Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If signal acquisition is performed continuously from time series outputs, then complete signal data is obtained, but the accuracy of subsequent processing deteriorates due to timing variations
Solution Approach 1:
The determination part预先 determines the optimal timing for signal acquisition based on preset conditions before actually acquiring the target signal. This preliminary timing determination ensures that signals are captured at the most appropriate moments, resolving the contradiction between continuous acquisition and accurate processing by proactively selecting optimal acquisition instances.
Solution Approach 2:
The system uses feedback mechanisms where the determination part continuously monitors signal characteristics and adjusts acquisition timing based on preset conditions. This feedback loop ensures that signal acquisition timing is dynamically optimized, maintaining both measurement precision and processing reliability by adapting to real-time signal variations.
2Ease of operation
If signal recording is performed at fixed intervals, then the system operation is simple, but the accuracy of target signal acquisition deteriorates due to mismatched timing
Solution Approach 1:
The system transitions from static fixed-interval recording to dynamic condition-based recording. The determination part evaluates preset conditions dynamically and adjusts recording timing accordingly, allowing the system to maintain operational simplicity while significantly improving target signal acquisition accuracy through adaptive timing selection.
Solution Approach 2:
The system changes the timing parameter from fixed intervals to variable intervals determined by preset conditions. This parameter change allows recording to occur at optimal moments based on signal characteristics, resolving the contradiction between operational simplicity and acquisition accuracy by making timing flexible rather than rigid.
