Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current NFC wireless charging technology poses security risks due to the lack of authentication mechanisms, which can lead to unauthorized charging and potential privacy breaches.
Innovation Solution
An NFC wireless charging method that includes an authentication process between the power supply device and the device to be charged, where an NFC connection is established, an authentication request is sent, and if the authentication is successful, the power supply device converts its electric quantity into the device to be charged, enabling secure charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If NFC wireless charging technology is implemented without authentication mechanism, then charging convenience is improved, but security is worsened
Solution Approach 1:
The patent implements authentication before the charging process begins. The power supply device and device to be charged perform mutual authentication through NFC communication before establishing the charging connection, ensuring that only authorized devices can receive power. This preliminary security check prevents unauthorized charging while maintaining convenience for legitimate users.
2Reliability
If authentication process is added to NFC wireless charging, then security is improved, but device complexity is worsened
Solution Approach 1:
The patent utilizes the existing NFC communication capability of mobile devices to perform authentication functions. The same NFC hardware that enables contactless payment and data exchange is leveraged for authentication during wireless charging, eliminating the need for separate authentication hardware and minimizing additional system complexity.
3Reliability
If authentication process is added to NFC wireless charging, then security is improved, but charging time is worsened
Solution Approach 1:
The authentication process is designed to complete rapidly through efficient NFC communication protocols. The mutual authentication exchange between power supply device and device to be charged is optimized to occur in minimal time during the initial connection phase, so that the actual charging can begin without significant delay.
