Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual data collection and mapping methods are used to restore single object mapping in digital space, then the mapping can be achieved according to actual situation on spot, but the process becomes time-consuming and laborious
Solution Approach 1:
The patent uses digital twin technology to create virtual copies of physical equipment and their relationships. Instead of manually collecting and mapping data for each object, the system automatically generates digital replicas that mirror the physical environment, including equipment locations, power supply paths, and spatial relationships, thereby eliminating time-consuming manual data collection while maintaining mapping accuracy
Solution Approach 2:
The patent replaces manual mechanical data collection processes with automated digital systems. The digital twin platform automatically captures, processes, and updates equipment information and power supply path data through digital means, substituting the manual mechanical approach of field survey and paper-based recording with efficient digital automation
2Adaptability or versatility
If manual mapping of single objects is performed in digital space, then individual equipment can be represented, but linkage display between equipment is lacking
Solution Approach 1:
The patent merges individual equipment digital twins into a unified digital twin system that automatically establishes and displays linkage relationships. The system combines equipment data, spatial positions, and power supply path information into an integrated model, enabling automatic linkage display between equipment without requiring complex manual configuration of relationships between individual objects
Solution Approach 2:
The digital twin platform provides universal functionality that automatically handles multiple aspects of equipment representation and relationship mapping. A single digital twin system simultaneously manages equipment identification, spatial positioning, power supply path tracing, and linkage display, eliminating the need for separate systems for each function and reducing overall system integration complexity
3Reliability
If conventional digital twin construction with manual modeling is used, then on-site demands can be met, but it is difficult to determine fault nodes and impact scope during equipment abnormalities
Solution Approach 1:
The patent implements feedback mechanisms where the digital twin system continuously monitors equipment status and automatically traces power supply paths when abnormalities occur. The system provides real-time feedback by highlighting affected equipment and power paths, enabling operators to quickly identify fault nodes and impact scope without manual investigation, thereby improving both reliability and ease of operation in fault diagnosis
Solution Approach 2:
The system performs preliminary action by pre-establishing complete power supply path mappings and equipment linkage relationships in the digital twin model before faults occur. When equipment abnormalities are detected, the system can immediately trace and display affected paths using the pre-built digital model, eliminating the need for time-consuming manual fault analysis and improving both diagnostic reliability and operational ease
