Camera Accessory Locking Structure for Fast Secure Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses, such as digital cameras, face challenges in attaching and detaching accessories efficiently due to the need for screw turning or camera rotation, which is time-consuming and can impair portability.
Innovation Solution
The electronic apparatus incorporates a tightening member with a first screw engagement portion and a first lock portion, allowing for easy attachment and detachment of accessories through a rotation locking member with a second lock portion that engages with the first lock portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tripod screw is used to attach accessories to the camera, then the accessory can be securely fixed, but the attachment and detachment process becomes time-consuming due to screw turning or camera rotation
Solution Approach 1:
The tightening member is divided into distinct functional segments: a first screw engagement portion for secure attachment and a first lock portion for rapid locking. This segmentation allows each part to perform its specific function optimally - the screw portion provides reliable fixation while the lock portion enables quick attachment and detachment without time-consuming screw turning
Solution Approach 2:
The first lock portion acts as an intermediary mechanism between the user and the screw engagement portion. Instead of directly turning screws or rotating the camera, the user operates the lock portion which then actuates the tightening mechanism, significantly reducing the time required for attachment and detachment while maintaining secure fixation
2Ease of operation
If an attachment is attached to the bottom surface of the camera to simplify accessory attachment, then attachment and detachment becomes easier, but the camera's size increases and portability is impaired
Solution Approach 1:
The tightening member with lock portion is designed to be integrated within or closely coupled to the camera body structure. The lock portion and screw engagement portion are arranged in a nested or compact configuration that minimizes the increase in camera volume while still providing simplified attachment and detachment operation
Solution Approach 2:
The locking mechanism utilizes rotational movement around a central axis in a different dimensional plane rather than requiring bottom surface attachment. The first lock portion rotates around the central axis of the tightening member, enabling easy operation without adding significant volume to the camera body
3Productivity
If a rotation locking member is used for quick attachment, then attachment speed improves, but the structure becomes more complex
Solution Approach 1:
The first screw engagement portion and first lock portion are combined into a single integrated tightening member. This merging reduces the number of separate components and simplifies the overall structure while maintaining the high attachment speed provided by the rotational locking mechanism
Solution Approach 2:
The tightening member serves multiple functions simultaneously: the first screw engagement portion provides secure attachment, while the first lock portion enables rapid locking and detachment. This multi-functionality is achieved within a single component rather than requiring multiple separate mechanisms, thereby reducing structural complexity while improving productivity

AI summary
An electronic apparatus includes a tightening member having a first screw engagement portion and a first lock portion. The electronic apparatus is configured to allow for attachment and detachment of an accessory apparatus, which includes a rotation locking member having a second lock portion that rotates around a central axis of the tightening member and that engages with the first lock portion, and the tightening member is positioned coaxially with the first screw engagement portion and is provided outside the first screw engagement portion but inside the electronic apparatus.
