Power Receiving Apparatus Battery Authentication Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery authentication methods fail to notify users of detailed reasons why a non-genuine battery cannot be charged, as they only provide simple notifications, such as LED indicators, without explaining the underlying cause.
Innovation Solution
A power receiving apparatus and method that requests a power transmission apparatus to transmit first power for battery authentication, determines if the battery is genuine, and if not, requests second power to notify the user through a display unit with detailed information, such as 'battery authentication failed', using the second power transmitted from the power transmission apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a simple notification method (such as LED indicator) is used to notify users that charging has stopped, then the notification system is simple and easy to implement, but the user cannot be notified of detailed information such as the reason why the battery is not being charged
Solution Approach 1:
The notification system is segmented into two distinct power modes: first power for simple LED notifications and second power for detailed display notifications. This segmentation allows the system to provide comprehensive information (resolving the information loss) while maintaining simplicity for routine cases (managing complexity) by selectively activating the appropriate notification level based on authentication results.
Solution Approach 2:
The notification system dynamically adjusts its complexity based on the authentication outcome. When authentication fails, the system transitions from simple LED notification to a more complex display-based notification that provides detailed reasons. This dynamic adaptation resolves the contradiction by only introducing complexity when necessary to convey critical information.
2Loss of information
If the power receiving apparatus continuously transmits power for notification display, then detailed information can be provided to the user, but power is wasted through unnecessary transmission
Solution Approach 1:
The power transmission is structured as periodic and conditional rather than continuous. The system transmits first power during authentication, then conditionally transmits second power only when authentication fails and notification is required. This periodic transmission pattern ensures information is delivered when needed while avoiding continuous power waste.
Solution Approach 2:
The system uses feedback from the authentication result to control power transmission. When authentication succeeds, no further power transmission occurs. When authentication fails, the system receives feedback that triggers a conditional second power transmission for detailed notification. This feedback mechanism ensures power is only transmitted when necessary, resolving the energy loss issue.

AI summary
A power receiving apparatus comprises a power receiving unit that receives first power or second power from a power transmission apparatus; and a control unit that (a) requests the power transmission apparatus to transmit the first power, (b) determines whether or not a battery is a genuine battery by using the first power transmitted from the power transmission apparatus, (c) requests the power transmission apparatus to transmit the second power, when the battery is not a genuine battery, and (d) notifies a user of a reason why the battery is not being charged by using the second power transmitted from the power transmission apparatus.
