Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a thermal camera is used to capture temperature distribution of a moving conveyance object, then temperature data can be acquired during conveyance, but it becomes difficult to accurately track and measure temperature at specific positions of the moving object
Solution Approach 1:
The system divides the conveyance object into multiple measurement areas along the conveyance direction. By segmenting the object into discrete zones, the system can track temperature changes at each segment independently, maintaining measurement accuracy even as the object moves through the heating apparatus.
Solution Approach 2:
The system adds the time dimension to temperature measurement by capturing temperature distributions at multiple time points during conveyance. This transforms a static spatial measurement problem into a spatio-temporal measurement problem, enabling accurate tracking of temperature at specific positions despite object movement.
2Loss of information
If multiple measurement areas are set along the conveyance direction to track temperature changes, then temperature profile can be generated, but data processing complexity increases
Solution Approach 1:
The system extracts temperature data from specific measurement areas along the conveyance direction and separates this data into distinct time-series datasets. By extracting only the relevant temperature information from each measurement area, the system reduces data processing complexity while preserving essential temperature profile information.
Solution Approach 2:
The system pre-defines multiple measurement areas along the conveyance direction before temperature measurement begins. This preliminary setup allows the system to automatically associate temperature data with specific positions and time points, simplifying subsequent data processing and profile generation.
3Measurement precision
If time-series temperature data is generated for multiple measurement areas, then accurate temperature profile can be obtained, but measurement and detection difficulty increases
Solution Approach 1:
The system segments the conveyance object into multiple fixed measurement areas along the conveyance direction. This segmentation allows the thermal camera to capture temperature data from predetermined zones, making it easier to track and measure temperature changes at each segment without the complexity of tracking individual moving features.
Solution Approach 2:
The system introduces the time dimension by capturing temperature distributions at multiple time points as the object moves. This spatio-temporal approach allows the system to generate time-series data for each measurement area, improving temperature profile accuracy by capturing transient temperature changes during conveyance.
