Drain Cover Assembly with Deformable Tabs for Retaining Wall Voids
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retaining walls with drainage holes and pipes suffer from unsightly voids between round pipes and square holes, which collect debris and attract rodents, compromising aesthetics and functionality.
Innovation Solution
A drain cover assembly with a face plate and flanges that aligns with drainage pipes, allowing water flow while covering voids to prevent debris accumulation, and includes deformable tabs for secure mounting to wall blocks, providing structural support and easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a round drainage pipe is installed in a square drainage hole, then water drainage function is achieved, but unsightly voids are created between the pipe and wall blocks
Solution Approach 1:
A decorative cover plate is introduced as an intermediary element between the round drainage pipe and the square wall block opening. The cover plate fills the void spaces, eliminating the unsightly appearance while preserving the drainage function through its central opening that accommodates the pipe.
Solution Approach 2:
The solution employs a nested structure where the decorative cover plate is positioned within the wall block opening, and the round drainage pipe is nested within the cover plate's central opening. This nested arrangement efficiently fills the square-opening-with-round-pipe configuration, eliminating voids while maintaining the drainage pathway.
2Reliability
If drainage holes and pipes are provided in retaining walls, then water evacuation is facilitated, but debris collection and rodent nesting occur in the void areas
Solution Approach 1:
The decorative cover plate serves as a protective intermediary that covers the void areas around the drainage pipe. This intermediary structure prevents debris from accumulating in the voids and blocks rodent access to the drainage system, while still allowing water to pass through the central opening.
Solution Approach 2:
The solution converts the harmful void spaces into a beneficial decorative feature. The cover plate transforms the previously harmful empty spaces into an aesthetically pleasing element that simultaneously provides protective functions against debris accumulation and rodent intrusion.
3Object-affected harmful factors
If a drain cover assembly is added to cover voids, then debris collection is prevented, but device complexity increases
Solution Approach 1:
The decorative cover plate is designed to perform multiple functions simultaneously: it provides aesthetic coverage, prevents debris accumulation, blocks rodent access, and facilitates installation through integrated mounting features. This multi-functionality reduces the need for separate components, thereby minimizing the increase in device complexity.
Solution Approach 2:
The solution merges the decorative cover function with the mounting mechanism by integrating flanges and fastening features directly into the cover plate structure. This combination eliminates the need for separate mounting brackets or additional fastening components, reducing overall system complexity.

AI summary
A drain cover assembly includes a face plate having at least one hole to allow water to flow from a drainage pipe located in a retaining wall. The face plate includes a first pair of flanges and a second pair of flanges, both of which extend substantially perpendicular to the face plate. The first pair of flanges has a receiving means for receiving a fastener adapted to secure the drain cover assembly to the retaining wall. The second pair of flanges has a plurality of deformable tabs adapted to create an interference fit with the retaining wall. The drain cover assembly may also include a decorative face plate.
