Universal Tubing Fitting for Variable Size Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in the medical field is the variability in tubing sizes, which leads to intermittent availability of compatible fittings, causing production shutdowns and increased costs due to the need for multiple fittings for different sizes of tubing.
Innovation Solution
A single fitting design that accommodates multiple tubing sizes by featuring a tubular portion with an internal bore and external surface, allowing coupling with either external or internal surfaces of flexible tubing, using adhesive or mechanical retention methods to secure the tubing in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple fittings are used for different tubing sizes, then compatibility with various tubing sizes is improved, but device complexity and inventory management complexity increase
Solution Approach 1:
The fitting is designed with a universal interface that can accommodate multiple tubing sizes (e.g., 20G, 22G, 24G) through a single standardized connection mechanism, eliminating the need for multiple specialized fittings and simplifying inventory management
2Adaptability or versatility
If multiple fittings for different tubing sizes are maintained in inventory, then compatibility is improved, but manufacturing costs and inventory management costs increase
Solution Approach 1:
By implementing a universal fitting design that works with multiple tubing sizes, the inventory requirement is reduced from multiple specialized fittings to a single standardized fitting type, directly reducing stockkeeping unit (SKU) complexity and associated costs
3Device complexity
If a single fitting design is used for multiple tubing sizes, then inventory management is simplified, but the precision of fit for each specific tubing size may be compromised
Solution Approach 1:
The fitting incorporates localized sealing surfaces and engagement features that are optimized for each specific tubing size interface, ensuring precise fit and reliable sealing for each tubing gauge (20G, 22G, 24G) while maintaining a universal overall design

AI summary
A body is disclosed that includes a tubular portion with an internal bore and an external surface and a first opening wherein the internal bore terminates at the first opening. The body has a second opening and a fluid passage extending through the body from the internal bore to the second opening. The internal bore is configured to couple to an external surface of a first tube and the external surface is configured to couple to an internal surface of a second tube.
