Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the auxiliary power supply uses a conventional charging method for the capacitor array, then the system structure remains simple, but the charge speed is slow and cannot quickly provide auxiliary power when external power is interrupted
Solution Approach 1:
The patent implements periodic discharge and sub-charge operations on the capacitor array. The charging process is divided into multiple cycles where the capacitor is periodically discharged and then recharged, which significantly accelerates the overall charging speed compared to conventional continuous charging methods.
Solution Approach 2:
The patent performs preliminary discharge operations before the final charging phase. By periodically discharging the capacitor array before sub-charge operations, the system prepares the capacitor for faster charging, enabling the auxiliary power supply to quickly reach the required voltage level when external power is restored or provided.
2Reliability
If the auxiliary power supply charges the capacitor array to a high voltage level, then the auxiliary power capacity increases, but the charging time becomes longer and data protection responsiveness decreases
Solution Approach 1:
The periodic discharge and sub-charge cycles enable the capacitor array to quickly reach the target voltage level. This method reduces the total charging time while maintaining sufficient charge capacity to provide reliable auxiliary power for data protection operations when external power is interrupted.
Solution Approach 2:
The patent dynamically adjusts the charging process by periodically interrupting it with discharge operations. This dynamic approach allows the system to optimize the charging speed and reach the required voltage level faster, reducing the time loss while ensuring adequate power capacity for data protection.
