Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If two-dimensional cross-sectional images are used for device evaluation, then the evaluation process is simple, but the measurement accuracy is insufficient and critical sections may be overlooked
Solution Approach 1:
The patent transitions from two-dimensional cross-sectional images to three-dimensional ultrasonic images, enabling evaluation of the left atrial appendage closure device from multiple angles and planes. This dimensional upgrade allows comprehensive assessment of device compression ratios without missing critical sections, while the system complexity is managed through automated processing algorithms.
2Reliability
If qualitative evaluation methods are used, then the evaluation process is quick, but the reliability of implantation assessment is insufficient
Solution Approach 1:
The patent implements automated quantitative measurement systems that provide objective feedback on device implantation state, including compression ratios and positioning accuracy. This feedback mechanism enhances evaluation reliability by replacing subjective qualitative assessments with precise numerical data, while the automated nature maintains efficiency.
Solution Approach 2:
The patent replaces manual qualitative assessment methods with automated image processing and measurement systems. The mechanical/manual evaluation process is substituted with computer-based algorithms that automatically calculate compression ratios and assess implantation quality, improving both reliability and consistency.
3Measurement precision
If default four cross-sectional images are used for measurement, then the measurement process is straightforward, but sections with abnormal compression may be missed
Solution Approach 1:
By implementing three-dimensional ultrasonic imaging, the system can evaluate the device from multiple planes and angles beyond the fixed four cross-sectional views. This enables comprehensive coverage of all device sections including those with abnormal compression, while automated processing manages the increased data complexity.
