Camera Lens Protruding Group for Screen-to-Body Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera lens technologies face challenges in maximizing the front display region of electronic devices while maintaining effective camera functionality, leading to suboptimal screen-to-body ratios and increased device size.
Innovation Solution
A method of processing camera lenses involves configuring a first lens group for light incidence and a second lens group for light emission, where the second lens group is mounted into a lens barrel and the first lens group protrudes from the barrel, reducing the lens barrel's volume and allowing for miniaturization, and incorporating a light shielding layer to prevent flares.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the lens barrel volume is reduced to maximize front display region, then screen-to-body ratio is improved, but camera lens functionality may be compromised
Solution Approach 1:
The lens system is divided into two separate lens groups: a first lens group for light incidence and a second lens group for light emission. This segmentation allows each group to be optimized independently for their specific functions while fitting within a compact lens barrel, resolving the contradiction between reduced size and maintained functionality.
Solution Approach 2:
The patent utilizes the optical path dimension by allowing the first lens group to protrude from the lens barrel end surface while the second lens group remains inside. This dimensional arrangement enables effective camera functionality with a reduced lens barrel volume, improving screen-to-body ratio without compromising performance.
2Volume of stationary object
If the first lens group protrudes from the lens barrel to reduce barrel volume, then lens barrel size is minimized, but manufacturing complexity increases
Solution Approach 1:
The lens assembly is segmented into modular components (first lens group, second lens group, lens barrel) that can be manufactured separately and assembled systematically. The first lens group is positioned in a first accommodating space while the second lens group is positioned in a second accommodating space, with the first group protruding from the barrel end. This modular segmentation simplifies the manufacturing process despite the protruding configuration.
3Reliability
If a light shielding layer is added to prevent flares, then optical performance is improved, but device complexity increases
Solution Approach 1:
The light shielding layer is merged with the lens barrel structure, forming an integrated component rather than a separate additive element. The shielding layer is configured within the lens barrel to block stray light and prevent flares, improving optical performance without significantly increasing overall device complexity.
