Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing drainage materials for staircases require laborious and critical cutting and alignment processes to ensure proper drainage channel alignment, making the installation process time-consuming and prone to errors.
Innovation Solution
A drainage material with interconnected depressions and carrier sections, covered with a liquid-permeable sheet, where the carrier material is dimensioned to fit the stair edges, allowing for simultaneous installation of tread and butt surfaces with aligned drainage channels, and optionally using perforated plastic films or foamed plastic with integrated channels and a fleece or mesh cover for efficient water drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sheet or plate-shaped drainage materials are used for staircases, then drainage function is provided, but laborious cutting and alignment processes are required to ensure proper drainage channel alignment
Solution Approach 1:
The drainage material is divided into multiple pre-cut carrier material sections, each with integrated drainage channels. These sections are designed to fit specific stair components (tread, riser, stringer) and can be independently installed, eliminating the need for on-site cutting and alignment of single large sheets.
Solution Approach 2:
The drainage channels in the carrier material sections are pre-formed and pre-aligned during manufacturing. The sections are designed with predetermined dimensions and channel orientations that match the geometric relationships of stair components, so that when installed, the drainage channels are automatically aligned without requiring manual adjustment.
2Manufacturing precision
If drainage materials are cut to size for each step, then proper fit to stair geometry is achieved, but the cutting process becomes complex and error-prone
Solution Approach 1:
The drainage material is segmented into multiple pre-cut sections, each designed to fit a specific stair component (tread, riser, stringer). These sections are manufactured with precise dimensions and shapes that match the geometric requirements of different stair elements, eliminating the need for complex on-site cutting operations.
Solution Approach 2:
The drainage material sections are manufactured with varying geometric parameters (dimensions, shapes, channel orientations) that correspond to different stair components. This allows each section to be optimally fitted to its specific location without requiring complex cutting operations during installation.
3Productivity
If carrier material sections are used with different area sizes for tread and butt surfaces, then one-step coverage is enabled, but the carrier material structure becomes more complex
Solution Approach 1:
The carrier material is divided into multiple sections with different area sizes and shapes, each optimized for a specific stair component (tread, riser, stringer). These segmented sections can be independently installed in one step, achieving rapid coverage while the structural complexity is managed through modular design.
Solution Approach 2:
The carrier material sections are designed as multi-functional components that can be applied to different stair elements (tread, riser, stringer) with varying geometries. Each section maintains the essential drainage function while adapting to its specific application location, enabling one-step coverage across diverse surfaces.

AI summary
The material (10) has a carrier material (12) provided with slots that are connected with one another and applied on a surface of a step (24). The carrier material has two carrier material-sections that are connected with one another. The sections are dimensioned in such a manner that one section in its breadth corresponds to a length of a step edge, and the other section in its breadth corresponds to the length of the step edge and in its height corresponds to perpendicular height of a side step surface (24a) of a stair step that is provided with a slabbed area.
