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 are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not necessary. In addition, some of the conventional structures and elements are shown in the drawings in a simplified schematic manner in order to simplify the drawings.

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

In one embodiment, the method for manufacturing a shoe composite structure disclosed by the present invention mainly comprises the following steps.

Step S101 is used to create a database of a plurality of microstructures having different solid geometry patterns.

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

Step S103 is used to analyze a plurality of motion parameters required to correspond to the kinematics of the motion.

Step S104 is used to select a suitable plurality of microstructures from the database according to the motion parameters.

Step S105 is used to form a shoe composite structure in combination with the microstructures.

Shock absorption, rebound, impact attenuation and force are important characteristics of sports shoes. Therefore, through the experience of athletes, the relevant motion parameters are obtained by statistical methods. At the same time, engineering data analysis can be applied to the materials that can be applied to the shoe materials to further verify the influence of the shoe material characteristics on the athletes. In the continuation, the composite structure of the shoe material with the characteristics of shock absorption, rebound, impact attenuation and force is selected to meet the needs of the athletes in various competition situations. The above steps S101, S102, S103, S104, and S105 will be described in detail below.

Please refer to FIG. 2, which is a schematic diagram showing the kinematics of a user's foot in a one-step period. As shown in Fig. 2, the gait cycle can be roughly classified into a stance phase and a swing phase. The standing period starts from the heel contact/initial contact, at which point the foot will begin to perform a supination. After the continuation, the center of gravity moves forward and enters the full stance. At this point, the foot will begin the pronation. Then, it will enter the propulsion of the heel from the ground, and the standing period ends when the toe off the ground. The swing period is from the moment the toes go to the ground until the next heel strikes the ground. The gait we walked and ran was similar, but there was no moment when we walked away from the ground. This usually causes injury because the foot is too stiff, not soft enough, or due to improper spin.

Reference is now made to Figures 3 through 5. Figure 3 is a schematic view of a bone structure 400 of a user's foot; Figure 4 is a schematic view of the arch portion formed by the user's foot; Figure 5 is a diagram showing the arch portion of Figure 4 The area map of the soles of the feet. In general, the foot structure consists mainly of 26 bones, 19 main muscles (including the remaining small muscle groups) and more than one hundred ligaments. A combination of ligaments and joints consists of nearly 30 joints. A skeletal construct 400 generally includes the posterior region, the arch region, and the anterior region. The posterior region consists of talus 401 and calcaneus 402. The talus 401 is free to move where it forms a joint with the tibia 403 and the tibia 404. The calcaneus 402 is located below the talus 401 and protrudes to the posterior side to form the base of the heel to assist in supporting the weight of the body. The arch area consists of a scaphoid 405, a cubic strand 406, three wedge-shaped bones 407, and five narrow tibias 408 (middle foot bones). The forefoot area consists of five toes. The big toe, like the thumb, consists of only two pieces of phalanges 409, mainly for weight bearing when loaded. The other toes are composed of three phalanges 410, mainly in a stable gait, so that the feet are not easily sprained. And when the strength of the foot is insufficient, it also provides a grip to keep the foot in a stable position. The foot system is responsible for bearing the weight of the whole body and absorbing the reaction of the ground when walking. The important functions of the foot are support and advancement. Therefore, it is very important to train the muscles and feet of the foot. Modern people often wear inadequate shoes, resulting in insufficient foot function or incorrect gait to form a foot problem.

When supporting the weight of the human body, the first contact with the ground is the first and fifth metatarsal 408 (middle foot bone) and the calcaneus 402, and there are three arches between the three bones. They are the medial longitudinal arch 420 (point A-C), the outer longitudinal arch 430 (point B-C), and the transverse arch 440 (point A-B), respectively. The three bows form a triangular structure that maintains the stability of the foot structure. The main functions of the arch are: (1) to spread gravity from the ankle joint through the talus 401 to the humerus 408 (middle foot bone) head, and back to the calcane 402 to ensure the stability of the plantar support when standing upright. . (2) When the body jumps or falls from a height, the arch elasticity plays an important role of buffering and oscillating. (3) During walking, especially during long journeys, the elasticity of the arch has a cushioning effect on the gravity of the body and the rhythm between the ground rebound forces. (4) The arch can keep the blood vessels and nerves of the plantar from oppression.

When the user is using the foot to travel, during the so-called gait cycle, the user will apply different pressures to the various bones in the foot at different times. For example, during a typical walking motion, at the beginning of the gait cycle, the user first applies pressure to the calcaneus 402 as he approaches the ground through his heel. As the user moves their weight forward on the foot, pressure is applied to the calcaneus 402 and pressure is applied to the talus 401, the scaphoid, the tibia, and the cuneiform bone. As the user begins to lift the foot, pressure is applied to the talus 401, the scaphoid, the tibia, and the cuneiform bone, and pressure is applied to the midsole (the tibia 408). As the user travels forward, pressure is applied along the mid-segment bone and the mid-node-toe bone 410 joint. Finally, when the user starts lifting the toes and ends the contact with the ground, the pressure applied to the joint of the middle bone-toe bone 410 becomes small, and pressure is applied to the phalanx 410. Finally, in order to lift the toes, the user applies pressure to the phalanges 410 to travel forward. The user then lifts the foot to swing and places the foot forward relative to where he lifted the foot. When the user puts the foot down again, his heel touches the ground and begins a new gait cycle.

