Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If off-line simulation techniques are used for system design and analysis, then development costs are reduced and design accuracy is improved, but real-time monitoring capability is lost and operational decision-making is delayed
Solution Approach 1:
The patent transforms static off-line simulation into dynamic real-time monitoring by continuously updating the virtual model with live sensor data from the electrical system. The simulation engine operates in real-time to predict system behavior and generate immediate operational recommendations, eliminating the time delay between design analysis and operational decision-making.
Solution Approach 2:
The patent creates a virtual copy of the physical electrical system that mirrors its real-time state through continuous data acquisition. This virtual model allows operators to analyze system behavior, test scenarios, and make informed decisions without affecting the actual system, providing both design accuracy and real-time responsiveness.
2Ease of operation
If manual protective device setting adjustment is performed by technicians, then flexibility in operation is improved, but coordination errors occur and system reliability deteriorates
Solution Approach 1:
The patent implements continuous feedback by monitoring actual protective device settings and comparing them against coordinated values derived from the virtual model. When deviations are detected, the system generates alerts and recommends corrective actions, ensuring coordination is maintained while allowing operational flexibility through informed manual adjustments.
Solution Approach 2:
The system performs preliminary analysis in the virtual model to predict the impact of proposed protective device setting changes before they are implemented in the physical system. This prevents coordination errors by identifying potential issues in advance and providing corrected settings that maintain system reliability.
3Reliability
If system complexity is increased through redundancy for mission-critical facilities, then system reliability is improved, but the difficulty of tracking and correcting failures increases
Solution Approach 1:
The patent introduces a virtual system model as an intermediary that simplifies the analysis of complex redundant systems. The virtual model automatically tracks interdependencies between redundant components, allowing operators to understand failure propagation and correct issues without manually tracing through complex system interactions.
Solution Approach 2:
The patent segments the complex redundant system into manageable virtual representations of individual components and their interrelationships. This segmentation allows operators to isolate and analyze specific failure modes within the redundant structure without being overwhelmed by the overall system complexity.
4Reliability
If real-time data acquisition and virtual model updating are implemented, then predictive maintenance capability is improved and operational costs are reduced, but system complexity and data processing requirements increase
Solution Approach 1:
The patent creates a universal virtual model that serves multiple functions: it represents the physical system structure, acquires and processes sensor data, performs predictive analysis, and generates operational recommendations. This multi-functionality reduces the need for separate complex systems for each function, managing data processing requirements while enhancing predictive maintenance capability.
