Engineering Contradiction Analysis
1Measurement precision
If manual calibration is used for thermal management systems with unique configurations, then calibration accuracy can be achieved, but calibration time and resource consumption increase significantly
Solution Approach 1:
The thermal management system performs self-calibration by automatically determining pump calibration values based on measured fluid flow rates and operating conditions. The processing circuitry compares measured flow rates with expected flow rates from maps and iteratively adjusts pump calibration values without requiring manual intervention, enabling the system to calibrate itself efficiently.
Solution Approach 2:
The system changes the calibration parameters of the pump by adjusting pump calibration values in an iterative process. The processing circuitry modifies these parameters based on the difference between measured and expected fluid flow rates, allowing the system to adapt to unique configurations automatically.
2Reliability
If manual calibration is performed for each unique configuration, then system performance can be optimized, but resource consumption and complexity increase
Solution Approach 1:
The system automatically determines pump calibration values by measuring fluid flow rates and comparing them with expected values from pre-stored maps. This self-calibration process eliminates the need for manual calibration procedures and external verification, reducing calibration complexity while maintaining system performance.
Solution Approach 2:
The processing circuitry uses feedback from measured fluid flow rates to adjust pump calibration values. By continuously monitoring the difference between measured and expected flow rates, the system iteratively refines calibration parameters, ensuring optimal performance without increasing operational complexity.
3Productivity
If pre-defined configurations are used for thermal management systems, then installation time is reduced, but adaptability to unique configurations is lost
Solution Approach 1:
The system maintains adaptability to unique configurations by automatically determining pump calibration values based on measured fluid flow rates and operating conditions. The processing circuitry adjusts calibration parameters iteratively, allowing the system to adapt to any configuration while keeping installation time short.
Solution Approach 2:
The system uses pre-stored maps of expected fluid flow rates as a foundation for calibration. These preliminary data provide a starting point that speeds up the calibration process, while the subsequent iterative adjustment based on actual measurements ensures adaptability to unique configurations.
