Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional training methods (didactic lectures and water drill) are used for ECMO training, then the training is simple to implement, but the training realism and clinical scenario simulation capability are insufficient
Solution Approach 1:
The patent creates a realistic copy of the human patient and ECMO system using a mannequin with synthetic organs, vessels, and circuits that replicate actual clinical anatomy and physiology. This allows trainees to practice on a faithful reproduction without risk to real patients, achieving high training realism while maintaining controlled complexity.
Solution Approach 2:
The training system is divided into separate modular components including the mannequin with embedded organs, external perfusion simulator, fluid pumps, and control systems. This segmentation allows each component to be optimized independently while maintaining overall system functionality, balancing realism with manageable complexity.
2Adaptability or versatility
If a comprehensive simulation system with multiple features (cannulation, arrhythmias, color changes) is developed, then the training versatility improves, but the device complexity increases
Solution Approach 1:
The mannequin system is designed with universal multi-functionality, incorporating multiple synthetic organs, vessels, and circuits that can simulate various clinical scenarios including peripheral vessel cannulation, central venous catheterization, cardiac arrhythmias, and blood color changes. A single integrated system provides diverse training capabilities without requiring multiple separate devices.
Solution Approach 2:
The patent merges multiple simulation functions into a single integrated mannequin system. The synthetic organs, vessels, circuits, fluid pumps, and control systems are combined into one cohesive platform that can simultaneously or sequentially demonstrate various ECMO procedures and clinical emergencies, achieving versatility while consolidating complexity into a unified system.
3Productivity
If no integrated ECMO simulator exists, then individual training components can be simple, but the overall training effectiveness for comprehensive ECMO management is reduced
Solution Approach 1:
The patent combines previously separate training components (mannequin, perfusion simulator, fluid systems, control interfaces) into an integrated ECMO training system. This merger allows trainees to practice comprehensive ECMO management in a single unified platform, improving training efficiency by eliminating the need to switch between multiple separate systems while managing the complexity through systematic integration.
