Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If three-dimensional medical data is displayed on a two-dimensional interface, then the system can process and display volumetric images, but the accuracy of visualizing and navigating medical devices is reduced
Solution Approach 1:
The patent applies dimensionality change by rendering three-dimensional medical data and medical device poses on a two-dimensional display interface. The system projects 3D volumetric images and device trajectories onto 2D screens, allowing surgeons to visualize spatial relationships and navigation paths while maintaining the complexity reduction benefit of simpler display hardware.
2Measurement precision
If multiple sets of medical data are displayed with varying transparencies and colors, then the context and accuracy of needle insertion points are improved, but the display complexity and processing requirements increase
Solution Approach 1:
The patent utilizes color changes and transparency variations to encode multiple sets of medical data differently. By assigning distinct colors and transparency levels to various anatomical structures and device trajectories, the system enables clear differentiation and contextual understanding without requiring separate display interfaces, thus managing complexity while maintaining information richness.
Solution Approach 2:
The system segments medical data into multiple independent datasets (anatomical structures, device trajectories, target zones) and displays them with different visual properties. This segmentation allows selective rendering and processing of each data type, optimizing the balance between information completeness and processing complexity.
3Manufacturing precision
If the system analyzes volumetric medical images to determine optimal needle insertion points, then the precision of medical device placement is improved, but the processing time and computational resources increase
Solution Approach 1:
The patent applies preliminary action by pre-processing volumetric medical images to identify anatomical structures, target zones, and safe pathways before the actual surgical procedure. The system analyzes and segments medical data in advance, creating a database of optimal insertion points and trajectories that can be quickly referenced during surgery, thus reducing real-time processing requirements while maintaining high placement precision.
