Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If trial-and-error methodology is used to determine switch plan settings, then the desired efficiency can be achieved, but the process becomes time consuming and causes energy losses during analysis
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing voltage dependence characteristics for different load conditions and capacitor bank configurations before actual operation. When a switch plan is needed, the pre-computed data is directly retrieved and applied, eliminating the need for time-consuming trial-and-error analysis during actual power delivery optimization.
2Loss of energy
If voltage regulation algorithms continuously adjust settings to optimize efficiency, then energy losses are reduced, but system complexity increases
Solution Approach 1:
The patent segments the voltage regulation problem by pre-computing and storing voltage dependence characteristics for different load conditions and capacitor bank configurations in separate data structures. This segmentation allows the system to retrieve pre-computed solutions rather than performing complex real-time calculations, reducing system complexity while maintaining energy optimization capabilities.
3Productivity
If capacitor banks are activated and deactivated to optimize power flow, then system efficiency improves, but the trial-and-error process increases time consumption
Solution Approach 1:
The patent applies preliminary action by pre-calculating the optimal capacitor bank configurations and their corresponding voltage dependence characteristics for various load conditions. These pre-computed switch plans are stored and directly applied when needed, eliminating the time-consuming trial-and-error process of activating and deactivating capacitor banks during actual operation while maintaining system efficiency optimization.
