Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If infrared light is irradiated at a fixed position on the gas, then the detection system is simple, but the detection sensitivity and analysis accuracy degrade due to gas concentration distribution
Solution Approach 1:
The system uses a camera to capture the concentration distribution of the gas, feeds this information back to determine the optimal irradiation position, and adjusts the infrared light irradiation position accordingly. This closed-loop feedback mechanism ensures that the infrared light always targets the region with the most suitable gas concentration for detection, resolving the contradiction between system simplicity and detection accuracy.
Solution Approach 2:
The irradiation position of the infrared light is made dynamic rather than fixed. The system continuously adjusts the irradiation position based on the real-time concentration distribution of the gas captured by the camera. This dynamic adaptation allows the system to maintain high detection sensitivity and analysis accuracy despite variations in gas concentration distribution.
2Measurement precision
If the irradiation position of infrared light is adjusted based on gas concentration distribution, then detection sensitivity improves, but the device complexity increases
Solution Approach 1:
The camera serves multiple functions: it captures the concentration distribution of the gas for analysis, provides feedback for determining the optimal irradiation position, and enables visualization of the gas distribution. By making the camera multi-functional, the system achieves improved detection sensitivity without proportionally increasing device complexity, as one component performs multiple critical roles.
3Area of stationary object
If infrared light irradiates regions with varying gas concentrations, then the detection area is large, but the analysis accuracy degrades
Solution Approach 1:
Instead of uniformly irradiating a large area with constant quality, the system applies local quality by adjusting the irradiation position based on the local gas concentration distribution. The infrared light targets specific regions with optimal concentration characteristics identified by the camera, ensuring high analysis accuracy in the detection area while adapting to local variations in gas concentration.
