Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple fluid circuit with pump is used to simulate blood flow, then the device complexity is reduced, but the realism of physiological responses (such as adrenaline output, heart rate variation) is insufficient
Solution Approach 1:
The pump unit is designed to dynamically adjust its operating parameters (flow rate, pressure, pulse frequency) in real-time based on detection device inputs and predefined scenarios, transforming a static fluid circuit into a dynamic simulation system that can respond to surgical interventions and mimic physiological changes
Solution Approach 2:
Detection devices are integrated into the training model to monitor fluid flow, pressure, and pump operation in real-time, providing feedback signals that enable the system to automatically adjust pump parameters and simulate realistic physiological responses without requiring complex manual control
2Ease of operation
If fixed pump parameters are used, then the ease of operation is improved, but the adaptability to different training scenarios and patient anatomy is reduced
Solution Approach 1:
The system incorporates multiple predefined scenarios with different pump parameters (flow rates, pressures, pulse frequencies) that can be selected and adjusted to match different training objectives, patient anatomies, and surgical conditions, allowing the same device to adapt to various training needs without manual reconfiguration
Solution Approach 2:
The pump unit transitions from static fixed parameters to dynamic adjustable parameters controlled by the electronic control unit, enabling real-time adaptation to different training scenarios while maintaining ease of operation through automated control based on detection device feedback
3Device complexity
If no detection device is integrated, then the device complexity is reduced, but the ability to monitor and respond to surgical interventions in real-time is lost
Solution Approach 1:
Detection devices are integrated to monitor fluid flow, pressure, and pump operation in real-time, providing feedback signals that enable the system to automatically adjust pump parameters and simulate realistic physiological responses to surgical interventions, thereby enhancing training efficacy through responsive feedback mechanisms
