Shoe Upper Textile Segmentation for Flexible Sole Attachment

Solution Overview

Problem

Conventional shoe uppers with woven designs face reduced flexibility due to the need for filament fixation to the sole, resulting in a bumpy periphery and compromised air permeability.

Innovation Solution

A textile for shoe uppers featuring a warp knitted portion with longitudinal threads that extend to form string portions, allowing for connection to the sole while maintaining flexibility and creating a wearing space, enabling adjustable positioning and fixation without bumpy peripheries.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If all filaments of the shoe upper are fixed to the sole, then the shoe upper is securely attached, but the periphery of the sole becomes bumpy and the flexibility of the shoe upper is reduced

Engineering Contradiction:

Improveattachment strengthVSAvoidflexibility

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The shoe upper is divided into a warp knitted portion and separate string portions. The warp knitted portion remains unfixed to maintain flexibility and smooth periphery, while only the string portions are attached to the sole for secure attachment. This segmentation allows different parts to serve different functions without compromising either flexibility or attachment strength.

Solution Approach 1:

The shoe upper is divided into a warp knitted portion and separate string portions. The warp knitted portion remains unfixed to maintain flexibility and smooth periphery, while only the string portions are attached to the sole for secure attachment. This segmentation allows different parts to serve different functions without compromising either flexibility or attachment strength.

Solution Approach 1:

The shoe upper is divided into a warp knitted portion and separate string portions. The warp knitted portion remains unfixed to maintain flexibility and smooth periphery, while only the string portions are attached to the sole for secure attachment. This segmentation allows different parts to serve different functions without compromising either flexibility or attachment strength.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different parts of the shoe upper have different properties: the warp knitted portion provides air permeability and flexibility, while the string portions provide attachment functionality. This local differentiation allows each part to optimize its specific function without compromising the overall performance.

AI summary

A woven textile for shoe upper includes a main body. The main body includes a woven portion and at least one braiding portion. The main body defines a horizontal direction and a longitudinal direction. The woven portion includes a plurality of longitudinal threads aligned along the horizontal direction. Each of the longitudinal threads extends along the longitudinal direction. Two ends of the woven portion along the longitudinal direction are a first end and a second end. At least one of the longitudinal threads extends and is knotted itself from the first end or the second end of the woven portion away from the woven portion to form the at least one braiding portion.
