Compression Article Friction Thread Holding Strap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compression articles with elastic textile materials and holding straps suffer from skin irritation and high production complexity due to large silicone nubs or strips that restrict respiratory activity and are costly to produce.
Innovation Solution
A compression article featuring a woven holding strap with friction threads integrated into the fabric, eliminating the need for additional silicone nubs and ensuring minimal skin contact area while maintaining effective slip prevention, with yarns of varying thicknesses and distribution patterns for optimal comfort and pressure adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If silicone nubs or strips are applied to the holding strap inner side, then the holding function (slip prevention) is improved, but the respiratory activity of the skin is restricted and skin irritations occur
Solution Approach 1:
The invention changes the physical parameters of the friction elements by using thin yarns (15-500 dtex) instead of thick silicone nubs, and controls the surface area coverage to be less than 25% (preferably less than 15%) of the strap inner side. This parameter optimization maintains the friction coefficient above 0.4 for effective holding while minimizing skin irritation and preserving respiratory activity.
Solution Approach 2:
The friction threads are selectively positioned at specific locations on the holding strap inner side rather than covering the entire surface. This localized application ensures friction is provided only where needed for holding functionality, while leaving other areas open for skin breathing, thus resolving the contradiction between holding effectiveness and skin comfort.
2Reliability
If silicone nubs or strips are subsequently applied to the holding strap, then the holding function is improved, but the production process becomes more complicated and cost-intensive
Solution Approach 1:
The friction function is merged directly into the holding strap fabric structure by incorporating friction threads during the knitting or weaving process. This integration eliminates the need for separate silicone nub application steps, simplifying the production process while maintaining effective holding functionality through the inherent friction properties of the yarns.
Solution Approach 2:
The holding strap fabric itself provides the friction function through integrated friction threads, eliminating the need for additional silicone components. The fabric structure serves multiple functions simultaneously - structural support, elasticity, and friction-based holding - thereby reducing production complexity and cost.
3Reliability
If large surface area silicone nubs or strips are used on the holding strap, then the holding function is improved, but the respiratory activity of the skin is significantly restricted
Solution Approach 1:
The invention optimizes the surface area parameter of friction elements to be less than 25% (preferably less than 15%) of the holding strap inner side, while maintaining sufficient friction coefficient (>0.4) through appropriate yarn selection. This parameter balance ensures effective holding function while preserving adequate skin respiratory activity.
Solution Approach 2:
Friction threads are positioned at specific localized areas on the holding strap inner side rather than covering the entire surface. This selective placement provides friction where needed for holding while leaving the majority of the skin surface exposed for respiratory activity, resolving the contradiction between holding effectiveness and skin breathing.
