Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multiple-degree-of-freedom sensor circuit board is used to connect unmovable and movable parts, then closed-loop stabilization control effect is achieved, but production cost increases and manufacturing process becomes complicated
Solution Approach 1:
The circuit board is divided into a fixed board body and a movable board body that can move relative to each other. The movable board body is connected to the fixed board body through elastic connection structures, allowing independent movement while maintaining electrical connection. This segmentation enables the circuit board to adapt to stabilization movements without requiring complex multiple-degree-of-freedom mechanisms.
Solution Approach 2:
The circuit board transitions from a static rigid structure to a dynamic flexible structure. The movable board body can dynamically adjust its position relative to the fixed board body through elastic deformation, allowing the circuit board to accommodate stabilization movements while maintaining electrical connectivity throughout the stabilization process.
2Reliability
If a multiple-degree-of-freedom sensor circuit board with multi-folding process is used, then stabilization control is achieved, but manufacturing yield decreases
Solution Approach 1:
The circuit board is segmented into fixed and movable parts that can be manufactured separately using conventional processes, then assembled together. This avoids the need for complex multi-folding processes that reduce manufacturing yield, while still achieving the required stabilization control functionality through the relative movement capability of the segmented structure.
3Reliability
If conventional SSS with complicated elastic circuit board manufacturing process is used, then stabilization effect is achieved, but production cost increases
Solution Approach 1:
The circuit board is divided into fixed and movable board bodies that can be manufactured using standard PCB processes, eliminating the need for expensive custom elastic circuit board manufacturing. The segmentation allows each part to be produced conventionally and assembled together, significantly reducing production cost while maintaining stabilization effect.
Solution Approach 2:
Elastic connection structures serve as intermediaries between the fixed and movable board bodies. These simple elastic elements replace the need for complex elastic circuit board manufacturing processes, providing the necessary flexibility and movement capability at low cost through straightforward assembly operations.
4Reliability
If a conventional SSS structure is used, then stabilization control is achieved, but the size of the camera module increases
Solution Approach 1:
The circuit board structure is merged with the stabilization mechanism. The movable board body itself serves as part of the stabilization system, eliminating the need for separate complex mechanisms. This integration reduces the overall volume of the camera module while maintaining effective stabilization control.
Solution Approach 2:
The circuit board adopts a dynamic flexible structure that can move within a compact range, eliminating the need for large mechanical travel distances. The elastic connection structures enable effective stabilization movements within a small volume, reducing the overall camera module size.
