Solution Overview
Problem
There is currently no tool or method capable of inspecting and performing pressure measurements on pressurized oxygen gas containers outside of an aircraft, which is necessary for ensuring their adequacy and safety.
Innovation Solution
A pressure measurement and leak test tool that includes a housing with a wired connection to a bottle head assembly on the container, featuring a pressure transducer to measure internal pressure and a display for showing DC voltage, allowing operators to verify the container's pressure and detect gross leaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no inspection tool is used outside the aircraft, then the container cannot be inspected for pressure and leaks, but the container remains unsafe for use
Solution Approach 1:
The patent introduces an intermediary inspection tool that connects to the bottle head assembly's electrical connector. This tool includes a pressure transducer that interfaces with the container's internal pressure through the existing electrical connection infrastructure, enabling external inspection without requiring direct access to the container interior or complex disassembly procedures.
Solution Approach 2:
The patent replaces potential mechanical inspection methods with an electrical/electronic measurement system. The pressure transducer converts mechanical pressure into an electrical signal that can be read by the information handling system, eliminating the need for mechanical gauges or physical inspection methods that would be more complex to implement externally.
2Ease of operation
If a pressure measurement tool is developed, then container pressure can be measured outside aircraft, but the tool requires electrical connectors and power supply infrastructure
Solution Approach 1:
The inspection tool is designed to interface with the existing bottle head assembly electrical connector, which serves multiple functions including power supply and data transmission. This universal interface allows the same connector infrastructure to support both the original bottle operation and the inspection measurement functions, reducing the need for separate dedicated connections.
Solution Approach 2:
The bottle head assembly's electrical connector and power supply system serve dual purposes: their original function for bottle operation and the additional function of powering and communicating with the pressure transducer. The existing infrastructure essentially serves itself by accommodating the inspection tool without requiring separate dedicated systems.
3Measurement precision
If pressure transducer is integrated into bottle head assembly, then internal pressure can be measured, but the bottle head assembly becomes more complex
Solution Approach 1:
The patent merges the pressure transducer with the existing bottle head assembly, combining the measurement function with the existing electrical connector infrastructure. This integration allows the pressure sensing capability to be incorporated without requiring separate external measurement devices, thereby reducing overall system complexity despite adding measurement functionality.
