Arc flash protection glove
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing arc flash protection gloves lack adequate protection while compromising flexibility, wearability, and mobility due to their fire-resistant properties.
Innovation Solution
A fire-resistant arc flash protection glove with a liner featuring a backside coating portion and a palm side coating portion, where the backside coating covers at least 4 cm² and has an average weight within 5-80% of the palm side coating, providing comprehensive protection while maintaining flexibility and mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fire-resistant coating is applied to the entire glove, then arc flash protection is improved, but weight and flexibility deteriorate
Solution Approach 1:
The patent applies fire-resistant coating selectively to specific high-risk areas (palm side center portion, palm side finger portions, and backside center portion) rather than the entire glove. This localized approach provides adequate arc flash protection where needed while reducing overall coating weight and maintaining flexibility in less critical areas.
2Reliability
If fire-resistant coating is applied to the entire glove, then arc flash protection is improved, but flexibility and mobility deteriorate
Solution Approach 1:
The coating is applied locally to critical areas only, leaving non-critical areas of the glove uncoated or lightly coated. This maintains the natural flexibility and mobility of the glove material in areas where full coating is not necessary for protection.
Solution Approach 2:
The glove is divided into different zones with different coating densities: heavily coated critical areas (palm center, palm fingers, backside center) and lightly coated or uncoated non-critical areas. This segmentation allows the glove to provide protection where needed while maintaining flexibility elsewhere.
3Ease of manufacture
If uniform coating weight is applied to both palm side and backside, then protection is simplified, but material efficiency deteriorates
Solution Approach 1:
Different coating weights are applied to different sides of the glove based on their specific protection needs. The palm side receives heavier coating (higher arc rating requirement) while the backside receives lighter coating (lower arc rating requirement), optimizing material usage while maintaining protection where critical.
