Vehicle Camera Bracket With Elastic Latching to Prevent Wobble
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle mount camera brackets fail to prevent wobbling in both up-down and left-right directions, require complex assembly adjustments, and consist of multiple parts.
Innovation Solution
A bracket design with a base portion fixed to the window glass, including abutment and support portions with elastic engagement pieces that allow for easy assembly and minimize wobbling by allowing upward movement of the camera's rear end as a fulcrum, reducing the need for precise alignment and minimizing the number of parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the bracket is made by a bracket main body and the plate spring formed separately, then the engagement structure is simple, but the number of parts is not minimized
Solution Approach 1:
The elastic engagement pieces are integrated directly into the second support portions of the bracket main body, eliminating the need for a separate plate spring component. This merging of the elastic engagement function into the existing bracket structure reduces the total number of parts while maintaining the simplicity of the engagement mechanism. The bracket now consists of a single main body with built-in elastic engagement capabilities.
2Reliability
If precise alignment of the claw portion with the hole portion is required during assembly, then the engagement structure is secure, but the assembly operation becomes complex
Solution Approach 1:
The elastic engagement pieces automatically engage with the engagement projection when the camera is mounted on the bracket. The elastic deformation and returning mechanism provides self-aligning and self-latching functionality, eliminating the need for precise manual alignment during assembly. The user simply needs to mount the camera, and the elastic engagement pieces will automatically secure it in the correct position.
Solution Approach 2:
The elastic engagement pieces utilize elastic deformation as a parameter change mechanism. During assembly, the elastic pieces deform to accommodate the engagement projection, then return to their original shape to secure the camera. This dynamic parameter change (elastic deformation) allows for easy assembly without precise alignment while maintaining secure engagement.

Function Achieved in This Case
The solution effectively prevents wobbling in both up-down and left-right directions, simplifies the assembly process by eliminating the need for precise adjustments, and reduces the number of bracket components.
Implementation Method 1
the elastic engagement piece permitting, by elastic deformation thereof, an upward movement operation of a rear end portion of the vehicle mount camera
Implementation Method 2
engaging a second supported portion provided on the vehicle mount camera by elastic returning at a finish position of the upward movement operation

AI summary
A bracket includes an abutment portion for a front end portion of a vehicle mount camera, first support portions located at a rear side than the abutment portion to receive first supported portions provided at the vehicle mount camera from a rear side, and second support portions located at right and left at a rear side than the first support portions, for receiving therebetween a rear end portion of the vehicle mount camera. The left and right second support portions respectively include elastic engagement pieces, the elastic engagement piece permitting, by elastic deformation, an upward movement operation of a rear end portion of the vehicle mount camera at a first supported portion as fulcrum from a state that the first support portion receives the first supported portion, and engaging a second supported portion provided in the vehicle mount camera by elastic returning at a finish position of the upward movement.
