Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If FLIP measurement data is displayed using traditional methods, then the data can be viewed, but the visualization is not informative enough for clinicians and researchers
Solution Approach 1:
The patent segments FLIP measurement data into multiple visual representations including heatmaps, topographs, and segmented luminal diameter displays. Each visualization type segments different aspects of the data (spatial distribution, magnitude, anatomical boundaries) to provide comprehensive information without overwhelming the user with raw data complexity
Solution Approach 2:
The patent transforms 1D pressure and diameter measurements into 2D heatmaps and topographs by adding spatial dimensions. The heatmaps display magnitude through color intensity across the probe surface, while topographs add elevation information to create three-dimensional visualizations from two-dimensional data, significantly increasing information density without proportionally increasing software complexity
2Adaptability or versatility
If comprehensive FLIP data analysis features are implemented, then the analytical capability is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent implements a universal software platform that handles multiple analysis functions (heatmap generation, topograph creation, luminal segmentation, parameter calculation) within a single integrated system. The software automatically adapts to different FLIP datasets and analysis requirements, providing versatile analytical capabilities through standardized interfaces that maintain ease of operation
Solution Approach 2:
The software performs automatic luminal segmentation and parameter extraction without requiring manual intervention. The system self-adjusts visualization parameters and automatically identifies anatomical structures, reducing the operational burden on users while providing comprehensive analytical capabilities
3Loss of information
If detailed parameter values are displayed for all regions, then the information completeness is improved, but the visual clarity deteriorates
Solution Approach 1:
The patent applies local quality by displaying different types of information in different visual regions. Heatmaps use color intensity to represent magnitude locally across the probe surface, while numerical parameter values are displayed only in specific regions or upon user interaction. This allows complete parameter information to be available without overwhelming the entire visual field, maintaining clarity while preserving information completeness
Data Source
AI summary
A method for analyzing and displaying functional lumen imaging probe (FLIP) measurement data includes receiving FLIP measurement data. A heatmap or topograph of the measurement data is generated and displayed to thereby create an image of a diameter along the lumen. The image is segmented to display only diameters of the lumen within a range of diameter values specified by a user.
