USB Power Chip Auto-Restart in Enclosed Power Supply Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing USB power supply chips in enclosed spaces, such as those in walls or car interiors, cannot be manually turned off or restarted due to noise interference, leading to abnormal operation and disrupted power supply.
Innovation Solution
A power supply system with a detection device that monitors the power supply control chip's operation, controlling a switch to disconnect and reconnect power supply when abnormal, allowing the chip to be restarted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the USB chip is placed in an enclosed space (wall or car interior), then the power supply function is accessible and convenient for users, but the power supply control chip cannot be manually turned off or restarted when it malfunctions due to noise interference
Solution Approach 1:
The system implements automatic detection and restart functionality where the detection device monitors the power supply control chip's operation status and automatically triggers the power supply switch to restart the chip when malfunction is detected, eliminating the need for manual intervention in enclosed spaces
Solution Approach 2:
The detection device continuously monitors the operation status of the power supply control chip and provides feedback to the power supply switch, which adjusts the connection between the power supply device and control chip based on the detected status, enabling automatic restart when abnormal operation is detected
2Duration of action of stationary object
If the power supply control chip operates continuously without manual shutdown capability, then the power supply remains always available, but the chip cannot be restarted after abnormal operation due to noise interference
Solution Approach 1:
The detection device continuously monitors the operation status of the power supply control chip and provides feedback to the power supply switch, which adjusts the connection between the power supply device and control chip based on the detected status, enabling automatic restart when abnormal operation is detected
Solution Approach 2:
The system prepares a restart mechanism in advance through the power supply switch that can quickly reconnect the power supply device to the control chip when malfunction is detected, providing a pre-planned solution to restore reliable operation after noise interference or abnormal conditions

AI summary
A power supply system (1) includes an output terminal (2), a power supply control chip (3), a power supply switch (4) and a detection device (5). The power supply control chip (3) is configured to adjust the amount of an input power providing to an electronic device (7) by the power supply device (6). The power supply switch (4) is configured to control the connection between the power supply device (6) and the power supply control chip (3). The detection device (5) is configured to detect whether the power supply control chip (3) operates normally. When the power supply control chip (3) operates abnormally, the detection device (5) controls the connection between the power supply device (6) and the power supply control chip (3) through the power supply switch (4) for restarting the power supply control chip (3). The power supply control chip (3), the power supply switch (4) and the detection device (5) are disposed in an enclosed space (9).
