Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual event log operations are analyzed separately, then detailed operation records are obtained, but it becomes difficult to understand overall operator intentions and patterns
Solution Approach 1:
The patent combines multiple individual event log operations into grouped operation sequences that represent complete operator intentions. By merging related operations that occur within a time window and involve the same device or process, the system preserves detailed operation records while simultaneously presenting consolidated views of operator intentions, thus resolving the contradiction between detailed analysis and overall pattern understanding.
Solution Approach 2:
The patent introduces a temporal dimension by organizing operations into time-based sequences and grouping them according to their temporal relationships. This dimensional transformation allows the system to maintain detailed operation data while presenting aggregated views that reveal operator intentions across time, enabling both precise individual operation analysis and comprehensive pattern recognition.
2Reliability
If detailed operating procedures are documented in SOP, then operation quality can be standardized, but flexibility for handling unique situations is reduced
Solution Approach 1:
The patent implements feedback mechanisms that capture actual operator operations and use them to refine and update standard operating procedures. By continuously analyzing real operation data and comparing it with documented SOPs, the system identifies gaps and improvements, allowing SOPs to evolve while maintaining operational standards. This feedback loop enables both consistency through documented procedures and adaptability through continuous improvement based on actual practice.
3Manufacturing precision
If multiple operations are performed to adjust process values gradually, then precise control is achieved, but analysis complexity increases
Solution Approach 1:
The patent segments the analysis process into distinct levels: individual operation detection, operation grouping by device and time window, and sequence formation based on temporal relationships. This hierarchical segmentation allows the system to handle multiple granular operations for precise process control while managing analysis complexity through structured organization, where each segmentation level processes data at an appropriate granularity without overwhelming the overall system.
