Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional image stabilization device structure is used, then vibration compensation function is achieved, but device volume becomes large
Solution Approach 1:
The patent combines multiple linkage mechanisms into an integrated assembly where the first and second linkage assemblies work together with shared components. The flexible elements serve dual purposes by connecting different linkages while enabling optical element movement, thereby reducing overall device volume while maintaining vibration compensation functionality.
Solution Approach 2:
The flexible elements perform multiple functions: they connect the optical element to the linkage mechanisms, enable movement along multiple directions, and provide structural support. This multi-functionality eliminates the need for separate guiding rods and linear bearings, significantly reducing device volume.
2Reliability
If conventional image stabilization device structure is used, then vibration compensation function is achieved, but structure becomes complicated
Solution Approach 1:
The patent extracts and eliminates unnecessary components such as linear bearings and guiding rods from the conventional structure. By using flexible elements that inherently provide both connection and movement guidance, the design simplifies the structure while maintaining the essential vibration compensation function.
Solution Approach 2:
The patent merges the functions of multiple separate components into integrated linkage assemblies. The first and second linkage assemblies are combined with shared flexible elements, reducing the number of parts and simplifying the overall structure while preserving the ability to compensate for vibrations in multiple directions.
3Volume of moving object
If compact image stabilization device is designed, then device volume is reduced, but manufacturing difficulty increases
Solution Approach 1:
The patent uses flexible elements (flexible beams) as key structural components that are relatively simple to manufacture. These flexible elements can be fabricated using standard PCB or metal bending techniques, making the compact design easier to produce despite the reduced device volume and integrated structure.
