Innovation Solution
A method utilizing a first rotation to revolve an object and a second rotation by a separate device, enabling high-speed imaging from multiple angles through a system comprising a first circular plate with a second circular plate performing a distinct rotational motion, equipped with an imaging unit to capture side surfaces, and additional units for fixation, recovery, and classification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single rotation method is used to image three-dimensional objects, then the imaging apparatus structure is simple, but the imaging efficiency is low and mechanical defects occur
Solution Approach 1:
The patent divides the rotation function into two separate circular plates: a first circular plate that rotates to position objects at different angular locations, and a second circular plate that rotates to rotate objects themselves. This segmentation allows each plate to perform a specialized rotation function, improving overall imaging efficiency while avoiding the mechanical complexity of a single complex rotation mechanism.
Solution Approach 2:
The patent introduces a second rotation dimension by adding another circular plate that rotates independently. The first circular plate handles angular positioning (first dimension), while the second circular plate handles object rotation (second dimension). This dimensional separation enables high-speed imaging from multiple angles without the mechanical conflicts of a single rotation system.
2Reliability
If electronic methods are used for object handling, then operation precision is high, but electronic errors occur during high-speed imaging
Solution Approach 1:
The patent replaces electronic control methods with a purely mechanical rotation system. The dual circular plate mechanism uses mechanical rotation to position and rotate objects for imaging, eliminating electronic controllers, sensors, and software that could cause errors during high-speed operation. This mechanical approach provides reliable, error-free object handling while maintaining precise control through mechanical geometry.
3Speed
If a single rotation drive is used, then the device structure is simple, but high-speed imaging from multiple angles cannot be achieved
Solution Approach 1:
The patent segments the rotation function into two independent circular plates, each capable of rotating at high speeds. The first circular plate rapidly positions objects at different angular locations, while the second circular plate rapidly rotates objects for multi-angle imaging. This segmentation enables high-speed imaging from multiple angles by distributing the rotation tasks across two simpler, faster-rotating components rather than one complex slow-rotating mechanism.
