Optical Waveguide Rupture Body for Fire Trigger Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire protection systems, such as sprinkler and smoke evacuation damper systems, struggle with inadequate localization of triggered elements, leading to delayed firefighting response and potential damage from false triggers.
Innovation Solution
Integrate an optical waveguide with a predetermined breaking point into the rupture body of fire protection elements, which is destroyed upon activation, allowing for precise identification of the trigger location through optical signal disruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional rupture bodies are used in fire protection systems, then the system can detect triggering through pressure changes, but the location of the triggered element cannot be accurately determined
Solution Approach 1:
An optical waveguide is introduced as an intermediary component between the rupture body and the detection system. The waveguide transmits optical signals from the rupture body to a remote evaluation unit, enabling accurate location identification without direct mechanical connection to the water supply system. This intermediary allows precise measurement of trigger location while maintaining system simplicity.
2Measurement precision
If optical waveguides are integrated into rupture bodies, then trigger location can be precisely identified, but the device complexity increases
Solution Approach 1:
The optical waveguide serves multiple functions: it acts as a structural component of the rupture body, a signal transmission medium, and a location identification marker. By making the waveguide multi-functional, the system achieves precise location identification without proportionally increasing device complexity, as the waveguide performs several roles simultaneously.
3Reliability
If optical waveguides are used for location identification, then false triggering damage can be reduced, but the cost of the fire protection system increases
Solution Approach 1:
The optical waveguide system is self-activating and self-locating. When the rupture body bursts, the optical waveguide automatically breaks at a predetermined location, and the resulting optical signal transmission interruption automatically identifies the trigger location without requiring external intervention or complex processing systems. This self-service mechanism improves reliability while keeping the system relatively simple.
