Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable infusion pumps face challenges in connecting to multiple types of continuous glucose monitoring (CGM) sensors due to differences in communication protocols, parameters, security measures, and overall characteristics among various CGM vendors and versions.
Innovation Solution
The ambulatory infusion pump system is designed with software that stores characteristics for different types of CGM sensors, allowing it to interface with various sensors based on specific requirements, including communication protocols, authentication methods, and data transmission intervals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single portable infusion pump software connects to multiple types of CGM sensors with different communication protocols and characteristics, then compatibility and versatility are improved, but device complexity and software complexity increase
Solution Approach 1:
The patent segments the CGM sensor interface into distinct communication protocol handlers, each dedicated to a specific sensor type (e.g., Dexcom, Libre, Medtronic). This modular segmentation allows the system to manage multiple sensor types through independent, manageable components, reducing overall software complexity while maintaining high versatility.
Solution Approach 2:
The patent implements a universal CGM interface layer that provides a standardized abstraction over multiple sensor types. This universal layer handles common operations (glucose data retrieval, authentication, communication) through a unified interface, allowing the same codebase to work with diverse sensors without requiring separate dedicated software for each type.
2Adaptability or versatility
If the pump system stores and manages characteristics for multiple CGM sensor types, then adaptability is improved, but memory requirements and data management complexity increase
Solution Approach 1:
The patent applies local quality by storing CGM-specific characteristics (communication protocols, authentication methods, data formats) only where needed - within the specific protocol handler modules rather than throughout the entire system. This localized data storage minimizes memory requirements while maintaining comprehensive sensor support.
Solution Approach 2:
The system performs preliminary action by pre-configuring and pre-storing the communication characteristics, authentication credentials, and data formats for supported CGM sensor types in a structured database. This advance preparation allows the system to quickly adapt to different sensors without requiring extensive real-time data processing or storage during operation.
