Solution Overview
Problem
Existing electronic devices suffer from poor anti-shake effects due to user hand-shaking during photography, leading to blurry images.
Innovation Solution
The electronic device incorporates a movable camera module with a first and second driving mechanism, allowing for large-angle and small-angle anti-shake states, and includes an anti-shake micro-gimbal for flexible anti-shake rotation, with a fill light assembly for improved image clarity in dark environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera module is fixedly provided in the electronic device, then the device structure is simple, but the anti-shake effect is poor due to user hand-shaking
Solution Approach 1:
The camera module is transformed from a fixed structure to a movable one, enabling it to rotate around first and second axes that are non-parallel and non-perpendicular. This dynamic positioning capability allows the camera to compensate for hand-shaking movements, improving anti-shake effect while maintaining reasonable structural complexity
Solution Approach 2:
The camera module is divided into independent rotational degrees of freedom around two different axes, allowing separate control and adjustment of shooting angles. This segmentation enables precise anti-shake compensation by adjusting each axis independently based on detected shaking movements
2Adaptability or versatility
If the camera module is made movable to achieve large-angle anti-shake, then the anti-shake compensation angle is improved, but the device structure becomes more complex
Solution Approach 1:
The camera module is designed to serve multiple functions: it acts as both a fixed camera for normal shooting and a movable camera for anti-shake compensation. The same module can rotate around two different axes to achieve both wide-angle shooting and anti-shake compensation, reducing the need for additional dedicated components
Solution Approach 2:
The camera module is enabled to move from a single-plane rotation to multi-dimensional rotation around two non-parallel axes. This dimensional expansion allows the camera to compensate for shaking in multiple directions simultaneously, achieving larger anti-shake compensation angles without proportionally increasing structural complexity
3Area of moving object
If the camera rotates around two non-parallel and non-perpendicular axes, then the shooting field of view is improved, but the mechanical structure becomes more complex
Solution Approach 1:
The two rotation axes are deliberately designed to be non-parallel and non-perpendicular, creating an asymmetric rotational configuration. This asymmetric arrangement expands the shooting field of view by allowing the camera to access angles that would be unavailable with orthogonal axes, while the complexity is managed through integrated driving mechanisms
