram showing the variation of elasticity of different microstructures with diameter. The reason why the microstructure of the present invention can provide corresponding changes in elasticity and rigidity in response to the cyclical changes of the user's foot is based on the fact that the microstructure can change with the applied force. In Figs. 13 and 14, with the different diameters of the mesh units constituting the microstructure, it can be seen that the rigidity and elasticity also change. Moreover, for microstructures with different three-dimensional geometric shapes, the rigidity or elasticity varies with the diameter. In this way, it is possible to select suitable microstructures to form the composite structure of the shoe material in response to the different mechanical characteristics of the user's foot during the gait cycle, so as to meet the needs of different conditions.

Please refer to Figure 15 to Figure 17. Figure 15 is a schematic diagram showing the maximum displacement of the first microstructure 110 with diameter; Figure 16 is a schematic diagram showing the maximum displacement of the second microstructure 210 with diameter; Figure 17 is a schematic diagram of the third microstructure Schematic diagram of the maximum displacement of 310 as a function of diameter. For the first microstructure 110, the second microstructure 210, and the third microstructure 310 mentioned above, the displacement of the respective microstructures when the force is applied also varies with the diameter. With the difference of the respective three-dimensional geometric types, the maximum displacement of the first microstructure 110, the second microstructure 210, and the third microstructure 310 varies with the diameter. The larger the maximum displacement, the smaller the volume, resulting in greater rigidity (ie hardening) of the overall structure. Therefore, if the cell size of the microstructure is smaller, the mesh density is denser and the support is better. If the diameter of the microstructure is larger, the amount of deformation is smaller and the support is better, but the energy absorption effect will be reduced. . Furthermore, through the different three-dimensional geometric forms of different microstructures, the rigidity changes are also different. Therefore, when using different microstructures to form a composite structure of shoe materials, it can automatically respond to the changes in the gait cycle of the user's foot. Rigidity changes.

The above system uses different elastic modulus and energy absorption to show the phenomenon of the reaction force transmission from the movement of energy from the body, through the foot to the shoe material, and then to the ground. When force is transmitted, each layer of microstructure absorbs the energy impact of movement due to force penetration through the microstructure, and due to structural deformation, it is densified within the elastic load range (that is, the greater the displacement, the smaller the volume). Therefore, the rigidity of the structure changes (the greater the displacement, the stronger the rigidity).

Please refer to Figure 18 and Figure 19. Figure 18 is a schematic diagram showing the maximum displacement of the composite structure of the shoe material combined with the same three-dimensional geometric shape into a double-layer shoe material composite structure as a function of the diameter. Figure 19 is a schematic diagram showing the maximum displacement of the composite structure of a two-layer shoe material with a combination of different three-dimensional geometrical microstructures. From Figure 18, it can be seen that if the microstructures with the same three-dimensional geometry are stacked to form a two-layer composite structure of shoe materials, the characteristics of the composite structure seem to be similar to those of the individual microstructures. As shown in Figure 19, when microstructures with different three-dimensional geometric shapes are stacked to form a two-layer composite structure of shoe materials, the characteristic performance changes significantly. From the results of Fig. 18 and Fig. 19, it can be shown that the combination of microstructures with different three-dimensional geometric types can achieve wider applicability. In other words, a shoe material composite structure with two types of microstructures can have different displacements under the same diameter, so that different rigidity and elastic changes can be obtained.

Please refer to Figure 20 to Figure 22 now. Fig. 20 is a schematic diagram showing another shoe material composite structure 500 formed by the microstructure of Fig. 8A; Fig. 21 is a partial enlarged schematic diagram showing the shoe material composite structure 500 in Fig. 20; and Fig. 22 A three-dimensional view of the sole formed by the shoe material composite structure 500 in FIG. 20 is shown. In Figure 20, a plurality of microstructures are not only stacked on each other, but also surrounded by each other to form a complex three-dimensional structure. In Figure 21, the mesh density of the grids that make up the microstructures is different. The mesh density of the surrounding microstructure is denser than the mesh density of the surrounding microstructure. Therefore, the density of the outside is dense and the density of the inside is sparse, and the density is about 1.2 to 1.5 times worse. In this way, the outer density provides support and the inner sparseness provides comfort. From Figure 21, in addition to the difference in the mesh density of the microstructure, the thickness of the arm L of the microstructure is also different. Similarly, the thicker arm L provides better support, and the thinner arm L provides comfort. In Figure 22, the shoe material formed by the above structure is shown. When the user wears, the outer side of the shoe material provides good support, and the inner side of the shoe material that contacts the sole of the user's foot provides good comfort.

The shoe material composite structure of Figures 9, 10A, and 10B of the present invention and the shoe material composite structure 500 of Figures 20, 21, and 22 of the present invention have been proven to be able to control rigidity and elasticity, and can provide a (rigidity and elasticity) ), provides another type (rigidity and elasticity) during dynamic travel, and is consistent with the adjustment of the force given by the body to the midsole of the shoe during exercise.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of the attached patent application.
