Self-Closing Hose Screw Coupling With Universal Container Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing flat-tire repair kits are costly due to the need for separate gas pressure source housings for different types of containers, limiting their usage and increasing manufacturing and assembly expenses.
Innovation Solution
The apparatus features at least two different coupling means on the housing that can cooperate with corresponding coupling means on various types of containers, allowing a single gas pressure source to be used with multiple container designs, reducing costs and simplifying handling and connection processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate gas pressure source housings are provided for different types of containers, then each container type can be properly accommodated, but the costs increase and the usage area is limited
Solution Approach 1:
The housing is designed with a universal coupling means that can accommodate multiple types of containers (e.g., sealant containers and compressed air containers) through a single standardized interface. This eliminates the need for separate housings for different container types, reducing device complexity while maintaining adaptability across various container configurations
Solution Approach 2:
The coupling means is designed as a separable, modular component that can be independently attached to different container types. This segmentation allows the same housing to work with various container types by simply changing the coupling attachment rather than the entire housing, thereby reducing the number of complete housings needed
2Adaptability or versatility
If separate gas pressure source housings are provided for different types of containers, then specific container requirements are met, but manufacturing and assembly costs increase
Solution Approach 1:
By designing a single universal housing with a standardized coupling interface that can accommodate multiple container types, the manufacturing process is simplified. Only one housing design needs to be produced at scale, reducing tooling costs, inventory requirements, and assembly complexity compared to manufacturing multiple specialized housings
Solution Approach 2:
The housing design merges the functionality of multiple specialized housings into a single universal unit. This consolidation reduces the total number of parts that need to be manufactured, stored, and assembled, thereby lowering overall manufacturing and assembly costs while maintaining the ability to work with different container types

AI summary
A self-closing screw coupling for hoses, in particular compressed air hoses of tire repair kits, comprising a screw head which can in particular be screwed to a tire valve and can be flowed through by a fluid; a hose connector piece which is rotatably connected to the screw head about a longitudinal hose axis and which can likewise be flowed through by a fluid; a valve which is arranged in a throughflow passage of the screw coupling and has a spring, preferably a spring having a double helix, and a closure part which is biased toward a valve seat by the spring, preferably wherein the closure part has a jacket surface at which a plurality of axially extending ribs are arranged, wherein the spring and the closure part are connected to one another in one piece, and preferably are composed of plastic.
