Compact Drain Outlet With Siphon Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drains for showers and bathtubs have limited drainage capacity due to small dimensions, leading to water accumulation and inefficient drainage, especially in compact installations like shower trays.
Innovation Solution
The drain design features a siphon channel delimited by the outer side wall and accumulation wall, with an enlarged outlet channel between the siphon and inflow channels, allowing for increased cross-sectional flow and enhanced drainage capacity, along with a removable insert and connecting piece for improved functionality and ease of cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the drain is designed with compact dimensions for shower trays, then the installation space requirement is reduced, but the drainage capacity is limited
Solution Approach 1:
The siphon channel is arranged along the outer side wall of the housing in a longitudinal direction, utilizing the extended side wall area to create a larger cross-sectional flow path. This dimensional reconfiguration allows the compact drain to achieve sufficient drainage capacity by distributing the flow path along the length of the housing rather than requiring a larger radial cross-section.
Solution Approach 2:
The outlet channel is nested between the siphon channel and the inflow channel, with the accumulation wall positioned between them. This nested arrangement optimizes the internal space utilization, allowing multiple functional channels to coexist within the compact housing volume while maintaining adequate flow cross-sections for high drainage capacity.
2Area of moving object
If the siphon channel is arranged along the outer side wall, then the cross section is enlarged, but the housing complexity increases
Solution Approach 1:
The housing internal volume is segmented into distinct functional channels by partition walls: the siphon channel along the outer side wall, the outlet channel nested between, and the inflow channel. This segmentation creates well-defined flow paths with adequate cross-sections while maintaining a relatively simple overall housing structure that can be manufactured as a single piece or modular components.

AI summary
The downpipe has an inflow channel (3) arranged at an upper inlet opening (2), and an outlet opening (5) arranged in an outer sidewall (4) of a housing (1). An accumulation wall (6) is arranged in the housing, in such a manner that a siphon channel (7) and a discharge channel (8) are formed within the housing. The channel (7) is attached to the channel (3), and the channel (8) flows into the opening (5). The channel (7) is limited by the sidewall and the wall (6), and the channel (8) is limited by the wall (6). The channel (8) is arranged between the channel (7) and the channel (3).
