Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If partial overall value is calculated for a partial range of frequencies, then calculation complexity is reduced, but diagnostic accuracy deteriorates
Solution Approach 1:
The frequency range is divided into multiple sub-ranges, and partial overall values are calculated for each sub-range separately. This segmentation allows comprehensive analysis of different frequency components while maintaining manageable calculation complexity for each segment.
Solution Approach 2:
The patent introduces a new dimension of analysis by calculating partial overall values across multiple frequency sub-ranges rather than a single overall value. This multi-dimensional approach enhances diagnostic accuracy by capturing frequency-specific vibration characteristics.
2Measurement precision
If FFT analysis is performed on entire frequency range, then diagnostic accuracy is improved, but calculation time increases
Solution Approach 1:
The frequency spectrum obtained from FFT analysis is divided into multiple sub-ranges, and partial overall values are calculated for each sub-range. This segmentation reduces the computational burden compared to calculating a single overall value across the entire frequency range, while still maintaining comprehensive diagnostic information.
Solution Approach 2:
Instead of calculating the overall value for the entire frequency range, the patent calculates partial overall values for specific sub-ranges. This partial action approach focuses computational resources on relevant frequency bands, reducing calculation time while preserving diagnostic accuracy for specific vibration components.
