Camera Grip Temporary Cancel Mechanism for Lock Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses have poor operability when switching between lock and unlock states, requiring users to remove their hand from the grip to cancel the lock state, making it difficult to promptly switch and operate, especially in vertical positions.
Innovation Solution
An imaging apparatus with a setting unit that allows for a prohibit state on specific setting items, an operation member to change these settings, and a temporary cancel member, controlled by a unit that prevents changes when the prohibit state is set unless the cancel member is operated, enabling swift switching between lock and unlock states without erroneous operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lock function is implemented to prevent unintentional parameter changes, then reliability is improved, but ease of operation deteriorates because users must remove their hand from the grip to cancel the lock state
Solution Approach 1:
A temporary cancel member (release member) is introduced as an intermediary element that mediates between the locked state and the ability to change parameters. This release member, when operated, temporarily cancels the locked state without requiring the user to remove their hand from the grip, thus maintaining both reliability and ease of operation
2Reliability
If a lock function is implemented to prevent erroneous operations, then reliability is improved, but speed of switching between lock and unlock state deteriorates
Solution Approach 1:
The release member serves as a quick-access intermediary that enables rapid switching between locked and unlocked states. By providing a dedicated, easily operable component that temporarily cancels the lock state, the system achieves fast switching speed while maintaining the reliability of the lock function when activated
Solution Approach 2:
The system dynamically transitions between locked and unlocked states based on the operation of the release member. The locked state can be quickly toggled to an unlocked state when needed, and automatically returns to locked state after a predetermined period, providing dynamic adaptability that enhances both speed and reliability
3Reliability
If parameters are locked to prevent changes, then reliability is improved, but adaptability deteriorates because users cannot quickly adjust settings when needed
Solution Approach 1:
The parameter locking system is made dynamic through the release member mechanism. Parameters remain locked by default for stability, but can be temporarily unlocked by operating the release member, allowing users to adapt settings when needed. After a predetermined period, the system automatically returns to the locked state, balancing parameter stability with operational flexibility
Solution Approach 2:
The system performs preliminary locking of parameters to prevent unintentional changes. When users need to change parameters, they can operate the release member to temporarily cancel this preliminary lock state, allowing parameter changes. The system then automatically reinstates the lock state after a predetermined period, providing both protection and flexibility

AI summary
An imaging apparatus having a lens or a mount unit for mounting a lens on an object side surface of an apparatus main body and a grip unit at an end portion on one side of the apparatus main body, includes a setting unit to set a prohibit state that prohibits changing a setting value, an operation member for changing the setting value, a temporary cancel member, and a control unit to perform control. Where the prohibit state is set and if the temporary cancel member has not been operated and the operation member has been operated, the control unit controls not to change the setting value. Where the prohibit state is set and if the temporary cancel member has been operated and the operation member has been operated, the control unit changes the setting value according to an operation performed on the operation member.
