Multi-Layered Woven Chin Strap Moisture Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Chin straps in safety helmets have poor moisture management, leading to discomfort and irritation due to sweat trapping against the skin, especially in physical activities or hot and humid environments.
Innovation Solution
A multi-layered woven component with a first side comprising predominantly hydrophobic yarns and a second side comprising predominantly hydrophilic yarns, designed to facilitate moisture transfer from the skin-contacting side to the environment side through differential yarn properties and weaving patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If single component yarn is used for chin straps, then the structure is simple and manufacturing is easy, but moisture management performance is poor
Solution Approach 1:
The patent applies composite materials by combining hydrophobic yarns (first type) and hydrophilic yarns (second type) in a multi-layered woven structure. The hydrophobic outer layer repels sweat while the hydrophilic inner layer absorbs and wicks moisture away from the skin, creating a functional composite that solves the moisture management problem while maintaining structural integrity
Solution Approach 2:
The patent implements local quality by assigning different functional properties to different layers of the woven component. The first side (outer layer) uses predominantly hydrophobic yarns to repel sweat, while the second side (inner layer) uses predominantly hydrophilic yarns to absorb and wick moisture, creating spatially differentiated functionality within a single component
2Object-affected harmful factors
If hydrophobic yarns predominate on the skin-contacting side, then sweat is repelled from the skin, but moisture transfer to the environment requires effective hydrophilic pathways
Solution Approach 1:
The patent applies segmentation by dividing the woven component into distinct functional layers: a first side with predominantly hydrophobic yarns for sweat repulsion, a second side with predominantly hydrophilic yarns for moisture absorption and wicking, and intermediate layers that facilitate moisture transfer. This segmented structure enables each layer to perform its specific function while working together as an integrated system
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively dissipates moisture from the skin surface, keeping the wearer dry and comfortable by transferring sweat from the first side to the second side for evaporation, reducing discomfort and irritation.
Implementation Method 1
The plurality of yarns of the first type comprises hydrophobic yarns or yarns that are less hydrophilic than the plurality of yarns of the second type. The plurality of yarns of the second type comprises hydrophilic yarns or yarns that are less hydrophobic than the plurality of yarns of the first type.
Implementation Method 2
The plurality of yarns of the first type comprises hydrophobic yarns or yarns that are less hydrophilic than the plurality of yarns of the second type
Implementation Method 3
The plurality of yarns of the second type comprises hydrophilic yarns or yarns that are less hydrophobic than the plurality of yarns of the first type
Implementation Method 4
the second side of the multi-layered woven component is adapted to wick and evaporate the moisture received from the first side of the multi-layered woven component to keep the multi-layered woven component dry

AI summary
A multi-layered woven component and method is disclosed. The multi-layered woven component comprising a first side adapted to be in contact with a skin surface of a user, the first side comprising a plurality of yarns of a first type and a plurality of yarns of a second type. The plurality of yarns of the first type in the first side predominates the plurality of yarns of the second type in the first side. Further, a second side opposite to the first side, the second side comprising at least a portion of the plurality of yarns of the second type. Further, the first side of the multi-layered woven component is woven with the second side of the multi-layered woven component to facilitate transfer of moisture from the first side of the multi-layered woven component to the second side of the multi-layered woven component.
