One-Sided Lens Driving Device Miniaturization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lens driving devices are difficult to miniaturize due to the accommodation of the lens assembly, driving mechanism, and guide mechanism within a predetermined housing, which limits their ability to combine with other lens driving devices for functions like focus adjustment and optical zooming.
Innovation Solution
The lens driving device configuration includes a lens support, a main body, and a driving mechanism provided on one side orthogonal to the optical axis, with a guide mechanism and driving mechanism facilitating forward and backward movement, allowing for miniaturization without additional housing and enabling easy combination with other devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the lens assembly, driving mechanism and guide mechanism are accommodated in a predetermined housing, then the device structure is complete and functional, but the device size cannot be miniaturized
Solution Approach 1:
The patent extracts the housing from the lens driving device, removing the constraint that prevented miniaturization. The main body is designed to directly support the lens support without requiring an additional housing structure, thereby reducing overall device volume while maintaining structural completeness through integrated design
Solution Approach 2:
The patent merges the housing function into the main body structure. The main body simultaneously serves as both the structural support and the housing, eliminating redundant components and reducing device complexity while enabling miniaturization
2Adaptability or versatility
If the driving mechanism and guide mechanism surround the lens assembly on multiple sides, then the lens support is well-supported and guided, but the device cannot be easily combined with other lens driving devices
Solution Approach 1:
The patent segments the support structure by providing the main body only on one side of the lens support in the first direction, leaving the opposite side open. This asymmetric segmentation enables easy combination with other lens driving devices while the guide mechanism ensures lens support stability through proper guidance in critical directions
Solution Approach 2:
The patent applies local quality by concentrating the main body and support structures only where necessary for stability and guidance, rather than surrounding the lens assembly uniformly. The main body is strategically positioned on one side to provide adequate support while maximizing adaptability for combination with other devices
