Surface Drainage Channel Cover with Segmented Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface drainage device covers, such as those with lattice bars or U-shaped profiles, fail to provide adequate stability while maintaining a simple design and high drainage capacity, often leading to structural issues like spreading or buckling.
Innovation Solution
A channel-shaped cover with surface sections connected by a lower connection section and end-side support sections, featuring bridge elements for increased stability and drainage openings, preferably made from sheet metal for easy production and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If lattice bars or U-shaped profiles are used for the cover, then drainage capacity is improved, but structural stability deteriorates due to spreading or buckling
Solution Approach 1:
The cover is divided into multiple surface sections connected by connection sections, with support sections at the ends. This segmentation allows each component to perform its specific function: surface sections for drainage, connection sections for linking, and support sections for structural stability, resolving the contradiction between drainage capacity and structural stability.
Solution Approach 2:
The connection sections are designed to extend downward below the level of the surface sections, creating a lower connection section. This dimensional change provides structural reinforcement without interfering with the drainage function of the upper surface sections, simultaneously achieving both drainage capacity and stability.
2Productivity
If lattice bars are used to provide drainage openings, then drainage capacity is improved, but design simplicity and comfort deteriorate
Solution Approach 1:
The cover combines smooth surface sections for comfort with localized drainage openings in the connection sections. This local differentiation allows the majority of the surface to be smooth and comfortable for barefoot walking, while drainage functionality is concentrated in specific areas where it is needed, resolving the contradiction between comfort and drainage capacity.
3Stability of the object's composition
If U-shaped profiles are connected to prevent spreading, then structural stability is improved, but device complexity increases
Solution Approach 1:
The support sections are integrated as integral parts of the cover structure, formed from the same sheet metal material as the surface and connection sections. This merging eliminates the need for separate support components, achieving structural stability through the unified design while maintaining simplicity and reducing the number of parts.
Solution Approach 2:
The cover utilizes the physical properties of sheet metal material, bending and forming it into the required three-dimensional shape with surface sections, connection sections, and support sections. This parameter change from flat sheet to formed structure provides both stability and drainage functionality without requiring additional components.

AI summary
The cover has two walk-face sections (10, 11) that are connected, with respect to underlying connection portion (12) of drainage openings (13). The marginal support portions (20, 21) configured for supporting the cover in a floor built-collecting portion in drainage channel. The connecting portion is extended parallel to the support sections. The spacer elements are configured to form a defined gap between the support sections and a receiving portion.
