3D Woven Textile with Meandering Braids for Variable Mesh
Solution Overview
Problem
Conventional woven textiles are limited by their uniform thickness, air-permeability, and structural strength, making them time-consuming to produce and difficult to customize for specific functions, such as shoe uppers, which require varying mesh dimensions and elasticity.
Innovation Solution
A three-dimensional woven textile design featuring independent upper and lower layers with meandering braids and binding threads, creating meshes of different dimensions and elastic blocks, enhancing thickness, air-permeability, and elasticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If the manufacturer thickens the woven thread, then the thickness of the woven textile is increased, but the textile becomes too heavy or has poor air-permeability
Solution Approach 1:
The patent transitions from a traditional single-layer two-dimensional woven structure to a three-dimensional multi-layer structure where upper and lower layers are connected by binding threads. This dimensional change allows the textile to achieve increased thickness without simply thickening individual threads, thereby maintaining light weight and good air-permeability while providing the desired thickness.
Solution Approach 2:
The invention creates a porous three-dimensional structure with interconnected void spaces between the upper and lower layers. This porous architecture enables air to permeate through the textile effectively while maintaining thickness, avoiding the harm of poor air-permeability that would result from using thicker traditional woven threads.
2Volume of stationary object
If the manufacturer weaves the woven threads for multiple times, then the thickness of the woven textile is increased, but it is labor-consuming and time-consuming and has poor air-permeability
Solution Approach 1:
The patent divides the woven textile into separate upper and lower layers that are woven independently and then connected by binding threads. This segmentation allows each layer to be woven separately and efficiently, avoiding the time-consuming process of multiple weaving passes, while still achieving the desired thickness through the three-dimensional structure.
Solution Approach 2:
Instead of increasing thickness through multiple weaving operations in the same plane, the invention uses a three-dimensional multi-layer structure. This dimensional approach achieves thickness in a single weaving process rather than requiring multiple time-consuming weaving passes.
3Area of moving object
If the manufacturer uses stitch skipping to make the meshes greater, then the mesh dimensions are increased, but it is difficult to manufacture and the structural strength decreases
Solution Approach 1:
The patent segments the woven structure into upper and lower layers with binding threads connecting them. This segmentation allows for controlled mesh dimensions through the design of the binding thread pattern rather than requiring difficult stitch skipping techniques, making the manufacturing process easier while maintaining structural integrity.
Solution Approach 2:
The invention applies different weaving patterns and binding thread configurations to different regions of the textile. This allows mesh dimensions to be customized in specific local areas without compromising the overall structural strength, as each region can be optimized independently through appropriate binding thread placement.
4Device complexity
If the woven textile is woven continuously with single one thread, then the manufacturing process is simple, but it is time-consuming and once there was a loose thread, the woven textile would be torn apart completely
Solution Approach 1:
The patent divides the continuous single-thread weaving into separate upper and lower layers that are woven independently and then connected by binding threads. This segmentation creates multiple load paths, so that if one thread becomes loose, the structural integrity is maintained through the alternative pathways provided by the multi-layer structure and binding threads.
Solution Approach 2:
The invention creates a composite structure combining upper layer threads, lower layer threads, and binding threads into a unified three-dimensional woven textile. This composite architecture enhances reliability by distributing mechanical loads across multiple independent thread systems, preventing complete failure from a single loose thread while maintaining manufacturing simplicity.
5Device complexity
If two surfaces of the woven textile are made of the same material, then the manufacturing process is simple, but the function of the woven textile is limited
Solution Approach 1:
The patent segments the woven textile into distinct upper and lower layers that can be made from different materials. This segmentation enables each layer to be optimized for specific functions (e.g., upper layer for aesthetics, lower layer for durability), greatly enhancing functional versatility while the binding thread connection maintains manufacturing simplicity.
Solution Approach 2:
The invention allows different materials, colors, and weaving structures to be applied to different regions and layers of the textile. This local quality approach enables customization of specific areas for different functions (e.g., different mesh sizes for different body parts) while maintaining overall manufacturing efficiency through modular construction.

AI summary
A woven textile is provided, including at least two blocks connected with each other. Each of the two blocks has an upper layer and a lower layer which are woven and fixed by a binding thread, and the upper layer and the lower layer are respectively composed of woven braids which extend meanderingly. The textile braid of the upper layer and the textile braid of the lower layer define a plurality of meshes, and the textile braids of the two blocks have different diameters so that the meshes on the two blocks have different dimensions.
