Modular Insulin Pump With Sliding Add-On Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional insulin therapy for diabetes involves frequent injections and manual tracking of insulin doses, carbohydrate intake, and blood glucose levels, which can lead to variations in insulin levels and increased complexity for patients, making it difficult to maintain optimal blood glucose control.
Innovation Solution
A modular insulin pump system with a mechanical coupling mechanism and wireless communication ports that allows for the integration of add-on modules, such as activity monitors and blood glucose sensors, to provide real-time data and adjust insulin delivery based on user activity and nutritional intake, enhancing convenience and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional insulin therapy with frequent injections is used, then blood glucose control can be achieved, but patient convenience deteriorates and treatment complexity increases
Solution Approach 1:
The pump device is divided into a main body and separate add-on modules that can be attached or removed. The mechanical coupling allows functional modules (such as activity monitors or blood glucose sensors) to be integrated with the pump, enabling automated insulin delivery based on real-time data while keeping the base device simple and easy to use.
Solution Approach 2:
The pump device is designed with a universal mechanical coupling that can accommodate different types of add-on modules. This allows a single pump device to perform multiple functions - from basic insulin delivery to advanced automated control - by simply attaching different modules, thereby improving convenience without sacrificing blood glucose control reliability.
2Ease of operation
If insulin pump with automated features is used, then convenience is improved, but device complexity increases
Solution Approach 1:
Complex automated features are segmented into separate add-on modules rather than being integrated into the main pump body. This allows the base device to remain simple while advanced features are available through optional modules that can be attached when needed and removed when not required.
Solution Approach 2:
The device complexity is made dynamic through the mechanical coupling system. The pump can transition between a simple basic mode (with only essential functions) and a complex automated mode (with add-on modules attached). This dynamic configuration allows the device to adapt its complexity to the user's needs at different times.
3Device complexity
If manual tracking of insulin doses and carbohydrate intake is required, then device simplicity is maintained, but measurement precision deteriorates
Solution Approach 1:
Add-on modules such as activity monitors and blood glucose sensors provide real-time feedback data to the pump system. This feedback enables automated adjustment of insulin delivery based on actual physiological conditions, significantly improving measurement precision and blood glucose management without requiring complex manual tracking by the patient.
Solution Approach 2:
The automated modules perform self-service functions by automatically monitoring blood glucose levels, tracking activity, and calculating appropriate insulin doses. This eliminates the need for manual tracking while maintaining device simplicity, as the automated functions are contained within optional add-on modules rather than requiring a complex integrated system.

AI summary
This document discusses, among other things, an apparatus comprising a pump configured to deliver a fluid, a wireless communication port, a controller, and a housing to enclose the apparatus. The controller is configured to communicate with a second device via the communication port using an open standard wireless communication protocol. The housing includes a mechanical coupling to slidably engage the second device which includes a second wireless communication port. Slidably engaging the second device positions the first and second communication ports opposite each other to allow communication via the first and second communication ports when slidably engaged.
