Cut Resistant Gloves With Localized Enhanced Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cut resistant gloves are limited to jersey knit patterns, which restricts the ability to create gloves with varied knit patterns that could enhance specific regions for improved cut resistance and comfort, particularly in high-risk areas like food preparation and touch screen compatibility.
Innovation Solution
A method using a whole garment, computer-controlled slide needle knitting machine to produce cut resistant gloves in multiple knit patterns, such as full jacquard, intarsia, and mesh, incorporating enhanced sections with ultra high molecular weight polyethylene, high tenacity nylon, and liquid crystal polymer for increased cut resistance, and electrically conductive yarns for touch screen compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional jersey knit pattern is used, then manufacturing simplicity is maintained, but cut resistance and comfort in specific regions cannot be enhanced
Solution Approach 1:
The patent applies local quality by using enhanced sections with different knit patterns (mesh, intarsia, full jacquard) in specific high-risk areas such as fingers, thumb, and palm, while maintaining simpler jersey knit in other regions. This allows cut resistance to be enhanced precisely where needed without making the entire glove overly complex
Solution Approach 2:
The glove is segmented into multiple sections (enhanced sections and non-enhanced sections) with different knit patterns and material properties. The enhanced sections targeting high-risk areas use complex patterns like full jacquard and intarsia, while other areas use simpler patterns, allowing the overall design to balance protection with manufacturability
2Strength
If uniform material distribution is used, then manufacturing simplicity is maintained, but specific high-risk areas cannot receive enhanced protection
Solution Approach 1:
Different material compositions are used in different sections of the glove. Enhanced sections in high-risk areas (fingers, thumb, palm) incorporate cut-resistant materials like ultra high molecular weight polyethylene, high tenacity nylon, or liquid crystal polymer, while other areas use standard materials, optimizing both protection and manufacturing
Solution Approach 2:
The patent uses composite materials in enhanced sections, combining cut-resistant fibers (ultra high molecular weight polyethylene, high tenacity nylon, liquid crystal polymer) with base materials to create yarns that provide enhanced cut resistance while maintaining flexibility and comfort in specific regions
3Ease of operation
If standard knit patterns are used, then manufacturing simplicity is maintained, but touch screen compatibility and comfort are reduced
Solution Approach 1:
The patent applies local quality by incorporating electrically conductive yarns in specific enhanced sections that contact the skin (fingertips, palm areas) to enable touch screen operation, while other areas of the glove maintain standard knit patterns for comfort and flexibility
Solution Approach 2:
Electrically conductive yarns are integrated into the enhanced sections as composite materials, combining conductive fibers with knit structure to provide touch screen compatibility in specific areas without requiring the entire glove to have complex conductive patterning

AI summary
A cut resistant glove includes a primary layer and a plurality of enhanced sections having substantially enhanced physical characteristics in relation to the primary layer. The glove includes a palm section, a back hand section, a thumb section and a plurality of finger sections. The enhanced sections can be knitted to the primary layer by a whole garment, computer controlled slide needle knitting machine at positions on the glove where enhanced physical characteristics are desired.
