Cut Resistant Glove With Localized Continuous Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Breathable gloves often compromise on cut resistance due to the need for thin materials to maintain dexterity and grip, and existing solutions fail to provide substantial breathability and flexibility on both front and back surfaces while ensuring adequate protection.
Innovation Solution
A work glove design featuring a combination of substantially continuous and non-continuous surfaces, where the finger and thumb ends have a continuous coating for grip and cut resistance, and the palm and back have a non-continuous surface with spaced dots for enhanced protection, using a knitted substrate with foamed coatings and laminates for improved abrasion and cut resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the web material is made thin to provide dexterity and grip, then dexterity and grip are improved, but cut resistance deteriorates
Solution Approach 1:
The patent applies different surface treatments to different regions of the glove. The palm surface receives a coating or laminate treatment to enhance cut resistance, while the finger surfaces remain as the original breathable web material to maintain dexterity and grip. This local differentiation resolves the contradiction by optimizing each region for its specific function.
Solution Approach 2:
The glove combines two different materials: a breathable web material (such as knitted fabric) for the base structure, and a coating or laminate layer (such as polyethylene or other cut-resistant materials) applied to the palm surface. This composite structure allows the glove to simultaneously achieve cut resistance from the laminate and dexterity/grip from the web material.
2Adaptability or versatility
If the web material is made thin to promote flexibility and dexterity, then flexibility and dexterity are improved, but cut resistance deteriorates
Solution Approach 1:
The patent applies different surface treatments to different regions of the glove. The palm surface receives a coating or laminate treatment to enhance cut resistance, while the finger surfaces remain as the original breathable web material to maintain dexterity and grip. This local differentiation resolves the contradiction by optimizing each region for its specific function.
Solution Approach 2:
The glove combines two different materials: a breathable web material (such as knitted fabric) for the base structure, and a coating or laminate layer (such as polyethylene or other cut-resistant materials) applied to the palm surface. This composite structure allows the glove to simultaneously achieve cut resistance from the laminate and dexterity/grip from the web material.
3Strength
If a coating or laminate is applied to provide cut resistance, then cut resistance is improved, but breathability deteriorates
Solution Approach 1:
The patent applies the coating or laminate only to the palm surface where cut resistance is most needed, while leaving the finger surfaces as open breathable web material. This selective application maintains breathability in the finger regions while providing cut protection where required.
Solution Approach 2:
The patent specifies that the coating or laminate should be porous or have permeability properties that allow breathability. This enables the protective layer to provide cut resistance while still permitting air and moisture vapor transmission to maintain glove breathability.
