Ceiling Gas Detector Cover With A Gas-Retaining Collar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hydrogen leakage detection in fuel cell electric vehicles and other equipment is inefficient due to the need for multiple detectors, increasing costs, and existing solutions do not effectively stabilize gas concentration near detectors for reliable detection.
Innovation Solution
A cover for gas detectors, comprising a flat plate portion attached to a ceiling surface with a collar portion extending downward to surround the detector, stabilizing gas concentration by retaining leaked gas near the detector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple hydrogen detectors are installed to detect hydrogen leakage from various components, then the detection coverage is improved, but the cost increases
Solution Approach 1:
The collar portion acts as an intermediary structure between the ceiling surface and the gas detector. It guides and concentrates drifting gas toward the detector, enabling a single detector to effectively monitor a larger area and multiple potential leakage sources, thereby reducing the total number of detectors needed while maintaining comprehensive detection coverage
2Measurement precision
If gas detectors are installed without a cover structure, then the device complexity is reduced, but the gas concentration stability near the detector deteriorates
Solution Approach 1:
The collar portion creates a localized zone around the gas detector with distinct functional properties. This local structure concentrates and retains gas in the vicinity of the detector, ensuring stable gas concentration at the detection point without requiring complex modifications to the entire detection system or ceiling structure
