Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If closed loop control systems are implemented for automated insulin delivery, then insulin delivery accuracy is improved, but system reliability deteriorates due to potential sensor and infusion component failures
Solution Approach 1:
The system performs preliminary actions by continuously monitoring glucose levels and predicting future glucose trends before actual hypoglycemic or hyperglycemic events occur. The control algorithm anticipates medication needs and adjusts insulin delivery proactively, preventing extreme glucose levels rather than merely reacting to them.
Solution Approach 2:
The system implements continuous feedback loops where glucose sensor data is constantly fed back to the control algorithm, which then adjusts insulin delivery rates in real-time. This closed-loop feedback mechanism ensures that insulin delivery accuracy is maintained while the system can detect and respond to sensor failures or anomalies through abnormal feedback patterns.
2Measurement precision
If continuous glucose monitoring is performed to enable real-time insulin adjustment, then insulin delivery accuracy is improved, but device complexity increases due to multiple monitoring and control components
Solution Approach 1:
The system achieves multi-functionality by integrating glucose sensing, data processing, control algorithm execution, and insulin delivery control into a unified platform. The single device performs multiple functions including continuous glucose monitoring, predictive analytics, automated insulin dosing calculations, and direct communication with the insulin pump, thereby reducing the need for separate standalone devices.
Solution Approach 2:
The patent combines the glucose monitor, control unit with processing capabilities, and insulin pump interface into an integrated system. By merging these previously separate components into a cohesive unit, the system reduces overall device complexity while maintaining continuous monitoring and automated control functions.
