Innovation Solution
An aerosol fire extinguishing agent composition containing an aerosol generating agent component such as ammonia, alkali metals, or halogens, and an oxidizing agent component like nitrates, chlorates, or metal oxides, which generates an aerosol upon ignition, allowing for a compact and lightweight fire extinguishing device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If powder-type fire extinguishing agents are used and diffused as fine powder toward the flame, then fire extinguishing function is achieved through radical generation, but the container becomes large, bulky, and heavy due to high-pressure resistance requirements
Solution Approach 1:
The invention changes the physical state of the fire extinguishing agent from solid powder to liquid composition, and changes the delivery mechanism from pressurized gas propulsion to combustion-driven aerosol generation. This fundamental parameter change eliminates the need for high-pressure containers while maintaining fire extinguishing effectiveness through aerosol delivery of extinguishing agents
Solution Approach 2:
The invention replaces the mechanical pressurization system (high-pressure container with gas propellant) with a chemical combustion system. The combustion of fuel components generates heat and pressure in-situ to vaporize and aerosolize the extinguishing agent, eliminating the need for heavy high-pressure resistant containers while achieving the same delivery function
2Reliability
If powder-type fire extinguishing agents are diffused as fine powder, then fire extinguishing function is achieved, but the device becomes less compact due to large container size
Solution Approach 1:
The invention changes the physical state from solid powder to liquid composition that generates aerosol upon combustion. This allows the extinguishing agent to be delivered in a compact liquid form factor while generating the necessary fine particulate aerosol delivery mechanism through combustion, achieving both compactness and functional effectiveness
Solution Approach 2:
The invention replaces the mechanical powder diffusion system with a combustion-based aerosol generation system. The combustion process naturally creates the fine aerosol particles needed for fire suppression without requiring large storage containers, achieving compact device volume while maintaining extinguishing function
