Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional imaging and navigation systems are used for procedure planning, then basic imaging capability is provided, but procedural accuracy and real-time guidance are insufficient
Solution Approach 1:
The patent combines multiple imaging modalities (CT, MRI, ultrasound) with navigation systems into an integrated platform. This merging allows simultaneous access to anatomical structures, real-time instrument tracking, and procedural guidance, resolving the contradiction between measurement precision and reliability by providing both high-resolution imaging and continuous navigation feedback
Solution Approach 2:
The system implements real-time feedback through continuous tracking of instrument position and orientation, displaying this information overlaid on anatomical images. This feedback loop enables dynamic adjustment of trajectories and entry points, improving both procedural accuracy and navigation reliability compared to static pre-procedure planning alone
2Measurement precision
If detailed imaging and navigation systems are implemented, then procedural accuracy is improved, but system complexity increases
Solution Approach 1:
The navigation system is designed to support multiple procedure types (neurosurgery, orthopedics, cardiology) and multiple imaging modalities through a single integrated platform. This multi-functionality reduces overall system complexity by avoiding the need for separate specialized systems for each procedure type, while maintaining high trajectory precision through adaptive planning algorithms
Solution Approach 2:
The system incorporates automated features such as automatic registration of imaging data with patient anatomy, automated calculation of optimal trajectories, and real-time tracking without requiring manual intervention for each measurement. This self-service capability reduces operational complexity while maintaining high precision through sophisticated software algorithms
