Front Camera Assembly With Visual Alignment and Minimal Lens Gap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing front camera assembling structures in electronic devices suffer from large gaps between the lens and the camera hole, leading to a wider lens black edge that negatively impacts user vision and reduces the screen-to-body ratio, while requiring high precision in processing and assembly due to the involvement of multiple parts and complex tolerances.
Innovation Solution
A front camera assembling method that uses a visual positioning system to accurately position the lens and camera hole, reducing the number of parts and assembly steps, and employs an accommodation groove to minimize the gap size, allowing for a smaller camera hole aperture and lower precision requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a limiting groove structure is used to position the lens and camera body, then the lens position can be controlled, but the number of parts increases and assembly complexity increases
Solution Approach 1:
The patent combines the limiting groove structure with the camera hole structure into an integrated design. The limiting groove is formed directly on the middle frame at the camera hole location, eliminating the need for separate positioning components. This merging reduces the number of parts while maintaining the lens positioning function through the integrated groove structure that guides lens insertion and centers it relative to the camera hole.
2Manufacturing precision
If multiple parts are associated and assembled between the lens and camera hole, then positioning can be achieved, but the size chain becomes long and cumulative tolerance increases
Solution Approach 1:
The patent extracts and eliminates intermediate positioning parts from the assembly chain between the lens and camera hole. By using the limiting groove structure integrated into the middle frame, the design removes unnecessary intermediate components that would otherwise be required for positioning. This extraction shortens the assembly chain and reduces cumulative tolerance accumulation, as there are fewer interfaces and tolerance zones to manage.
3Adaptability or versatility
If the camera hole aperture is designed to be relatively large, then lens eccentricity can be accommodated, but the gap between camera hole and lens increases
Solution Approach 1:
The patent introduces a dynamic adjustment mechanism through the limiting groove structure that allows the lens to be positioned and adjusted within the camera hole. The groove provides guidance and constraint while allowing for minor adjustments to accommodate lens eccentricity. This dynamic positioning capability enables the use of a smaller camera hole aperture without sacrificing the ability to handle lens positioning variations, as the groove structure adapts to ensure proper lens placement.
