Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional blood flow measurement technology is used, then the measurement can be performed, but the measurement precision is insufficient for early disease diagnosis
Solution Approach 1:
The patent segments the blood flow measurement process into multiple independent measurement components (cross-sectional images at different positions, phase images, blood flow velocity, vessel diameter) that are measured and displayed separately. This segmentation allows each parameter to be optimized independently and provides comprehensive data for more precise early disease diagnosis.
2Loss of information
If multiple images (cross-sectional images, phase images, blood flow information) are displayed simultaneously, then comprehensive blood flow information can be visualized, but the device complexity increases
Solution Approach 1:
The patent merges multiple types of blood flow measurement information (cross-sectional images, phase images, blood flow velocity, vessel diameter) into a single integrated display system. This combining approach allows comprehensive visualization of blood flow characteristics without requiring separate display devices, thus reducing overall system complexity while maintaining information completeness.
3Measurement precision
If cross-sectional images and phase images are associated and displayed synchronously, then accurate blood flow velocity calculation is enabled, but the processing complexity increases
Solution Approach 1:
The patent introduces an intermediary processing system that automatically associates cross-sectional images with corresponding phase images based on positional and temporal parameters. This intermediary layer handles the complex matching and synchronization operations, enabling accurate blood flow velocity calculation while isolating the complexity from the user interface and simplifying the overall system architecture.
