Multi-layer Drain Cover with Segmented Grates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drain covers are ineffective in managing diverse debris types and sizes during heavy rainfall, leading to clogged drains and potential flooding, as they lack a durable and multi-faceted design to filter debris efficiently and remain in place.
Innovation Solution
A multi-layered drain cover apparatus comprising an upper and lower grate piece with differently sized apertures, a filter, and a weighted alignment and support block, allowing water to pass while filtering debris, and secured with magnets for stability and ease of cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-layer drain cover is used, then the device complexity is low, but the ability to filter diverse debris sizes and shapes is insufficient
Solution Approach 1:
The drain cover is divided into multiple grate pieces (first grate piece, second grate piece, third grate piece) with different aperture configurations. Each grate piece targets specific debris sizes and shapes, creating a segmented filtering system that handles diverse debris types more effectively than a single-layer cover.
Solution Approach 2:
The invention transitions from a single-layer to a multi-layer vertical structure. The grate pieces are stacked at different heights above the drain opening, creating a three-dimensional filtering system that intercepts debris at multiple levels, improving adaptability without significantly increasing horizontal complexity.
2Adaptability or versatility
If a multi-layered drain cover with multiple grate pieces is used, then the filtering capability for diverse debris is improved, but the device complexity increases
Solution Approach 1:
Multiple grate pieces with different filtering functions are merged into a single integrated drain cover assembly. The first, second, and third grate pieces work together as a unified system, combining their individual filtering capabilities to handle diverse debris types while maintaining a cohesive structural design.
Solution Approach 2:
The multi-layered drain cover assembly serves multiple functions simultaneously: the first grate piece filters large debris, the second grate piece filters medium debris, and the third grate piece filters small debris. This universal design allows a single device to handle various debris sizes and shapes that would require different separate covers.
3Ease of operation
If the drain cover is made lightweight for easy installation, then the ease of operation is improved, but the stability during heavy rainfall deteriorates
Solution Approach 1:
The alignment and support block serves as a counterweight element within the drain cover assembly. This weighted component provides downward force that anchors the multi-layered grate structure in place, counteracting the upward force of flowing water and preventing the cover from being displaced during heavy rainfall, while the overall assembly remains manageable for installation.
Solution Approach 2:
The grate pieces are pre-positioned at specific heights above the drain opening during manufacturing or assembly. This preliminary positioning ensures proper alignment and spacing before installation, making the installation process simpler and reducing the need for complex adjustments on-site, thereby maintaining ease of operation while ensuring stable performance.

AI summary
A drain cover apparatus includes an upper grate piece comprising a rigid structure with a first plurality of apertures extending through the rigid structure, a lower grate piece comprising a rigid structure with a second plurality of apertures extending through the rigid structure, and an alignment and support block that is configured to support the upper grate piece and align the upper grate piece with the lower grate piece while maintaining an air gap between the upper grate piece and the lower grate piece. The first plurality of apertures are shaped differently than the second plurality of apertures.
