Solution Overview

Problem

There is a challenge in miniaturizing lens assemblies for electronic devices while maintaining high-quality image and video capture capabilities, as the increasing number of lenses and their diameter make it difficult to secure space in small devices.

Innovation Solution

The lens assembly design includes a barrel with D-shape planes, lenses with effective regions and flanges, and spacers with corresponding cuts, allowing for a compact configuration that maintains optical performance by reducing the size of the flange regions without compromising the effective regions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the number of lenses and lens diameter are increased to improve photographing performance, then image quality and brightness are improved, but the space required for mounting the lens assembly increases

Engineering Contradiction:
Improvephotographing performanceVSAvoidmounting space
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The patent introduces D-shape planes (asymmetric flat regions) on the cylindrical outer surfaces of the lens, spacer, and barrel. This asymmetric design allows the components to be mounted in a compact arrangement where the flat surfaces align, reducing the overall mounting footprint while maintaining the circular effective regions for optimal light transmission and image quality.

Inventive Principle:
Principle #4Asymmetry

2Volume of moving object

If the flange region size is reduced to miniaturize the lens assembly, then the overall size is reduced, but the structural stability and mounting capability may be compromised

Engineering Contradiction:
Improvelens assembly sizeVSAvoidstructural stability
Core Design Contradiction:
Volume of moving objectVSStrength

Solution Approach 1:

The D-shape planes create an asymmetric structure where the flat surfaces provide stable mounting surfaces for alignment and attachment, while the remaining curved portions maintain the necessary structural integrity. This asymmetric design allows reduced material usage compared to a complete circular flange, achieving miniaturization without sacrificing structural stability.

Inventive Principle:
Principle #4Asymmetry

AI summary

A lens assembly according to the present disclosure includes at least one lens, a spacer, and a barrel. The at least one lens having an effective region configured to refract light, a flange region formed on at least a part surrounding the effective region, and a first cut formed on a sub region of the flange region. The spacer includes a second cut formed to correspond to the first cut and is configured to maintain a distance between multiple lenses mounted in the barrel. Moreover, the barrel is configured to receive the at least one lens and the spacer, in which the lens and the spacer are disposed inside the barrel such that the first cut and the second cut correspond to a third cut formed on an outer circumferential surface of the barrel. Various embodiments of the lens assembly and an electronic device including the same are described herein.
