Engineering Contradiction Analysis
1Device complexity
If a regulator circuit module is designed with fixed electrical parameters to meet most usage requirements, then the device complexity is reduced and ease of manufacture is improved, but the performance to keep output voltage stable under different load conditions deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the regulator circuit adaptable to different load conditions. The regulator circuit includes a compensating circuit that can be dynamically activated or deactivated based on the operating conditions. This allows the circuit to change its compensation characteristics dynamically, improving output voltage stability across varying load conditions without requiring multiple fixed-parameter circuits.
Solution Approach 2:
The patent implements parameter changes by modifying the compensation parameters of the regulator circuit based on load conditions. The compensating circuit changes its effective parameters (such as compensation capacitance or resistance) depending on whether it is activated, allowing the regulator to optimize its performance for different operating scenarios while using a single unified circuit structure.
2Reliability
If a compensating circuit is added to dynamically adjust the output voltage, then the output voltage stability under different load conditions is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing the compensating circuit to serve multiple functions. The same compensating circuit can provide different levels of compensation depending on its activation state, allowing a single circuit element to address multiple performance requirements across different operating conditions, thereby reducing the need for separate circuits for different scenarios.
Solution Approach 2:
The regulator circuit implements self-service through its feedback mechanism. The feedback circuit automatically detects the output voltage status and load conditions, and based on this information, the control circuit automatically activates or deactivates the compensating circuit without external intervention. This self-regulating mechanism improves voltage stability while minimizing the need for complex external control systems.
