Wireless Power Reception Authentication for Heat-Aware Power Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless power transmission systems experience unnecessary processing delays due to unrecognized validity of target apparatus during authentication, impairing convenience.
Innovation Solution
A power receiving apparatus and transmitting apparatus are designed to perform device authentication, where successful earlier authentication allows subsequent authentication, and unsuccessful authentication limits power transmission to prevent excessive heat generation by reducing power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If device authentication is performed to enhance security, then reliability is improved, but loss of time increases due to unnecessary processing when validity is not recognized
Solution Approach 1:
The system performs a preliminary validity check on authentication results before initiating subsequent authentication processing. The control unit determines whether the target apparatus is valid based on the first authentication result, and only proceeds with the second authentication if the target is valid. This preliminary determination prevents unnecessary processing time while maintaining security requirements.
2Reliability
If authentication processing is performed between power transmitting and receiving apparatus, then reliability is improved, but device complexity increases
Solution Approach 1:
The authentication system is segmented into two distinct authentication processes: a first authentication between the power transmitting apparatus and a intermediate entity, and a second authentication between the power transmitting apparatus and the target power receiving apparatus. This segmentation allows the system to manage complexity by dividing authentication into modular, manageable stages with clear validity determination points between them.
3Productivity
If power transmission continues without validating authentication results, then productivity is maintained, but object-generated harmful factors increase due to excessive heat generation
Solution Approach 1:
The control unit implements a feedback mechanism that continuously monitors authentication results and adjusts power transmission accordingly. When the first authentication indicates the target apparatus is not valid, the control unit immediately stops or limits power transmission, preventing excessive heat generation. This feedback loop ensures productivity is maintained only when authentication validates safe operation.

AI summary
A power receiving apparatus 200 wirelessly receives power from a power transmitting apparatus 100, mutually performs device authentications with the power transmitting apparatus 100, and determines content related to power reception on the basis of a result of a performed device authentication. The apparatus 200 is capable of performing control such that in response to success in an earlier performed device authentication among the authentications, another device authentication among the authentications is performed, and performing control such that in response to failure in the earlier performed device authentication, said another device authentication is not performed.
