Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the camera module is fixedly provided in the electronic device, then the device structure is simple, but the anti-shake effect is poor
Solution Approach 1:
The camera module is transformed from a fixed structure to a movable one, enabling it to dynamically adjust its position and orientation. The movable module includes driving mechanisms that allow the camera to rotate around multiple axes and extend/retract through a through hole, providing active anti-shake capability while maintaining structural simplicity through modular design
Solution Approach 2:
The camera system is divided into separate functional modules: a movable module containing the camera, an anti-shake micro-cloud gimbal, and driving mechanisms. This segmentation allows each component to perform its specific function independently, improving anti-shake effectiveness while keeping the overall structure organized and manageable
2Reliability
If the camera module is made movable with multiple driving mechanisms, then the anti-shake effect is improved, but the device complexity increases
Solution Approach 1:
The movable module is nested within the housing, with the camera module capable of retracting through a through hole into the housing when not in use. The anti-shake micro-cloud gimbal is integrated within the movable module structure, and driving mechanisms are compactly arranged to control movement. This nesting approach reduces overall device footprint and visual complexity while maintaining full anti-shake functionality
Solution Approach 2:
The movable module serves multiple functions: it provides anti-shake capability through rotation around intersecting axes, enables large and small angle adjustments, and allows the camera to extend for shooting and retract for storage. The anti-shake micro-cloud gimbal works in conjunction with the driving mechanisms to provide both passive stabilization and active compensation, making the system highly versatile
3Reliability
If the camera rotates around multiple intersecting axes, then the anti-shake performance is enhanced, but the control complexity increases
Solution Approach 1:
The control system receives real-time feedback about shaking conditions and automatically adjusts the camera's rotation around the first and second axes accordingly. The anti-shake micro-cloud gimbal provides additional feedback for fine-tuning the camera's orientation, enabling precise compensation for hand-shake without requiring complex manual control from the user
