Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are installed separately in the weathering chamber, then comprehensive environmental parameters can be measured, but the device complexity and space requirements increase
Solution Approach 1:
The patent combines multiple sensors (black standard sensor, UV radiation sensor, air temperature sensor, and humidity sensor) into a single integrated sensor device with a common housing. This merging approach allows comprehensive environmental parameter measurement while reducing the number of separate components, simplifying installation, and minimizing space requirements in the weathering chamber.
2Device complexity
If a compact integrated sensor device is used, then device complexity is reduced, but sensor functionality and measurement capabilities must be maintained
Solution Approach 1:
The integrated sensor device is designed to perform multiple measurement functions simultaneously through a single housing. The device incorporates a black standard sensor for temperature measurement, a UV radiation sensor for radiation intensity detection, an air temperature sensor, and a humidity sensor, all within one compact unit. This multi-functional design maintains comprehensive measurement capabilities while reducing overall system complexity.
