Lens Module Sectional Barrel Threaded Spacer Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing lens module assembly method is too simple and lacks stability, making it prone to misassembly and requiring a more robust and efficient structural design for electronic devices.
Innovation Solution
A sectional lens module structure that uses a thread or clamp fitting mechanism between the lens barrel and spacer to securely assemble and align lenses, allowing for easy correction of misassembly and enhancing the stability of the integral module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an integrated lens barrel structure with simple assembly is used, then the manufacturing process is simplified, but the assembly stability and reliability deteriorate
Solution Approach 1:
The lens barrel is divided into multiple sections (first lens barrel and second lens barrel) that can be assembled separately and then connected through threading. This segmentation allows for more stable assembly while maintaining manufacturing efficiency, as each section can be pre-assembled and tested independently before final integration.
Solution Approach 2:
A stopper component is introduced as an intermediary element between the first and second lens barrels. The stopper provides a reliable connection interface through threading mechanisms, ensuring assembly stability while simplifying the overall assembly process by providing a clear assembly guide and stopping position.
2Ease of operation
If lenses are installed from the bottom of the lens barrel, then the assembly process is simplified, but the risk of misassembly increases
Solution Approach 1:
The stopper is pre-installed in the second lens barrel with its threaded structure prepared in advance. This preliminary action provides a clear assembly guide for the first lens barrel, ensuring that components are assembled in the correct orientation and position, thereby preventing misassembly while maintaining operational convenience.
Solution Approach 2:
The threaded connection between the first and second lens barrels provides tactile and mechanical feedback during assembly. The threading mechanism naturally guides the components into proper alignment and provides a clear indication when correct assembly is achieved, reducing the risk of misassembly.
3Strength
If a fixed integrated structure is used, then the structural strength is improved, but the ability to correct misassembly is reduced
Solution Approach 1:
The lens barrel assembly uses reversible threading mechanisms that allow for dynamic adjustment and disassembly. The threaded connections can be easily tightened to provide strong structural strength during operation, but can also be conveniently loosened and re-tightened if misassembly occurs, providing both strength and ease of correction.

AI summary
A lens module, including: a lens barrel, a first lens group having at least one lens and accommodated in the lens barrel, a spacer provided at an end of the lens barrel close to an image side, and a second lens group having at least one lens and accommodated in the spacer, the lens barrel includes a first barrel wall forming a light aperture, a second barrel wall bending and extending from the first barrel wall, the lens barrel further includes a first inner wall and a first outer wall corresponding to the first inner wall, the spacer includes a second inner wall and a second outer wall corresponding to the second inner wall, the lens barrel is fitted and fixed with the spacer. The lens module provided by the present disclosure can be assembled section by section, which is more convenient and makes the module structure more stable.
