Electronic Apparatus Lock Controls with Operation-Member Display Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often forget which operation member to use for setting or releasing the lock state in image capturing devices, leading to confusion and unintentional malfunctions.
Innovation Solution
An electronic apparatus with assignable functions to operation members, including a lock function, and a display control unit that shows information on the assigned lock function on a display unit upon receiving a predetermined operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information on the operation member that is a target of the lock operation is displayed, then the user can see what operation member is locked, but the user may still forget which operation member to use for setting or releasing the lock state
Solution Approach 1:
The system provides feedback by displaying information about the operation member that is targeted by the lock operation. When a lock operation is performed, the display unit shows which operation member will be affected, allowing the user to confirm and understand the lock target before the lock state is applied. This feedback mechanism helps users remember and identify the correct operation member for lock setting and release.
Solution Approach 2:
The system performs a preliminary display action before the lock operation is finalized. By showing information about the operation member that will be locked before the lock state is actually set, the system gives the user advance notice and opportunity to confirm the correct operation member. This preliminary information display prevents mistakes by ensuring the user identifies the right operation member before the lock takes effect.
2Reliability
If a lock function is added to operation members, then unintentional operations can be prevented, but users may be confused as to how to set or release the lock
Solution Approach 1:
The display unit provides feedback information about the lock operation target, showing which operation member is affected by the lock function. This feedback helps users understand the relationship between the lock operation and the targeted operation member, reducing confusion about how to properly set and release the lock while maintaining the reliability benefit of preventing unintentional operations.
Solution Approach 2:
The display unit acts as an intermediary between the lock operation and the operation members. It mediates the user's understanding by providing visual information about which operation member will be locked, bridging the gap between the abstract lock function and the concrete operation members, thereby reducing user confusion while maintaining operational reliability.
3Adaptability or versatility
If multiple operation members have assignable functions including lock function, then the system is more versatile, but the complexity of managing lock operations increases
Solution Approach 1:
The lock function is designed as a universal function that can be assigned to any operation member in the electronic apparatus. Rather than having dedicated lock mechanisms for each operation member, the system allows the lock function to be flexibly assigned to different operation members based on user needs, enhancing versatility while the display unit helps manage the complexity by clearly indicating which operation member is currently targeted by the lock operation.

AI summary
An electronic apparatus includes: a plurality of operation members to which functions specified by a user are assignable; and at least one memory and at least one processor which function as: an assignment unit configured to assign a function selected by the user to each of the plurality of operation members, where the functions assignable by the assignment unit includes a lock function that sets/releases a lock state in which operation for operation members is disabled; and a display control unit configured to control such that information on an operation member to which the lock function is assigned is displayed on a display unit in a case where a predetermined operation is received from the user.
