Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If time axis waveform analysis and frequency axis waveform analysis are performed to determine abnormality, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the complex waveform analysis into distinct time axis analysis and frequency axis analysis components, allowing each to be processed independently and then integrated for comprehensive abnormality determination
Solution Approach 2:
The patent introduces an abnormality determination device as an intermediary that automatically processes the complex analysis results and provides clear abnormality determinations, mediating between the complex analysis processes and the user
2Measurement precision
If specialized knowledge is required for abnormality determination, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The abnormality determination device performs self-service by automatically executing the complex analysis processes and making abnormality determinations without requiring user expertise in waveform analysis or measurement data characteristics
Solution Approach 2:
The system acts as an intermediary that translates complex technical analysis into simple, interpretable results, allowing unskilled users to obtain accurate abnormality determinations without needing specialized knowledge
3Reliability
If comprehensive waveform analysis is performed, then reliability is improved, but loss of time increases
Solution Approach 1:
The system performs preliminary action by continuously monitoring and analyzing waveforms in real-time, maintaining ready-to-use analysis results that can be quickly interpreted when abnormalities occur
Solution Approach 2:
The patent divides the analysis into time axis and frequency axis components that can be processed in parallel, reducing overall analysis time while maintaining comprehensive reliability
