Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flame-retardant protective gloves often compromise on comfort, grip, and ease of washing due to rigid materials and poor wet condition performance, and existing designs face challenges with material combinations that affect usability and safety.
Innovation Solution
A flame-retardant protective glove with a multilayer material composition that includes a silicone-coated aramide fiber layer for strength and heat resistance, a polyamide-aramide fiber layer for outer shell optimization, and a liquid-tight, breathable membrane for enhanced grip and ergonomic design, allowing for secure washing and decontamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plastic coating is applied to leather for flame protection, then flame resistance is improved, but the glove becomes rigid and difficult to wash
Solution Approach 1:
The glove is divided into multiple functional layers: outer shell (leather or synthetic), insulating lining (refractory material), and inner lining. Each layer serves specific purposes, allowing the flame-resistant outer shell to be separated from the flexible inner components, maintaining overall flexibility while providing protection.
Solution Approach 2:
The glove uses composite material construction combining leather/synthetic outer shell with refractory insulating material and breathable membrane layers. This composite structure provides flame resistance while maintaining flexibility and washability through careful material selection and layering.
2Ease of manufacture
If non-leather materials are used for flame resistance, then washability is improved, but grip in wet conditions deteriorates
Solution Approach 1:
Different regions of the glove have different material properties optimized for their specific functions. The palm and finger areas use materials with superior wet grip characteristics, while other areas use materials optimized for flame resistance and washability. This localized material differentiation maintains grip ability while preserving ease of washing.
3Reliability
If multiple material layers are combined for protection, then flame resistance is improved, but the complexity of washing and decontamination increases
Solution Approach 1:
The design separates the flame-resistant outer shell from the inner lining and insulation layers, allowing the outer shell to be removed and washed separately. This extraction of the soiled outer layer simplifies the washing process while maintaining the protective function of the multi-layer construction.
