Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing leakage detection systems struggle to effectively detect small leaks of substances like hydrogen, which are difficult to sense due to their subtle nature.
Innovation Solution
A leakage sensitive arrangement using an emission generating compound is applied outside an enclosure, which reacts with leaking hydrogen to produce detectable emissions, such as smoke and CO, that can be detected by a sensor, and is integrated with a fire-retardant thermal insulation layer to enhance detection capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional detector technologies are used, then the detection system is simple, but small leakage incidents are invisible and cannot be detected
Solution Approach 1:
An emission generating compound is introduced as an intermediary substance between the leaking hydrogen and the detector. The compound reacts with the leaked hydrogen to produce detectable emissions (smoke, CO, CO2, NOx), thereby enabling detection of small leaks that would otherwise be invisible to conventional detectors
Solution Approach 2:
The detection approach changes from directly detecting hydrogen parameters to detecting combustion product parameters. By converting the invisible hydrogen leak into visible combustion emissions through chemical reaction, the detection sensitivity is significantly improved
2Measurement precision
If an emission generating compound is applied to enhance detection, then leakage detection sensitivity is improved, but the device complexity increases
Solution Approach 1:
The emission generating compound layer is merged with the fire-retardant thermal insulation layer, combining two functional layers into one integrated structure. This reduces overall system complexity while maintaining both insulation and enhanced detection capabilities
Solution Approach 2:
The emission generating compound layer serves multiple functions: it acts as part of the thermal insulation system and simultaneously provides enhanced leakage detection capability. This multi-functionality eliminates the need for separate detection components
3Speed
If the emission generating compound reacts quickly with low total heat load, then detection response is fast, but the reaction intensity may be insufficient
Solution Approach 1:
The compound is designed to change its reaction parameters based on the substance it encounters. When exposed to hydrogen, it reacts quickly with low heat load for fast detection. When exposed to other substances like hydrocarbons, it reacts more intensely, ensuring reliable detection across different leak scenarios

This solution allows for the detection of previously invisible leakage incidents, enabling immediate action to stop hydrogen supply and extinguish micro-flames, thereby ensuring equipment safety and operation.
Implementation Method 1
The applied emission generating compound is configured to be exposed to an activation energy resulting from leaking substance from the inside of the enclosure. The activation energy causes a chemical reaction of the emission generating compound.
Implementation Method 2
the emission generating compound is easily oxidizable, e.g. ignitable, and oxidizes quickly with low total heat load. As an example, the emission generating compound burns down quickly with low total fire heat load.
Implementation Method 3
The chemical reaction actively produces an emission detectable by a detector.
