Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual current adjustment is used to correct phase shifting inaccuracies, then phase shifting accuracy can be improved, but debugging time increases significantly
Solution Approach 1:
The system performs automatic phase compensation through the adder unit that self-adjusts the multi-channel currents based on detected phase differences, eliminating the need for manual debugging and achieving both high accuracy and efficiency
Solution Approach 2:
The system implements a feedback mechanism where the adder unit continuously monitors phase differences between channels and automatically adjusts current distribution to maintain accurate phase shifting, resolving the contradiction between precision and time consumption
2Measurement precision
If manual current adjustment is performed to achieve desired phase, then phase shifting accuracy can be improved, but the process becomes complex and uncontrollable
Solution Approach 1:
The adder unit automatically performs current adjustment and phase compensation without manual intervention, simplifying the debugging process while maintaining high phase shifting accuracy through self-regulating multi-channel current control
3Productivity
If multi-channel current differences are not adjusted, then debugging time is reduced, but phase shifting accuracy deteriorates
Solution Approach 1:
The system achieves both high productivity and accuracy by implementing automatic phase compensation where the adder unit self-adjusts multi-channel currents based on real-time phase difference detection, eliminating the trade-off between debugging speed and precision
Solution Approach 2:
Through continuous feedback on phase differences, the system automatically optimizes current distribution across channels, achieving accurate phase shifting without manual debugging while maintaining high debugging efficiency
