Dual-Material Lens Support Member for Rigidity and Flare Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lens bonding methods, such as direct bonding and pressing rings, face issues with lens lifting, deterioration, and insufficient rigidity, leading to defects in resolution and appearance, and may not adequately prevent flare.
Innovation Solution
A lens module design incorporating a support member with a first support member made of a material like plastic and a second support member made of a higher rigidity material, such as metal, where the second support member is spatially separate from the lens and lens barrel, and a pressing ring configuration with inclined portions to minimize flare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pressing ring is used to support the lens, then reliability is improved and flare is prevented, but rigidity is insufficient
Solution Approach 1:
The support member is constructed as a composite structure combining a first support member (first material) and a second support member (second material different from the first material). The second support member has greater rigidity than the first support member, creating a composite structure that achieves both reliability and sufficient rigidity.
2Force
If the second support member is disposed spaced apart from the lens, then coupling force with lens barrel is maintained, but support effectiveness may be reduced
Solution Approach 1:
The support member is divided into two distinct support members: a first support member that contacts the lens and provides support, and a second support member with higher rigidity that is disposed spaced apart from the lens. This segmentation allows each component to fulfill its specific function optimally.
Solution Approach 2:
The first support member acts as an intermediary between the lens and the second support member. It transmits the support force from the second support member (which has higher rigidity) to the lens, while maintaining proper spacing between the high-rigidity second support member and the lens itself.

AI summary
A lens module is provided. The lens module may include a lens barrel configured to accommodate a lens; and a support member disposed in the lens barrel, and configured to support the lens, wherein the support member includes a first support member formed of a first material, and a second support member formed of a second material different from the first material, wherein the first support member configured to contact and support the lens, and the second support member is disposed to be spaced apart from the lens, wherein a rigidity of the second support member is greater than a rigidity of the first support member.
