Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If autofocus, zoom, and optical image stabilization functions are implemented by moving lens modules and reflection modules, then the camera module achieves advanced imaging capabilities, but interference occurs between components affecting structural reliability
Solution Approach 1:
The first auxiliary member acts as an intermediary component between the reflection module and the housing. It includes buffer members that physically intervene to absorb impacts and prevent direct contact between the reflection module and housing, thereby resolving the interference problem while maintaining the movement capabilities needed for autofocus and optical image stabilization
Solution Approach 2:
The buffer members are pre-installed on the first auxiliary member at positions that anticipate potential interference between the reflection module and housing. These buffer members provide beforehand cushioning by absorbing impacts before they can cause damage to the components, ensuring structural reliability during the dynamic operations of autofocus and optical image stabilization
2Reliability
If the reflection module is designed to rotate about two perpendicular axes for optical image stabilization, then stabilization performance is improved, but the complexity of the holder structure increases
Solution Approach 1:
The holder structure is segmented into functional components: a rotation holder for rotating about the second rotation axis, a reflection holder mounted on the rotation holder for rotating about the first rotation axis, and a first auxiliary member coupled to the rotation holder. This segmentation allows each component to perform its specific function while reducing overall structural complexity
Solution Approach 2:
The first auxiliary member serves multiple functions: it supports the buffer members for impact absorption, provides structural connection between the rotation holder and housing, and maintains proper spacing between components. This multi-functionality reduces the need for additional separate components, thereby reducing overall device complexity
