Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If spheroids are used in guiding grooves to enable low-friction movement, then movement smoothness is improved, but reliability deteriorates due to slippage, sticking, or spinning of spheroids
Solution Approach 1:
The guiding groove is divided into multiple segments with each segment containing a corresponding guiding protrusion. This segmentation ensures that the prism supporting part maintains continuous contact with the guiding groove through multiple engagement points, preventing slippage and spinning while preserving smooth movement capability.
Solution Approach 2:
The guiding protrusion acts as an intermediary element between the guiding groove and the prism supporting part. It transmits motion control while maintaining stable contact, effectively mediating between the need for smooth movement and the need for reliable positioning without spheroid-based mechanisms.
2Device complexity
If conventional spheroid-based guiding mechanisms are used, then device complexity is reduced, but manufacturing precision deteriorates due to inability to reach predetermined positions
Solution Approach 1:
The guiding groove is segmented into multiple portions with corresponding guiding protrusions, creating a more precise control mechanism that can accurately reach predetermined positions while maintaining reasonable structural complexity through the repetitive modular design.
Solution Approach 2:
The patent replaces the spheroid-based mechanical guidance system with a groove-protrusion guidance system. This substitution eliminates the reliability issues of spheroids while achieving superior positioning precision through the distributed contact points provided by the segmented groove structure.
3Adaptability or versatility
If prism supporting parts are electromagnetically driven to rotate, then image compensation capability is improved, but device complexity increases due to additional driving components
Solution Approach 1:
The guiding groove structure serves multiple functions: it guides the movement of the prism supporting part, provides positioning control through segmented engagement points, and works with the electromagnetic driving mechanism to achieve precise image compensation. This multi-functionality reduces the need for separate complex driving components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures accurate image compensation by preventing slippage and blockage, allowing prism carrying members to move precisely to predetermined positions for effective optical image stabilization.
Implementation Method 1
The guiding grooves of the prism supporting parts and the guiding groove of the base part are combined with the spheroids in a rolling manner so that the prism supporting parts could move relative to the base part with low friction
Implementation Method 2
optical image stabilization of the image compensation device is achieved by image compensation by physically adjusting an optical axis
