[0055] The invention also provides a method for making the extremely small curved surface structure;

[0056] Combining with the content of Example 1: the method is based on 3D printing manufacturing, as a preferred technical solution of a 3D printing method of the present invention: various types of 3D printing (or additive manufacturing) technologies can be used;

[0057] 3D printing or "three-dimensional printing" includes various techniques for forming three-dimensional objects by depositing successive layers of material on top of each other;

[0058] Exemplary 3D printing techniques that may be used include, but are not limited to: Fused Filament Fabrication (FFF), Electron Beam Free Forming (EBF), Direct Metal Laser Sintering (DMLS), Electron Beam Melting (EMB), Selective Laser Melting (SLM ), selective heat sintering (SHS), selective laser sintering (SLS), gypsum 3D printing (PP), layered object manufacturing (LOM), stereolithography (SLA), digital light processing (DLP...

Embodiment 3

[0079] The present invention also provides a kind of experimental data;

[0080] The load-bearing of the foot is often considered to be the joint load of the first metatarsophalangeal joint, the fifth metatarsophalangeal joint and the calcaneus. Therefore, the pressure response of the foot is graphically represented, and there are two large pressure-bearing areas of the forefoot and the calcaneus. Stress fractures are the result of bone being subjected to constant impact strain. Therefore, when designing the midsole of the shoe, the above-mentioned 3D printed extremely small curved surface structure is designed correspondingly for the two bearing areas of the forefoot and the backfoot where the plantar pressure is relatively high. When the human body is in motion, under the high impact load condition of the ground's reaction force against the human body, the forefoot and the heel are designed to be compressively deformed, resulting in a relatively short part of the midsole of...

Abstract

The invention relates to the field of shoes, in particular to a minimal curved surface structure, and the structure is formed by filling and / or splicing and / or arraying and / or grading of a plurality of 3D printed units; a unit main body is formed by filling and / or splicing and / or arraying of a plurality of curved surfaces; the minimal curved surface structures are designed on all main stress partsof midsoles through specific materials, shapes, sizes, positions, densities and the like according to different sports events and the foot movement characteristics of people with different movement characteristics, corresponding midsole buffering performance can be provided for different activities, and the individual requirements of different people are met; and moreover, materials are selectedin multiple styles, the design and the structure are in multiple styles, manufacturing is conducted according to different styles, more excellent buffering and resilience performance is achieved, andthe labor-intensive limitation of the traditional shoemaking industry is eliminated.

Description

technical field [0001] The invention relates to the field of shoes, in particular to a very small curved surface structure and a manufacturing method thereof. Background technique [0002] A minimal surface is one whose average curvature is zero. Given an embedded surface, or more generally, an immersed surface (whose boundaries are generally fixed, but not necessarily bounded), define its average curvature as follows: Let P be the surface S On the previous point, consider all curves Ci on S passing through P. Each such Ci has an associated curvature Ki at point P. Among these curvatures Ki, there is at least one maximum value K1 and minimum value K2, and these two curvatures K1 and K2 are called the main curvature of S. [0003] In fact, the coverage of minimal surfaces is wider than that of such minimum-area surfaces. The definition of a minimal surface can also be extended to a constant average curvature surface, that is, a subsurface on a surface composed of points wh...
