Dual-Outlet Air Tank Adapter for Firefighter Breathing and Chainsaw
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firefighters face challenges in areas with breathable air deprivation, where both personal breathing apparatuses and internal combustion-driven tools like chainsaws struggle to function effectively, leading to reduced performance or safety risks due to inadequate air supply.
Innovation Solution
A system that simultaneously supplies air to a firefighter's personal breathing apparatus and an internal combustion engine-driven tool, such as a chainsaw, using a compressed air source with a dual-outlet tank and an adapter that connects to both the breathing apparatus and the tool's air intake, ensuring both can operate at full capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a firefighter uses a personal breathing apparatus fed by a compressed air tank, then the firefighter can breathe in air-deprived areas, but the internal combustion driven appliance must run at reduced horsepower or not at all on the remaining air or oxygen
Solution Approach 1:
The compressed air tank is divided into two separate supply lines: one line delivers air to the firefighter's breathing apparatus through a demand valve, and the other line delivers air to the internal combustion engine's air intake through an adapter. This segmentation allows independent air supply to both the firefighter and the appliance, resolving the contradiction between maintaining breathing apparatus functionality and preserving appliance horsepower.
2Reliability
If air is supplied to the firefighter's breathing apparatus, then personal safety is ensured, but the internal combustion engine receives insufficient air for full operation
Solution Approach 1:
The air supply system is segmented into two independent channels from the same compressed air tank. The first channel supplies air to the breathing apparatus via a demand valve that regulates air flow based on the firefighter's respiratory needs. The second channel supplies air directly to the internal combustion engine through an adapter connected to the engine's air intake. This segmentation ensures both the firefighter's safety and the tool's full operational effectiveness are maintained simultaneously.
3Quantity of substance
If a single compressed air tank is used for both breathing apparatus and internal combustion engine, then air supply is limited, but dual supply ensures both can operate at full capacity
Solution Approach 1:
The single compressed air tank is equipped with two separate outlet connections, each leading to independent supply lines. One supply line connects to the breathing apparatus through a demand valve, while the other supply line connects to the internal combustion engine through an adapter. This segmentation of the air distribution system allows full air supply to both devices simultaneously while maintaining a relatively simple overall system configuration using a single tank.

Function Achieved in This Case
This solution enables firefighters to maintain effective tool operation and personal safety by providing sufficient air to both the breathing apparatus and the internal combustion engine, although it requires careful monitoring of air supply to prevent depletion and ensure timely exit or tool shutdown.

AI summary
A system for simultaneously supplying compressed air to the personal breathing apparatus of a firefighter and to an internal combustion engine appliance, such as a chainsaw. The supply of air intake of the chainsaw is provided by means of an adapter which is configured to attach to both the air intake of the chainsaw and to a demand valve-type regulator.
