Detachable Camera Accessory Layout for Rear-Side Key Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera accessories for image pickup systems have poor operability when used on a tripod, requiring users to move to the side of the apparatus for key operations due to the operation surface being on the same plane as the image pickup apparatus, especially in studio settings.
Innovation Solution
A camera accessory that can be attached and detached from the image pickup apparatus main body, featuring a configuration where the operation surface is parallel and opposite to the image pickup plane, with connecting terminals for signal and power transfer, and an operation portion that overlaps the main body's operation portion on the optical axis, allowing intuitive key operations from behind.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operation surface is disposed on the same surface as the side surface of the image pickup apparatus, then the accessory can be compact, but the user must move to the side for key operations reducing operability
Solution Approach 1:
The operation surface is repositioned from a side-surface arrangement to the rear surface of the accessory, creating a spatial separation between the operation surface and the image pickup plane. This dimensional repositioning allows users to access the operation surface from the rear without moving to the side, thereby improving operability while maintaining a compact form factor.
2Adaptability or versatility
If all functions are equipped in the image pickup apparatus main body in advance, then the apparatus can provide complete functionality, but the product becomes large and operability is reduced
Solution Approach 1:
The image pickup system is divided into a main body and a detachable accessory. The accessory contains specific functions (such as operation surfaces and connecting terminals) that can be attached only when needed. This segmentation allows the main body to remain compact while providing full functionality through optional accessory attachment.
Solution Approach 2:
The accessory is designed with multiple functions integrated into a single unit, including operation surfaces, connecting terminals for video signals and power, and expansion module attachment capabilities. This multi-functionality allows users to expand the main body's capabilities without adding separate dedicated devices.
3Ease of operation
If the operation portion overlaps the main body operation portion on the optical axis, then key operations can be performed from behind, but the accessory structure becomes more complex
Solution Approach 1:
The operation portion is positioned on the rear surface of the accessory, overlapping the main body's operation portion when viewed from the optical axis direction. This spatial arrangement allows users to perform key operations from behind the apparatus without moving to the side, improving accessibility while using the rear surface space efficiently.

AI summary
A camera accessory capable of improving operability is provided. The camera accessory capable of being attached to or detached from an image pickup apparatus main body including an image pickup plane and a camera accessory attachment portion, includes a first connecting terminal configured to perform at least one input or output of video signals, operating power, and control signals with respect to the image pickup apparatus main body, and a second connecting terminal configured to perform at least one input or output of the video signals, the operating power, and the control signals with respect to the outside of the camera accessory. In a state, in which the camera accessory is attached to the camera accessory attachment portion, an expansion module attachment portion and an operation portion are arranged to be substantially parallel to the image pickup plane and are arranged on a surface opposite to the image pickup plane.
