Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a subject simulator with sensors and control devices is added to the perfusion system, then training realism and equipment testing capability are improved, but device complexity increases
Solution Approach 1:
The patent creates a simplified copy of the human circulatory system using a circulatory loop with fluid, sensors, and control devices that mimic physiological parameters. This allows realistic training scenarios without requiring actual patients, resolving the contradiction by providing training effectiveness through a controlled model rather than direct clinical practice.
Solution Approach 2:
The subject simulator serves multiple functions: it trains perfusionists, tests new equipment, demonstrates perfusion processes, and simulates various clinical scenarios including emergencies. This multi-functionality justifies the added device complexity by consolidating multiple training and testing needs into a single integrated system.
2Adaptability or versatility
If more training scenarios and emergency simulations are provided, then perfusionist response capability is improved, but training time and resource consumption increase
Solution Approach 1:
The simulator uses dynamic control devices that can rapidly change system parameters to create different emergency scenarios and physiological states. This allows a wide range of training scenarios to be delivered in a condensed timeframe, improving adaptability without proportionally increasing training duration.
Solution Approach 2:
The system can cycle through different training scenarios and emergency situations in a structured sequence, allowing perfusionists to experience multiple diverse scenarios during a single training session. This periodic delivery of varied scenarios maximizes learning efficiency within available training time.
3Reliability
If new equipment is tested extensively before clinical use, then equipment reliability is improved, but testing time and opportunity cost increase
Solution Approach 1:
The subject simulator enables preliminary testing of new perfusion equipment in a controlled environment before clinical deployment. By performing equipment validation in advance on the simulator, the system reduces the time and risk associated with introducing new equipment into actual patient care settings.
