Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional plant maintenance management systems are used, then general maintenance plans can be provided, but customized maintenance execution periods for each instrument cannot be achieved
Solution Approach 1:
The system segments maintenance planning by individual instruments rather than treating the entire plant as a single unit. Each instrument receives customized maintenance execution periods based on its specific characteristics, abnormality history, and operational context, enabling tailored maintenance schedules while managing complexity through modular processing
Solution Approach 2:
The system dynamically adjusts maintenance execution periods by changing key parameters such as maintenance frequency, timing, and scope based on instrument-specific data including abnormality reports, work records, and operational conditions. This allows customization of maintenance schedules without requiring complete system redesign
2Measurement precision
If maintenance plans are customized for each instrument, then maintenance accuracy improves, but processing time increases
Solution Approach 1:
The system performs preliminary actions by pre-processing and storing abnormality reports, work records, and instrument characteristics in a structured database before maintenance planning is needed. This preparation enables rapid retrieval and analysis of historical data when generating customized maintenance plans, reducing actual plan generation time while maintaining high accuracy
Solution Approach 2:
The system creates and maintains copies of historical maintenance data, abnormality reports, and work records in structured formats that can be quickly queried and analyzed. These data copies enable fast comparison and pattern recognition without requiring real-time analysis of original source documents, thus improving plan generation speed while preserving accuracy
3Reliability
If historical abnormality data is analyzed, then maintenance plan quality improves, but data processing complexity increases
Solution Approach 1:
The system extracts only the most relevant features and parameters from historical abnormality data, work records, and instrument information that directly impact maintenance planning. By selecting and focusing on key data elements such as abnormality types, frequencies, and resolutions rather than processing all available data, the system improves plan quality while reducing processing complexity
Solution Approach 2:
The system develops a universal data processing framework that handles multiple types of maintenance data (abnormality reports, work orders, instrument specifications) through standardized processing routines. This multi-functional approach allows the same processing logic to handle diverse data types, reducing overall system complexity while comprehensively analyzing historical data for improved maintenance planning
