Inflatable Repair Kit with Bayonet Coupling and Sealing Liquid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing kits for inflating and repairing inflatable articles, such as tires, are bulky, heavy, and require additional work to connect separate components, with the container and dispenser unit needing replacement when the sealing liquid expires, leading to increased costs and complexity.
Innovation Solution
A compact kit with a compressor assembly, a container of sealing liquid housed in an outer casing with a detachable seat, and a two-way valve device that maintains the container as a sealed, independent unit, allowing for easy connection and reducing the need for frequent replacement of the dispenser unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the container is permanently fitted to the dispenser unit, then the connection is stable and sealed, but the container becomes undetachable and must be replaced along with the dispenser unit when the sealing liquid expires
Solution Approach 1:
The system is divided into separable components: the dispenser unit with integrated bayonet connector and the container with matching coupling. This segmentation allows the container to be detached and replaced independently while maintaining a stable sealed connection during use, resolving the contradiction between connection reliability and replaceability.
2Adaptability or versatility
If the container and dispenser unit are separate parts that must be connected prior to use, then the container can be replaced when needed, but additional work is required prior to use
Solution Approach 1:
The container is pre-filled and sealed at the factory with the sealing liquid. The bayonet coupling mechanism is pre-configured on both the dispenser unit and container, allowing for quick connection without additional setup work. This preliminary preparation eliminates the need for complex assembly prior to use while maintaining replaceability.
3Reliability
If a sealed container with a sealing membrane is used, then the container remains sealed until use, but the dispenser unit must still be fitted to the container just prior to use
Solution Approach 1:
The sealing function and the connection function are merged into a single bayonet coupling mechanism. The sealing membrane is integrated with the container opening, and the bayonet connector on the dispenser unit simultaneously breaks the seal and establishes both mechanical connection and fluid pathway. This merging eliminates the need for separate sealing and connection steps.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The kit provides a compact, integrated solution for tire repair and inflation with reduced size and weight, eliminating the need for additional setup and allowing only the container to be replaced when the sealing liquid expires, thus lowering costs and simplifying usage.
Implementation Method 1
the compressor is started to feed the liquid into the tyre
Implementation Method 2
penetrates any holes or slits in the article, and sets on contact with air, thus rapidly sealing the article

AI summary
A kit for inflating and repairing inflatable articles, in particular tires, the kit having a compressor assembly, a container of sealing liquid and connectors for connecting the container to the compressor assembly and to an inflatable article for repair or inflation; the compressor assembly being housed in an outer casing defining a seat for the container of sealing liquid. The container is housed removably in the seat and functionally connected to the compressor assembly so as to form a compact unit ready for use.
