Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional optical anti-shake components are used, then image clarity is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges the lens component and connection components into an integrated assembly where the lens component is directly connected to the module bracket through multiple connection components. This integration eliminates the need for separate, complex optical anti-shake mechanisms while maintaining image stability through the coordinated movement of the simplified connection components.
Solution Approach 2:
The connection component is segmented into multiple independent elements (first connection component, second connection component, third connection component) that can move relative to each other. Each connection component includes sliding portions and fitting portions that enable independent movement, allowing the system to achieve anti-shake functionality through distributed, simplified movements rather than a single complex mechanism.
2Reliability
If traditional optical anti-shake components are used, then image clarity is improved, but assembly difficulty increases
Solution Approach 1:
By integrating the connection components directly into the lens assembly structure, the patent reduces the number of separate parts that need to be assembled. The connection components are positioned and connected in a straightforward manner, with sliding portions fitting into corresponding fitting portions, simplifying the assembly process compared to traditional multi-component anti-shake systems.
Solution Approach 2:
The connection components are designed with self-aligning features where sliding portions automatically fit into corresponding fitting portions during assembly. The geometric relationships between components (such as the acute angles between extension directions) enable self-positioning, reducing the need for complex alignment procedures and specialized assembly tools.
3Reliability
If connection components are arranged with acute angles relative to optical axis, then anti-shake effect is achieved, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies different geometric configurations to different parts of the connection system. The first fitting portion and second fitting portion have specific angular relationships (acute angles) optimized for anti-shake performance, while other portions maintain simpler geometries. This localized optimization allows the critical anti-shake function to benefit from precise angular relationships without requiring high precision throughout the entire manufacturing process.
Solution Approach 2:
The connection components are designed with asymmetric geometric relationships, where the extension directions of fitting portions form acute angles rather than symmetric right angles. This asymmetric configuration is specifically optimized to generate the necessary counterbalancing movements for anti-shake functionality, achieving the desired effect with manageable manufacturing tolerances.
