Wireless Power Authentication Reset to Prevent Protocol Data Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless power transfer systems face challenges in efficiently managing authentication protocols between wireless power transmitters and receivers, particularly in restarting the authentication process when issues arise, which can lead to data mixing and confusion between the existing and restarted protocols.
Innovation Solution
Incorporating a communication/control circuit in both wireless power transmitters and receivers to perform an authentication protocol that includes sending and receiving authentication request and response messages, as well as reset messages to restart the authentication process when necessary, thereby allowing immediate protocol restarts and preventing data mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the authentication protocol is restarted when issues occur, then the system can recover from authentication failures, but data mixing and confusion may occur between existing and restarted protocols
Solution Approach 1:
The system performs preliminary actions by saving the original authentication data (request and response messages) before restarting the authentication protocol. This allows the system to preserve the original data state and prevent data mixing between the existing and restarted protocols, while still enabling recovery from authentication failures.
Solution Approach 2:
The system creates a copy of the original authentication data before protocol restart. By storing the original authentication request and response messages, the system can restore the authentication state after restart, preventing data loss and mixing while maintaining reliability through the ability to recover from failures.
2Loss of information
If authentication data is saved before protocol restart, then data mixing is prevented, but additional memory usage and complexity increase
Solution Approach 1:
The system performs the data saving action preliminarily, before the protocol restart is triggered. By storing the original authentication data at the point of detecting protocol issues, the system prevents data mixing without requiring complex ongoing management during the protocol execution, thus reducing overall system complexity.
3Productivity
If the authentication protocol is restarted immediately, then operational efficiency is improved, but data confusion may occur
Solution Approach 1:
The system performs the critical action of saving original authentication data immediately before restarting the protocol. This preliminary data preservation enables immediate protocol restart for efficiency while preventing data confusion, as the original data is already secured and cannot be mixed with the restarted protocol data.
