Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dedicated hardware is used for various biological signal processing tasks, then measurement precision and reliability are improved, but device complexity and cost increase
Solution Approach 1:
The system divides the monitoring device into separate functional modules: sensor assemblies for signal acquisition, a body unit for basic processing and display, and optional external processing units. This segmentation allows each component to be optimized independently while reducing overall system complexity.
Solution Approach 2:
The body unit is designed as a universal platform that can work with multiple types of sensor assemblies (ECG, SpO2, NIBP, temperature) and can be configured for different monitoring scenarios. The standardized interface and modular architecture enable one device to perform multiple monitoring functions.
2Measurement precision
If all signal processing functions are integrated in one device, then measurement precision is improved, but portability and ease of operation deteriorate
Solution Approach 1:
The monitoring system is divided into portable body unit and optional external processing components. The body unit contains essential functions for immediate monitoring, while advanced processing can be performed externally, enabling portability without sacrificing processing capability.
Solution Approach 2:
The body unit acts as an intermediary between the sensors and external processing systems or remote monitoring stations. It performs preliminary signal conditioning and can operate independently or in conjunction with external devices, providing flexibility in deployment scenarios.
3Measurement precision
If comprehensive signal processing capabilities are built into the body unit, then measurement precision is improved, but the processing burden on the body unit increases
Solution Approach 1:
Processing functions are segmented between the body unit and external processing units. The body unit handles essential real-time processing, while complex analysis can be performed externally, distributing the processing burden and reducing the complexity of the portable device.
