Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the oscillometric method is used in electronic sphygmomanometers, then the device complexity is reduced and ease of operation is improved, but the measurement precision deteriorates with deviations up to 16 mmHg
Solution Approach 1:
The patent combines the oscillometric method (easy operation) with the auscultatory method (high precision) in a single electronic sphygmomanometer device. The device includes both a pressure sensor for oscillometric measurement and a sound sensor for auscultatory measurement, merging two measurement methods to achieve both ease of operation and high measurement precision simultaneously
Solution Approach 2:
The patent introduces a sound sensor as an intermediary component to capture Korotkoff sounds during the oscillometric measurement process. This intermediary enables the device to use the auscultatory method's sound-based detection to correct and improve the precision of the oscillometric method while maintaining the automated operation benefits
2Measurement precision
If the auscultatory method is implemented in electronic sphygmomanometers, then the measurement precision is improved, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent replaces the manual mechanical auscultatory method with an automated electronic system. Instead of requiring a trained operator to listen to Korotkoff sounds through a stethoscope, the device uses electronic sound sensors and signal processing algorithms to automatically detect and analyze the sounds, reducing device complexity and enabling automated operation while maintaining high measurement precision
Solution Approach 2:
The patent implements self-service functionality where the electronic sphygmomanometer automatically performs the auscultatory measurement process without requiring trained operation. The device autonomously detects Korotkoff sounds, processes the audio signals, and determines blood pressure values, eliminating the need for professional training and simplifying operation while maintaining the precision benefits of the auscultatory method
3Measurement precision
