Patent granted for soles with interconnected soft and stiff sub-cells
A recently granted patent (Publication Number: US11992084B2) discloses a unique sole design for footwear, featuring a three-dimensional mesh structure composed of interconnected anisotropic unit cells. Each unit cell consists of a combination of soft and stiff sub-cells, with different isotropic lattice structures. The arrangement of these sub-cells within each unit cell creates an anisotropic lattice shear modulus, with varying moduli measured in different directions. The mechanically anisotropic region of the sole is designed to deform forward under a vertical load, providing enhanced performance and comfort for the wearer.
Furthermore, the patent details the specific configurations of the sub-cells within each unit cell, including the distribution of soft and stiff sub-cells in different quadrants. The lattice compressive modulus and displacement range of the mechanically anisotropic region are also specified, ensuring optimal functionality of the sole. The innovative design aims to improve the overall performance and durability of footwear, offering a unique combination of comfort, support, and deformation characteristics that cater to the needs of users in various activities and environments.
