Imaging Lens Assembly Module With Trimmed Surfaces for Miniaturization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging lens assembly modules for portable electronic devices face challenges in miniaturization while maintaining high imaging quality due to the integral formation of the barrel and base portion, which occupies significant space and complicates assembly.
Innovation Solution
The imaging lens assembly module features a baseplate and imaging lens assembly with symmetrically trimmed lens and barrel surfaces, allowing for a non-circular contour along the optical axis, and an integrally formed barrel and base portion, reducing size perpendicular to the axis and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the barrel portion and base portion are formed separately and assembled, then the assembly flexibility is improved, but the device complexity and assembly time increase
Solution Approach 1:
The patent merges the barrel portion and base portion into a single integrally formed component. This eliminates the need for separate assembly of these parts, reducing assembly steps and complexity while maintaining the structural functions of both portions. The integrated design directly resolves the contradiction by combining what was previously separate components into one unified part.
2Ease of manufacture
If the lens assembly uses a traditional circular contour, then the manufacturing process is simpler, but the miniaturization capability is reduced
Solution Approach 1:
The patent applies asymmetry by changing the lens assembly contour from a traditional circular shape to a non-circular shape with trimmed surfaces. This asymmetric design allows the assembly to fit more efficiently into the portable device housing, reducing the overall volume occupied by the lens assembly while enabling better space utilization in the device structure.
3Volume of moving object
If the lens assembly is miniaturized, then the device size is reduced, but the imaging quality may deteriorate
Solution Approach 1:
The patent applies local quality by implementing trimmed surfaces at specific locations on the lens and barrel portions rather than uniformly reducing all dimensions. The trimming is strategically applied to areas that do not compromise the optical path or imaging performance, allowing miniaturization in non-critical areas while maintaining the necessary quality in optical regions.
4Productivity
If the barrel portion and base portion are formed integrally, then the assembly time is reduced, but the adaptability for different configurations is limited
Solution Approach 1:
The patent designs the integrally formed barrel-base component with universal features that can accommodate different lens assembly configurations. The integrated structure includes standardized interfaces and mounting features that allow the same component design to work with various lens arrangements, maintaining configuration adaptability despite the unified construction.
