Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual tracking method is used, then device complexity is reduced, but measurement precision and reliability of inventory data deteriorate
Solution Approach 1:
The patent replaces manual tracking mechanisms with automated sensor-based detection systems. RFID tags and sensors automatically detect and track medical instruments, eliminating the need for manual counting and recording. This substitution of mechanical/manual systems with automated electronic systems resolves the contradiction by improving measurement precision while the modular architecture keeps device complexity manageable.
2Reliability
If automated sensor-based tracking system is implemented, then measurement precision and reliability improve, but device complexity increases
Solution Approach 1:
The tracking system is segmented into independent modular components: RFID tags attached to instruments, sensors placed in storage areas, communication modules, and software processing systems. Each component performs a specific function and can be independently deployed or replaced. This segmentation allows the system to achieve high reliability through comprehensive coverage while managing complexity through modularity and standardized interfaces.
3Loss of information
If comprehensive instrument tracking is implemented, then loss of information is reduced, but loss of time for system setup increases
Solution Approach 1:
The system performs preliminary actions by pre-attaching RFID tags to all medical instruments before they enter circulation, and by pre-positioning sensors in all storage locations. This preliminary setup creates an immediate tracking capability from day one, reducing information loss without requiring time-consuming system configuration during actual use. The cloud-based architecture also enables rapid deployment by eliminating complex local infrastructure setup.
