Floor Drain Integral Mounting Flange Secure Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current floor drains face challenges in achieving a secure and easy connection to building membranes, particularly in modernizing or rebuilding multi-storey buildings, and require additional anchor means and fittings, making installation tedious and difficult, especially in cast floors and low-height installations.
Innovation Solution
The floor drain features an integral mounting flange with outwardly bent anchor means for secure embedding into cast floors and earth rods for ground anchoring, along with a displaceable inner bowl for height and angle adjustment, and a water trap design to prevent backflow and odor, using stainless steel construction with minimal welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate anchor means are used to secure the floor drain in cast floors, then secure anchoring is achieved, but device complexity and installation time increase
Solution Approach 1:
The mounting flange is made integral with the drain bowl and includes integrated anchor means formed at the outer delimiting edge of the rim area. These anchor means are bent outwards from the plane of the mounting flange and adapted for fixation by embedding into a cast floor, eliminating the need for separate anchor means while providing secure anchoring.
2Adaptability or versatility
If multiple fittings and connecting pieces are used to adapt to different installation situations, then adaptability is improved, but device complexity and installation time increase
Solution Approach 1:
The mounting flange is designed with integrated anchor means that can be embedded into cast floors, and the drain bowl includes a water trap and various connection configurations. This multi-functional design allows the same floor drain unit to be adapted to different installation situations without requiring additional fittings or connecting pieces.
3Length of stationary object
If the floor drain is designed with low installation height, then space utilization is improved, but achieving sufficient slope to sewage system becomes difficult
Solution Approach 1:
The drain bowl features an inclining bottom over a sub-distance, creating a built-in slope that compensates for the low installation height. This dimensional adjustment in the bottom geometry allows sufficient slope to be achieved toward the sewage system connection even when the overall installation height is minimized.

AI summary
A floor drain (2) with a drain bowl (4) with a preferably cylindric outer side (6) and a lower central drain connection (8) which is adapted for connecting to either a straight drain pipe or to an angular drain pipe (12). The drain bowl includes a grate (18) forming a detachable lid and a mounting flange (36) externally of the outer side (6) of the drain bowl (4). The mounting flange (36) is made integral with the drain bowl and is formed by a rim area (38) at the upper edge (40) of the drain bowl. At the outer delimiting edge (44) of the rim area, integrated anchor means (46) are formed, adapted to be bent outwards from the mounting flange plane, and the mounting flange (36) also includes an integrated mounting means (50) for earth rods. In a simple way is hereby achieved a floor drain with a drain bowl (4) with integrated associated mounting flange which may easily be permanently mounted in a floor and which at the same time can be adapted to the height of an existing as well as of a newly established building membrane.
