Solution Overview
Problem
Handheld optical products suffer from image blurring due to shaking during operation, leading to unclear imaging and complex, difficult assembly with low product yield.
Innovation Solution
A camera device comprising a lens module, focusing drive module, and anti-shake drive module, each with independent guide and drive assemblies to control lens and image sensor movement, allowing separate assembly and improved alignment for clearer imaging and increased yield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If imaging drive module integrates both focusing and image stabilization functions, then multi-functionality is achieved, but assembly complexity increases and product yield decreases
Solution Approach 1:
The imaging drive module is divided into separate focusing drive assembly and anti-shake drive assembly, each with independent guide structures. The focusing guide assembly includes guide slots and guide blocks, while the anti-shake guide assembly includes separate guide slots and guide blocks, allowing independent assembly and adjustment of each function
2Adaptability or versatility
If imaging drive module integrates multiple functions, then versatility improves, but manufacturing precision requirements increase
Solution Approach 1:
The module is segmented into independent focusing and anti-shake assemblies, each with dedicated guide structures (guide slots and guide blocks), allowing separate manufacturing and quality control for each function
Solution Approach 2:
Independent guide structures act as intermediaries between the drive assemblies and the lens/image sensor, providing precise mechanical guidance and reducing the precision requirements for direct connections between multiple functional components
3Ease of operation
If handheld optical product operates during movement, then usability improves, but image quality deteriorates due to shaking
Solution Approach 1:
The anti-shake drive assembly replaces passive mechanical stabilization with active electromagnetic driving (motor or voice coil), enabling dynamic compensation of hand-held shaking through controlled movement of the image sensor or lens assembly
