Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple special-purpose monitors are used for processing different sensor data, then measurement precision and diagnostic capability are improved, but device complexity increases
Solution Approach 1:
The host system is designed as a universal platform capable of processing multiple types of cardiovascular sensor data (pressure, flow, temperature, electro-physiological signals) through a single integrated system. The system includes multiple input signal bus interfaces that can accept various sensor types, and modular measurement processing components that can be dynamically integrated to handle different measurement modes, thereby providing comprehensive diagnostic capabilities without requiring multiple separate monitors.
Solution Approach 2:
The system employs modular measurement processing components that can be dynamically integrated into the host system. Each module handles specific measurement functions (pressure processing, flow processing, temperature processing), allowing the system to be segmented into independent functional units that can be selectively activated based on diagnostic needs, thus maintaining precision while managing complexity through modularity.
2Adaptability or versatility
If multiple special-purpose monitors are deployed, then diagnostic versatility is improved, but ease of operation deteriorates due to increased equipment complexity
Solution Approach 1:
The host system provides a unified interface for operating with multiple sensor types and measurement modes. The graphical user interface presents consistent interaction methods regardless of which sensors are connected or which measurement mode is active, thereby maintaining ease of operation while supporting comprehensive diagnostic versatility through single-platform multi-functionality.
Solution Approach 2:
The system dynamically integrates measurement processing components based on which sensors are connected and which diagnostic modes are required. The host system can adapt its configuration in real-time, dynamically loading appropriate processing modules and configuring signal routes, which maintains operational simplicity while providing versatile diagnostic capabilities through adaptive reconfiguration.
3Adaptability or versatility
If multiple monitors are used for different sensor types, then adaptability to different sensor types is improved, but device complexity increases
Solution Approach 1:
The system uses separate input signal bus interfaces for different sensor types (pressure sensors, flow sensors, temperature sensors, electro-physiological sensors), allowing each interface to be optimized for its specific sensor type while maintaining a unified host system. This segmentation enables adaptable sensor integration without proportionally increasing overall system complexity.
Solution Approach 2:
The host system serves as a universal platform that can process signals from multiple sensor types through a single integrated architecture. Rather than requiring separate dedicated systems for each sensor type, the universal host system with its multiple input interfaces and modular processing components provides adaptability to different sensors while consolidating equipment complexity into one system.
