Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing basement water drainage systems are inefficient in directing and channeling water seepage from foundation walls to drainage conduits, often resulting in residual dampness due to inadequate water flow and contact issues with the foundation surfaces.
Innovation Solution
An L-shaped device comprising a vertical wall panel with elongated, square wave form channels and a horizontally disposed base member, featuring a 45-degree lip to direct water behind the panel and through U-shaped formations to a water-collecting means, enhancing water flow and structural integrity with parallel, perpendicular channels for effective drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing basement water drainage systems are used, then water drainage function is provided, but water flow rate and contact with foundation surfaces are inadequate resulting in residual dampness
Solution Approach 1:
The drainage device is segmented into multiple functional components: a vertical wall panel with channels for directing water down the foundation wall, a horizontal base member with channels for collecting water at the footing level, and multiple U-shaped formations that create parallel drainage pathways. This segmentation allows water to be efficiently channeled through dedicated pathways, increasing overall water flow rate and preventing residual dampness by ensuring complete water evacuation.
Solution Approach 2:
The device transitions from two-dimensional surface contact to three-dimensional channel formation by creating U-shaped formations that extend vertically and horizontally. These three-dimensional channels provide multiple flow paths and increase the effective drainage capacity, allowing water to move more efficiently from the foundation wall through the footing level to the drainage conduit, thereby eliminating residual dampness.
2Ease of operation
If L-shaped device with channels is positioned against foundation wall, then water direction is improved, but structural integrity and water flow enhancement need improvement
Solution Approach 1:
The drainage device is constructed as a composite structure integrating the vertical wall panel and horizontal base member into a unified L-shaped configuration. This composite design provides both structural integrity and effective water direction, as the integrated structure prevents misalignment and ensures that water channeled down the vertical panel is efficiently transferred to the horizontal base member and directed to the drainage conduit.
Solution Approach 2:
The device incorporates curved transitions and rounded channel formations, particularly in the U-shaped formations that connect the vertical and horizontal components. These curved elements facilitate smooth water flow transitions, reducing turbulence and improving water direction efficiency, while also distributing structural stresses more evenly to maintain integrity.
3Productivity
If multiple channels are formed in drainage device, then water channeling is improved, but device complexity increases
Solution Approach 1:
The multiple channels are segmented into distinct functional zones: vertical channels in the wall panel for downward water movement, horizontal channels in the base member for water collection and lateral transport, and U-shaped formations that create parallel drainage pathways. This segmentation allows each channel to perform its specific function efficiently while the modular design keeps manufacturing and installation manageable despite the multiple channels.
Solution Approach 2:
The L-shaped device structure serves multiple functions simultaneously: the vertical wall panel acts as both a structural support and a water channeling surface, the horizontal base member provides both structural stability and water collection capability, and the U-shaped formations create multiple parallel drainage pathways. This multi-functionality reduces the need for additional separate components, thereby managing device complexity while improving water channeling efficiency.

Function Achieved in This Case
The device effectively directs and collects water seepage, increasing its flow rate and volume, reducing residual dampness by ensuring water flows into drainage conduits or gravel, thus improving basement water management.
Implementation Method 1
a lip at the top of the vertical wall panel extending therefrom at a 45-degree angle away from the foundation wall to catch any water that drips from the foundation wall to cause it to pass behind the vertical wall panel and under the horizontally disposed base member
Implementation Method 2
The vertical wall panel has elongated channels of square wave form cross-section adapted to be positioned against the inside foundation wall
