Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the actual vibration attribute curve is directly used for evaluation, then the evaluation process is simple, but the accuracy of the evaluation result is low due to time difference errors
Solution Approach 1:
The patent applies preliminary action by correcting the actual vibration attribute curve before evaluation. Specifically, the system determines delay durations at transformation points in advance, uses these to correct the actual curve to obtain a corrected curve, and then performs evaluation based on the corrected curve. This preliminary correction step eliminates time difference errors before they affect the evaluation accuracy.
Solution Approach 2:
The patent applies segmentation by dividing the vibration attribute curve into multiple segments based on transformation points. The system identifies N transformation points on the actual vibration attribute curve, segments the curve accordingly, and determines delay duration for each segment. This segmentation allows precise correction of time differences at each segment while maintaining overall curve accuracy.
2Measurement precision
If delay correction is applied to the actual vibration attribute curve, then the accuracy of curve deviation information is improved, but the complexity of the processing increases
Solution Approach 1:
The system performs preliminary determination of delay durations at transformation points before calculating curve deviation. By pre-calculating the delay duration for each transformation point and applying corrections in advance, the system ensures that the curve deviation information is based on accurate, time-synchronized data, thereby improving measurement precision.
Solution Approach 2:
The patent applies local quality by focusing correction efforts on transformation points rather than uniformly correcting the entire curve. The system identifies specific transformation points where time differences occur, determines delay durations locally at these points, and applies corrections segment-by-segment. This localized approach improves accuracy where it matters most while avoiding unnecessary processing elsewhere.
3Measurement precision
If multiple transformation points are used for delay determination, then the correction accuracy is improved, but the computational complexity increases
Solution Approach 1:
The patent segments the vibration attribute curve into multiple segments based on N transformation points. Each segment is independently analyzed to determine its specific delay duration. This segmentation allows the system to capture local variations in delay across different parts of the curve, improving overall correction accuracy while managing computational complexity through structured processing.
Solution Approach 2:
The system applies local quality by determining delay duration specifically at each transformation point rather than using a single global delay value. Each transformation point's delay duration is calculated based on local curve characteristics, ensuring high accuracy for that specific segment. This localized determination method improves precision without requiring excessive computational resources across the entire curve.
