Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gas fire extinguishing systems are used to achieve environmentally friendly fire extinguishing, then fire extinguishing effectiveness is improved, but storage pressure requirements increase and explosion risks rise
Solution Approach 1:
The invention changes the physical state parameter of the fire extinguishing agent from gaseous (requiring high pressure storage) to solid (stored at atmospheric pressure). The solid fire extinguishing agent undergoes phase transition to gas only during fire suppression, eliminating the need for high-pressure storage while maintaining fire extinguishing effectiveness.
Solution Approach 2:
The invention utilizes phase transition of the fire extinguishing agent from solid to gas during operation. The solid agent is heated by the fire or activation mechanism, sublimates or decomposes into active gas-phase fire suppressant, achieving the desired fire extinguishing effect without requiring high-pressure storage conditions.
2Reliability
If aerosol fire extinguishing agents are used to achieve chemical-physical fire suppression, then fire extinguishing effectiveness is improved, but cooling systems are required to prevent secondary fires
Solution Approach 1:
The invention converts the harmful high temperature and combustion byproducts into beneficial fire suppressant substances. The fire extinguishing agent undergoes controlled thermal decomposition or combustion reactions that generate active fire suppressant species (such as metal halide radicals) while consuming excess heat and combustion radicals, thereby suppressing the fire without requiring additional cooling systems.
Solution Approach 2:
The invention utilizes controlled oxidation reactions of the fire extinguishing agent that generate highly active fire suppressant species. The chemical reactions produce radicals and compounds that accelerate the termination of combustion chain reactions, achieving rapid fire suppression through chemical inhibition rather than physical cooling.
3Object-affected harmful factors
If solid fire extinguishing agents are used to eliminate high-pressure storage, then safety is improved, but fire extinguishing substance generation efficiency must be enhanced
Solution Approach 1:
The invention employs phase transition from solid to gas through sublimation or decomposition to generate fire extinguishing substances. This phase change occurs rapidly when the solid agent is exposed to fire heat or activation, ensuring high generation efficiency of active fire suppressant gas without requiring high-pressure storage conditions.
Solution Approach 2:
The invention utilizes controlled chemical reactions including oxidation, decomposition, or combustion of the solid fire extinguishing agent to generate active fire suppressant species. These chemical transformations occur rapidly under fire conditions, ensuring high productivity of fire extinguishing substances while maintaining storage safety at atmospheric pressure.
