Deployable Sprinkler Propellant Deployment False Alarm Suppressant Waste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Deployable sprinkler fire suppression systems face inefficiencies due to the labor-intensive manual reset process and excessive use of suppressant during false alarms, which wastes resources and requires frequent recharging.
Innovation Solution
A deployable sprinkler fire suppression system that uses propellant to prime and deploy sprinklers instead of suppressant, allowing for automatic retraction and recharge of propellant after false alarms, reducing the need for suppressant usage and manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If suppressant is used to deploy the sprinkler, then the sprinkler can be deployed to a ready state, but suppressant is consumed during false alarms requiring frequent recharging
Solution Approach 1:
The system segments the fluid supply into two separate sources: a propellant source for deployment and a suppressant source for fire suppression. This segmentation allows the sprinkler to be deployed using propellant without consuming suppressant, thereby resolving the contradiction between reliable deployment and suppressant conservation during false alarms
Solution Approach 2:
The system introduces propellant as an intermediary substance to facilitate sprinkler deployment. The propellant acts as a mediator that enables the deployment function without depleting the suppressant resource, allowing the sprinkler to transition to a ready state while preserving suppressant for actual fire suppression events
2Volume of moving object
If deployable sprinklers are used, then the system can be compact and protected, but manual reset is labour intensive after deployment
Solution Approach 1:
The system implements self-service through automatic retraction mechanisms that return the sprinkler to its protected position after deployment. The propellant source can be automatically recharged, and the sprinkler head automatically retracts into its compact state, eliminating the need for manual reset operations and reducing labor requirements
3Reliability
If the system errs on the side of sensitivity for safety, then fire detection reliability is improved, but false alarms increase consuming suppressant
Solution Approach 1:
By segmenting the fluid supply into separate propellant and suppressant sources, the system allows sensitive detection thresholds to be maintained for safety while preventing suppressant consumption during false alarms, as propellant is used for deployment rather than suppressant
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces the burden of false alarms by minimizing suppressant consumption and simplifying the reset process, enhancing system reliability and reducing maintenance needs while maintaining safety standards.
Implementation Method 1
the system is arranged to deploy the sprinkler by pressurising the supply pipe by supplying propellant from the propellant source to the sprinkler
Implementation Method 2
a suppressant source arranged to discharge suppressant from the sprinkler during a suppression event

AI summary
A deployable sprinkler fire suppression system and a method of using a deployable sprinkler fire suppression system. The system comprises: a deployable sprinkler 110, arranged to be deployed prior to a suppression event; a suppressant source 120 arranged to discharge suppressant from the sprinkler 110 during the suppression event; and a propellant source 140 arranged to supply propellant to the sprinkler 110 to deploy the sprinkler 110 prior to the suppression event. The system 100 is arranged to deploy the sprinkler 110 by supplying propellant from the propellant source 140 to the sprinkler 110 prior to supplying suppressant from the suppressant source 120.
