Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If feedback control based on current temperature is used, then the control system is simple, but the response to external temperature changes is delayed
Solution Approach 1:
The control device performs preliminary cooling action before the in-vehicle device temperature actually rises by detecting external temperature changes and predicting future temperature increases. This allows the cooling device to start operating in advance, eliminating the delay inherent in feedback control while maintaining system simplicity.
2Reliability
If cooling is performed after temperature changes are detected, then the control logic is simple, but sufficient cooling cannot be performed
Solution Approach 1:
The system performs preliminary cooling by detecting external temperature changes and predicting that the in-vehicle device temperature will rise. The cooling device is activated before the temperature actually increases, ensuring sufficient cooling effectiveness without requiring complex real-time control logic.
3Use of energy by moving object
If feedback control is used, then the control device is simple, but cooling power increases
Solution Approach 1:
By performing preliminary cooling based on external temperature change detection, the system prevents large temperature increases from occurring. This allows the cooling device to operate at lower power levels for longer periods rather than requiring high-power intermittent operation, reducing overall energy consumption while maintaining simple control logic.
