Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If gas sensor detection is used to detect hazardous gas leakage, then the detection can be directly carried out, but the diffusion range of hazardous gas remains unknown during the detection period

Solution Approach 1:

The patent performs preliminary action by establishing a hazardous gas diffusion prediction model before actual leakage occurs. The model pre-calculates diffusion ranges based on various leakage scenarios, environmental factors, and sensor positions, enabling the system to predict the diffusion range immediately when leakage is detected, rather than remaining unknown

Inventive Principle:
