Lens Driving Adapter Universal Compatibility Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lens driving adapters are limited in their ability to attach to lens barrels with varying outer diameters, as they are designed for specific diameters, restricting their universal compatibility.
Innovation Solution
A lens driving adapter with a modular design featuring first and second contact portions that can engage with the outer circumferential surfaces of lens barrels of different diameters, coupled with a fixing member to securely attach to any lens barrel, ensuring stable operation without interference or backlash.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lens driving adapter is designed for a specific lens barrel outer diameter, then the gear mesh accuracy and operational stability are improved, but the adaptability to different lens barrels is reduced
Solution Approach 1:
The adapter body is segmented into multiple contact portions (first contact portion and second contact portion) that can independently engage with different circumferential portions of lens barrels with varying outer diameters. This segmentation allows the adapter to maintain stable gear meshing while adapting to different lens barrel sizes.
Solution Approach 2:
The adapter is designed with universal compatibility to attach to lens barrels of different outer diameters. The fixing member and multiple contact portions enable a single adapter design to serve multiple lens barrel types, achieving multi-functionality without compromising operational stability.
2Ease of manufacture
If a lens driving adapter is designed with a fixed structure for specific lens barrels, then the manufacturing precision and assembly ease are improved, but the adaptability to various lens barrel outer diameters is reduced
Solution Approach 1:
The adapter incorporates a movable contact portion that can dynamically adjust its position to accommodate different lens barrel outer diameters. This dynamic structure maintains ease of manufacture while enabling adaptability across various lens barrel sizes.
Solution Approach 2:
The adapter design allows for parameter changes in the contact portions to match different lens barrel outer diameters. By adjusting the engagement parameters of the contact portions, the adapter can be easily assembled onto lens barrels of varying sizes without complex manufacturing requirements.

AI summary
The lens driving adapter is detachably attachable to a lens barrel on which an operation member is provided. The adapter includes a driver configured to drive the operation member, and an adapter body holding the driver. The adapter body includes a first contact portion and a second contact portion that are protrusions contactable with two circumferential portions in an outer circumferential surface of the lens barrel. The first and the second contact portions are contactable with outer circumferential surfaces of lens barrels whose outer diameters are mutually different. The adapter body includes a fixing member configured to fix the adapter body to any of the lens barrels.
