Triangular Wave Contact and Hinge Mechanism for Accessory Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image pickup apparatuses face issues with accessory stability due to insufficient frictional force, complex operations for fixing and releasing rotational positions, and cumbersome cable management, particularly when using accessories like handles and display panels.
Innovation Solution
The image pickup apparatus employs a protrusion-recess fitting mechanism using triangular wave-shaped contact portions and a three-axis rotational hinge unit, allowing for stable accessory attachment, simple positional adjustments, and reduced cable area occupation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If flat-surface contact is used between accessory and apparatus body, then simple structure is achieved, but sufficient frictional force cannot be obtained causing accessory loosening
Solution Approach 1:
The contact portions are formed with triangular wave shapes (curved surfaces) instead of flat surfaces. This curvature increases the contact area and frictional force between the accessory and apparatus body, preventing accessory loosening while maintaining structural simplicity.
2Adaptability or versatility
If hinge unit with high degree of freedom is used for various display panel positions, then positioning versatility is improved, but operational complexity increases
Solution Approach 1:
The hinge unit is divided into multiple independent rotation mechanisms, each providing rotation around a specific axis. This segmentation allows the display panel to achieve various positions through simple sequential rotations rather than complex simultaneous movements, improving both versatility and ease of operation.
3Reliability
If cable is drawn out from side of display panel for signal communication, then connection is achieved, but large space is required and cable management becomes cumbersome
Solution Approach 1:
The cable exit position is moved from the side surface to the rear surface of the display panel, utilizing a different spatial dimension. This allows the cable to be routed behind the display panel rather than alongside it, significantly reducing the occupation area and simplifying cable management while maintaining signal communication.

AI summary
An image pickup apparatus that suppresses looseness of an accessory fastened to a fastening portion of an apparatus body. An image pickup apparatus includes an accessory that includes a pair of fastening members, and an apparatus body including two fastening portions to which the accessory is removably fastened using the pair of fastening members. The accessory is provided with a second fitting portion which is fitted to one of first fitting portions formed around the fastening portions, by protrusion-recess fitting, in a state in which the accessory is fastened to the fastening portions of the apparatus body using the fastening members. One of the first fitting portion and the second fitting portion is formed by two fitting portions provided in association with the fastening members, and the other is formed by at least one fitting portion.
