Lens Assembly D-Cut Flange for Camera Module Miniaturization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to miniaturize camera modules while maintaining performance and image quality, as simple size reduction can lead to unintended light reflection and flare phenomena due to refracted light being reflected inside the lens barrel.
Innovation Solution
The lens assembly features D-cut portions and circular arc portions on the flange portion, which are designed to be symmetrical and spaced apart, allowing for miniaturization while maintaining optical performance and preventing flare phenomena by ensuring proper contact and alignment with the lens barrel, thus reducing the size of the camera module without compromising image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the size of the camera module is reduced, then miniaturization is achieved, but unintended light reflection and flare phenomena occur
Solution Approach 1:
The patent converts the harmful effect of light reflection into a beneficial one by designing the flange portion with D-cut portions and circular arc portions. These structural features intentionally create controlled light reflection paths that prevent flare phenomena, transforming the potentially harmful light reflection into a mechanism that eliminates the harmful effect.
Solution Approach 2:
The patent applies local quality by creating specific geometric features (D-cut portions and circular arc portions) at particular locations on the flange portion. These localized structural modifications alter the light reflection characteristics only in specific areas, preventing flare while maintaining the overall compact design.
2Reliability
If various configurations are added to improve camera module performance, then image quality is improved, but the size of the camera module increases
Solution Approach 1:
The flange portion is designed to serve multiple functions simultaneously: it provides structural support for mounting the lens, creates controlled light reflection to prevent flare, and maintains compact dimensions. The D-cut portions and circular arc portions enable the same structural element to fulfill both mechanical and optical functions, avoiding the need for additional separate components.
3Volume of moving object
If the size of each configuration is simply reduced to miniaturize the camera module, then size is reduced, but light reflection from inner surfaces increases
Solution Approach 1:
The patent employs asymmetry by designing the flange portion with D-cut portions and circular arc portions that create non-uniform light reflection surfaces. This asymmetric geometry prevents symmetric reflection paths that would cause flare, while allowing the lens barrel to maintain a compact size. The asymmetric features disrupt the regular reflection patterns that occur in conventional symmetric designs.

AI summary
A lens assembly includes a lens including an optical portion refracting light and a flange portion extended along a periphery of at least a portion of the optical portion, and a lens barrel accommodating the lens. The lens includes a first D-cut portion on one side surface of the flange portion spaced apart from the lens barrel and a second D-cut portion on another side surface of the flange portion spaced apart from the lens barrel, wherein the first D-cut portion and the second D-cut portion each include first inclined surfaces, and the first inclined surfaces are spaced apart from respective ends of the first D-cut portion and the second D-cut portion by a predetermined interval.
