Wash stand
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washstand systems are costly to produce and require large installation spaces due to complex shaping and the arrangement of outflow pipes, particularly when made from ceramic materials.
Innovation Solution
A washstand assembly with a water basin and a run-off opening that connects to a separate insert element with a run-off connector, allowing for simplified production by eliminating complex undercuts and optimizing the arrangement of the outflow system, using a plastic insert element with a ceramic washstand, which reduces production costs and compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the washstand is produced with complex chamber shaping and outflow pipe arrangement as in prior art, then the water drainage function is achieved, but the production cost increases significantly and installation space requirement increases
Solution Approach 1:
The washstand is divided into two separate components: a ceramic washstand body and a plastic insert element. The insert element contains the complex outflow channel geometry and is inserted into the washstand body, separating the simple ceramic forming from the complex drainage pathway creation.
Solution Approach 2:
A plastic insert element serves as an intermediary component that provides the complex outflow channel geometry without requiring complex ceramic forming. The insert element acts as a mold or template that defines the drainage pathway while the ceramic body provides structural support.
2Volume of stationary object
If the outflow pipe is arranged in the form of a pipe bend as in prior art, then the water drainage function is achieved, but the installation space required increases
Solution Approach 1:
The outflow channel transitions from traditional horizontal pipe bends to a more compact three-dimensional arrangement within the insert element. The channel directs water downward and rearward in a compact configuration that fits within the washstand structure rather than requiring external pipe bends.
Solution Approach 2:
The outflow channel is nested within the insert element structure, with the drainage pathway integrated into the body of the insert rather than requiring separate pipe components. The run-off connector is positioned to extend through the insert element in a space-efficient manner.
3Ease of manufacture
If complex undercuts are used in washstand shaping as in prior art, then the water drainage function is achieved, but the production outlay increases particularly for ceramic materials
Solution Approach 1:
The complex chamber shaping is segmented from the ceramic washstand body and transferred to the plastic insert element. The ceramic body is formed with simple geometries suitable for standard ceramic forming processes, while the insert element is molded with the precise complex chamber geometry using plastic injection molding.
Solution Approach 2:
The material parameter is changed from ceramic to plastic for the insert element that requires complex shaping. Plastic injection molding allows for complex geometries with undercuts and precise dimensions that would be costly and difficult to achieve with ceramic forming processes.

AI summary
A wash stand assembly that comprises a wash stand having a wash basin and a drain opening through which water to be drained out of the wash basin can be conducted away, the drain opening leading into an inner chamber. The wash stand (2) has a rear wall (6) with which the wash stand (1) comes into contact with a connection structure on the building side when in the installed position. The inner chamber (5) is open in the region of a rear wall (6) of the wash stand (2). An insert element (7) has a drain connection piece (8) for connection to a wastewater pipe on the building side, wherein the insert element (7) is connected to the wash stand (2) such that the inner chamber (5) is sealed watertight and the water can be fed from the drain opening (4) to the drain connection piece (8).
