SCBA Illuminated Universal Air Coupling for Low Visibility Rescue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firefighters face difficulties in locating and connecting to the Universal Air Coupling (UAC) of a self-contained breathing apparatus (SCBA) under low visibility conditions, such as those encountered during fires, due to reduced manual dexterity from turnout gear and gloves.
Innovation Solution
Incorporating a light source within the SCBA's carrier system that illuminates the UAC and its vicinity, controlled by a pressure sensor, to guide rapid intervention crew members in locating and connecting to the UAC, with adjustable illumination patterns indicating low air pressure levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If firefighters wear turnout gear and gloves for protection, then their safety is improved, but their manual dexterity deteriorates making it difficult to locate and connect to the UAC
Solution Approach 1:
The patent introduces an intermediary illumination system that mediates between the firefighter's impaired ability to locate the UAC and the need for rapid connection. The light source acts as a mediator that enhances visibility of the UAC and connection interface, allowing firefighters wearing protective gear to perform connections more easily without compromising their safety equipment.
2Adaptability or versatility
If firefighters operate in low visibility conditions during fires, then they can perform rescue operations, but the ability to locate and connect to the UAC deteriorates
Solution Approach 1:
The patent employs illumination that creates optical contrast to highlight the UAC and connection interface against the dark, smoky background. By introducing light that illuminates specific areas (the UAC and connection points), the system creates visual differentiation that makes these components easily detectable in low visibility conditions while allowing firefighters to maintain their operational capabilities in fire environments.
3Volume of moving object
If the UAC is made compact to fit within the SCBA system, then the device portability is improved, but the ease of locating and connecting to the UAC deteriorates
Solution Approach 1:
The patent applies local illumination to specific areas (the UAC and connection interface) rather than illuminating the entire SCBA system. This localized lighting approach highlights the small, compact UAC components and their connection points, making them easily locatable and operable despite their small size and integration within the compact SCBA system.

AI summary
A breathing system includes a tank for pressurized breathing gas, at least one regulator comprising a connection to which the tank is attachable, a universal air connector in fluid connection with the connection, and at least one light source, the light source, when illuminated, providing a guide to connect a connector in fluid connection with a secondary tank to the universal air connector to supply breathing gas to the tank.
