Solution Overview
Problem
Existing camera modules in portable electronic devices face challenges in accurately correcting shaking during video recording and tracking moving subjects, requiring users to manually adjust the camera direction, which can be inconvenient and difficult to manage.
Innovation Solution
A folded module with a housing, carrier, and rotation holder featuring intersecting axes for the reflective and lens modules, driven by magnets and coils, allowing for automatic rotation and adjustment of the camera's angle of view to track moving subjects and correct shake, enabling improved image stabilization and video capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera module uses a fixed lens module without rotation capability, then the structure is simple, but it cannot track moving subjects or correct shaking during video recording
Solution Approach 1:
The patent implements a dynamic camera module where the lens module can rotate around an optical axis through a rotation holder with ball members, allowing the imaging direction to change dynamically to track moving subjects and correct shake, transforming a static structure into a dynamic one
Solution Approach 2:
The camera module is divided into separate functional components: a housing, a carrier for the lens module, and a rotation holder with ball members, allowing independent rotation of the lens module while maintaining structural integrity through modular segmentation
2Reliability
If the lens module is directly movable by an actuator, then the structure is simple, but it cannot accurately correct continuous shaking during video recording
Solution Approach 1:
The rotation holder with ball members enables continuous rotational movement of the lens module around the optical axis, allowing dynamic adjustment to accurately track and correct continuous shaking during video recording, rather than relying on direct linear actuation
Solution Approach 2:
The ball members act as intermediaries between the rotation holder and the lens module, enabling smooth rotational movement and accurate positioning of the lens module to correct shaking while reducing direct mechanical contact and friction
3Ease of operation
If the user manually moves the terminal to adjust imaging direction, then no additional components are needed, but it is inconvenient and difficult to accurately capture video footage of moving subjects
Solution Approach 1:
The camera module performs automatic subject tracking and shake correction through its own rotation capability, eliminating the need for manual user intervention to adjust imaging direction, as the system serves itself by dynamically adjusting the lens module orientation
Solution Approach 2:
The dynamic rotation mechanism allows the camera module to automatically adapt its imaging direction in real-time to track moving subjects, providing ease of operation by eliminating manual adjustment requirements
