Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If 2D images are displayed through the imaging system, then the system structure remains simple, but the accuracy of observation and procedure transmission is insufficient
Solution Approach 1:
The patent transitions from 2D image display to 3D stereoscopic image display by adding depth perception through multiple imaging units positioned at different locations. This dimensional change enables operators and assistants to observe procedure parts with enhanced accuracy and spatial understanding, directly resolving the limitation of 2D image observation.
2Productivity
If operators observe through the microscope for a long time, then the procedure can be completed, but operator fatigue increases
Solution Approach 1:
By providing 3D stereoscopic images that convey depth and spatial relationships, the system reduces the time operators need to spend observing procedure parts. The enhanced visual information allows for faster comprehension and decision-making, thereby reducing overall observation time and operator fatigue while maintaining procedure completion efficiency.
3Measurement precision
If a compound eye camera with multiple imaging units is used to provide 3D images, then stereoscopic imaging is achieved, but the synchronization and focus control becomes complex
Solution Approach 1:
The patent combines multiple imaging units into a unified compound eye camera system with integrated control. The control unit coordinates the zoom operations of all imaging units simultaneously, ensuring they maintain proper synchronization and focus relationships. This merging approach achieves accurate 3D imaging while managing the complexity through unified control rather than separate adjustments.
Solution Approach 2:
The system incorporates feedback mechanisms where the control unit monitors the positions and focus states of multiple imaging units during zoom operations. Based on this feedback, the control unit adjusts the zoom operations to maintain proper synchronization and focus relationships, resolving the complexity of coordinated control among multiple imaging units.
4Measurement precision
If the angles of view of multiple imaging units are changed during zoom operation, then the 3D effect is achieved, but the focus between object and lenses becomes incorrect
Solution Approach 1:
The control unit continuously monitors the focus status of each imaging unit during zoom operations and adjusts their angles of view and focus positions in real-time based on feedback signals. This ensures that while 3D effect is achieved through angle variations, the focus between objects and lenses remains accurate through active compensation and coordination.
