Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image shooting modules with multiple movable lens groups suffer from complex drive structures, affecting lens movement speed and precision, and reducing the shooting effect.
Innovation Solution
The image shooting module integrates a drive apparatus with a bearer and a lens guide rod, eliminating the need for a guide rail, and utilizes magnetic attraction and clamping mechanisms for simplified lens movement, enhanced by a position detection apparatus for closed-loop control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex drive structure is used to support multiple movable lens groups, then the zoom mode with higher shooting quality can be achieved, but the movement speed and precision of the lens are affected and the shooting effect is reduced
Solution Approach 1:
The patent divides the lens system into multiple independent movable lens groups (first lens group, second lens group, third lens group) that can be controlled separately. Each lens group is mounted on its own bearer and can be driven independently, allowing the system to achieve complex zoom functions while maintaining fast and precise movement for each individual lens group.
2Adaptability or versatility
If a complex drive structure is used to support multiple movable lens groups, then the zoom mode with higher shooting quality can be achieved, but the movement precision of the lens is affected
Solution Approach 1:
The patent segments the lens system into multiple independently controllable lens groups, each with its own bearer and drive mechanism. This segmentation allows precise control of each lens group's position and movement, improving overall movement precision while supporting complex zoom modes.
3Stability of the object's composition
If a guide rail is used for the bearer to move, then the bearer can be guided, but the movement system of the lens becomes complex and friction increases
Solution Approach 1:
The patent removes the guide rail component from the system entirely. Instead of using a guide rail to constrain bearer movement, the invention uses a direct drive mechanism where the drive apparatus acts on the bearer without intermediate guiding structures, thereby simplifying the movement system and reducing friction while maintaining stable bearer movement.
4Stability of the object's composition
If a guide rail is used for the bearer to move, then the bearer can be guided, but the friction in sliding of the lens increases
Solution Approach 1:
The patent eliminates the guide rail that causes friction during lens sliding. By using a direct drive mechanism where the drive apparatus directly acts on the bearer without intermediate guiding surfaces, the system reduces friction and improves movement efficiency while maintaining stable bearer movement through alternative constraint mechanisms.

Function Achieved in This Case
This configuration improves lens movement speed and precision, simplifies the movement system, and enhances the shooting effect while reducing friction and costs.
Implementation Method 1
a first magnet is disposed on the bearer, a second magnet is disposed on the lens, and the first magnet and the second magnet attract each other

AI summary
An image shooting module and/or an electronic device includes a motor structure and an image shooting assembly. A drive apparatus and a bearer of the motor structure are connected, a lens of the image shooting assembly is disposed on the bearer, and the lens is slidably connected to a lens guide rod. When the drive apparatus drives the bearer to move, the lens can be driven to move along the lens guide rod, to implement focusing, zooming, and the like of the lens.
