Rotating Optical Module With Piezo Drive for Wider Shooting Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional fixed optical modules in electronic devices limit image-capturing and video-recording functions to predetermined angles, causing edge distortion and a lack of wider shooting angles.
Innovation Solution
An optical system with a movable portion, driven by a piezoelectric driving assembly, allows for broadening the shooting angle through uniaxial or biaxial rotational movements of the optical module using resilient elements and a rotation shaft, aligned with an optical axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed optical module is used, then the device structure is simple, but the shooting angle is limited and edge distortion occurs
Solution Approach 1:
The optical module is transformed from a fixed structure to a movable one, capable of rotating around a rotation shaft. The driving assembly with piezoelectric element dynamically adjusts the optical module's angular position, enabling the system to capture images at various angles while maintaining a single lens configuration, thus resolving the contradiction between adaptability and device complexity
Solution Approach 2:
The optical system is divided into distinct functional components: a fixed portion housing the piezoelectric element and transmission member, and a movable portion containing the optical module. This segmentation allows independent optimization of each component and enables the optical module to rotate freely around the rotation shaft, achieving wider shooting angles without complicating the overall device structure
2Adaptability or versatility
If a traditional wide-angle lens is used, then the shooting angle is broadened, but edge distortion increases
Solution Approach 1:
Instead of using a static wide-angle lens that inherently distorts edge images, the system dynamically adjusts the optical module's orientation angle. By rotating the optical module to different positions around the rotation shaft, the system can capture wide-angle views while maintaining image quality, as each angular position allows the lens to optimize its focal characteristics for that specific direction
3Adaptability or versatility
If multiple lenses are used to achieve wider angles, then the shooting angle is improved, but the device complexity and cost increase
Solution Approach 1:
The system uses a single optical module that can rotate to different angular positions rather than employing multiple fixed lenses. The driving assembly enables this optical module to dynamically adjust its orientation, achieving the functional equivalent of multiple lenses with a single component, thereby reducing device complexity and cost while maintaining the capability to capture images at various angles
Solution Approach 2:
A single optical module serves multiple functions by rotating to different positions, effectively replacing what would traditionally require multiple specialized lenses. This multi-functional design allows one optical component to perform the work of several, simplifying the device structure and reducing the number of parts needed
