Solution Overview
Problem
Conventional sphygmomanometers lack variability and cannot convert human blood flow data into comprehensive health information, leading to inaccurate pulse condition measurements when using a single detector.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single detector is used to measure both blood pressure and pulse condition, then the device complexity is reduced, but the measurement precision of pulse condition deteriorates
Solution Approach 1:
The patent divides the detection function into two separate detectors: a pressure sensor for blood pressure measurement and a pulse sensor for pulse condition measurement. This segmentation allows each detector to specialize in its specific measurement task, improving measurement precision while the integrated controller coordinates both functions to manage overall device complexity.
2Ease of manufacture
If a single detector is used to measure both blood pressure and pulse condition, then the manufacturing cost is reduced, but the reliability of measurement data deteriorates
Solution Approach 1:
The patent employs separate pressure and pulse detectors to ensure reliable measurement data for each parameter. While this increases manufacturing cost compared to a single detector, it significantly improves the reliability and accuracy of measurement data, which is critical for medical diagnostics.
3Device complexity
If only a single detector is used, then the device structure is simplified, but the adaptability of the device deteriorates
Solution Approach 1:
The patent creates a multi-functional device that can measure both blood pressure and pulse conditions through separate specialized detectors. The integrated controller coordinates both measurement functions, allowing the device to adapt to different measurement needs and provide comprehensive health monitoring capabilities.
