Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Withdrawing viscous fluids from containers into syringes is cumbersome and time-consuming, requiring long draw times and posing challenges in maintaining stability during the process.
Innovation Solution
A container adapter system that securely attaches a syringe adapter to a container, allowing the syringe to be connected for fluid withdrawal, featuring a Luer-type lock connection and a component that holds the syringe adapter in place, reducing the number of components a user needs to manage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a syringe is manually held to withdraw viscous fluid from a container, then the fluid can be extracted into the syringe, but the process becomes cumbersome and time-consuming due to the need to stabilize multiple components
Solution Approach 1:
The patent combines the container, syringe adapter, and syringe into a single integrated assembly where the syringe adapter is permanently attached to the container and the syringe is pre-attached to the adapter. This merging eliminates the need for users to manually stabilize multiple separate components during fluid extraction, directly addressing the productivity and ease of operation contradiction.
Solution Approach 2:
The syringe adapter serves as an intermediary component that mediates between the container and the syringe. It is securely attached to the container and provides a stable interface for the syringe, allowing efficient fluid extraction without requiring the user to manually stabilize the connection between container and syringe.
2Reliability
If multiple separate components are used for fluid withdrawal, then flexibility is maintained, but user fatigue increases and the risk of accidental spills or drops increases
Solution Approach 1:
The patent merges the container, syringe adapter, and syringe into a single stable assembly, reducing the number of separate components the user must manage. This integration directly reduces user fatigue and the risk of accidental spills or drops while maintaining the necessary functional flexibility.
3Reliability
If a secure connection mechanism is used to attach the syringe to the container, then leak resistance is improved, but the device complexity increases
Solution Approach 1:
The syringe adapter incorporates a self-service secure connection mechanism with threaded engagement and sealing features that automatically ensure leak-resistant attachment when the syringe is connected to the container. This self-sealing, self-securing mechanism improves connection security without requiring complex additional components or user intervention beyond simple attachment.

AI summary
Apparatus for removably attaching a syringe to a container for extracting fluid therefrom into the syringe, which is particularly beneficial for fluid having a relatively high viscosity. The disclosed container adapter holds a syringe adapter securely therein (the syringe adapter configured for providing a fluid path between a container and a syringe) while also securing the syringe adapter to the container, and provides an attachment point for securely attaching the syringe to the syringe adapter and thus to the container (at least) while the fluid is withdrawn from the container into the syringe. The syringe is removably attached to an end of the syringe adapter during the withdrawal, and a cap is provided that closes entry and exit to this attachment point when the syringe is not in place. The cap preferably attaches to the syringe adapter using a connection that mimics the connection used by the syringe.
