Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional systems are used to determine emissivity and surface roughness, then the measurement process is simpler, but the measurement precision and accuracy deteriorate due to noise sensitivity and inability to control illuminated region
Solution Approach 1:
The system segments the radiation detection into multiple optical sensors, each detecting different portions of the radiation beam (reflected, scattered, and other portions). This segmentation allows for more precise measurement of emissivity and surface roughness by analyzing different radiation components separately, thereby improving measurement precision while managing device complexity through modular sensor arrangement
Solution Approach 2:
A processing device acts as an intermediary between the multiple optical sensors and the measurement results. The processing device receives data from multiple sensors, performs computations to determine emissivity and surface roughness, and outputs the final measurements. This intermediary approach enables accurate measurements while keeping the system manageable by centralizing the complexity in software processing rather than hardware complexity
2Measurement precision
If conventional radiation sources are used, then the device complexity is lower, but the measurement precision deteriorates due to weaker radiation beams and higher noise sensitivity
Solution Approach 1:
The system changes the parameter of radiation beam intensity by using a stronger, more focused radiation beam compared to conventional systems. This increased intensity improves the signal-to-noise ratio and enables more precise surface roughness measurements. The focused beam also allows better control over the illuminated region, further enhancing measurement precision without excessive energy consumption
3Productivity
If conventional systems without focused beams are used, then the ease of operation is higher, but the productivity deteriorates due to slower measurement processes
Solution Approach 1:
The system achieves multi-functionality by using a single focused radiation beam and multiple optical sensors to simultaneously determine both emissivity and surface roughness of the target. This universal approach allows the system to perform multiple measurements in parallel, significantly improving productivity and measurement speed while maintaining ease of operation through automated data processing
