Adapter Segmentation for Container Stability and Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adapters for transferring substances between containers are difficult to handle, lack stability, and often inadvertently change the position of the container, and do not easily accommodate containers of different sizes or allow for filtration.
Innovation Solution
A cup-shaped adapter with a rigid outer body and a connected insert that forms a modular unit, featuring a filter element and a needle-free Luer connector, ensuring stability and compatibility with various container sizes, and allowing for secure filtration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the adapter uses a flexible structure with slits to accommodate different container sizes, then adaptability is improved, but stability and positional accuracy deteriorate
Solution Approach 1:
The adapter is divided into two functional segments: a rigid outer body that provides stable positioning and a flexible insert with circumferential wall that can adapt to different container sizes. The insert can be removed and replaced to accommodate various container dimensions while the rigid outer body maintains stable container positioning throughout the transfer process.
2Stability of the object's composition
If the adapter uses a rigid structure to maintain stability, then stability is improved, but adaptability to different container sizes deteriorates
Solution Approach 1:
The flexible insert is nested within the rigid outer body, allowing the insert to adapt to different container sizes while being contained and supported by the stable rigid structure. This nested configuration enables the inner flexible component to provide adaptability while the outer rigid component maintains overall stability.
3Stability of the object's composition
If the adapter uses a closed rigid structure, then stability and geometry maintenance are improved, but ease of manufacture and assembly deteriorates
Solution Approach 1:
The adapter is segmented into a rigid outer body and a separate flexible insert, allowing each component to be manufactured independently using optimal processes for each material type, then assembled together. This segmentation simplifies manufacturing while maintaining the closed rigid structure's geometric stability.
4Adaptability or versatility
If the adapter includes a filter element, then filtration capability is improved, but device complexity increases
Solution Approach 1:
The filter element is merged with the flexible insert as an integrated component, combining the filtration function with the adaptable sealing structure. This integration adds filtration capability while minimizing additional complexity by incorporating the filter into the existing insert design rather than adding a separate filtration system.

AI summary
An adapter (14) for transferring a substance from a first container (10) into a second container, having a circumferential wall (47) suitable for housing the first container, along which a cannula body (64) extends and by which said cannula body is coaxially surrounded at least in part, said adapter also comprising a hollow cylindrical section (26) connected to the cannula body and connectable to the second container. The cannula body extends with the longitudinal axis thereof perpendicular to one side of a wall (24) running transversely with respect to the circumferential wall and the hollow cylindrical section extends with the longitudinal axis perpendicular to the other side of the wall. The adapter (14) has a cup-shaped outer body (18) having an outer circumferential wall (32) and the wall (24), running transversely to the longitudinal axis of the outer body, which has an insert (46) having the circumferential wall (47).