In different gait cycles 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 apply more pressure to the middle portion of the foot than to the lateral portion during the gait cycle. 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 to provide comfort and assist in travel. Based on the difference in the structure of the feet between different users, the respective applicable shoes are different.

Please refer to Figure 6 and Figure 7. Figure 6 is a schematic diagram showing the change in gravity of the heel in the gait cycle; Figure 7 is a schematic diagram showing the change in gravity of the anterior portion in the gait cycle. As described above in the gait cycle, it can be roughly divided into a standing period and a swing period, and the standing period starts from the heel touch and ends at the toe off moment. Therefore, when the heel or the forefoot touches the ground, different gravity changes are applied to each. It can be seen from Fig. 6 and Fig. 7 that the change of gravity is a complicated process, so the use of a single material or a structure of the shoe material cannot cope with the complicated change of the gravity and the reaction force in the gait cycle.

Please refer to Figures 8A-8D, 9th, 10A and 10B. 8A is a schematic view showing a plurality of microstructures according to an embodiment of the present invention; FIG. 8B is a perspective view showing a first microstructure 110 of FIG. 8A; and FIG. 8C is a second microstructure of FIG. 8A; FIG. 8D is a perspective view showing a third microstructure 310 of FIG. 8A; and FIG. 9 is a shoe material formed by a composite material of a shoe material composed of the microstructure of FIG. 8A. FIG. 10A is a side view showing the composite structure of the shoe material according to FIG. 9; FIG. 10B is a perspective enlarged view showing the composite structure of the shoe material according to FIG. 9; It consists of at least two microstructures. The greater the number of microstructures, the more complex changes can be achieved, and in the same shoe material, corresponding to the complex kinematics of the gait cycle. In the 8A-8D drawings, a shoe composite structure in which the first microstructure 110, the second microstructure 210, and the third microstructure 310 are stacked is shown. It should be noted that the first microstructure 110, the second microstructure 210, and the third microstructure 310 may also surround each other to form another shoe composite structure, which will be described in detail later.

In FIGS. 8A-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 mesh 311 and includes a third mesh density. The first mesh density, the second mesh density, and the third mesh density are each different. The rigidity and elasticity of the first microstructures 110, the second microstructures 210, and the third microstructures 310 each vary with the dynamic period of the user's foot. The first mesh 111, the second mesh 211, and the third mesh 311 are each periodically connected and combined by the first mesh unit 111a, the second mesh unit 211a, and the third mesh 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 the two arms of the arms L, and thus the arms L and the apex S close the formed mesh. The difference between the first mesh unit 111a, the second mesh unit 211a, and the third mesh unit 311a is that the lengths, shapes, and gaps formed by the respective vertices S of the respective arms L are different, thereby making the first The rigidity and elasticity of the microstructures 110, the second microstructures 210, and the third microstructures 310 are different. For example, the arm L of the second mesh unit 211a is curved. Thereby, in an embodiment, the first microstructure 110 has the highest rigidity and provides a supporting effect; the second microstructure 210 is lower in rigidity than the first microstructure 110, and provides a buffering effect, and the third microstructure 310 has a lower rigidity. With energy absorption effect.

FIGS. 9 , 10A, and 10B illustrate different shoe composite structures in which the first microstructure 110 and the second microstructure 210 are combined. Typically, the shoe composite structure combined with the first microstructure 110 and the second microstructure 210 can be combined with a sole plate (not shown) for forming a complete shoe. The bonding method can be any 3D printing molding method, and is not particularly limited. After the shoe composite structure is combined with the sole plate, it can be applied to a part of the structure of the shoe midsole, the insole or the outsole in order to obtain a corresponding function.

Please refer to Figure 11 and Figure 12 for details. Fig. 11 is a schematic view showing a distribution area of a user's foot force; and Fig. 12 is a schematic view showing a force-receiving area of the shoe composite structure composed of the microstructure of Fig. 8A corresponding to the foot. In Fig. 11, the force receiving area of the foot substantially corresponds to the area of the microstructure of the shoe material to achieve various supporting, cushioning or shock absorbing effects in response to portions of the user's foot. For example, the regions 301, 302, 303, 304, 305, 306 each include a first microstructure 110 and a second microstructure 210 composed of a first mesh 111, a second mesh 211, and a third mesh 311. And different combinations of the third microstructures 310. Because the shape and structure of the different user's feet are different, and during different stages of the gait cycle, different amounts of pressure are also applied in different regions of the foot, so the first mesh 111, the second mesh 211, and the first The three meshes 311 are also different in the three-dimensional geometry, so that the same shoe material can provide suitable support and protection for different user feet.

