Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the optical element drive mechanism is added to stabilize the optical element, then image quality is improved, but device complexity increases
Solution Approach 1:
The circuit assembly merges multiple circuit elements (first circuit element, second circuit element, third circuit element) into a single integrated structure that provides both auto-focus and optical image stabilization functions. The first connection portion integrates electrical connections between these elements, creating a unified control system that reduces overall device complexity while maintaining comprehensive image stabilization capabilities.
Solution Approach 2:
The drive assembly implements multi-functionality by using the same movable part and drive mechanism to achieve both auto-focus (moving the optical element along the optical axis) and optical image stabilization (moving the movable part relative to the immovable part). This universal approach allows a single mechanism to perform multiple functions, improving image quality without proportionally increasing device complexity.
2Reliability
If the circuit assembly uses multiple connection portions to connect circuit elements, then electrical connectivity is improved, but manufacturing complexity increases
Solution Approach 1:
The circuit assembly is segmented into distinct functional modules: the first circuit element for auto-focus control, the second circuit element for optical image stabilization control, and the third circuit element for sensing. The first connection portion is specifically designed to connect these segmented elements, providing reliable electrical connectivity while allowing each segment to be manufactured and tested independently before final assembly.
