Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extracorporeal circulation device is used for oxygen supply, then oxygen delivery capability is improved, but device complexity and time consumption increase
Solution Approach 1:
The invention extracts the oxygenation function from the complex extracorporeal circulation device and concentrates it into a simple infusion solution oxygenation device. Only the essential oxygenation function is retained, while other complex functions are removed, achieving simplified device structure while maintaining oxygen delivery capability.
Solution Approach 2:
The invention segments the oxygen delivery system into independent functional modules: oxygen supply unit, mixing unit, and infusion solution container. This segmentation allows each module to perform its specific function independently, reducing overall system complexity while maintaining reliability.
2Reliability
If extracorporeal circulation device is used for oxygen supply, then oxygen delivery capability is improved, but time consumption increases
Solution Approach 1:
The invention prepares oxygenated infusion solution in advance by pre-mixing oxygen with the infusion solution in the container before actual use. This preliminary preparation eliminates the need for time-consuming on-site oxygenation procedures during medical emergencies.
Solution Approach 2:
The infusion solution oxygenation device is designed to be self-contained and operationally simple, requiring minimal professional intervention. The device automatically controls oxygen supply and mixing processes, reducing the time needed for setup and operation compared to complex extracorporeal circulation devices.
3Reliability
If multiple professionals are required for extracorporeal circulation device, then operational safety is improved, but ease of operation deteriorates
Solution Approach 1:
The device incorporates automatic control mechanisms that self-regulate oxygen supply based on preset parameters. The microprocessor-based control system automatically adjusts oxygen flow rates and mixing ratios, eliminating the need for multiple professionals to manually coordinate complex operations while maintaining safety through automated monitoring.
Solution Approach 2:
The invention implements feedback control through sensors that continuously monitor oxygen concentration and infusion solution flow rates. The control system uses this real-time feedback to automatically adjust oxygen supply, ensuring safe operation with minimal human intervention and simplifying the operational process.
4Device complexity
If oxygen is supplied to infusion solution without pressure control, then simplicity is maintained, but safety deteriorates due to over- or under-oxygenation
Solution Approach 1:
The invention incorporates pressure sensors that continuously monitor the internal pressure of the infusion solution container and provide feedback to the control system. This feedback mechanism automatically adjusts oxygen supply rates to prevent over- or under-oxygenation, ensuring safety while maintaining relatively simple device structure.
Solution Approach 2:
The system dynamically changes oxygen supply parameters based on real-time pressure measurements from the container. When pressure indicates high oxygen concentration, the system automatically reduces oxygen supply; when pressure indicates low oxygen concentration, the system increases supply. This parameter adjustment ensures safety without requiring complex manual control mechanisms.
