Controller Power Output Control via Data Communication Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices can be affected by external environments, leading to incorrect connection detection and subsequent power supply to unconnected external devices, causing corrosion, charging failures, and overheating due to abnormal connection states.
Innovation Solution
An electronic device with a connection unit and a controller that determines the connection state by checking for data communication possibility through the connection unit, controlling power output based on this determination to prevent unnecessary power supply and potential corrosion.

Engineering Contradiction Analysis
1Reliability
If the electronic device supplies power to an external electronic device through the connection unit without verifying data communication capability, then power can be supplied to connected devices, but corrosion of the connector and overheating may occur when the external device is not actually connected
Solution Approach 1:
The electronic device performs data communication verification through the connection unit before supplying power to the external electronic device. This preliminary check determines whether the external device is actually connected, preventing power supply to unconnected devices and thereby avoiding connector corrosion and overheating issues
Solution Approach 2:
The system establishes a feedback mechanism where the controller continuously monitors data communication status through the connection unit. Based on this feedback information, the power supply is dynamically controlled - enabling power when communication is successful and disabling it when communication fails or is not established, thus preventing harmful effects
2Object-affected harmful factors
If the electronic device checks data communication capability before power supply, then connector corrosion is prevented, but the device complexity increases due to additional control mechanisms
Solution Approach 1:
The connection unit serves multiple functions: it enables both data communication verification and power supply control. By making the connection unit multi-functional, the system avoids adding separate dedicated verification hardware, thus preventing connector corrosion while minimizing the increase in overall device complexity
Solution Approach 2:
The controller utilizes the existing communication interface and protocols to perform self-verification of the connection state. The system serves itself by using its own communication capabilities to detect connection status and automatically control power supply accordingly, eliminating the need for additional external verification devices
