Solution Overview
Problem
Current testing methods for hydrogen leaks are inadequate, as they fail to accurately simulate small or variable leak rates and assess the ignition risks and damage potential of hydrogen gas mixtures, particularly due to the difficulty in detecting ultraviolet emissions and the lack of comprehensive safety protocols.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If typical fire testing rigs are designed to create and test the largest foreseeable fire, then the testing capability for large fires is improved, but the ability to test small or variable leak rates deteriorates
Solution Approach 1:
The invention segments the testing capability by providing multiple interchangeable leak plates, each with different aperture sizes. This allows the testing system to be divided into multiple configuration options, enabling both large fire testing and small leak rate testing using the same base apparatus.
Solution Approach 2:
The invention introduces dynamic adaptability through interchangeable leak plates that can be swapped based on testing requirements. The system transitions from a fixed configuration to a dynamic one where the leak plate aperture can be changed to match the specific leak rate scenario being tested, whether small or large.
2Object-affected harmful factors
If hydrogen gas is used as fuel, then environmental benefits are improved, but safety challenges due to broad flammability range and difficulty in detecting ultraviolet emissions worsen
Solution Approach 1:
The invention introduces an intermediary detection system that captures ultraviolet emissions from hydrogen combustion. The specialized sensors and imaging systems act as mediators between the invisible UV radiation and the observers, converting the undetectable emissions into measurable signals that can be monitored and analyzed.
Solution Approach 2:
The invention employs detection methods that visualize the ultraviolet emissions from hydrogen combustion, effectively translating the invisible into a detectable form. The specialized sensors detect the characteristic UV radiation spectrum, providing visual or electronic indicators of hydrogen combustion that would otherwise be imperceptible.
