Camera Grip Attachment With Protected Electrical Contacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses with removable accessories, such as camera grips, face challenges in securely attaching and electrically connecting these accessories due to issues like cable management, loose fixation, and exposure of electrical contacts, leading to unstable connections and potential damage.
Innovation Solution
The design incorporates a screw-based attachment mechanism with concentric contact patterns and engagement parts that securely fix the accessory to the electronic apparatus, ensuring a stable electrical connection while protecting the contacts from external interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bayonet fixing is used to attach the grip to the image capture apparatus body, then the attachment is simple and quick, but the fixation is not firm and electrical connection becomes unstable
Solution Approach 1:
The patent combines bayonet fixing and rosette fixing mechanisms into a single attachment system. The grip can be quickly attached via bayonet fixing, and then securely locked via rosette fixing with screws, achieving both ease of operation and reliable fixation in one integrated system
Solution Approach 2:
The bayonet fixing mechanism performs preliminary attachment quickly, positioning the grip on the apparatus body before the rosette fixing mechanism is engaged to provide final secure locking, dividing the attachment process into preliminary and final stages
2Reliability
If electrical contacts are provided inside the rosettes for power supply and communication, then electrical connection is achieved, but the electrical contacts are damaged by the rosettes
Solution Approach 1:
The patent extracts the electrical contacts from the rosette structure itself and places them on separate dedicated contact portions. This separation removes the harmful interaction between rosette teeth and electrical contacts while maintaining electrical connection functionality
Solution Approach 2:
The attachment interface is segmented into distinct functional zones: the rosette structure for mechanical locking, separate contact portions for electrical connection, and engagement portions for positioning. This segmentation allows each component to perform its function without interfering with others
3Ease of operation
If the electrical contacts are exposed to the outside when the grip is not attached, then access is easy, but films are formed on the contacts due to unintended touch which may cause contact failure
Solution Approach 1:
The cover structure proactively prevents unintended contact with the electrical contacts by enclosing them when the grip is not attached. This preliminary protective action eliminates the need for user caution and prevents film formation before it can occur
Solution Approach 2:
The cover acts as an intermediary barrier between the external environment (including user fingers) and the electrical contacts. It mediates the interaction by providing physical separation, allowing the contacts to remain protected while maintaining system functionality

AI summary
An electronic apparatus to which an accessory is removably attached. One of a grip and an image capture apparatus body includes a first attachment part formed by a first screw, a first electrical connection part disposed outside the first screw, and a first engagement part formed outside the first electrical connection part. The other of them includes a second attachment part formed by a second screw and screwed with the first screw, a second electrical connection part disposed outside the second screw, and electrically connected to the first electrical connection part, and a second engagement part formed outside the second electrical connection part, and engaged with the first engagement part. When the first and second screws are screwed, the first and second engagement parts are engaged, and the first and second electrical connection parts are electrically connected.
