Bottle Adapter Sloped Surface Residual Fluid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid transfer systems between pharmacy bottles and syringes often leave residual fluid due to the design of current adapters, which prevents the complete withdrawal of contents, typically ranging from 0.50 g to 1.50 g.
Innovation Solution
A bottle adapter connector with a cylindrical body, a recess, and a male coupling that includes a conduit, where the male coupling is configured for ENFIT compatibility, and features a sloped surface to direct fluid into the syringe, along with a sealing mechanism and flanges for secure engagement with the bottle, ensuring that all fluid can be withdrawn.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a conventional adapter is used for fluid transfer, then the adapter can be easily engaged with the bottle, but residual fluid remains in the bottle (0.50 g to 1.50 g) that cannot be withdrawn
Solution Approach 1:
The patent introduces a sloped surface feature that changes the geometric dimensioning of the adapter interior. This sloped surface creates a fluid pathway that directs remaining fluid toward the withdrawal port, effectively using dimensional geometry to overcome the dead zone problem in conventional cylindrical adapters.
Solution Approach 2:
The adapter incorporates a localized sloped surface feature within its interior geometry. This local geometric modification creates a specific fluid flow path in the critical region near the bottom of the adapter, while the rest of the adapter structure remains unchanged, allowing targeted improvement of fluid withdrawal without redesigning the entire system.
2Quantity of substance
If the male coupling extension height is increased to reach more fluid, then more fluid can be withdrawn, but the syringe coupling position becomes too high above the adapter floor
Solution Approach 1:
Instead of increasing the vertical height of the male coupling extension, the patent uses a sloped surface that extends horizontally toward the fluid source. This dimensional change allows the coupling to reach fluid that would otherwise be inaccessible without increasing the coupling's height above the adapter floor.
Solution Approach 2:
The sloped surface introduces a curved or angled geometry rather than a straight vertical extension. This curved pathway allows the male coupling to access fluid in a more efficient geometric configuration, reducing the need for excessive extension height while maintaining fluid withdrawal capability.
3Productivity
If a sloped surface is added to direct fluid into the syringe, then fluid withdrawal is improved, but the adapter structure becomes more complex
Solution Approach 1:
The sloped surface is implemented as a localized feature within the adapter interior rather than a complete structural redesign. This local modification maintains the simplicity of the overall adapter structure while providing the functional benefit of improved fluid direction and withdrawal efficiency.
Solution Approach 2:
The sloped surface is integrated into the existing adapter body structure, combining the fluid directing function with the structural support function. This merging eliminates the need for separate fluid direction components, maintaining structural simplicity while achieving improved fluid transfer productivity.
