Drain Fitting Ball Joint Socket for Washbasin Space Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drain fittings for washbasins often limit the use of space below the sink due to the placement of odor traps and actuating linkages, requiring additional work and reducing storage capacity in base cabinets.
Innovation Solution
A drain fitting with a ball joint socket and articulated drain pipe bend allows for flexible installation and adjustment, enabling the drain pipe to be positioned on either side of the drain pipe section, and includes a second socket for the actuating rod, allowing for easy connection to the valve body and accommodating various orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional drain fitting with odor trap and actuating linkage is used, then the drain valve can be actuated properly, but the space below the washbasin is significantly limited and base cabinets require additional work
Solution Approach 1:
The patent combines the odor trap and drain valve housing into a single integrated unit that is arranged directly on the underside of the washbasin. This merging eliminates the need for separate odor trap recesses in base cabinets and reduces the overall space required below the washbasin while maintaining proper drain valve actuation functionality.
Solution Approach 2:
The patent repositions the odor trap from a vertical arrangement (requiring recesses in base cabinets) to a horizontal arrangement directly on the underside of the washbasin. This dimensional change allows the odor trap to be integrated into the washbasin structure itself, freeing up space in base cabinets for storage or other purposes.
2Reliability
If a long intermediate pipe is used to connect the drain pipe to the odor trap, then proper drainage connection is achieved, but installation complexity and space requirements increase
Solution Approach 1:
The patent merges the odor trap and drain valve housing into a single integrated component that is positioned directly on the underside of the washbasin. This eliminates the need for long intermediate pipes and multiple separate connections, simplifying the overall pipe arrangement while maintaining reliable drainage connection through the integrated design.
3Ease of manufacture
If the drain pipe section has fixed connection points, then manufacturing is simplified, but adaptability to different installation positions is reduced
Solution Approach 1:
The patent incorporates a ball joint connection between the drain pipe section and the odor trap housing, allowing the drain pipe to be adjusted to different positions and orientations. This dynamic connection maintains ease of manufacture through a standardized ball joint component while providing adaptability to various installation positions and accommodating different spatial configurations.

Function Achieved in This Case
This design enhances space utilization below the washbasin, allows for easy installation, and provides flexibility in accommodating different drain pipe positions, making it suitable for various configurations and improving accessibility for users with disabilities.
Implementation Method 1
the socket provided with the drain pipe bend is designed as a ball joint socket to which the drain pipe bend is articulated
Implementation Method 2
a siphon housing which is arranged directly on the underside of the washbasin

AI summary
The discharge fitting has a discharge valve housing (3), a discharge pipe section (5) and a mounting rod for actuating a valve body (4) which is inserted in the discharge housing. The discharge pipe section has a support for introducing the actuating rod into the valve body. A ball joint socket (5.3) is formed at the discharge pipe section. The ball joint socket runs transverse to a vertical central axis (M), where a flow pipe bend (6) is connected in a fluid tight manner at the ball joint socket which is smaller than the height of the flow pipe section.
