Power Supply Control for Cable Authentication Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply apparatuses prolong authentication communication time by stopping and responding to external device requests during the process, which delays the completion of authentication.
Innovation Solution
A power supply apparatus with a control unit that performs authentication communication with a cable after connection and refuses external requests until the authentication is completed, prioritizing the communication to shorten the authentication time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power supply apparatus stops authentication communication to respond to external device requests, then the apparatus can handle external requests, but the authentication communication time is prolonged
Solution Approach 1:
The power supply apparatus performs authentication communication with the cable before accepting or responding to any external device requests. By completing the authentication process in advance, the system ensures that subsequent request handling does not interrupt or delay authentication, thus resolving the contradiction between handling requests and maintaining fast authentication.
2Productivity
If the power supply apparatus accepts requests during authentication communication, then the apparatus can serve external devices, but the authentication process is delayed
Solution Approach 1:
The system prioritizes authentication communication by completing it before processing external device requests. This preliminary action ensures that the authentication process finishes without being interrupted by request handling, thereby maintaining both service productivity and fast authentication completion.

AI summary
A power supply apparatus includes a communication unit and a control unit. The control unit controls the communication unit so as to perform authentication communication with a cable after the cable is connected to the power supply apparatus, and controls the communication unit so as not to accept a request from an external apparatus connected to the cable in a period until the authentication communication is completed.
