Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing optical image stabilization technology is used to compensate for camera movement, then image stabilization is achieved, but attitude difference, resonance, and distortion issues occur
Solution Approach 1:
The patent segments the stabilization function into two independent parts: a first optical element that moves with the lens group to maintain relative position, and a second optical element that independently compensates for attitude changes. This segmentation allows each element to perform its specific function without interfering with the other, eliminating attitude difference and distortion issues while maintaining image stabilization.
2Reliability
If a movable optical element is introduced to change light path for stabilization, then image stabilization is achieved, but device complexity and space increase
Solution Approach 1:
The patent makes the lens holder serve multiple functions: it holds the lens group, provides the mounting structure for both the first and second optical elements, and enables both stabilization and attitude compensation functions. This multi-functionality reduces the need for separate structural components, thereby reducing device complexity and space occupation.
3Reliability
If traditional stabilization mechanisms are used, then image stabilization is achieved, but cost and space are increased
Solution Approach 1:
The patent merges the first optical element and the second optical element into a single integrated structure where both elements are mounted on the same lens holder and work together to achieve stabilization. This merging reduces the total number of separate components, simplifies the overall structure, reduces manufacturing cost, and decreases the space required for the stabilization mechanism.

Function Achieved in This Case
The system effectively stabilizes images without causing distortion, color shift, or blur, while saving cost and space, and enabling auto focusing and mode switching.
Implementation Method 1
When a current is introduced into the coil based on the position and attitude information, the respective magnet is driven to move according to a direction of the current

AI summary
An optical imaging system includes a sensor configured to obtain position and attitude information of the optical imaging system; an optical lens component; an image stabilizing mechanism, configured to change a path of the light based on the position and attitude information. The image stabilizing mechanism includes a first optical element; a support frame supporting the first optical element; at least two magnets, disposed on two sides of the first optical element, respectively; at least two coils, facing to the at least two magnets, respectively. When a current flows through the coil, the respective magnet is driven to move according to a direction of the current, to cause the movable support frame carrying the first optical element to move with respect to one or more axes to change the path of the light.
