Camera Module Bracket with Positioning Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual camera modules require a separate process for optical axis alignment, which is inefficient.
Innovation Solution
A camera module design featuring a first bracket with a hole and a second bracket with a groove, where the second lens module is smaller than the groove and has protrusions to secure its position, allowing for integrated and aligned optical axis alignment without a separate process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dual camera modules are coupled to a bracket, then the ability to photograph different parts and synthesize images is improved, but the complexity of optical axis alignment process increases
Solution Approach 1:
The bracket is pre-designed with positioning structures (positioning holes, positioning protrusions, guide grooves) that automatically align the optical axes of multiple camera modules during assembly. This preliminary design eliminates the need for separate post-assembly alignment processes, resolving the contradiction between versatility and alignment complexity.
Solution Approach 2:
The camera modules utilize the bracket's built-in positioning features to self-align their optical axes without requiring external alignment tools or separate adjustment processes. The guide grooves and positioning protrusions enable the modules to automatically find their correct positions, making the system self-aligning and reducing process complexity.
2Manufacturing precision
If a separate optical axis alignment process is used, then alignment precision can be achieved, but manufacturing time and productivity are reduced
Solution Approach 1:
The optical axis alignment function is merged into the bracket structure itself through integrated positioning features. The positioning holes, protrusions, and guide grooves combine multiple functions (alignment, positioning, guidance) into a single structural element, eliminating separate alignment operations and improving manufacturing efficiency while maintaining precision.
Solution Approach 2:
The alignment features are pre-formed in the bracket during bracket manufacturing, so that when camera modules are assembled, the alignment is automatically achieved without requiring separate alignment operations. This preliminary incorporation of alignment functionality maintains precision while significantly improving productivity.
