Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fire suppression methods, such as water deployment and fire retardant coatings, are inefficient and can cause damage, and existing fire retardant materials require continuous application and are not effective against ember attacks, which are a significant mechanism of bushfire propagation.
Innovation Solution
A fire suppressant material comprising zeolite particles with an internal porous structure that releases fire extinguishing substances like carbon dioxide or water vapor when activated by heat, creating a barrier to oxygen and effectively suppressing fires without water damage, and can be reused by reabsorbing gases from the atmosphere.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water is used to suppress fires, then fire suppression is achieved, but extensive damage is caused to property and continuous replenishment is required
Solution Approach 1:
The invention changes the physical-chemical parameters of the fire suppressant by using zeolite particles that release fire extinguishing substances (carbon dioxide or water vapor) through heat activation rather than direct water application. This parameter change allows fire suppression without the harmful effects of large water volumes, achieving both fire extinction and property protection
Solution Approach 2:
The zeolite particles undergo phase transition when activated by heat, releasing the contained fire extinguishing substances from their porous structure. This phase transition mechanism enables the material to transform from a solid storage state to an active fire suppression state, providing rapid fire suppression without water damage
2Reliability
If conventional fire retardant coatings are applied, then flame spread is retarded, but continuous application is required and they are ineffective against ember attacks
Solution Approach 1:
The fire extinguishing substances are pre-loaded into the zeolite particles during manufacturing, creating a self-contained fire suppression system. This preliminary action eliminates the need for continuous application or reapplication, as the particles contain their own fire suppressant supply that activates automatically when exposed to fire or ember temperatures
Solution Approach 2:
The zeolite particles are designed to be self-activating through heat exposure, automatically releasing their fire extinguishing substances without requiring external intervention or reapplication. This self-service mechanism provides long-lasting fire protection that conventional coatings cannot achieve, particularly against ember attacks
3Productivity
If fire suppressant material is used to suppress fires, then fire is extinguished, but the material cannot be reused
Solution Approach 1:
After the zeolite particles release their fire extinguishing substances during fire suppression, they can be recovered and regenerated by reabsorbing gases from the atmosphere. This discarding and recovering process allows the material to be reused multiple times, eliminating the need for continuous replacement and reducing waste
Solution Approach 2:
The zeolite particles can change their absorption parameters to reabsorb fire extinguishing substances from the atmosphere after release. This parameter change enables the material to transition from an exhausted state back to an active state, allowing regeneration and reuse without loss of functionality
