Wireless Charging Authentication Protocol for Secure Billing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless charging protocols lack authentication mechanisms, preventing businesses from billing customers for wireless charging services in public areas, as they do not account for authentication processes.
Innovation Solution
A method and system for wireless charging authentication, where a wireless charging device communicates with a portable electronic device to verify authentication information, such as a security code or unique ID, before initiating or stopping power transfer, using in-band or out-of-band communication channels, and includes processes for handling authentication failures and sending alerts or messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless charging protocols are implemented without authentication mechanisms, then power charging functionality is provided, but billing capability is lost
Solution Approach 1:
The patent applies preliminary action by implementing authentication mechanisms before power charging begins. The system performs authentication procedures in advance to verify user identity and charging eligibility, ensuring that billing information is captured before the charging process starts. This resolves the contradiction by maintaining ease of operation while preventing loss of billing capability through pre-authorization.
Solution Approach 2:
The patent introduces an intermediary authentication module that mediates between the power charging system and billing system. This intermediary component handles authentication verification and information exchange, allowing the charging system to maintain operational simplicity while the intermediary ensures billing information is properly captured and transmitted for commercial transactions.
2Loss of information
If authentication mechanisms are added to wireless charging protocols, then billing capability is enabled, but protocol complexity increases
Solution Approach 1:
The patent applies universality by designing an authentication mechanism that serves multiple functions simultaneously. The authentication process not only verifies user identity for billing purposes but also validates charging eligibility, manages power transfer authorization, and ensures system security. This multi-functionality reduces overall system complexity compared to having separate dedicated systems for each function.
Solution Approach 2:
The patent merges authentication functions with existing wireless charging protocol operations. Rather than creating entirely separate authentication and billing systems, the patent integrates authentication verification into the existing power transfer negotiation and control procedures, combining multiple functions into unified protocol steps that reduce overall system complexity.
3Adaptability or versatility
If existing wireless charging protocols are used without modification, then compatibility is maintained, but authentication functionality is absent
Solution Approach 1:
The patent applies the nested doll principle by embedding authentication procedures within the existing wireless charging protocol structure. The authentication mechanisms are nested inside the standard power transfer protocol sequences, allowing authentication functionality to be incorporated without disrupting external protocol compatibility. The nested authentication steps operate within the existing protocol framework while adding the required verification capabilities.

AI summary
A method of wireless charging authentication for a wireless charging device includes receiving an authentication information from an electronic device for authentication of charging; determining whether the authentication succeeds or not according to the authentication information; and supplying wireless power to the electronic device for charging if the authentication succeeds or stopping to supply wireless power to the electronic device if the authentication fails.
