Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional CAD technology is used to assist diagnosis, then some pathological information can be detected, but the system lacks an intuitive user interface and requires high operator proficiency for accurate diagnosis
Solution Approach 1:
The aorta is segmented into multiple zones (ascending aorta, aortic arch, descending aorta) with each zone independently analyzed and visualized. This segmentation allows the system to provide targeted diagnostic information for specific regions, improving both accuracy and ease of interpretation by breaking down complex anatomy into manageable segments.
Solution Approach 2:
The system transforms 3D aortic geometry into 2D visualization segments that display cross-sectional areas of true and false lumens. This dimensional transformation creates an intuitive visual representation that is easier to interpret while maintaining precise measurement data, resolving the contradiction between measurement precision and ease of operation.
2Measurement precision
If detailed segmentation of aortic zones and lumen measurement is performed, then diagnosis accuracy improves, but processing time and system complexity increase
Solution Approach 1:
The system performs preliminary segmentation of the aorta into standardized zones and pre-calculates reference normal values for each zone before actual diagnosis. This preliminary preparation enables rapid comparison with patient data during the diagnostic process, maintaining high measurement precision while reducing the time required for actual diagnosis.
Solution Approach 2:
The system creates simplified 2D visualization segments that copy essential 3D lumen geometry information in a more efficient format. These visual copies allow rapid assessment of true and false lumen sizes without requiring complex 3D rendering, thus maintaining measurement accuracy while reducing processing time.
3Loss of information
If the system visualizes multiple parameters (true lumen size, false lumen size, reference lumen) for each aortic zone, then diagnostic information completeness improves, but the visualization complexity increases
Solution Approach 1:
The system merges multiple diagnostic parameters (true lumen area, false lumen area, reference lumen area) into a single integrated visualization segment for each aortic zone. This consolidation displays all critical information together in a unified format, maintaining complete diagnostic information while reducing visualization complexity through integrated presentation.
Solution Approach 2:
The visualization segments are designed to universally display multiple parameters simultaneously using a standardized format that can represent different measurements (areas, ratios, deviations from normal) in a consistent manner. This multi-functional visualization approach maintains information completeness while avoiding the need for multiple separate displays.
