Segmented Woven Cloth for Footwear Breathability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional woven cloth for shoes lacks breathability and extensibility, leading to discomfort and difficulty in quick wear-on or take-off during exercises due to tightly woven threads.
Innovation Solution
The woven cloth features a combination of longitudinal and lateral threads, with non-woven sections providing greater span than woven sections, allowing for enhanced stretchability and flexibility, and interwoven knots for balanced support and ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If threads are woven tightly to prevent deformation, then structural strength is improved, but breathability deteriorates
Solution Approach 1:
The cloth is divided into woven sections (for structural strength) and non-woven sections (for breathability), with the non-woven section spanning greater distances between lateralwise threads to create larger gaps for ventilation while woven sections provide support at key locations
Solution Approach 2:
Different sections of the cloth have different properties: woven sections provide strength and support where needed, while non-woven sections provide breathability and flexibility in other areas, allowing each part to optimize its function
2Strength
If threads are woven tightly to prevent deformation, then structural strength is improved, but extensibility deteriorates
Solution Approach 1:
The cloth is segmented into woven sections that maintain structural integrity and non-woven sections that provide extensibility, allowing the material to stretch and adapt to foot movement while maintaining overall shape
Solution Approach 2:
The non-woven sections allow dynamic movement and stretching of the cloth to accommodate foot deformation during exercise, while woven sections provide stable anchor points that maintain the overall structure
3Adaptability or versatility
If non-woven section span is increased to improve stretchability, then extensibility is improved, but structural strength deteriorates
Solution Approach 1:
The cloth alternates between non-woven sections (providing stretchability) and woven sections (providing structural strength), creating a pattern where large gaps for ventilation and flexibility are balanced by reinforced woven areas for support
Solution Approach 2:
Structural strength is concentrated in the woven sections where it is most needed for support, while non-woven sections are placed in areas requiring flexibility and stretchability, optimizing the distribution of mechanical properties

AI summary
The woven cloth is formed by a plurality of longitudinal threads and a plurality of lateralwise threads. Each longitudinal thread is woven by a plurality of filaments. Each lateralwise thread is interwoven with and ties the plurality of longitudinal threads. The woven cloth includes a non-woven section and two woven sections which are connected with two ends of the non-woven section. Each woven section includes at least two of the plurality of lateralwise threads which are adjacent to each other. In an extending direction in which the longitudinal threads extend, a span of the non-woven section is greater than a gap span between adjacent two of the lateralwise threads of respective one of the two woven sections.
