Camera Actuator Architecture for Independent Focus and Anti-Shake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera technologies face challenges in simultaneously achieving optimal focusing and anti-shake functions, often compromising one effect for the other due to the deformation of liquid lenses used for both purposes.
Innovation Solution
An actuator system comprising a stator assembly, focusing mover assembly, and anti-shake mover assembly, which interact with a fluid lens and a first lens to independently adjust the curvature of the fluid lens for focusing and translate the first lens for anti-shake, respectively, allowing for separate control of focusing and anti-shake functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fluid lens is used for both focusing and anti-shake functions, then the camera structure can be simplified, but the focusing and anti-shake effects interfere with each other
Solution Approach 1:
The patent divides the camera system into two independent functional modules: a first lens assembly dedicated to focusing and a fluid lens assembly dedicated to anti-shake. This segmentation allows each module to perform its specific function without interference, resolving the contradiction between structural simplicity and functional reliability.
Solution Approach 2:
The patent introduces an actuator as an intermediary device that independently controls the first lens for focusing and the fluid lens for anti-shake. This intermediary mechanism enables separate control of the two functions, preventing mutual interference while maintaining a relatively simple overall structure.
2Reliability
If separate assemblies are used for focusing and anti-shake, then functional interference is reduced, but device complexity increases
Solution Approach 1:
The patent merges the focusing and anti-shake assemblies into a single integrated camera structure where the first lens and fluid lens are positioned in different optical paths. This combining approach reduces overall device complexity while maintaining functional independence, as both functions share the same camera body and optical system.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables independent achievement of high-resolution focusing and optical image stabilization, reducing interference between the two functions and improving overall image quality by allowing separate control of focusing and anti-shake processes.
Implementation Method 1
a focusing mover assembly configured to be connected with the fluid lens; and an anti-shake mover assembly configured to be connected with the first lens. The focusing mover assembly is configured to move along a first direction of the seat by interacting with the stator assembly, for adjusting a curvature of the fluid lens
Implementation Method 2
The anti-shake mover assembly is configured to translate in a plane perpendicular to the first direction by interacting with the stator assembly, for driving the first lens to move