Please refer to Figure 13 and Figure 14 for details. Figure 13 is a schematic diagram showing the variation of the stiffness of different microstructures with diameter; Figure 14 is a schematic diagram showing the variation of the elasticity of different microstructures with diameter. The microstructure of the present invention is capable of providing a corresponding change in elasticity and rigidity in response to changes in the gait cycle of the user's foot, based on which the microstructure can vary with force. In Fig. 13 and Fig. 14, as the diameter of the grid unit constituting the microstructure is different, it can be seen that the rigidity and elasticity also change. Moreover, for microstructures with different solid geometry, the stiffness or elasticity varies with diameter. In this way, according to different mechanical properties exhibited by the user's foot in the gait cycle, a suitable microstructure can be selected to form a composite structure of the shoe material to meet different conditions.

Please refer to Figures 15 to 17 now. Figure 15 is a schematic diagram showing the maximum displacement of the first microstructure 110 as a function of diameter; Figure 16 is a schematic diagram showing the maximum displacement of the second microstructure 210 as a function of diameter; and Figure 17 is a third microstructure. Schematic diagram of the maximum displacement of 310 as a function of diameter. The displacements of the first microstructures 110, the second microstructures 210, and the third microstructures 310 as described above, which are generated when the respective microstructures are subjected to the force, also vary with the diameter. The maximum displacement of the first microstructure 110, the second microstructure 210, and the third microstructure 310 varies with diameter as a function of the respective three-dimensional geometry. The larger the maximum displacement, the smaller the volume, resulting in the rigidity of the overall structure becoming larger (ie, hardening). Therefore, if the size of the mesh unit of the microstructure is smaller, the density of the mesh is denser and the support is better. If the diameter of the microstructure is thicker, the smaller the deformation, the better the support, but the energy absorption effect will be reduced. . Furthermore, the variation of the stiffness is different through the different solid geometry of different microstructures. Therefore, when the composite structure of the shoe material is composed of different microstructures, the gait cycle of the user's foot can be changed differently. Rigidity changes.

The above-mentioned system utilizes different elastic modulus and absorbed energy, and exhibits a reaction phenomenon that the movement behavior transmits energy from the body, through the foot to the shoe material, and then to the ground. When each layer of microstructure is transmitted by force, the penetration of the force absorbs the energy impact during the movement due to the microstructure, and the densification occurs in the elastic load range due to the structural deformation (ie, the displacement is larger and the volume is smaller). Therefore, the rigidity of the structure changes (the larger the displacement, the stronger the rigidity).

Please refer to Figure 18 and Figure 19 for details. Figure 18 is a schematic diagram showing the maximum displacement amount as a function of diameter of a composite material structure in which the microstructure of the same three-dimensional geometry is combined. Fig. 19 is a schematic diagram showing the maximum displacement amount as a function of diameter of a composite structure of a shoe material in which the microstructures of different three-dimensional geometric forms are combined. From Fig. 18, it can be seen that if a double-layered shoe composite structure is formed by stacking microstructures having the same solid geometry, the characteristics appear to be indistinguishable from the individual microstructures. From Fig. 19, when the microstructures with different three-dimensional geometrical forms are stacked to form a double-layered shoe composite structure, the characteristic performance is significantly changed. From the results of Figs. 18 and 19, it can be explained that the combination of microstructures having different solid geometry can be used to obtain wider applicability. In other words, a shoe composite structure having two microstructures can have different displacements at the same diameter, so that different stiffness and elastic changes can be obtained.

Please refer to Figures 20 to 22 now. 20 is a schematic view showing another shoe composite structure 500 composed of the microstructure of FIG. 8A; FIG. 21 is a partially enlarged schematic view showing the shoe composite structure 500 of FIG. 20; A perspective view of a sole formed by the shoe composite structure 500 in FIG. 20 is illustrated. In Fig. 20, a plurality of microstructures are surrounded by each other and are surrounded by each other to form a complicated three-dimensional structure. In Fig. 21, the mesh density of the mesh constituting the microstructure is different. The microstructure surrounding the outer structure is denser than the density of the microstructured mesh surrounded by the inner structure, so that the outer denseness is formed, and the density is about 1.2 to 1.5 times. Thereby, the outer seal provides support and the inner sparse provides comfort. From Fig. 21, in addition to the difference in 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 Fig. 22, a shoe material formed by the above structure is shown. When the user wears, the outer side of the shoe material provides good support, while 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 Figs. 9, 10A, and 10B of the present invention and the shoe material composite structure 500 of Figs. 20, 21, and 22 have been proven to be capable of regulating rigidity and elasticity, and can provide a kind of rigidity and elasticity when standing still. ), providing another (rigidity and elasticity) when moving dynamically, and conforming to the force adjustment of the body to the midsole of the shoe during the movement.

While the invention has been described above by way of example, the invention is not intended to be limited thereby, the scope of the invention is defined by the scope of the appended claims.
