Detachable Carafe Drain Fitting With Automatic Leak Shut-Off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sanitary washstand or sink outlet fittings require an additional container for transporting liquids, as they do not inherently function as liquid transport containers, leading to inconvenience in tasks like filling carafes or transporting water to remote locations.
Innovation Solution
The outlet fitting features a detachable outlet body with a liquid receiving chamber that can be filled from the base body and used as a transport container, equipped with a plug-in connection, locking mechanism, automatic shut-off valve, and turbulence-generating means to facilitate efficient liquid transfer and prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the outlet body is designed as a detachable liquid container, then the functionality for liquid transport is improved, but the device complexity increases
Solution Approach 1:
The outlet body merges multiple functions into a single component: it serves as both the water outlet nozzle and a detachable liquid storage container. The hollow interior of the outlet body forms a liquid receiving chamber that can store water, eliminating the need for separate storage containers while maintaining the outlet function.
Solution Approach 2:
The outlet fitting is divided into detachable components: the base body remains fixed while the outlet body can be removed and reattached. This segmentation allows the outlet body to function independently as a portable liquid container while being part of the fixed outlet fitting system when attached.
2Ease of operation
If the outlet body is detachable for removal, then the ease of operation is improved, but the reliability of fluid connection deteriorates
Solution Approach 1:
The outlet body incorporates an automatic shut-off valve that self-activates when the outlet body is detached from the base body. The valve mechanism is triggered by the removal action itself, automatically closing the fluid passage without requiring manual intervention, thus maintaining reliability during the detachment operation.
Solution Approach 2:
The shut-off valve is positioned and configured to automatically close before any potential leakage can occur during detachment. The valve mechanism is designed to seal the fluid passage in advance of the separation between outlet body and base body, preventing fluid loss during the transition state.
3Reliability
If a shut-off valve is added to prevent leakage, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The shut-off valve is integrated into the existing outlet body structure rather than being added as a separate external component. The valve mechanism utilizes the hollow interior space of the outlet body and works in conjunction with the detachable connection interface, merging the sealing function with the existing structural elements.
Solution Approach 2:
The shut-off valve operates automatically based on the attachment/detachment state of the outlet body itself. The mechanical movement of attaching or removing the outlet body directly actuates the valve mechanism, eliminating the need for separate control systems or additional actuators.
4Quantity of substance
If the outlet body forms a liquid container, then the quantity of substance stored is improved, but the volume of the outlet fitting increases
Solution Approach 1:
The liquid storage chamber is formed within the existing outlet body structure, utilizing the hollow interior space that would otherwise be empty. This merges the storage function with the outlet nozzle structure, adding liquid container capacity without requiring additional external volume beyond what is already occupied by the outlet body.
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
This design eliminates the need for an additional container, allowing the outlet body to be used as a self-contained liquid transport vessel, ensuring efficient liquid supply and preventing accidental leakage or overflow during transport.
Implementation Method 1
an automatic outflow blocking device that blocks the inflow channel from liquid flowing out of the liquid holding chamber when the outlet body is removed from the base body
Implementation Method 2
through which liquid is introduced into the liquid receiving chamber, forming a centrifugal turbulent flow

AI summary
The fitting has a base body (1) including a terminal for attaching to a liquid supply. A drain body (3) is detachably connected with the base body by a plug connection and a detachable connection (2). The drain body is designed as a liquid container, which is detachable from the base body. The plug connection includes a recess and/or retainer and a connection region at a lower side of the drain body, and at an upper side of the base body. A detent ring and a detent groove detachably lock the plug connection. Air suction ducts are discharged in a supply channel.
