Wearable Camera Magnetic Attachment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable cameras often fall off during use due to inertia, especially when users are in motion, and existing solutions like clips hinder charging operations.
Innovation Solution
A wearable camera design featuring a casing with a magnetically attached casing holding member that restricts downward movement and allows easy detachment for charging, or a clip-type attachment that securely fastens to clothing without screws, ensuring the camera remains attached during use and facilitates charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a clip is screwed to the rear surface of the casing to enhance holding ability, then the holding ability is improved, but the charging operation becomes difficult because the clip obstructs the charging contact
Solution Approach 1:
The holding member is divided into two functional parts: a clip portion for holding the casing and a protrusion portion for charging interaction. This segmentation allows the clip to provide holding ability while the protrusion enables charging without obstruction, resolving the contradiction between reliable attachment and ease of charging operation
Solution Approach 2:
The protrusion acts as an intermediary element that mediates between the holding function and charging function. It protrudes from the attachment surface to engage with the charger, serving as a charging interface that is not obstructed by the clip, thus enabling charging operation while maintaining holding ability
2Measurement precision
If the wearable camera is mounted on clothes to capture field of view, then the imaging function is improved, but the camera may fall off due to inertia when the user moves
Solution Approach 1:
The holding member combines a clip structure with a protrusion structure to create a composite attachment mechanism. The clip provides initial attachment to the clothes while the protrusion engages with the charger during charging, creating a multi-functional composite structure that maintains mounting stability during use and enables easy charging

AI summary
A wearable camera includes a casing that hoses an imaging unit and includes a front surface in which a lens is exposed, and a rear surface in a direction along a vertical surface serving as a surface on a mounting side, an attachment surface that is formed on the rear surface and on which a casing holding member is detachably attached without screwing, and a protrusion that comes in contact with a magnet protruding from the casing near an upper end of the attachment surface and attached to the attachment surface to restrict downward movement of the casing with respect to the magnet.
