Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional diagnostic techniques are used to identify anomaly factors, then diagnostic accuracy is improved, but time consumption and complexity increase
Solution Approach 1:
The system pre-calculates and stores diagnostic rules and factor relationships before actual diagnosis occurs. When an anomaly is detected, the pre-prepared diagnostic framework immediately processes the data, eliminating the need for time-consuming real-time analysis while maintaining high diagnostic accuracy
Solution Approach 2:
The patent replaces manual detailed investigation and mechanical diagnostic procedures with an automated information processing system. The control unit automatically calculates factor probabilities and generates diagnostic results, substituting human analysis with computational algorithms that provide both accuracy and speed
2Reliability
If detailed investigation is performed to identify anomaly factors, then diagnostic completeness is improved, but ease of operation deteriorates
Solution Approach 1:
The diagnostic system performs self-diagnosis automatically without requiring operator intervention for detailed investigation. The control unit independently calculates factor probabilities, identifies anomaly causes, and generates diagnostic reports, making the system self-sufficient while maintaining comprehensive diagnostic coverage
Solution Approach 2:
The system incorporates feedback mechanisms where diagnostic results are automatically processed and used to refine future diagnoses. The control unit continuously learns from operational data, improving both diagnostic completeness and ease of use through automated feedback loops that eliminate manual investigation requirements
