Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-pressure storage systems are used for fire extinguishing agents, then fire extinguishing effectiveness is maintained, but safety risks and explosion hazards increase
Solution Approach 1:
The invention utilizes phase transition by storing fire extinguishing agents as solids at ambient temperature and pressure, then transforming them into active gas-phase extinguishing substances through thermal decomposition and chemical reactions when exposed to fire conditions. This eliminates the need for high-pressure storage while maintaining extinguishing effectiveness.
Solution Approach 2:
The invention changes the physical and chemical parameters of the fire extinguishing system by using solid chemical compositions that decompose at specific temperature ranges. The solid agents are stored under normal conditions and transform into active extinguishing gases through controlled thermal decomposition, avoiding high-pressure storage requirements.
2Productivity
If aerosol fire extinguishing technology is used, then volume efficiency and storage period are improved, but fire extinguishing activity is attenuated after filtering through cooling layers
Solution Approach 1:
The invention incorporates strong oxidants in the chemical composition that enhance the reactivity and effectiveness of the fire extinguishing agent. These oxidants ensure that the chemical reactions proceed vigorously even after the agent passes through cooling layers, maintaining fire extinguishing activity despite the filtering process.
Solution Approach 2:
The invention uses composite chemical compositions combining multiple components including flame retardants, oxidants, reducing agents, and binding agents. This composite structure ensures both stable storage properties and high fire extinguishing effectiveness, overcoming the limitations of single-component aerosol systems.

Solution Approach 1:
The invention converts the harmful environmental impact of traditional halogenated agents into a beneficial solution by using environmentally friendly solid chemical compositions. These compositions decompose into non-toxic or low-toxicity products such as water, carbon dioxide, and inert gases, eliminating ozone layer damage while maintaining fire extinguishing effectiveness.
Solution Approach 2:
The invention changes the chemical composition parameters from halogenated hydrocarbons to environmentally friendly alternatives consisting of flame retardants, oxidants, and reducing agents. This parameter change eliminates the harmful environmental effects while preserving the fire extinguishing performance through controlled chemical reactions.
