Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation is used to position and rotate the digital device, then the device can be positioned to capture images, but the speed of image capture is reduced and human intervention is required
Solution Approach 1:
The motorized mount system automatically positions and rotates the digital device without requiring manual operation. The motor drives the rotational component to orient the device toward different directions, and the system self-regulates to capture images at predetermined intervals or positions, eliminating the need for continuous human intervention and significantly increasing capture speed
Solution Approach 2:
The patent replaces manual mechanical positioning with an automated motor-driven system. The motor converts electrical energy to mechanical rotation, automatically adjusting the device orientation instead of requiring manual manipulation, thereby increasing both speed and consistency of image capture operations
2Measurement precision
If the camera is not positioned at the no-parallax point, then the device structure is simpler, but parallax errors occur in captured images
Solution Approach 1:
The system pre-calculates and pre-positions the digital device at the no-parallax point before image capture begins. The motorized mount is configured in advance to rotate the device around an axis that passes through the camera's optical center, ensuring that all subsequent images are captured from the correct geometric position to eliminate parallax errors
Solution Approach 2:
The motorized mount acts as an intermediary mechanism between the digital device and the imaging environment. It precisely controls the device's orientation and position, ensuring the camera remains at the no-parallax point during rotation, thereby mediating the geometric relationship between the device and the surrounding environment to eliminate parallax distortion
3Measurement precision
If the digital device is manually positioned to capture images from multiple directions, then the capture process can be completed, but the accuracy of 3D visualization is reduced
Solution Approach 1:
The system transitions from static manual positioning to dynamic automated rotation. The motor-driven rotational component continuously or stepwise adjusts the device orientation to capture images from multiple directions with precise angular control, ensuring accurate spatial relationships for 3D reconstruction while eliminating manual repositioning errors
Solution Approach 2:
The motorized mount system incorporates feedback mechanisms to track the rotational position of the digital device. By monitoring the angular position and making real-time adjustments to maintain precise orientation, the system ensures that images are captured from accurately known positions, thereby improving the accuracy of subsequent 3D visualization while reducing manual intervention
