Menu Screen Control With Persistent Tab Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multifunction peripherals require repeated password authentication when switching between tabs, degrading operability.
Innovation Solution
A control apparatus with a locking unit that maintains a tab in an unlocked state after initial password authentication, allowing seamless transitions between menu screens without repeated password inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password authentication is required for each tab selection, then security is improved, but operability deteriorates
Solution Approach 1:
The system performs password authentication in advance when a user first accesses a protected tab. Once authenticated, the system maintains an unlocked state for that tab, allowing subsequent selections without repeated authentication. This preliminary action resolves the contradiction by establishing security upfront while enabling seamless subsequent operations.
Solution Approach 2:
The system tracks the authentication state of each tab and provides feedback by maintaining unlocked states for authenticated tabs. When a user selects a tab that has been previously authenticated, the system recognizes this through state management and allows access without re-authentication. This feedback mechanism resolves the contradiction by remembering authentication history and adjusting access control accordingly.
2Reliability
If repeated password authentication is required when switching between tabs, then security is maintained, but user experience deteriorates
Solution Approach 1:
The system performs password authentication in advance when a user first accesses a protected tab. Once authenticated, the system maintains an unlocked state for that tab, allowing subsequent selections without repeated authentication. This preliminary action resolves the contradiction by establishing security upfront while enabling seamless subsequent operations.
Solution Approach 2:
The system maintains continuous unlocked states for authenticated tabs, allowing users to switch between tabs without interruption for re-authentication. The useful action of accessing tabs continues smoothly without repeated authentication pauses, resolving the time loss issue while maintaining security through initial authentication.

AI summary
A control apparatus includes a first display controller that displays selection areas on a display unit, a locking unit that controls the control apparatus in a locked state, a changing unit that changes the state of the control apparatus from the locked state to a released state based on input of a password in the state of the control apparatus controlled in the locked state, a second display controller that displays a second menu screen corresponding to a second selection area on the display unit based on selection of the second selection area, and a third display controller that displays the second menu screen without the input of the password in a case where the second menu screen is displayed after the change from the locked state to the released state and the first selection area is selected after the display of the second menu screen.
