Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing centroid adjustment mechanisms are used, then the pan-tilt-zoom can support various cameras, but the adjustment speed is slow and precision is low
Solution Approach 1:
The patent replaces traditional mechanical adjustment mechanisms with an electric drive system comprising motors, lead screws, and sliding blocks. This substitution enables faster and more precise centroid adjustment through electronic control, directly resolving the contradiction between slow adjustment speed and low precision in existing mechanical systems.
Solution Approach 2:
The patent introduces three-dimensional adjustment capabilities along X, Y, and Z axes with independent motors for each direction. By adding degrees of freedom and using scalable parameters (adjustment range, precision, speed), the system achieves both high-speed and high-precision centroid adjustment, resolving the contradiction between speed and precision.
2Measurement precision
If traditional adjustment mechanisms are used, then the structure is simple, but the adjustment precision and speed are insufficient
Solution Approach 1:
The patent divides the centroid adjustment mechanism into three independent modular systems for X, Y, and Z axes. Each axis has its own motor, lead screw, and sliding block assembly. This segmentation allows for precise control of each dimension while maintaining manageable system complexity through standardized modular components.
Solution Approach 2:
The patent introduces lead screws as intermediary elements between the motors and the camera mounting platform. The lead screws convert rotational motor motion into precise linear displacement, enabling high-precision adjustment without requiring complex direct-drive mechanisms, thus balancing precision requirements with acceptable system complexity.
3Productivity
If existing mechanisms are used, then the device is compact, but the adjustment capability is limited
Solution Approach 1:
The patent designs a universal centroid adjustment mechanism that can accommodate various camera types and weights through standardized motor mounts and adjustable ranges. The three-axis system provides multi-functional capability for positioning cameras in any direction within the adjustment range, enhancing productivity while maintaining reasonable complexity through standardized components.
Solution Approach 2:
The patent employs dynamically controllable motors that can adjust speed, torque, and positioning precision based on real-time requirements. The system transitions from static mechanical linkages to dynamic electrically-controlled actuation, enabling rapid repositioning and high-speed adjustment while keeping the physical structure relatively compact through controlled motion profiles.

AI summary
The present application relates to the technical field of photographing devices, and provides a centroid adjustment mechanism of a pan-tilt-zoom camera, a pan-tilt-zoom, and an aerial vehicle. The centroid adjustment mechanism includes: a camera base provided on a pan-tilt-zoom, and a slide platform located below the camera base, and further including: an X axis direction centroid adjustment mechanism, a Y axis direction centroid adjustment mechanism, and a Z axis direction centroid adjustment mechanism that adjust a camera centroid in three directions in a working manner of meshing a gear with a rack. The centroid adjustment mechanism of the pan-tilt-zoom camera can respectively perform centroid adjustment according to centroid adjustment requirements of different cameras in three directions of an X axis direction, a Y axis direction, and a Z axis direction, and rotate knobs in the three directions to drive a gear to mesh with a rack in the three directions, so that adjustment is quick and accurate.
