Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric information measurement systems are implemented for monitoring living tissues, then health monitoring capability is improved, but device complexity increases
Solution Approach 1:
The system is divided into separate functional modules: a sensor unit for optical measurement, a communication unit for data transmission, and a processing unit for analysis. This segmentation allows each component to be optimized independently while reducing overall system complexity.
Solution Approach 2:
The measurement system is designed to monitor multiple physiological parameters (plethysmogram, pulse rate, blood oxygen saturation) using a single optical measurement platform, enabling multi-functional health monitoring without proportionally increasing complexity.
2Ease of operation
If wireless transmission of plethysmogram data is implemented, then ease of operation is improved, but energy consumption increases
Solution Approach 1:
The wireless transmission is performed periodically rather than continuously, with the sensor unit transmitting plethysmogram data at intervals or when significant changes are detected, thereby reducing overall energy consumption while maintaining monitoring effectiveness.
Solution Approach 2:
The system incorporates feedback mechanisms where the processing unit receives transmitted data and sends control signals back to the sensor unit, enabling intelligent power management and transmission optimization based on actual monitoring needs.
3Measurement precision
If real-time monitoring of plethysmograms is implemented, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The sensor unit continuously captures and pre-processes plethysmogram data in real-time, preparing measurement results ahead of time so that when analysis is required, the data is already available, reducing the effective processing time while maintaining measurement precision.

Data Source
AI summary
A wireless plethysmogram sensor unit is capable of obtaining a plethysmogram from a living tissue of a measuring object and of transmitting the plethysmogram to a processing unit outside the wireless plethysmogram sensor unit. The sensor unit includes a light source to emit measuring light into the living tissue and a light receiving element to receive light emerging from the tissue, which is accompanied by pulsation caused by absorption by arteries in the tissue. A memory stores a plethysmogram obtained in accordance with the light received by the light receiving element. A short range wireless communicator transmits the plethysmogram to the processing unit. A power source provides power to other elements in the sensor unit, and a controller controls the elements of the sensor unit.
