Fireproof Footwear with Adsorption Layer for Toxic Substance Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firefighting boots lack effective protection against both high temperatures and toxic substances, as they often fail to provide adequate flame resistance and efficient barrier against chemical or biological toxins.
Innovation Solution
A multilayered boot design with a fire-resistant outer layer coated with phosphoric acid compounds or fluorinated polymers, combined with an inner adsorption layer using activated carbon to absorb toxic substances, ensuring protection against both flames and contaminants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional boot material is used, then the boot is easy to manufacture and wear, but it provides insufficient protection against high temperatures and toxic substances
Solution Approach 1:
The patent applies composite materials by combining conventional boot material with fire-resistant coatings and impregnations. The outer layer receives a fire-resistant coating on its outer surface and fire-resistant impregnation within its material structure, creating a composite structure that maintains the base material's wearability while adding thermal and chemical protection capabilities.
Solution Approach 2:
The protective system is segmented into distinct functional layers: the outer layer with its coating and impregnation, and the inner layer with its own coating and impregnation. This segmentation allows each layer to be optimized for specific protection requirements while maintaining overall system functionality.
2Reliability
If single-layer boot material is used, then the structure is simple, but it cannot simultaneously provide flame resistance and toxin absorption
Solution Approach 1:
The boot is divided into an outer layer and an inner layer, each with distinct protective functions. The outer layer's coating and impregnation provide flame resistance and chemical barrier properties, while the inner layer's coating and impregnation provide additional flame resistance and toxin absorption, allowing simultaneous protection against multiple hazards.
Solution Approach 2:
Each layer is transformed into a composite structure through the application of coatings and impregnations. The outer layer combines base material with fire-resistant coating and impregnation, while the inner layer combines base material with fire-resistant coating and toxin-absorbing impregnation, creating multi-functional composite structures.
