Solution Overview
Problem
The existing wireless power supply systems require an electronic device for testing in the factory, which is inconvenient and time-consuming, as authentication between the power supply apparatus and the device needs to be performed, prolonging the testing process of the power supply apparatus's wireless power supply capability.
Innovation Solution
A power supply apparatus with a power supply unit that outputs both communication and power supply power, a communication unit for wireless communication, and a control unit that manages power output in test modes to efficiently test the apparatus without the need for an external device, allowing for reduced testing time and efficient authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication process is performed between power supply apparatus and electronic device for testing, then wireless power supply capability can be verified, but testing time is prolonged
Solution Approach 1:
The patent creates a virtual electronic device that replicates the authentication and power reception functions of a real electronic device. This virtual copy allows the power supply apparatus to complete the authentication process and verify wireless power supply capability without requiring physical presence of actual testing devices, thereby reducing testing time while maintaining verification reliability
Solution Approach 2:
The power supply apparatus performs self-testing by using its own communication unit to simulate the electronic device's response during authentication. The control unit configures the apparatus to test itself by generating test signals and evaluating the authentication process internally, eliminating the need for external testing devices and reducing testing time
2Reliability
If external electronic device is required for testing, then accurate wireless power supply capability can be tested, but testing convenience is reduced
Solution Approach 1:
The power supply apparatus is configured to perform self-diagnosis and self-testing functions. The control unit enables the apparatus to generate test signals, simulate authentication processes, and evaluate its own wireless power supply capability without requiring external testing equipment or personnel intervention, thereby improving testing convenience while maintaining accuracy
Solution Approach 2:
The communication unit and control unit are designed to serve dual purposes: normal operation for wireless power supply and authentication, plus testing and self-diagnosis functions. This multi-functionality allows the same hardware to perform both operational tasks and verification tasks, eliminating the need for separate testing equipment and improving convenience
