Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional imaging devices are used to obtain image data, then image data can be provided for viewing on a display, but the image data must be registered relative to the patient's anatomy which is complex and time-consuming
Solution Approach 1:
The imaging device determines its own position relative to the patient using an integrated tracking system. The device includes a tracking component that automatically tracks the imaging device's position and orientation, eliminating the need for manual registration procedures while maintaining accurate spatial relationship between the imaging device and patient anatomy
Solution Approach 2:
The imaging device integrates multiple functions including image acquisition, position tracking, and navigation capabilities into a single system. The tracking system works with both the imaging device and surgical instruments to provide comprehensive navigation functionality without requiring separate registration processes
2Measurement precision
If complex registration and tracking processes are used to determine instrument position, then position accuracy can be achieved, but the process becomes cumbersome and inefficient
Solution Approach 1:
The tracking system continuously monitors the position of the imaging device and surgical instruments throughout the procedure. This continuous tracking eliminates the need for repeated registration operations and maintains accurate spatial relationships in real-time, improving both precision and efficiency simultaneously
Solution Approach 2:
The system merges the tracking functions for the imaging device and surgical instruments into a unified navigation framework. By combining these tracking systems, the patent achieves accurate instrument positioning without requiring separate complex registration processes for each component

AI summary
The position of an imaging device can be determined at least in part with a movement portion of the imaging device. The imaging device can be moved relative to the patient to obtain image data of the patient at different perspectives or angles. The image data obtained of the patient can be displayed with a display device at various perspectives and a tracked position of the instrument can be displayed at the appropriate perspective or a selected perspective relative to the image data with the display device based upon a known position of the imaging device.
