Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fire extinguishing systems using fire extinguishers from storage containers face limitations in wide protected areas, where the fire extinguisher is insufficient due to short ejection times and long distances to ignition points, making effective firefighting difficult.
Innovation Solution
A fire extinguishing system with a fire extinguisher storage container, multiple ejecting units, a heat source detecting unit, and a control unit that includes an ignition point judging unit, fire determining unit, ejecting unit selecting unit, and operation direction calculating unit, which selects and directs the ejection of fire extinguishers based on detected heat source information to ensure effective firefighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If fire extinguishers are ejected from all ejection ports simultaneously like sprinklers, then fire coverage is improved, but ejection time becomes extremely short and fire fighting cannot be sufficiently carried out
Solution Approach 1:
The system divides the protected area into multiple zones with separate ejection ports, and selectively activates only the ejection ports in the zone containing the fire source. This segmentation allows concentrated fire extinguishing action at the fire location rather than simultaneous ejection from all ports, extending effective fire fighting duration.
Solution Approach 2:
The heat source detecting unit continuously monitors the protected area before fire occurs, and the control unit pre-identifies which ejection ports should be activated based on detected heat source position. This preliminary detection and preparation enables rapid response when fire breaks out without the delay of system-wide activation.
2Area of stationary object
If the protected area is wide, then coverage area is improved, but distance to ignition point becomes long and it is difficult to sufficiently carry out fire fighting
Solution Approach 1:
The system transitions from centralized fire extinguishing to distributed multi-point ejection by activating multiple ejection ports simultaneously at different locations within the wide protected area. Each ejection port targets its local fire source, effectively reducing the maximum distance any single extinguisher must travel while maintaining wide area coverage.
Solution Approach 2:
The control unit dynamically adjusts the number and location of active ejection ports based on the position and characteristics of the fire source. When the protected area is wide, multiple ejection ports are activated to reduce ejection distance, while in smaller areas, fewer ports are used to avoid waste.
3Device complexity
If a limited fire extinguisher is used, then device complexity is reduced, but fire fighting effectiveness decreases in wide areas
Solution Approach 1:
Standard fire extinguishers are used in multiple ejection ports throughout the protected area, with each extinguisher designed to handle typical fire scenarios. The control unit's intelligent selection and directional adjustment of these universal extinguishers compensates for their limited individual capacity, maintaining fire fighting effectiveness across wide areas without requiring specialized equipment at each location.
