Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple elastic members and complex spring structures are used to move the lens barrel for focus and shake compensation, then the image sensor can achieve stable movement and compensation functions, but the device complexity and number of assembly steps increase
Solution Approach 1:
The patent combines multiple elastic members (springs) and the lens barrel support structure into a single integrated spring plate. This spring plate includes a first plate part supporting the image sensor and a second plate part supporting the lens barrel, with elastic members connecting them. By merging these components, the patent reduces the number of separate parts while maintaining the stability and compensation functions, thereby resolving the contradiction between reliability and device complexity.
2Adaptability or versatility
If multiple elastic members are used for moving the lens barrel, then the focus and shake compensation functions are achieved, but the number of assembling steps increases
Solution Approach 1:
The patent integrates multiple elastic members into a unified spring plate structure that performs both focus compensation and shake compensation functions. The spring plate includes integrated components (first plate part, second plate part, and elastic members) that work together to achieve versatile functions while reducing assembly steps, thus resolving the contradiction between adaptability and productivity.
Solution Approach 2:
The spring plate is designed as a multi-functional component that simultaneously provides focus compensation, shake compensation, and structural support. The first plate part supports the image sensor, the second plate part supports the lens barrel, and the elastic members between them enable both types of compensation. This multi-functionality allows a single component to replace multiple separate components, reducing assembly complexity and improving productivity.
3Productivity
If the spring structure is simplified to reduce assembly steps, then the manufacturing efficiency improves, but the operational reliability may be compromised
Solution Approach 1:
The patent simplifies the spring structure by merging multiple elastic members and support plates into a single integrated spring plate, which improves manufacturing efficiency. However, the design maintains operational reliability by carefully engineering the spring plate to include all necessary functional elements: the first plate part for image sensor support, the second plate part for lens barrel support, and the elastic members for compensation. This integration ensures that the simplified structure still performs all required functions reliably.
Solution Approach 2:
The patent changes the structural parameters of the spring plate, such as the arrangement and configuration of the elastic members and plate parts, to optimize both manufacturing efficiency and operational reliability. By adjusting these parameters, the design achieves a balance between simplicity for manufacturing and complexity for function, resolving the contradiction between productivity and reliability.
