Innovation Solution
An electronic device with a connector, power supply circuit, discharge circuit, and processor that controls electrical connections to perform first and second discharges to ensure the voltage of the external device is equal to or less than a designated voltage, using a discharge circuit for a designated time and then switching to supply power through a power supply circuit to facilitate communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the discharge circuit discharges the voltage stored in the capacitor of the power stage, then the voltage of the external electronic device drops to a designated level, but the discharge time is slow causing communication failures
Solution Approach 1:
The patent divides the discharge process into multiple stages using different discharge circuits. The first discharge circuit performs rapid initial discharge to quickly reduce voltage to a safe level, while the second discharge circuit completes the discharge process to ensure voltage drops below a predetermined threshold. This segmentation resolves the contradiction by achieving both fast discharge (improving time loss) and complete discharge (maintaining communication reliability).
Solution Approach 2:
The first discharge circuit performs preliminary discharge action before the second discharge circuit takes over. By pre-discharging the capacitor to a safe voltage level quickly, the system prevents communication failures while minimizing the overall discharge time. This preliminary action resolves the contradiction by addressing the most critical time-sensitive portion of the discharge process first.
2Adaptability or versatility
If the power source is reset by discharging the capacitor voltage, then the external electronic device can be reconnected, but the slow discharge process causes malfunctions before reconnection
Solution Approach 1:
The patent segments the voltage discharge process into two distinct phases handled by different discharge circuits. The first discharge circuit rapidly reduces voltage to prevent malfunctions during the critical reconnection window, while the second discharge circuit ensures complete discharge for safe power source reset. This segmentation maintains both reconnection capability and operational reliability.
Solution Approach 2:
The first discharge circuit acts as an intermediary that quickly brings the capacitor voltage to a safe intermediate level, enabling safe reconnection. The second discharge circuit then completes the discharge process. This intermediary approach resolves the contradiction by providing a safe transition state that enables reconnection while preventing malfunctions.
