Lateral-Exit Drainage Device to Reduce Shower Floor Assembly Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drainage devices for damp rooms, such as showers, require significant floor work and assembly efforts due to their thickness, which can be costly and inconvenient, especially in barrier-free shower installations.
Innovation Solution
A drainage device with a plate-shaped part having a thickness of less than 60 mm, where the drain body does not protrude and lacks an odor trap, featuring lateral connecting means for water exit, and an integrated pump for efficient water removal, reducing installation height and assembly complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing drainage devices are used, then effective water management is achieved, but significant floor work and assembly efforts are required due to thickness
Solution Approach 1:
The drainage device transitions from a vertical protrusion design to a lateral connection design. The connecting means are arranged laterally on the outside of the plate-shaped part, moving the connection interface from the vertical dimension to the horizontal dimension, thereby eliminating the need for floor work and reducing assembly complexity while maintaining drainage functionality.
Solution Approach 2:
The odor trap function is extracted from the traditional vertical drain structure and integrated into the lateral connection system. The drain body does not protrude downwards, and the odor trap is eliminated as a separate component, simplifying the overall structure and reducing assembly requirements while maintaining water management effectiveness.
2Reliability
If traditional drain bodies protruding downwards are used, then odor trap function is achieved, but installation height increases and assembly becomes more complex
Solution Approach 1:
The connection interface is relocated from the vertical dimension to the horizontal dimension. The connecting means are positioned laterally on the outside of the plate-shaped part, allowing waste water to exit laterally rather than vertically. This dimensional shift reduces installation height while maintaining the odor trap function through the lateral connection design.
3Stability of the object's composition
If plate-shaped parts with greater thickness are used, then structural stability is improved, but floor modifications are required and assembly time increases
Solution Approach 1:
The plate-shaped part is designed with an optimized thickness of less than 60 mm, which is sufficient to maintain structural stability for the intended application. This parameter optimization eliminates the need for floor modifications and reduces assembly time, as the thinner profile can be installed without requiring extensive floor work while still providing adequate structural support.

AI summary
The device has a drainage unit (1) with an inlet opening (3) into which waste water can enter. The drainage unit has an outlet opening from which the waste water can leave. A plate-shaped part (2) is a part of a bottom of a moisture-prone area. A connecting unit is provided for connecting the drainage unit with a pump (9). The plate-shaped part has an upper side, lower side and an outer side in an operating position. The connecting unit is designed such that the waste water leaves from the outer side of the plate-shaped part. An independent claim is also included for a moisture-prone area comprising a drainage device.
