Arc Flash Glove Multilayer Palm Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing arc fault protective gloves face a challenge in providing sufficient protection against thermal effects while maintaining finger mobility and comfort, as thick and stiff materials required for protection restrict hand movement.
Innovation Solution
The arc fault protective glove features a multilayer palm section with a first layer and a second layer sewn together using an aramid thread, providing partial reinforcement to the palm without stiffening the entire glove, thus maintaining finger mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the protective glove is made with thick and stable materials to ensure sufficient protection against thermal effects, then the protection level is improved, but the stiffness of the glove increases and restricts the freedom of movement of the hand
Solution Approach 1:
The protective glove is divided into multiple functional layers with different properties. The palm section has a multilayer structure (first layer, second layer, and third layer) for thermal protection, while the finger elements have a simpler single-layer structure for mobility. This segmentation allows each region to be optimized for its specific function.
Solution Approach 2:
Different regions of the glove are assigned different material properties and layer configurations. The palm section receives enhanced thermal protection with multiple layers, while the finger elements maintain flexibility with fewer layers. This local differentiation resolves the contradiction by providing protection where needed without sacrificing mobility where it is critical.
2Reliability
If the palm section is reinforced with multiple layers to protect against thermal effects, then the protection level is improved, but the complexity of the glove structure increases
Solution Approach 1:
The glove structure is segmented into distinct sections (palm section with multilayer structure, finger elements with single layer, glove back) that can be manufactured separately and then assembled. This reduces the complexity of manufacturing each component while achieving the overall protection goal.
Solution Approach 2:
Multiple layers in the palm section are combined through sewing connections to create a unified protective structure. The first layer, second layer, and third layer work together as an integrated system, providing cumulative protection while maintaining a manageable structural complexity through systematic assembly.

AI summary
The invention relates to an arc fault protective glove (10) for the protection against the thermal effects of an arc fault, wherein the arc fault protective glove (10) includes a palm section (26) which is assigned to a palm when the arc fault protective glove (10) is worn, and a glove back (54) opposite to the palm section (26), which is assigned to the back of a hand when the arc fault protective glove (10) is worn. The palm section (26) has a multilayer structure. The multilayer structure comprises at least a first layer (24) and a second layer (32), wherein the first layer (24) is sewn to the second layer (32) in an edge area (28) of the second layer (32)
