Modular Inground Drain Assembly with Removable Filter Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
French drains often become clogged due to muddy water, roots, and sewage solids, making them difficult to inspect and maintain, leading to foundation issues like uneven settling, cracking, and water damage.
Innovation Solution
A drain assembly comprising a first and second panel with drainage apertures, supported by spacers, a cap, and optionally a filter material, which can be easily inspected and maintained, and may include sensors for monitoring water levels and temperature, allowing for easy installation over existing pipes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional French drains with gravel and perforated pipes are used, then water drainage function is achieved, but the system becomes clogged over time due to muddy water, roots, and sewage solids making inspection and maintenance difficult
Solution Approach 1:
The drain assembly is divided into modular components including removable end caps, panel sections with apertures, and filter material sections. This segmentation allows individual components to be easily removed for inspection and cleaning without disturbing the entire drainage system, directly addressing the maintenance difficulty of traditional French drains.
Solution Approach 2:
A removable filter material is introduced as an intermediary component between the water source and the drainage system. This filter captures muddy water, roots, and sewage solids before they can clog the drainage apertures, while the removable end caps provide access to clean or replace the filter material without extensive excavation.
2Productivity
If gravel is used to provide air space for water passage in French drains, then water flow is enabled, but the gravel becomes clogged and requires digging up for cleaning
Solution Approach 1:
The traditional gravel medium is replaced with a structured panel system featuring apertures and a removable filter. This extraction of the gravel component eliminates the clogging issue entirely while maintaining water flow through the engineered aperture structure, and the removable ends provide access to clean the filter without digging up the entire system.
Solution Approach 2:
The panel structure with apertures serves as a controlled porous medium that allows water passage while preventing clog accumulation. The apertures are designed to maintain water flow efficiency without the drawbacks of gravel, and the removable filter material can be easily cleaned or replaced through the accessible end caps.
3Productivity
If pipes are used to carry water away in French drains, then water transport is achieved, but pipes collapse, fill with roots and sediment, and become clogged within one or two years
Solution Approach 1:
The system transitions from a static pipe structure to a dynamic modular panel assembly with removable ends. This allows the system to be easily accessed, inspected, and maintained throughout its service life, potentially extending the operational duration by enabling regular cleaning and component replacement without full system replacement.
Solution Approach 2:
The removable filter material is installed in advance to prevent roots, sediment, and debris from entering the drainage system. The removable end caps are designed beforehand to provide access points for maintenance, allowing preliminary prevention of clogging issues that typically limit pipe service life.

AI summary
A drain assembly capable of being placed inground includes a first panel and a second panel spaced-apart from the first panel, a plurality of supports extending between the first panel and the second panel, a bottom or pipe extending between a bottom portion of the first panel and the second panel, and a cap extending between a top portion of the first panel and the second panel. The first panel may define a plurality of drainage apertures. A related method is also provided.
