Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drainage channels and floor drains face challenges in achieving both aesthetic and functional design, particularly in creating a slope for efficient water drainage while maintaining stability and ease of installation, especially when placed close to walls.
Innovation Solution
A drainage channel designed with elongated dimensions, formed from a single piece of sheet metal, featuring a gutter connector with legs that slope towards the gutter socket, ensuring efficient water flow and integration with the floor covering, and a floor drain with a flexible design for easy installation near walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a drainage channel is made long (at least 60 cm, often over 80 cm or 100 cm) to drain large floor areas, then the drainage coverage is improved, but the stability and connection rigidity deteriorate
Solution Approach 1:
The drainage channel is divided into multiple individual channel elements that can be connected to each other. Each element has a manageable length that maintains stability, while the segmented structure allows the overall drainage system to cover large floor areas. The connection pieces join these segments while maintaining structural rigidity.
Solution Approach 2:
The connection piece is integrated into the channel element structure, with the connection socket and connection surface forming a nested arrangement. The connection piece fits within the channel element's geometry, creating a compact and stable joint that maintains rigidity without adding excessive horizontal extension.
2Reliability
If the floor drain is given a considerable horizontal extension to be permanently integrated into the supporting flooring and sealed, then the sealing and integration are improved, but the ease of installation near walls deteriorates
Solution Approach 1:
The floor drain system is separated into distinct components: the drainage channel elements that can be installed close to walls, and the floor drain body that provides sealing and integration. This segmentation allows the channel to reach wall-adjacent positions while the floor drain maintains its sealing function without requiring excessive horizontal extension.
Solution Approach 2:
The connection piece acts as an intermediary between the drainage channel and the floor drain. It provides the watertight connection and structural coupling, allowing the channel to be positioned close to walls while the floor drain remains at an optimal distance for sealing and integration into the supporting flooring.
3Device complexity
If the drainage channel is made as a single piece from sheet metal to reduce complexity, then the manufacturing simplicity is improved, but the ability to achieve sufficient stability and connection rigidity worsens
Solution Approach 1:
The connection piece is merged with the channel element to form an integrated component. This merging maintains manufacturing simplicity while the designed connection geometry (socket and surface arrangement) ensures sufficient connection rigidity and stability.
Solution Approach 2:
The sheet metal channel elements have varying thicknesses in different regions - thicker in areas requiring strength and connection rigidity, thinner in areas where flexibility and aesthetics are prioritized. This local variation in quality maintains overall simplicity while achieving necessary structural performance.

Function Achieved in This Case
The solution provides a cost-effective, stable, and aesthetically pleasing drainage system that efficiently directs water to the floor drain while allowing for flexible installation options, including placement close to walls.
Implementation Method 1
water that reaches the drainage channel from the floor surface adjacent to the upper side of the drainage channel is directed in the drainage channel to its channel socket and from there flows into the floor drain
