Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ultrasonic waves are emitted from a single angle, then the imaging process is simple and fast, but the accuracy of blood supply information extraction is low
Solution Approach 1:
The patent divides the ultrasonic imaging process into multiple angle segments, emitting ultrasonic waves from at least two different angles (e.g., 0度和45度) to obtain separate echo data sets. This segmentation allows the system to capture blood supply information from multiple perspectives, improving extraction accuracy while maintaining manageable process complexity through systematic data collection and processing
Solution Approach 2:
The patent introduces an angular dimension to the traditional single-angle ultrasonic imaging approach. By emitting ultrasonic waves from multiple angles and processing echo data in this multi-dimensional angular space, the system achieves more comprehensive blood supply information extraction, transforming one-dimensional single-angle imaging into multi-dimensional multi-angle imaging
2Productivity
If narrow-beam ultrasonic waves are used, then the imaging resolution is high, but the data collection efficiency is low and processing time is long
Solution Approach 1:
The patent changes the beam width parameter from narrow to wide (at least 3 ultrasonic wavelengths), which significantly increases the data collection area and efficiency. This parameter change allows the system to capture blood supply information from a larger region in a single measurement, improving productivity while maintaining sufficient resolution through multi-angle data fusion
Solution Approach 2:
The patent implements continuous data collection from multiple angles with overlapping imaging areas, ensuring that the useful action of blood supply information extraction continues without interruption. The wide-beam approach allows overlapping data regions that can be continuously processed, eliminating the need for repeated narrow-beam measurements and improving overall efficiency
3Measurement precision
If multiple angles are used for ultrasonic emission, then the accuracy of blood flow direction analysis is improved, but the processing complexity and time increase
Solution Approach 1:
The patent segments the blood flow direction analysis into separate angular components, processing echo data from different angles (e.g., 0度和45度) independently before integrating the results. This segmentation allows for systematic and efficient processing of multi-angle data, reducing overall processing time while maintaining high accuracy in blood flow direction analysis
Solution Approach 2:
The patent adds an angular dimension to blood flow direction analysis, transforming one-dimensional single-angle measurement into multi-dimensional multi-angle measurement. By processing data in this additional angular dimension, the system achieves more accurate blood flow direction determination without proportionally increasing processing time, as the angular processing follows a standardized pattern
