Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods are used to design reset switch power supply, then the power supply can operate, but the circuit becomes complex, cost increases, and efficiency decreases
Solution Approach 1:
The power supply control system is segmented into distinct functional modules: detection circuits for monitoring system status, a main controller for decision-making, and a switch circuit for power control. This segmentation allows each module to perform its specific function independently, simplifying the overall circuit design while maintaining reliable operation.
Solution Approach 2:
A main controller is introduced as an intermediary between the detection circuits and the switch circuit. This intermediary processes detection signals, determines system status, and generates appropriate control signals, thereby simplifying the control logic and reducing direct complexity between detection and switching components.
2Measurement precision
If conventional detection systems are used, then system status can be monitored, but coordination between main controller and detection systems is poor, making accurate shutdown difficult
Solution Approach 1:
Detection circuits continuously monitor system status and provide feedback signals to the main controller. The main controller uses this feedback to accurately determine system status and generate appropriate shutdown control signals, improving both detection precision and coordination ease through a closed-loop control mechanism.
