Optical Element Driving Mechanism for Compact Multi-Scenario Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern electronic devices with image-capturing and video-recording functions require efficient optical element driving mechanisms that can miniaturize volume and stabilize movement while accommodating various usage scenarios, as existing solutions often compromise on size and stability due to multiple blocking portions distributed across movable parts.
Innovation Solution
An optical element driving mechanism featuring a fixed assembly, first and second movable parts, and a driving assembly that uses magnetic elements and coils to drive the movable parts along an axis, allowing independent or coordinated movement to selectively block openings, thereby reducing overall volume and weight while enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple blocking portions are distributed across movable parts, then the optical element driving mechanism can accommodate various usage scenarios, but the volume and weight of the movable parts increase
Solution Approach 1:
The patent divides the blocking function into multiple independent blocking portions (first blocking portion, second blocking portion, third blocking portion) that can be distributed across different movable parts. Each blocking portion can independently perform blocking operations, allowing the system to accommodate various usage scenarios while keeping individual movable part weights manageable through functional segmentation.
2Adaptability or versatility
If multiple blocking portions are distributed across movable parts, then the optical element driving mechanism can accommodate various usage scenarios, but the volume of the movable parts increases
Solution Approach 1:
The patent segments the blocking functionality into multiple separate blocking portions that can be distributed across different movable parts. This segmentation allows each movable part to have a more compact design with smaller volume, while the collective system maintains high adaptability for various usage scenarios through coordinated operation of multiple segmented components.
3Volume of moving object
If a single driving assembly drives multiple movable parts, then the overall volume of the mechanism is reduced, but the complexity of controlling independent movement increases
Solution Approach 1:
The patent merges multiple driving functions into a single integrated driving assembly that can simultaneously drive multiple movable parts (first movable part, second movable part). This combining approach reduces the overall volume of the mechanism by eliminating the need for separate driving assemblies for each movable part, while the driving assembly is designed to handle the control complexity through unified actuation mechanisms.
