Drain With Unidirectional Passage Prevents Adhesive Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drains with holes in the side walls for leakage water management allow regular water and soap residues to pass through, damaging the adhesive layer between the finishing layer and the floor, leading to potential tile loosening and leakage issues, particularly in sanitary and industrial applications.
Innovation Solution
A unidirectional passage is implemented to allow only external water to flow into the collecting container, blocking existing water and preventing it from passing under the finishing layer, with secondary drainage activated only when leakage occurs, ensuring a sealed floor and reliable discharge of leakage water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If holes are provided in the side walls of the collecting container for leakage water, then leakage water can enter the collecting container, but water and soap residues pass through and damage the adhesive layer between the finishing layer and the floor
Solution Approach 1:
The drainage function is segmented into two separate systems: a primary drainage system with holes in the collecting container for active leakage, and a secondary drainage system with unidirectional passages in the connecting part for passive leakage. This segmentation allows each system to serve its specific purpose without interfering with the other, preventing soap residue damage to the adhesive layer while maintaining leakage discharge capability.
Solution Approach 2:
The unidirectional passage acts as an intermediary element between the collecting container and the outlet pipe, providing a protected pathway for leakage water. The unidirectional valve mechanism serves as a mediator that allows water to pass in one direction (from the floor into the collecting container) while blocking reverse flow, thus preventing soap residues from damaging the adhesive layer.
2Productivity
If the collecting container is partially or wholly filled with drained water during use, then drainage function is maintained, but water passes between the finishing layer and the floor via holes in the side walls

3Reliability
If a sealing mastic layer is arranged between the finishing layer and the collecting container, then water permeation is prevented, but the seal may crack or fail over time
Solution Approach 1:
The unidirectional passage system provides a pre-prepared backup drainage pathway that activates only when the sealing mastic layer fails. This beforehand cushioning ensures that even if the seal cracks or fails over time, leakage water can still be discharged through the unidirectional passage, preventing water damage to the adhesive layer while maintaining seal integrity during normal operation.

The unidirectional passage acts as an intermediary element between the collecting container and the outlet pipe, providing a protected pathway for leakage water. The unidirectional valve mechanism serves as a mediator that allows water to pass in one direction (from the floor into the collecting container) while blocking reverse flow, thus preventing soap residues from damaging the adhesive layer.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution maintains a watertight finishing layer during normal use, preventing water and soap residue damage, and ensures reliable leakage water discharge only when necessary, thus extending the lifespan of the floor and preventing tile loosening.
Implementation Method 1
By providing a unidirectional passage only water from outside can flow into the collecting container. Water already present in the collecting container is blocked by the unidirectional passage.
