Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional voltage estimation systems are used, then voltage measurement is possible, but maintenance is difficult and costly requiring expert workers and element shutdown
Solution Approach 1:
The patent introduces a capacitor network as an intermediary between the live element and measurement devices. This capacitor divider circuit allows voltage estimation to be performed on live elements without requiring expert workers or system shutdown, as the capacitors provide electrical isolation and enable safe measurement through voltage division ratios
Solution Approach 2:
The patent replaces traditional direct electrical connection methods with a capacitor-based measurement system. Instead of using direct conductive paths that require shutdown for safety, the system uses capacitive coupling to achieve voltage measurement on live elements, eliminating the need for mechanical intervention and expert workers
2Measurement precision
If traditional voltage estimation systems are used, then initial measurement capability is provided, but measurement precision cannot be maintained over time due to component aging
Solution Approach 1:
The patent incorporates feedback mechanisms where the measured voltage values are used to continuously monitor and adjust the system performance. By measuring voltages across the capacitor network and calculating based on known capacitance ratios, the system can detect drift due to aging and compensate for it, maintaining measurement precision over extended operational periods
Solution Approach 2:
The patent uses changes in electrical parameters (voltage division ratios across different capacitors) to detect and compensate for aging effects. By monitoring how the voltage distribution changes across the capacitor network over time, the system can adjust measurement calculations to maintain accuracy despite component degradation
3Ease of repair
If maintenance operations are performed on traditional systems, then repairs can be made, but only when the element is not live and only by expert workers
Solution Approach 1:
The capacitor network serves as an intermediary that enables safe operation and maintenance on live elements. The capacitive coupling provides electrical isolation that protects workers from direct exposure to high voltages, allowing maintenance to be performed on live systems without requiring shutdown or specialized expert intervention
