Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drainage systems for building foundations lack a corrugated design, internal membrane, multiple-sided perforations, and modular self-coupling capabilities, which affect structural strength and rigidity.
Innovation Solution
A corrugated foundation drain composed of modular segments with internal webs for stability, multiple-sided perforations, and self-coupling mechanisms using cleats and spacers to prevent bowing and enhance structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional smooth-walled foundation drain forms are used, then manufacturing is simpler, but structural strength and rigidity are insufficient
Solution Approach 1:
The patent applies corrugated (curved/wavy) geometry to the foundation drain form instead of smooth walls. The corrugations create structural rigidity and strength while maintaining the drainage function, directly resolving the contradiction between simplicity and structural performance.
2Ease of operation
If modular self-coupling segments are used, then assembly ease and adaptability improve, but manufacturing complexity increases
Solution Approach 1:
The foundation drain is divided into multiple modular segments that can be assembled together. Each segment has standardized coupling features (cleats and receptacles) that enable easy connection, providing adaptability and ease of assembly while maintaining manufacturing efficiency through repetition of standard components.
Solution Approach 2:
The coupling mechanism uses nested structures where one segment fits into another through receptacles and cleats. This nesting approach provides secure mechanical coupling while keeping the design compact and manufacturable.
3Stability of the object's composition
If internal membranes and webs are added, then longitudinal stability and anti-bowing improve, but manufacturing complexity increases
Solution Approach 1:
The patent incorporates internal membranes (thin flexible walls) within the corrugated segments. These membranes provide longitudinal stability and prevent bowing of the form during concrete pouring, while their thin-film nature keeps manufacturing complexity manageable through integration with the corrugated structure.

AI summary
The present invention relates to a corrugated foundation drain. The drain is comprised of a plurality of segments attached in an end to end fashion. Each segment has a first end and a second end, wherein the second end of one segment can be attached to the first end of an adjacent segment. The drain is corrugated. The drain has sections of corrugations separated by spacers for longitudinal stability. A web is provided within the interior of the drain segments. The web can be vertically centered. In the preferred embodiment, the web can be removed from the first end to provide clearance for receipt of the second end. The second end further can have cleats that interface with the corrugations in the first end.
