Solution Overview

Problem

Existing interlocking concrete pavement systems face challenges with linear drainage systems that are prone to blockage and difficult to install, requiring paver cuts and altering settings, which disrupt paver patterns.

Innovation Solution

A pavement drain with sidewalls forming a perimeter, a central drainage aperture, and circular protrusions for pipe retention, designed to match the size of individual pavers, featuring a drain plate attachment mechanism to prevent debris entry and ensure easy installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If linear drainage systems are installed in interlocking concrete pavement, then drainage function is provided, but installation becomes difficult and paver patterns are disrupted

Engineering Contradiction:

Improvedrainage functionVSAvoidinstallation ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The drainage system is segmented into individual drain units that match the dimensions of single pavers. Each drain is installed independently in the gaps between pavers, eliminating the need to cut multiple pavers or alter their settings. This segmentation allows the drainage function to be integrated without disrupting the paver pattern or complicating installation.

Inventive Principle:

Principle #1Segmentation

2Reliability

If linear drainage systems are installed in interlocking concrete pavement, then drainage function is provided, but paver pattern integrity is compromised

Engineering Contradiction:

Improvedrainage functionVSAvoidpaver pattern integrity

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The drainage system is divided into discrete drain units corresponding to individual paver dimensions. These segmented drains are placed in the natural gaps between pavers, maintaining the regular pattern and symmetry of the pavement design while providing effective drainage functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The drain is designed with specific local dimensions that match the gap geometry between pavers. The drain aperture and positioning are optimized for the local space available between pavers, allowing drainage functionality to be integrated without altering the overall paver pattern or requiring modifications to existing pavers.

Inventive Principle:

Principle #3Local quality

3Reliability

If linear drainage systems are installed in interlocking concrete pavement, then drainage function is provided, but blockage risk increases

Engineering Contradiction:

Improvedrainage functionVSAvoidblockage susceptibility

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The drainage system uses individual, isolated drain units rather than continuous linear channels. This segmentation limits the potential for blockages to confined spaces within each drain unit, preventing widespread clogging and maintaining drainage functionality even if one unit becomes partially obstructed.

Inventive Principle:

Principle #1Segmentation

AI summary

A pavement drain has a perimeter formed by sidewalls, and a drain aperture at the center of the perimeter. A drain surface is provided between form a path from the sidewalls to the drain aperture. A circular protrusion is concentric with the drain aperture and extends downwards from drain surface to engage with a drain pipe.
