Engineering Contradiction Analysis
1Loss of energy
If each regulator is connected to a respective corresponding load in a one-to-one correspondence manner, then the connection structure is simple and fixed, but the regulator cannot operate under optimal efficiency conditions when current magnitude varies
Solution Approach 1:
The patent implements dynamic reconfiguration of regulator-load connections through a switching circuit. The processor dynamically determines which regulator should serve which load based on real-time current magnitude requirements, allowing the system to adapt to varying operational conditions and maintain optimal regulator efficiency rather than being locked into fixed one-to-one connections.
Solution Approach 2:
The patent enables regulators to serve multiple loads and loads to be served by multiple regulators through the switching circuit. This multi-functional connection capability allows any regulator to be dynamically assigned to any load based on efficiency considerations, transforming the rigid one-to-one correspondence into a flexible many-to-many relationship that optimizes energy loss.
2Adaptability or versatility
If regulators are fixedly connected to loads, then the device structure is simple, but the system cannot adapt to varying current requirements and maintain optimal operation conditions
Solution Approach 1:
The system transitions from static fixed connections to dynamic reconfigurable connections. The processor continuously monitors current requirements and dynamically reassigns regulators to loads through the switching circuit, enabling the system to adapt to varying operational conditions while managing the complexity through intelligent control algorithms.
Solution Approach 2:
The switching circuit acts as an intermediary component that decouples the direct fixed connection between regulators and loads. This intermediary layer enables flexible reconfiguration without requiring physical changes to the regulator or load components themselves, managing the complexity by centralizing the reconfiguration logic in the switching circuit controlled by the processor.
