Camera Module Compression Mounting to Prevent Vignetting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of fixing a camera in an electronic device without increasing manufacturing costs and time due to the use of camera brackets and adhesives, which can cause detachment during the manufacturing process, leading to potential vignetting and the need for additional calibration.
Innovation Solution
An electronic device design incorporating a camera support member, a camera window, and a compression member to securely fix the camera module, eliminating the need for brackets and reducing adhesive use, thereby preventing detachment and calibration requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a camera bracket and adhesive are used to fix the camera, then the camera is securely fixed, but manufacturing cost and time increase due to material cost and additional bonding and calibration processes
Solution Approach 1:
The camera support member is integrated with the housing structure, merging the support function into the existing housing rather than using a separate bracket. This integration eliminates the need for additional components and reduces manufacturing complexity while maintaining secure camera fixation
Solution Approach 2:
The invention removes the camera bracket component entirely from the design, extracting only the essential support function and implementing it directly through the housing structure with the camera support member, thereby eliminating material costs and assembly steps associated with separate brackets
2Reliability
If a camera bracket and adhesive are used to fix the camera, then the camera is securely fixed, but manufacturing time increases due to additional bonding process and calibration process
Solution Approach 1:
The invention eliminates the camera bracket and reduces adhesive usage, removing the bonding process from manufacturing steps. The camera support member provides mechanical retention without requiring adhesive bonding or subsequent calibration processes, significantly reducing manufacturing time
Solution Approach 2:
The camera support member is pre-formed as an integral part of the housing structure, with the camera receiving area and support features already prepared during housing manufacturing. This preliminary preparation eliminates the need for separate bracket installation and alignment operations
3Ease of manufacture
If lens protection film is removed during manufacturing, then the lens is exposed for operation, but the camera may move away from designated position due to external force or repulsive force
Solution Approach 1:
The camera support member is designed with cushioning or damping features that absorb external forces and repulsive forces from the flexible printed circuit board, preventing camera displacement before it can occur during manufacturing processes such as lens protection film removal
Solution Approach 2:
The camera support member provides preliminary counter-action to external forces through its structural design, creating opposing forces that balance out the repulsive forces from the flexible printed circuit board and prevent camera position deviation during manufacturing operations

AI summary
An electronic device is provided. The electronic device includes a housing including a support member and a rear plate, a camera support member disposed between the support member and the rear plate, a camera module disposed on the support member, a camera window covering at least a part of the camera module, and a compression member disposed between the camera window and the camera module. The camera module may include a first area facing the camera support member, a second area facing the compression member, and a third area facing the camera window and at least partially surrounded by the compression member.
