Capsule Fire Extinguisher With Thermal Release and Fire Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fire detectors require manual intervention to locate and use fire extinguishers, leading to delayed fire suppression and potential spread, especially in electrical fires, and lack automatic fire blocking capabilities.
Innovation Solution
A capsule-type fire extinguisher with an extinguishing module that automatically releases extinguishing materials upon fire detection, using a heating element to activate the extinguishing material and a separation membrane to control its release, while also blocking gas or electricity to prevent fire spread.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a general fire detector is used to detect fire, then fire detection capability is provided, but manual intervention is required to locate and use fire extinguishers leading to delayed fire suppression
Solution Approach 1:
The patent combines the fire detection function with the fire suppression function into a single integrated device. The fire detector is merged with an extinguishing capsule containing extinguishing material, so that when fire is detected, the system automatically suppresses the fire without requiring manual intervention to locate and use separate fire extinguishers.
Solution Approach 2:
The system performs self-service by automatically detecting fire and triggering the release of extinguishing material without human intervention. The fire detector automatically activates the heating element which releases the extinguishing capsule, enabling the system to suppress fire on its own.
2Object-affected harmful factors
If fire extinguishers are installed at specific positions, then fire suppression is available at those locations, but fire may spread to areas without extinguishers
Solution Approach 1:
The patent divides the fire protection system into multiple distributed extinguishing capsules that can be placed at various locations. Each capsule is a self-contained unit that can independently suppress fire at its location, providing widespread coverage without requiring a complex centralized extinguishing system.
3Extent of automation
If conventional fire extinguishers are used, then fire suppression is provided, but they lack automatic release capability and require manual operation
Solution Approach 1:
The patent replaces manual mechanical operation with an automated thermal activation system. A heating element heated by electricity or chemical reaction automatically triggers the release mechanism when fire is detected, substituting the need for manual mechanical activation.
Solution Approach 2:
The system utilizes phase transitions of materials in response to heat. The heating element undergoes thermal phase changes that trigger the release mechanism, and the extinguishing material may undergo phase transitions (such as expansion or vaporization) when exposed to fire conditions, enabling automatic activation.
4Loss of time
If fire detectors alarm manually, then fire warning is provided, but response time is delayed until manual intervention occurs
Solution Approach 1:
The system performs preliminary action by pre-positioning the extinguishing capsule within the integrated device and pre-programming the automatic release mechanism. When fire is detected, the system immediately activates the heating element and releases the extinguishing material without requiring any manual steps, thereby extending the golden time for fire suppression.
