Vehicle Fire Suppression External Fluid Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire suppression systems in vehicles often run out of pressurized suppressant before extinguishing fires completely and require hazardous manual connection of external sources during emergencies.
Innovation Solution
A fire suppression apparatus with angled funnels and one-way valves that allow external fire suppressant fluid to be directed into the vehicle through a delivery pipe, ensuring continuous flow and reducing manual intervention risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an internal source of pressurised fire suppressant is used, then the system can automatically suppress fires, but the suppressant may be depleted before the fire is fully extinguished
Solution Approach 1:
The patent introduces an intermediary external fire suppressant source that can be connected to the vehicle's fire suppression system. This external source acts as a mediator to replenish or extend the suppressant supply when the internal source is depleted, allowing continuous fire suppression without requiring the operator to manually intervene in hazardous conditions.
2Quantity of substance
If an external source of pressurised fire suppressant is connected via an inlet nozzle, then continuous suppressant supply is possible, but the operator must physically connect the external source which is hazardous during fire emergencies
Solution Approach 1:
The patent implements a self-service mechanism where the fire suppression system automatically receives suppressant from an external source without requiring operator intervention. The system includes an external connection interface that can be pre-connected or automatically coupled, allowing the vehicle to self-replenish suppressant reserves or receive continuous supply while eliminating the need for operators to physically connect hoses or nozzles during hazardous fire conditions.
3Adaptability or versatility
If the delivery pipe extends from external location into the vehicle, then external suppressant can be delivered internally, but the system complexity increases with funnels and flow devices
Solution Approach 1:
The patent designs the delivery pipe system with multi-functionality to reduce overall complexity. The delivery pipe serves multiple purposes: it acts as both the fluid transport conduit and incorporates integrated flow control features. The funnel structure is designed to be universal, accommodating different external suppressant sources while maintaining a standardized connection interface, thereby reducing the need for multiple specialized components.
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
The apparatus ensures sustained fire suppression by maintaining pressurization and allowing external fire suppressant fluid to be directed into the vehicle safely, even when manual connection is hazardous, thereby preventing re-ignition and enhancing safety.
Implementation Method 1
a first directional flow device, the first directional flow device being located so as to allow flow of the fire suppressant fluid in a single direction from the first funnel into the delivery pipe
Implementation Method 2
the delivery pipe includes a delivery portion having a plurality of apertures. In another aspect, the plurality of apertures are adapted to provide a spray
Implementation Method 3
a first funnel in fluid communication with a delivery pipe, the funnel being arranged to receive the fire suppressant fluid from a first location external to the vehicle
