Modular Infusion Pump UI Switching on Docking and Undocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infusion pump systems face challenges in managing the simultaneous infusion of incompatible fluids, requiring modular designs that allow for separate infusion points and timing, but lack efficient data transfer and interface adjustments when coupled or decoupled from control units.
Innovation Solution
A modular infusion pump system that adjusts its behavior and data transfer based on coupling status with a control unit, allowing for enhanced display and input capabilities when docked, and reverting to standalone functionality when detached, with data transfer and alarm management responsibilities allocated between devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pump module has a larger display and user input mechanism, then the functionality is sufficient when detached, but the display space and input mechanism space are limited when coupled to the control unit
Solution Approach 1:
The user interface elements including display and input mechanisms are made dynamically configurable based on the operational mode. When the pump module is coupled to the control unit, the display shows a simplified interface optimized for the control unit's larger display. When detached, the interface automatically transitions to a full-featured mode suitable for standalone operation, thus adapting the UI to match the available hardware capabilities in each context
Solution Approach 2:
Different portions of the user interface are optimized for different locations and contexts. The pump module's display and input mechanisms are configured to provide detailed information and full input capabilities when standalone, while presenting a simplified, control-unit-complementary interface when coupled, ensuring appropriate functionality is available at each location
2Weight of moving object
If the pump module is designed as portable with limited display space, then it is compact and mobile, but detailed information regarding infusion is harder to view when coupled to control unit
Solution Approach 1:
The control unit serves as an intermediary device that complements the pump module's limited display capabilities. When coupled, the control unit's larger display assumes the primary role of showing detailed infusion information, while the pump module's display provides supplementary or simplified information, creating a cooperative information display system that overcomes the portability limitation
3Ease of operation
If the user input mechanism on the pump module is fully functional when detached, then it provides complete control capability in transport mode, but the input mechanism may be redundant or overly complex when coupled to control unit
Solution Approach 1:
The user input mechanism is dynamically activated or deactivated based on coupling status. When the pump module is coupled to the control unit, certain input functions may be restricted or redirected to the control unit's input mechanisms, while maintaining essential pump control capabilities. When detached, the full input mechanism becomes active to provide complete standalone control, thus adapting complexity to operational needs
