Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a backup power supply is used to maintain detection during power failures, then fault detection capability is improved, but hardware complexity and configuration complexity increase
Solution Approach 1:
The patent extracts the power storage function from the main power supply system by introducing a separate supercapacitor circuit. This independent power storage component can be independently controlled to power the detection circuit during main power failure, avoiding the need for complex backup power supply systems while maintaining fault detection capability.
Solution Approach 2:
The supercapacitor circuit is pre-charged during normal operation when the main power supply is functional. When power failure occurs, the pre-stored energy in the supercapacitor immediately activates the detection circuit, enabling rapid fault detection without waiting for backup power supply activation or system reboot.
2Duration of action of stationary object
If complex hardware and software structures are configured for backup power, then power continuity is improved, but maintenance time and operational complexity increase
Solution Approach 1:
The detection circuit is designed to be self-activatable during power failure through the supercapacitor circuit. The system automatically detects voltage drops and activates the detection function without requiring manual intervention or complex software configuration, enabling maintenance personnel to quickly identify faults without spending time on system reconfiguration or reboot procedures.
3Device complexity
If traditional error message recording is used without dedicated detection circuit, then system simplicity is maintained, but fault location identification capability deteriorates
Solution Approach 1:
The patent introduces an intermediary detection circuit that acts as a bridge between the power supply system and the storage devices. This detection circuit includes voltage detection units and detection units that can identify abnormal states of storage devices during power failure, providing specific fault location information without requiring complex system structures or manual troubleshooting.
