Solution Overview

Problem

Existing perimeter drain systems are limited in their ability to efficiently collect water from multiple sides and lack modular customization options, making them inflexible for various basement and crawl space configurations.

Innovation Solution

A perimeter drain system with a unique shape allowing water entry on multiple sides, modular accessories such as clips for segment connection, corner pieces for navigating corners, and outlets for directing water, along with an inspection port for monitoring, enhancing flexibility and customization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a traditional perimeter drain design is used, then the structure is simple, but water collection capability from multiple sides is limited

Engineering Contradiction:
Improvewater collection capabilityVSAvoiddrain structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The drain body is divided into multiple sides (front, rear, left, right) with each side having independent water collection openings. This segmentation allows water to be collected from multiple directions simultaneously, significantly improving water collection capability while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The drain transitions from a traditional single-side or two-side water collection design to a multi-side (three-dimensional) water collection structure. By adding water collection openings on multiple faces of the drain body, the system captures water from different spatial dimensions, enhancing productivity without proportionally increasing complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If a fixed perimeter drain design is used, then manufacturing is simple, but adaptability to different configurations is poor

Engineering Contradiction:
Improvecustomization for different configurationsVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The perimeter drain system is divided into modular segments that can be independently manufactured and then assembled together. Each segment can be produced using standard manufacturing processes, but the modular nature allows flexible assembly to accommodate different basement and crawl space configurations, enhancing adaptability without significantly increasing manufacturing complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The drain system incorporates adjustable and reconfigurable elements that allow the structure to adapt to different spatial requirements. The modular design enables the system to be dynamically configured for various applications rather than being a fixed, one-size-fits-all solution.

Inventive Principle:
Principle #15Dynamics

3Reliability

If perimeter drain segments are connected without a connection mechanism, then the structure is simple, but assembly stability is poor

Engineering Contradiction:
Improveassembly stabilityVSAvoidconnection mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The connection mechanism integrates the joining function directly into the drain segment interfaces. Connection features such as interlocking elements, gaskets, or fastening mechanisms are built into the segment designs themselves, allowing adjacent segments to be reliably joined together. This merging of the connection function into the primary structure provides assembly stability without requiring separate, complex connection systems.

Inventive Principle:
Principle #5Merging (Combining)
