Textile Garment Layer With Variable Elastomer Adhesive Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clothing technologies face challenges in achieving both high supporting or holding forces and comfort, as current adhesive applications either compromise elasticity or limit wearing comfort due to the use of thermoplastics with low elasticity.
Innovation Solution
The use of an elastomeric adhesive applied in a pattern of intersecting lines or stripes on a textile fabric layer, with varying adhesive density along the length and width, allowing for adjustable supporting forces without restricting the fabric's elasticity, combined with optional flocking for enhanced comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If thermoplastic adhesive is applied to fabric layer, then supporting force is improved, but elasticity and wearing comfort deteriorate
Solution Approach 1:
The patent changes the material parameter from thermoplastic to elastomeric adhesive, which fundamentally alters the elastic properties while maintaining adhesive functionality. This parameter change resolves the contradiction by providing both supporting force and elasticity simultaneously.
Solution Approach 2:
The patent uses composite structures by combining elastomeric adhesive with fabric layers in multi-layer configurations. This composite approach allows the adhesive to provide support while the fabric structure maintains elasticity and comfort.
2Strength
If adhesive density is increased to improve supporting force, then holding force is improved, but elasticity of fabric layer deteriorates
Solution Approach 1:
The patent applies adhesive in specific patterns (dots, lines, or areas) rather than uniformly across the entire fabric. This local application provides supporting force where needed while leaving other areas elastic and comfortable, resolving the contradiction between holding force and fabric elasticity.
Solution Approach 2:
The adhesive is segmented into discrete applications (dots, lines, or patterned areas) rather than continuous coverage. This segmentation allows the fabric to maintain elasticity in non-adhesive areas while still providing sufficient holding force through the adhesive segments.
3Ease of manufacture
If uniform adhesive application is used, then manufacturing simplicity is improved, but functional adaptation of supporting forces deteriorates
Solution Approach 1:
The patent enables dynamic adaptation of adhesive properties through variable density patterns, where the concentration and distribution of adhesive can be adjusted for different functional zones. This allows the same basic application process to produce garments with differentiated supporting forces in different areas.
Solution Approach 2:
The patent implements local quality variations in adhesive density and pattern to provide different levels of support in different garment areas. This allows functional adaptation while maintaining relatively simple manufacturing processes.
