Movable Photosensitive Chip Module for Anti-Shake Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing photographing apparatuses struggle with hand-shake induced camera tilt, leading to unstable images, especially when the lens is heavy and difficult to move for anti-shake purposes.
Innovation Solution
A photographing apparatus design where the photosensitive chip module is mounted on the lens module and is movable within a plane parallel to the lens body, driven by a separate driving module, allowing for anti-shake compensation without moving the lens module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lens is moved for anti-shake, then image stability is improved, but the difficulty of operation increases when the lens is heavy
Solution Approach 1:
Instead of moving the lens module to achieve anti-shake compensation, the patent inverts the approach by moving the photosensitive chip module in the opposite direction. The lens module remains fixed and stationary, while the photosensitive chip module is displaced by the driving module to compensate for hand-shake, thereby resolving the contradiction between image stability and ease of operation.
2Manufacturing precision
If the lens module is made heavy for better image quality, then manufacturing precision is improved, but the ease of operation deteriorates due to difficulty in moving for anti-shake
Solution Approach 1:
The patent allows the lens module to be heavy for optimal image quality by inverting the anti-shake mechanism. Instead of requiring the heavy lens module to move, the photosensitive chip module is made movable and is displaced by the driving module to achieve anti-shake compensation, thus maintaining both high manufacturing precision and ease of operation.
3Reliability
If the photosensitive chip module is made movable for anti-shake, then image stability is improved, but the device complexity increases
Solution Approach 1:
The patent segments the photographing apparatus into distinct functional modules: a fixed lens module and a movable photosensitive chip module. The driving module is separately connected to the photosensitive chip module to provide anti-shake functionality. This segmentation allows the anti-shake function to be added without complicating the lens module structure, thereby improving image stability while managing device complexity through modular design.
