Camera Module Image Stabilization Assembly with Perpendicular Sensor Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera modules struggle to effectively stabilize images during disturbances such as hand shake or vibration, leading to degraded image quality.
Innovation Solution
An image stabilization assembly is introduced, comprising a guide structure, a coil, and a magnet, which moves the image sensor to align the optical axis with a specified position on the image sensor, compensating for disturbances by moving the image sensor in perpendicular directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image stabilization assembly moves the image sensor to compensate for disturbances, then image quality is improved, but device complexity increases
Solution Approach 1:
The image stabilization assembly is divided into distinct functional components: a moving member that carries the image sensor, a guide structure that constrains movement to specific axes, and drive units (coils and magnets) that enable controlled displacement. This segmentation allows each component to be optimized independently while working together to stabilize the image sensor during disturbances, thereby improving image quality without unnecessarily increasing overall assembly complexity.
2Adaptability or versatility
If the image stabilization assembly is added to the camera module, then image stabilization function is achieved, but device complexity increases
Solution Approach 1:
The image stabilization assembly is designed with a modular structure where the moving member, guide structure, and drive units can serve multiple functions. The same assembly that stabilizes the image sensor can also be configured to support focus adjustment and other optical functions, allowing a single added component to provide multiple benefits to the camera module rather than requiring separate mechanisms for each function.
