Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single charging voltage is used to charge the charging circuit, then the circuit structure is simple, but the auxiliary power supply cannot maintain sufficient energy levels when capacitance decreases, leading to data loss during sudden power off
Solution Approach 1:
The patent implements dynamic charging voltage adjustment based on real-time capacitance detection. The controller switches between first and second charging voltages depending on the detected capacitance level, transforming a static single-voltage system into a dynamic multi-voltage system that adapts to changing conditions, thereby maintaining reliable data protection without excessive complexity
Solution Approach 2:
The patent changes the voltage parameter of the charging circuit based on capacitance conditions. When capacitance is below a threshold, the system switches from a first charging voltage to a second charging voltage (higher than the first), optimizing energy storage efficiency and ensuring sufficient power for data protection operations during sudden power off events
2Reliability
If the capacitance of the charging circuit is insufficient, then the auxiliary power supply cannot complete backup operations during sudden power off, but increasing capacitance increases component size and cost
Solution Approach 1:
Instead of increasing capacitance component quantity or size, the patent changes the voltage parameter dynamically. By detecting capacitance levels and switching to a higher second charging voltage when capacitance is insufficient, the system achieves reliable backup operations without requiring larger or more numerous capacitor components
Solution Approach 2:
The system performs preliminary detection of capacitance conditions before a sudden power off event occurs. When insufficient capacitance is detected, the controller proactively adjusts the charging voltage to maximize energy storage, ensuring that backup operations can be completed reliably when needed, rather than waiting for failure conditions
3Use of energy by moving object
If multiple charging voltages are implemented based on capacitance detection, then energy storage efficiency is improved, but the control circuit complexity increases
Solution Approach 1:
The patent implements a dynamic control system that adjusts charging voltage based on real-time capacitance detection. The controller monitors capacitance levels and switches between voltage modes accordingly, creating an adaptive energy storage system that optimizes efficiency while maintaining manageable control complexity through systematic decision logic
Solution Approach 2:
The system incorporates feedback through capacitance detection and voltage adjustment. The controller continuously monitors capacitance conditions and provides feedback by adjusting the charging voltage accordingly, creating a closed-loop control system that optimizes energy storage efficiency while maintaining controlled complexity through automated feedback mechanisms
