Multi-Barrel Lens Structure for Extended Optical Zooming Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lens structures are limited in optical zooming path extension due to the restrictive movement path of guiding pins, which prevents further prolongation of the zooming path.
Innovation Solution
A lens structure comprising multiple barrels with interlocking groove and pin mechanisms allows for independent movement of the barrels, enabling a continuous optical zooming path by sliding pins along grooves, thereby extending the zooming path without restricting barrel movement.

Engineering Contradiction Analysis
1Length of moving object
If the guiding pin remains connected to the guiding groove to regulate the movement path, then the movement path is controlled, but the optical zooming path cannot be prolonged further
Solution Approach 1:
The lens structure is divided into multiple independent barrels (first barrel, second barrel, third barrel) that can move relatively to each other. Each barrel has its own guiding mechanism with grooves and pins, allowing segmented movement control. This segmentation enables the optical zooming path to be extended through multiple stages of relative movement without requiring a single complex guiding mechanism.
Solution Approach 2:
The barrels are arranged in a nested configuration where the first barrel is disposed outside the third barrel, and the second barrel is disposed inside the third barrel. This nested structure allows multiple barrels to move relatively while maintaining a compact overall form, enabling extended optical zooming path without proportionally increasing the device's external dimensions.
2Ease of operation
If a straight forwarding barrel with a groove is used to define the optical zooming path, then the zooming function is achieved, but the guiding pin is restricted by the movement path
Solution Approach 1:
The guiding mechanism transitions from a static single-path design to a dynamic multi-stage design where different barrels can move relatively along different paths. The grooves and pins are configured to allow flexible movement during zooming operations, with the ability to switch between different movement modes (e.g., optical zooming, focus adjustment) without being restricted to a fixed path.
Solution Approach 2:
The lens structure utilizes multi-dimensional relative movement between nested barrels. Instead of a single linear path, the system allows movement in multiple directions and planes through the coordinated action of multiple barrels with different groove configurations, effectively extending the optical zooming path by adding dimensional complexity to the movement mechanism.

AI summary
The lens structure comprises a first barrel, a second barrel and a third barrel. The second barrel has a first guiding groove and comprises a first pin. The third barrel has a second guiding groove and a second pin. The first barrel is rotatably disposed outside of the third barrel, and the second barrel is translatably but not rotatably disposed inside of the third barrel. The first pin of the second barrel slides along the second guiding groove of the third barrel, and the second pin of the third barrel slides along the first guiding groove of the second barrel.
