Insulin Infusion Mode Switching With User-Configurable Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulin infusion systems lack user-configurable notifications and fail to adapt to individual user preferences, potentially disrupting sleep by continuously operating in closed-loop mode without considering user-specific alert configurations.
Innovation Solution
Implementing a user-configurable notification system that allows users to customize alert settings, including notification type, frequency, and response mechanisms, and adapts insulin delivery mode based on user input, such as updated blood glucose measurements, to ensure safe and personalized operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous closed-loop insulin infusion control is implemented, then blood glucose regulation is improved, but user sleep is disrupted due to lack of customizable notifications
Solution Approach 1:
The system dynamically transitions between closed-loop and open-loop operational modes based on user interaction. When the user responds to a notification by providing manual blood glucose data, the system switches from autonomous closed-loop control to open-loop mode, allowing the user to resume control and avoid sleep disruption while maintaining glucose regulation capability.
Solution Approach 2:
The system implements a feedback mechanism where notifications are sent to the user when sensor data is unavailable or out of range. The user's response to these notifications provides feedback that triggers mode switching, enabling the system to adapt its control strategy based on user needs and preferences.
2Measurement precision
If closed-loop mode operates autonomously without user input, then glucose control precision is improved, but user preference adaptation is reduced
Solution Approach 1:
The system dynamically adjusts its operational mode based on user responses. It transitions from autonomous closed-loop control to user-controlled open-loop mode when users provide manual measurements, allowing the system to adapt to individual user preferences while maintaining precise glucose control capability when needed.
Solution Approach 2:
The system changes its operational parameters by switching between closed-loop and open-loop modes. This parameter change allows the system to balance autonomous precision control with user preference adaptation, enabling users to choose their level of involvement in the glucose management process.
3Measurement precision
If sensor data monitoring is continuous, then glucose level accuracy is improved, but system complexity increases due to multiple operational modes
Solution Approach 1:
The system segments its operational logic into distinct modes (closed-loop and open-loop) with clear transition criteria. This segmentation simplifies the overall system architecture by creating well-defined operational states and transition rules, making the complexity manageable while maintaining continuous monitoring capability for accurate glucose level measurement.
