Domestic Appliance Fire-Prevention Medium With Low-Temperature Gas Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical domestic appliances pose a fire risk due to contact faults, excessive heat generation, and overloading, with existing fire protection materials being less effective and potentially hazardous to health.
Innovation Solution
An electrical domestic appliance equipped with a fire protection medium that includes an active substance releasing water, carbon dioxide, and/or nitrogen at temperatures below 100°C, comprising a core with the active substance and a shell, where the active substance is preferably a hydrate such as alum, gypsum, or zeolite, embedded in a carrier material like a fiber fabric or plastic molded part, designed to delay fire spread and extinguish fires without sensors or mechanical elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fire protection materials are used in electrical domestic appliances, then fire safety is improved, but health risks increase due to potentially hazardous substances
Solution Approach 1:
The patent changes the chemical composition parameters of fire protection materials by using hydrates (alum, gypsum, zeolite) that decompose at specific temperature thresholds below 100°C, releasing water and gases. This parameter change enables effective fire protection while avoiding toxic substances, thus resolving the contradiction between fire safety and health risks
Solution Approach 2:
The patent employs composite material structures combining hydrates with carrier materials and shell enclosures. This composite approach creates a fire protection system that is both effective (through hydrate decomposition) and safe (through controlled release mechanisms), addressing the contradiction between reliability and harmful factors
2Reliability
If existing fire protection materials are used, then fire resistance is improved, but response effectiveness decreases due to high activation temperatures
Solution Approach 1:
The patent modifies the thermal decomposition parameters of fire protection materials by selecting hydrates with decomposition temperatures below 100°C. This parameter change ensures early activation at low temperatures, improving response effectiveness while maintaining fire resistance through the fireproofing effect of released water and gases
