Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As mobile devices trend towards miniaturization and higher performance, enhancing the driving force of optical element driving mechanisms while maintaining their compact size has become a key focus of further development.
Innovation Solution
The optical element driving mechanism includes a movable portion connected to an optical element, a fixed portion, and a driving component with two electrically independent driving portions. These driving portions, each comprising a driving magnetic element, a driving coil, and a magnetically permeable element, work together to provide greater driving force for the movable portion, allowing it to move relative to the fixed portion along the optical axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the driving force of the optical element driving mechanism is enhanced, then the driving performance is improved, but the size of the mechanism increases
Solution Approach 1:
The patent combines two driving portions into a single integrated driving component, where the first driving portion and second driving portion are electrically independent but work together to drive the movable portion. This merging approach allows the system to achieve enhanced driving force through dual driving portions while maintaining a compact structure by integrating them into one unified component rather than using two separate mechanisms.
Solution Approach 2:
The driving component is segmented into two electrically independent driving portions, each capable of independently driving the movable portion. This segmentation allows for enhanced driving force through parallel operation of two portions while maintaining compactness by integrating them within a single component structure, avoiding the need for two separate driving mechanisms.
2Volume of moving object
If the size of the optical element driving mechanism is reduced, then the device miniaturization is achieved, but the driving force is weakened
Solution Approach 1:
The patent merges two driving portions into one integrated driving component that fits within a compact structure. This combining approach enables the mechanism to maintain a small size while achieving enhanced driving force through the coordinated operation of the two electrically independent driving portions, effectively resolving the trade-off between miniaturization and driving force.
Solution Approach 2:
The patent arranges the two electrically independent driving portions in a spatial configuration that utilizes three-dimensional space efficiently. By positioning the driving magnetic elements, driving coils, and magnetically permeable elements in a compact three-dimensional arrangement, the system achieves enhanced driving force without increasing the overall footprint of the mechanism, thus maintaining device miniaturization.
