Infusion Pump Holder with Segmented Flexible Rigid Materials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user-wearable infusion pumps can be uncomfortable due to rigid materials used in their holders, which may not provide adequate retention, and existing designs often require cumbersome tubing or frequent site changes for medicament delivery.
Innovation Solution
A pump holder combining flexible and rigid materials for improved comfort and secure retention, featuring an adhesive patch, a frame base with a flexible outer perimeter, and rigid pump retention features such as locking projections and guide rails, allowing for secure attachment and easy alignment of the infusion pump.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid materials are used in the pump holder to ensure secure retention, then the retention strength is improved, but the comfort and wearability deteriorate
Solution Approach 1:
The pump holder is divided into distinct functional segments: a flexible frame base for comfort and conformability to body contours, and rigid retention features (locking projections, guide rails, perimeter walls) for secure pump attachment. This segmentation allows each part to optimize its specific function without compromising the other.
Solution Approach 2:
Different regions of the pump holder have different material properties tailored to their specific functions. The frame base uses flexible material for comfort, while the retention features use rigid material for strength. This local differentiation resolves the contradiction by assigning appropriate material qualities to appropriate locations.
2Ease of manufacture
If the pump holder uses a simple design for ease of manufacture, then the manufacturing complexity is reduced, but the retention reliability deteriorates
Solution Approach 1:
Multiple retention functions are merged into an integrated holder structure. The frame base, locking projections, guide rails, and perimeter walls work together as a unified system that provides reliable retention while maintaining reasonable manufacturing complexity through cohesive design.
Solution Approach 2:
The pump holder employs composite construction combining flexible and rigid materials in a single integrated structure. This allows the holder to achieve reliable retention through the rigid features while maintaining ease of manufacture through the flexible base that can be molded to various body contours.
3Ease of operation
If the pump holder is designed to conform to body contours for comfort, then the wearability is improved, but the structural stability deteriorates
Solution Approach 1:
The holder structure is segmented into a flexible conformable frame base and rigid stable retention features. The flexible base adapts to body contours for comfort, while the rigid retention features maintain structural stability for secure pump attachment, resolving the contradiction through functional separation.
