Electronic Device Power Supply Authentication and History Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face safety and usability issues due to the inability to distinguish between authentic and unauthentic battery packs, leading to potential malfunctions and reduced user-friendliness, as existing solutions require frequent user authentication and do not differentiate between battery packs and AC adapters.
Innovation Solution
An electronic device with an authentication unit, selection unit, storage unit, and permission unit that performs authentication, prompts user selection, stores authentication results, and permits use based on user confirmation, ensuring safety and convenience by differentiating between battery packs and AC adapters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication is performed every time power is turned on, then safety is improved, but user-friendliness deteriorates due to frequent prompts
Solution Approach 1:
The system performs authentication in advance when the power supply apparatus is first connected, stores the authentication result, and reuses this result for subsequent power-on operations. This preliminary action eliminates the need for repeated authentication prompts, maintaining safety while improving user-friendliness.
Solution Approach 2:
The system automatically manages authentication by storing results and detecting power supply apparatus detachment. When the apparatus is reconnected, the system self-determines whether authentication is needed based on the stored history, reducing manual user intervention and improving ease of operation.
2Reliability
If authentication is performed for all power supply apparatus, then safety is improved, but usability deteriorates because AC adapters are mistakenly treated as battery packs
Solution Approach 1:
The system applies different authentication rules to different types of power supply apparatus. Battery packs undergo authentication, while AC adapters are automatically recognized and permitted without authentication. This localized differentiation maintains safety for battery packs while improving usability for AC adapters.
Solution Approach 2:
The system changes the authentication parameter based on the type of power supply apparatus detected. For battery packs, authentication is required; for AC adapters, the system automatically adjusts to permit use without authentication. This parameter change resolves the contradiction between safety and usability.
3Ease of operation
If authentication history is stored, then user convenience is improved, but security risk increases if history is not properly managed
Solution Approach 1:
The system continuously monitors the connection state of the power supply apparatus and provides feedback by detecting detachment. When detachment is detected, the system automatically clears the authentication history, ensuring security is maintained while allowing convenient reuse when the same apparatus is reconnected.
Solution Approach 2:
The authentication history storage is dynamic rather than static. The system automatically updates the history state based on real-time detection of power supply apparatus detachment, clearing history when needed and preserving it when appropriate. This dynamic management balances convenience and security.

AI summary
An electronic device includes an authentication unit that performs authentication to determine whether a power supply apparatus connected to the electronic device is a predetermined apparatus, a selection unit that makes a user select whether to use the power supply apparatus, when the authentication has failed, a storage unit that stores information indicating that the authentication has succeeded or the user has selected to use the power supply apparatus as history information. When the power supply apparatus is detached from the electronic device, the history information is deleted from the storage unit. The electronic device permits use of the power supply apparatus connected to the electronic device when the history information is stored in the storage unit while the electronic device is in a power ON state.
