Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional rig for multi-camera photographing is used, then multiple cameras can be mounted horizontally, but the angle between cameras cannot be controlled accurately
Solution Approach 1:
The patent applies the dynamics principle by introducing rotational movement plates that can freely rotate in both clockwise and counterclockwise directions around a fixed center base plate. This dynamic structure allows the left and right cameras to be adjusted to various angles relative to the center camera, enabling precise angle control while maintaining operational convenience. The rotational mechanism transforms the static rig structure into a dynamic one that adapts to different photographing requirements.
Solution Approach 2:
The patent segments the rig structure into distinct functional components: a fixed center base plate and separate left/right rotational movement plates. Each plate can be independently adjusted and positioned, allowing precise control of camera angles. This segmentation enables the left and right cameras to be rotated to specific angles (e.g., 45 degrees) relative to the center camera, solving the angle control precision problem while maintaining ease of operation through independent adjustment of each segment.
2Adaptability or versatility
If the angle of view of a camera is changed due to lens specifications, then different lens requirements can be met, but the angle between cameras needs to be controlled again
Solution Approach 1:
The dynamic rotational movement plates allow rapid re-adjustment of camera angles when lens specifications change. Instead of manually repositioning entire camera assemblies, the operator can simply rotate the movement plates to achieve the required angles, significantly reducing the time loss associated with repeating angle control tasks when adapting to different lenses.
Solution Approach 2:
The patent enables parameter changes by allowing the rotation angle of the movement plates to be adjusted according to different lens specifications. When a lens with a different angle of view is used, the rotation angles of the left and right movement plates can be modified accordingly, providing adaptability to various lens requirements while minimizing the time penalty through the ease of rotational adjustment.
3Adaptability or versatility
If a rig for capturing stereoscopic image is used, then two cameras can be mounted, but it cannot capture multi-projection images requiring three or more cameras
Solution Approach 1:
The patent segments the multi-camera system into a fixed center camera module and two independent rotational movement plate modules. This segmentation allows the system to scale from three to five or more cameras by adding or removing movement plates without fundamentally changing the overall structure, enabling multi-projection capability while controlling device complexity through modular design.
Solution Approach 2:
The rotational movement plates serve multiple functions: they can hold single cameras for stereoscopic imaging, multiple cameras for multi-projection imaging, and can be configured in various angular arrangements. This multi-functionality allows the same basic structure to adapt to different imaging requirements, providing versatility for both stereoscopic and multi-projection photography without proportionally increasing structural complexity.
