Rotatable Valve Interconnector for Sealing and Recycling Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing valve interconnector system faces issues with poor positional stability of the sealing ring, difficulty in disassembly for recycling, and challenges in ensuring reliable sealing and secure coupling, which can lead to fluid leakage and hinder recycling efficiency.
Innovation Solution
The valve interconnector design allows for a selector mechanism that enables secure attachment and detachment by rotating the base cap, incorporating a selector with ribs and interruptions to ensure irreversible positioning changes, along with a snap coupling and code ring cap for enhanced stability and sealing, and includes a bias spring for reliable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base cap is permanently secured to the neck, then the sealing reliability is improved, but the difficulty of disassembly for recycling increases
Solution Approach 1:
The base cap's attachment state is changed from static (permanently secured) to dynamic (switchable between secured and detached states). The selector mechanism allows the base cap to be toggled between a first state (secured to neck) and a second state (detached from neck), enabling both reliable sealing during use and easy disassembly for recycling after use.
2Reliability
If the sealing ring is compressed axially during coupling, then the sealing performance is improved, but the positional stability of the sealing ring deteriorates
Solution Approach 1:
The solution moves from purely axial compression to a combination of axial compression and radial constraint. The sealing ring is not only compressed axially between the base cap and receiver interconnector but also radially constrained by the sealing ring seat, preventing it from moving out of position while maintaining sealing effectiveness.
3Ease of operation
If the selector mechanism allows rotation of the base cap, then the ease of operation for attachment/detachment is improved, but the device complexity increases
Solution Approach 1:
The selector acts as an intermediary mechanism between the user's rotational input and the base cap's attachment state. It translates simple rotational motion into the secured/detached states through its ribs and interruptions interacting with corresponding features on the neck, providing ease of operation without requiring complex mechanisms.

AI summary
A valve interconnector, suitable for use in combination with a receiver interconnector to couple a first hollow body to a second hollow body, is disclosed. The valve interconnector comprises a neck (7) to be secured to the first hollow body and further comprises a base cap (8) comprising an exterior tube portion (85) covering at least a portion of the external surface (7s) of the neck (7). The exterior tube portion and the neck are secured to each other with ability of relative rotation about a central axis. The valve interconnector is provided with a selector (44, 48) operative between the neck (7) and the exterior tube portion of the base cap (8) and configured for assuming at least a first position and a second position, in the first position the base cap being prevented from being axially released from the neck, in the second position the base cap being enabled to be axially released from the neck.
