Fire Extinguishing System with Segmented Evacuation Route Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fire extinguishing systems do not effectively differentiate between fire extinguishing means for protection targets and evacuation routes, potentially compromising life safety.
Innovation Solution
A fire extinguishing system that employs a first fire extinguishing part to supply a fire extinguishing agent to a protection target and a second fire extinguishing part to spray water along an evacuation route, with distinct activation temperatures and configurations to prioritize life saving by using different extinguishing means for each area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single fire extinguishing system is used for both protection targets and evacuation routes, then the system structure is simple, but life safety cannot be prioritized effectively
Solution Approach 1:
The fire extinguishing system is divided into two independent parts: a first fire extinguishing part for protection targets and a second fire extinguishing part for evacuation routes. This segmentation allows each part to be optimized for its specific function, with the second part prioritizing life safety through water spraying while the first part handles property protection with appropriate extinguishing agents.
Solution Approach 2:
Different fire extinguishing means are applied to different locations based on their specific requirements. The evacuation route receives water spraying from the second fire extinguishing part to ensure safe passage, while protection targets receive appropriate extinguishing agents from the first fire extinguishing part. This local differentiation ensures life safety is prioritized in evacuation areas.
2Reliability
If water is sprayed to protection targets first, then fire extinguishment may be effective, but equipment damage increases
Solution Approach 1:
The system applies different extinguishing media to different locations: the first fire extinguishing part uses appropriate agents (such as gas, powder, or foam) for protection targets to minimize equipment damage, while the second fire extinguishing part uses water for evacuation routes where life safety is the priority and equipment protection is not a concern.
Solution Approach 2:
By separating the fire extinguishing functions into two independent parts, the system can select optimal extinguishing agents for each application. The first part is designed to protect equipment with minimal damage, while the second part focuses solely on life safety through water spraying in evacuation areas.
3Adaptability or versatility
If the same activation temperature is used for both fire extinguishing parts, then the system is simple to control, but cannot respond appropriately to different fire scenarios
Solution Approach 1:
The first and second fire extinguishing parts are equipped with different activation temperatures suited to their respective functions. The second fire extinguishing part (evacuation route) uses a lower activation temperature to respond earlier and prioritize life safety, while the first fire extinguishing part (protection target) uses a higher activation temperature to respond only when necessary and preserve equipment.

AI summary
A fire extinguishing system comprises a first fire extinguishing part 10 that supplies a fire extinguishing agent to a protection target 90; and a second fire extinguishing part 20 that sprays water to an evacuation route 110. An activation temperature of the second fire extinguishing part 20 may be lower than an activation temperature of the first fire extinguishing part 10. The fire extinguishing system may further comprise a third fire extinguishing part 30 that sprays water to the protection target 90, wherein the third fire extinguishing part 30 may spray water after starting supply of the fire extinguishing agent by the first fire extinguishing part 10, and wherein the third fire extinguishing part 30 may be activated when the first fire extinguishing part 10 cannot extinguish a fire.
