Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a temperature sensor is mounted on the board to measure shutter temperature, then the measurement process becomes feasible, but the measurement precision deteriorates due to temperature difference between board and shutter
Solution Approach 1:
The patent introduces a mathematical model as an intermediary to bridge the gap between board temperature measurement and shutter temperature. The model uses the relationship between board temperature and shutter temperature, incorporating temperature difference compensation, to derive the actual shutter temperature from the board temperature measurement without requiring direct contact with the shutter.
Solution Approach 2:
The patent changes the measurement parameter from direct shutter temperature to board temperature, and then transforms this parameter through mathematical modeling and compensation calculations to obtain the accurate shutter temperature. This parameter transformation allows indirect measurement while maintaining precision.
2Productivity
If noise is present in the temperature measurement system, then the measurement process continues, but the measurement precision deteriorates due to noise-induced errors
Solution Approach 1:
The patent implements feedback mechanisms through multiple measurements and iterative corrections. The system performs initial measurements, calculates temperature differences, applies corrections based on noise analysis, and iterates until convergence, thereby continuously improving measurement precision while maintaining operational continuity.
Solution Approach 2:
The patent converts noise into a useful signal for calibration. By analyzing noise characteristics and using them to determine correction factors, the system transforms noise-induced errors into improved measurement accuracy through statistical processing and correction algorithms.
