Elastic Fabric with Integrated Ventilation and Secure Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional elastic fabrics with breathing holes often fail to provide adequate ventilation in attaching areas, leading to allergic symptoms like itching and eczema due to insufficient cooling and ventilation.
Innovation Solution
The elastic fabric is knitted with rubber threads, first and second elastic wefts, high-tensile nylons, and second wraps, using an S-shaped and inverted S-shaped weaving pattern to create breathing holes and L-shaped patterns for a solid structure with improved ventilation and attachment, incorporating hairy loops for enhanced fixing and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional elastic fabric uses conditional weaving method with breathing areas and attaching areas, then attaching effect is achieved, but ventilation effect is insufficient in attaching areas causing allergic symptoms
Solution Approach 1:
The patent applies local quality by creating different weaving patterns in different areas of the fabric. The attaching areas use the same hook-and-loop structure but incorporate breathing holes within the attaching strips, while breathing areas have larger open spaces. This allows each area to have optimized local properties: attaching areas maintain secure fastening while providing ventilation, and breathing areas provide maximum airflow.
Solution Approach 2:
The fabric is segmented into alternating attaching areas and breathing areas along the length of the elastic piece. Each attaching area contains multiple hairy loops distributed across its width, and each breathing area provides ventilation. This segmentation ensures that ventilation is distributed throughout the entire fabric surface, not just in isolated breathing areas.
2Temperature
If elastic fabric has breathing holes only in breathing areas, then ventilation is provided in those areas, but attaching areas lack cooling and ventilation effect
Solution Approach 1:
The patent implements local quality by varying the density and size of breathing holes between attaching areas and breathing areas. In attaching areas, breathing holes are smaller and more densely distributed to maintain structural integrity while providing ventilation. In breathing areas, larger open spaces provide enhanced airflow. This localized differentiation optimizes both cooling effect and ventilation distribution across the entire fabric.
3Reliability
If conventional weaving method is used with alternating breathing areas and attaching areas, then attaching effect is achieved, but overall ventilation coverage is insufficient
Solution Approach 1:
The fabric structure is segmented into repeating units of attaching areas and breathing areas along the elastic piece. Each attaching area contains multiple hairy loops arranged in rows, and each breathing area provides ventilation. This segmentation pattern ensures that ventilation is distributed throughout the entire fabric surface, maximizing the total ventilation area coverage while maintaining reliable fastening function in attaching areas.
Solution Approach 2:
The patent extends ventilation coverage by incorporating breathing holes not only in the traditional breathing areas but also within the attaching areas themselves. This adds a third dimension to the design by creating multi-layered ventilation: surface-level breathing areas and integrated breathing holes within attaching strips, thereby significantly increasing overall ventilation area coverage without compromising fastening reliability.

AI summary
An elastic fabric made by a plurality of rubber threads, first elastic wefts, second elastic wefts, first wraps, high-tensile nylons and second wraps. The rubber thread, the first elastic weft, the second elastic weft are elastic, and the first elastic weft, and the second elastic weft are knitted across and interlaced with the rubber thread at right angles such that the elastic fabric is configured to be stretched in all directions. The first elastic weft and the second elastic weft are wrapped on at least three rubber threads to form a plurality of breathing holes therebetween, and the first wrap and the second wrap are wrapped along the single rubber thread such that the elastic fabric is configured to have the solid structure and the great ventilation effect simultaneously.
