Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If medical data is transmitted over mobile devices with limited bandwidth and intermittent connections, then accessibility and mobility are improved, but transmission reliability and data completeness deteriorate
Solution Approach 1:
The system pre-processes and prioritizes medical data before transmission, preparing critical data for immediate delivery while buffering less critical data. This preliminary organization ensures that when connections are available, the most important data is transmitted first, maintaining reliability despite intermittent connectivity.
Solution Approach 2:
The system continuously monitors transmission status and connection quality, adjusting data prioritization and transmission parameters in real-time based on feedback from network conditions. This feedback mechanism ensures reliable data delivery by adapting to changing network conditions and prioritizing critical data during poor connectivity.
2Quantity of substance
If comprehensive patient data is displayed on mobile devices with small screens, then information completeness is improved, but display readability and usability deteriorate
Solution Approach 1:
The system segments patient data into hierarchical categories with different levels of detail. Critical information is displayed prominently at the top level, while additional detailed information can be accessed through expansion or drill-down functions. This segmentation allows comprehensive data to be presented in a readable, organized manner on small screens.
Solution Approach 2:
The system uses multiple display dimensions including vertical arrangement of critical data, horizontal organization of related parameters, and temporal sequencing of waveform displays. This multi-dimensional presentation allows comprehensive information to be displayed effectively on limited screen real estate by utilizing space in multiple directions.
3Loss of time
If real-time waveform data is continuously updated and displayed, then clinical decision-making timeliness is improved, but data processing load and device performance requirements worsen
Solution Approach 1:
The system extracts and prioritizes only the most critical real-time data elements for immediate display, such as vital signs thresholds and alarm conditions, while maintaining the capability to access complete waveform data when needed. This extraction reduces the immediate processing load on mobile devices while preserving timely clinical decision-making capability.
Solution Approach 2:
The system dynamically adjusts the level of real-time data processing and display based on current clinical conditions and device capabilities. During critical events, the system increases processing priority for real-time data; during stable periods, it reduces processing intensity. This dynamic adaptation balances timeliness requirements with device performance constraints.
