Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional contour line modification methods are used, then the interface complexity is reduced, but the precision and efficiency of contour line modification deteriorates
Solution Approach 1:
The patent introduces touch points as intermediary elements between the user and the contour line. These touch points serve as mediators that capture user input gestures and translate them into precise contour line modifications. The touch points bridge the gap between simple touch input and complex contour manipulation, enabling high precision modification without requiring a complex interface.
Solution Approach 2:
The patent replaces traditional mechanical or manual contour line drawing tools with a gesture-based touch input system. Instead of using complex drawing tools or manual point-by-point adjustment mechanisms, the system substitutes these with direct touch gestures that naturally capture user intent. This substitution simplifies the interface while maintaining or improving modification precision through gesture recognition and curvature calculation algorithms.
2Productivity
If manual point-by-point contour adjustment is used, then the interface simplicity is maintained, but the time consumption and productivity deteriorates
Solution Approach 1:
The patent performs preliminary actions by automatically generating initial contour lines through image processing and lesion detection before the user interaction stage. This preliminary contour generation provides a head start, reducing the amount of manual adjustment needed. Additionally, the system prepares touch point data structures and movement tracking mechanisms in advance, enabling rapid response to user gestures without computational delays during the actual modification process.
Solution Approach 2:
The patent implements continuous useful action through gesture-based touch input that allows users to modify multiple contour line points simultaneously in a single continuous motion. Instead of requiring discrete, sequential point adjustments, the system captures continuous touch gestures and applies modifications along the entire gesture path. This continuity eliminates idle time between adjustments and maintains productive action throughout the interaction, significantly reducing total modification time.
3Measurement precision
If complex algorithms for curvature calculation are used, then the contour line accuracy is improved, but the computational complexity and processing time worsens
Solution Approach 1:
The patent segments the contour line modification process into distinct computational stages: touch point data collection, movement path tracing, curvature calculation, and contour line generation. By dividing the algorithm into these modular segments, each handling a specific aspect of the modification process, the system achieves high accuracy through specialized calculations in each segment while keeping individual algorithmic complexities manageable. The segmentation allows for optimized computation in each stage without requiring the entire system to handle maximum complexity simultaneously.
