Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera devices with optical image stabilization cannot compensate for handshake in a direction parallel to the optical axis of the lens (Z-axis), limiting image stabilization effectiveness.
Innovation Solution
A camera device with a five-axis image stabilizer, comprising a base, carrying members, optical compensating components, and a guiding component, which allows the camera module to move and rotate along multiple axes, including an axis parallel to the optical axis, for enhanced image stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional four-axis image stabilization is used, then the structure is simpler and easier to manufacture, but handshake in the direction parallel to the optical axis (Z-axis) cannot be compensated
Solution Approach 1:
The patent adds a fifth compensation axis by enabling rotation around the optical axis (Z-axis), transforming the conventional four-axis stabilization system into a five-axis system. This dimensional expansion allows compensation for handshake movements in the previously unaddressed Z-axis direction, improving overall stabilization effectiveness while maintaining a manageable structural complexity through modular design
2Reliability
If the camera module is made movable and rotatable along multiple axes, then image stabilization is enhanced, but the device structure becomes more complex
Solution Approach 1:
The patent divides the image stabilization system into modular components: a movable platform for X-Y translation, a rotating mechanism for pitch-yaw rotation, and an additional rotation mechanism for Z-axis compensation. Each module can be manufactured and tested independently, then assembled together, reducing overall manufacturing complexity despite the enhanced five-axis functionality
Solution Approach 2:
The patent implements a nested structure where the camera module is mounted on a moving platform, which itself is mounted on a rotating mechanism, which is in turn mounted on the base structure. This nested arrangement allows compact integration of multiple degrees of freedom while maintaining ease of manufacture through standardized mounting interfaces and modular assemblies

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The camera device achieves better image stabilization by compensating for additional axes, resulting in improved image quality with five-axis image stabilization, beyond the limitations of conventional four-axis compensation.
Implementation Method 1
The first force interaction member and the second force interaction member are configured to be force-interacted, allowing the second carrying member to move relative to the first carrying member to optically compensate for the optical lens
Implementation Method 2
The third force interaction member and the fourth force interaction member are configured to be force-interacted, allowing the first carrying member to be guided by the guiding component to move on the base around an axis parallel to an optical axis of the optical lens to optically compensate for the optical lens
