Washbasin Drain Element With Segmented Overflow And Drain Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washbasin systems with integrated drains face challenges in manufacturing complexity and large installation space requirements, particularly due to the arrangement of the drain pipe, and overflow elements are difficult to access when installed.
Innovation Solution
A washbasin arrangement featuring a separate overflow and drain channel system with a check valve, where the overflow channel is accessible via an overflow inlet opening and the drain channel via a drain opening, allowing for independent operation and easy maintenance, with the drain element located within a cavity to minimize space and prevent blockages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drain pipe is arranged in the form of a pipe bend to connect the washbasin to the drain, then the washbasin can be connected to the drain pipe, but the installation space required becomes comparatively large
Solution Approach 1:
The drain element is divided into separate functional channels: a drain channel for normal drainage and an overflow channel for excess water. This segmentation allows each channel to be optimized independently, with the overflow channel providing a alternative drainage path that reduces the need for complex pipe bends, thereby minimizing installation space while maintaining reliable drain connection.
2Reliability
If the overflow element is arranged behind a partition wall to connect to the rear of the washbasin, then the overflow function is provided, but the overflow element becomes very difficult to access when installed
Solution Approach 1:
The overflow channel and its inlet opening are extracted from the traditional hidden position behind partition walls and repositioned to be accessible from the front or side of the washbasin. This allows the overflow element to perform its safety function while remaining easily accessible for maintenance and cleaning, eliminating the accessibility problem without compromising the overflow function.
3Ease of manufacture
If the drain opening and overflow inlet are arranged close together to simplify the structure, then the manufacturing is easier, but blockages in the drain channel can prevent water discharge
Solution Approach 1:
The drain element incorporates a dual-channel system with separate drain and overflow channels that merge at a confluence point. This segmentation ensures that even if one channel becomes blocked, the other remains functional, providing reliable drainage safety while maintaining relatively simple manufacturing through integrated molding of the two channels.

AI summary
A washbasin arrangement (1) comprises a washbasin (2) with a water basin (3), a cavity (4) and a drain passage (5) extending from the water basin (3) into the cavity (4), and a drain element (6) arranged at least partially in the cavity (4) for conveying water away from the drain passage (5) and for supplying the water to a drain pipe, wherein the drain element (6) has an overflow channel (10) with an overflow edge (11) and a drain channel (14) with a shut-off valve (13), and wherein, viewed from the water basin (3), the overflow channel (10) is accessible via an overflow inlet opening (9) and the drain channel (14) is accessible via a drain opening (12), wherein the overflow inlet opening (9) and the drain opening (12) are arranged side by side and offset from each other.
