Power Supply Authentication Message Handling for Operation Limiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices that do not support authentication communication with power supply devices may experience limited power supply, leading to incomplete or interrupted operation.
Innovation Solution
An electronic device equipped with a communication unit to detect predetermined authentication messages from a power supply device, and a control unit that limits the device's operation when such messages are received.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power supply device performs authentication communication to limit power supply, then power supply security is improved, but electronic devices that do not support authentication communication cannot operate as desired
Solution Approach 1:
The patent introduces a message transmission mechanism as an intermediary between the power supply device and electronic devices. The power supply device sends a predetermined message through the communication unit to indicate authentication status. This intermediary message system allows the power supply device to convey power limitation information without requiring the electronic device to support complex authentication communication protocols, thus maintaining compatibility while ensuring power supply security.
2Reliability
If the electronic device limits operation when authentication fails, then power supply security is maintained, but device functionality is reduced
Solution Approach 1:
The patent applies partial action by implementing selective operation limitation. Instead of completely shutting down the device when authentication fails, the control unit limits only specific operations that would exceed power supply capabilities. The device continues to operate with reduced functionality, allowing users to still access essential features while preventing power supply issues. This partial limitation approach maintains power supply security while preserving ease of operation for critical functions.

AI summary
An electronic device includes a control unit and a communication unit that is capable of communicating with a power supply device. The control unit determines whether or not a predetermined message relating to an authentication communication is received from the power supply device via the communication unit, and controls the electronic device to limit operation of the electronic device in a case where the predetermined message is received from the power supply device via the communication unit.
