Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-function pulse diagnostic device is used to obtain pulse information from one artery, then the device structure remains simple, but the comprehensiveness of pulse characteristics analysis is limited
Solution Approach 1:
The diagnostic device is designed to measure pulse information from multiple arteries (radial artery, ulnar artery, and carotid artery) using a unified measurement principle and integrated system architecture. The device incorporates multiple sensors that can detect pulse waves from different arterial locations, enabling comprehensive analysis of pulse characteristics including position, rate, width, and trend across multiple arteries simultaneously, thus achieving multi-functionality without proportionally increasing system complexity
2Measurement precision
If pulse information is obtained from multiple arteries, then the accuracy of physiological information and health evaluation is improved, but the device complexity increases
Solution Approach 1:
The diagnostic device employs separate, independent sensors for measuring pulse information from different arteries (radial artery sensor, ulnar artery sensor, and carotid artery sensor). Each sensor independently captures pulse wave characteristics from its target artery, and the control system processes each signal separately before integrating the results. This segmentation approach allows accurate multi-artery measurement while maintaining manageable device complexity through modular sensor design and independent signal processing channels

Data Source
AI summary
A pulse diagnostic device and a system of pulse diagnosis are provided. The pulse diagnostic device includes a cuff and a main monitor. The cuff includes a tube and an air bag arranged with an air path interface. A gas medium is received in the air bag. The tube is connected to the air path interface. The main monitor includes a pressure sensor and a controller. The tube extends to reach the main monitor and is connected to the pressure sensor, and the pressure sensor further connects to the controller. When the pulse diagnostic device is working, the cuff contacts an artery, the pressure sensor senses a pressure of the gas medium in the tube. The pressure sensor transmits the pressure of the gas medium to the controller. The controller obtains the pulse information and the blood pressure information based on the pressure of the gas medium.
