Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If devices connected to both ends of an influenced NC are determined to be equally influenced devices, then the fault influence determination is simple, but the accuracy of fault influence determination deteriorates because hierarchical relationships of devices are not taken into consideration
Solution Approach 1:
The patent segments the network devices into different hierarchical ranks (first rank, second rank, third rank, etc.) based on their importance and functionality. This segmentation allows the system to differentiate between critical devices that must be restored first and less critical devices, thereby improving the accuracy of fault influence determination while maintaining operational simplicity through automated rank-based classification.
Solution Approach 2:
The patent applies local quality by assigning different restoration priorities to devices based on their specific ranks and roles in the network. Instead of treating all devices uniformly, the system tailors the restoration strategy to each device's hierarchical position, ensuring that critical infrastructure devices receive prioritized restoration while less critical devices follow standard procedures.
2Device complexity
If redundant configurations are not taken into consideration in fault influence determination, then the determination process is simpler, but the accuracy deteriorates because lower ranked devices may be incorrectly determined as both-side system failure when they are actually running with one-side system
Solution Approach 1:
The patent performs preliminary action by pre-establishing the hierarchical rank information and redundant configuration relationships before faults occur. The system maintains a database of device ranks and redundant partnerships, allowing it to quickly consult this pre-prepared information during fault determination without performing complex real-time analysis, thus maintaining simplicity while improving accuracy.
Solution Approach 2:
The patent implements feedback by continuously monitoring the operational status of devices and comparing it against the predefined redundant configuration relationships. When a fault occurs, the system uses feedback from the status monitoring to determine whether a lower-ranked device should be considered as having one-side or both-side system failure based on whether its higher-ranked redundant partner is still operational.
