Bayonet Mount and Cable Guide for Camera Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing configuration of imaging devices and camera grips, which rely on screw mechanisms and pin connections, complicates quick and easy attachment and detachment, thereby worsening manipulability.
Innovation Solution
The implementation of a bayonet mechanism in both the imaging device and camera grip allows for attachable and detachable mounting, along with a cable guide system to manage connection cables, enhancing ease of use and manipulability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw mechanism is used to attach the camera grip to the imaging device, then the connection is secure and reliable, but the attachment and detachment process becomes time-consuming and complex
Solution Approach 1:
The mounting mechanism is segmented into a bayonet interface with separate engagement and locking phases. The grip can be quickly attached by aligning and rotating the bayonet interface, while security is achieved through distinct engagement teeth and a separate locking mechanism, allowing rapid attachment without complex screw operations.
Solution Approach 2:
Instead of using a screw mechanism that requires rotational tightening, the patent inverts the approach by using a bayonet mechanism where the grip is attached by rotating it into place with engagement teeth that automatically lock, transforming the tightening action into a simple rotational insertion that is both fast and secure.
2Reliability
If a pin plug and pin jack are provided at the centers of the mount sections for electrical connection, then electrical communication is established, but the jack is occupied and cannot be used for other accessories
Solution Approach 1:
The electrical connection components (pin plug and pin jack) are extracted from the central mount section area. The jack is repositioned to the side of the mount section, allowing the central area to remain available for other accessories while maintaining electrical connection capability through the separated positioning of the plug and jack.
Solution Approach 2:
The patent introduces a cable guide section as an intermediary element that manages the connection cable between the grip and imaging device. This cable guide system allows the electrical connection to function independently from the central mount section, enabling other accessories to be mounted at the center without interfering with electrical connectivity.
3Reliability
If the connection cable is routed through the center mount section, then electrical connection is achieved, but the cable obstructs rotational movement of the grip
Solution Approach 1:
The connection cable routing is moved from the central axial dimension to a peripheral dimension around the mount section. The cable is routed along the outer periphery of the grip and imaging device bodies, changing its spatial path from passing through the center to running along the external surface, thereby eliminating obstruction to rotational movement while maintaining electrical connection.
Solution Approach 2:
A cable guide section is introduced as an intermediary structure that channels and constrains the connection cable along a predetermined path around the mount section. This cable guide prevents the cable from interfering with the rotational movement of the grip while ensuring stable electrical connection, acting as a mediator between the cable and the rotating components.

AI summary
A mount section 35 on which a camera grip 60 is mounted in an attachable and detachable manner is provided in an imaging device 30, and a mount section 65 that is mounted on the imaging device 30 in an attachable and detachable manner is provided in the camera grip. The attachment and detachment of the camera grip 60 can be easily performed and manipulability can be improved by providing the mount sections 35 and 65 provided in the imaging device and the camera grip with a bayonet mechanism. Further, a connection cable 75 that connects the imaging device 30 and the camera grip 60 is wound or rewound around the mount section 65 in accordance with the rotational movement of a grip main body section 61 with the mount section 65 as the axis, and the connection cable 75 does not become an obstacle to the switch manipulation of a manipulation section 62 provided in the camera grip 60. The manipulability of an imaging system can be improved.
