Solution Overview

Problem

Channel drains disrupt the aesthetic appearance of landscaped surfaces due to their visual contrast with materials like colored concrete, aggregate, tile, or stone, necessitating a solution that blends the drain with the surrounding surface while maintaining drainage functionality.

Innovation Solution

A channel drain design featuring a body with support surfaces and inserts that allow for the incorporation of material matching the fabricated surface, creating a seamless appearance by defining a gap for fluid flow and using connectors and spacers for structural support and installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional grate is used for the channel drain, then drainage functionality is provided, but aesthetic appearance is disrupted due to visual contrast with the fabricated surface

Engineering Contradiction:
Improvedrainage functionalityVSAvoidaesthetic appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The insert is designed to replicate the appearance, color, and texture of the surrounding fabricated surface (colored concrete, aggregate, tile, or stone). By copying the visual characteristics of the surface material, the insert becomes visually indistinguishable from the surrounding area, allowing the drainage function to be maintained while the aesthetic appearance is preserved.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The insert is manufactured in colors and finishes that match the fabricated surface materials. This color matching eliminates the visual contrast between the drain and the surrounding surface, allowing the drain to blend seamlessly into the landscape while maintaining its drainage functionality through the grate structure.

Inventive Principle:
Principle #32Color changes

2Shape

If the channel drain is made to blend with the surface using matching materials, then aesthetic appearance is improved, but device complexity increases due to additional inserts and material incorporation

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidstructure complexity
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The channel drain is divided into modular components: the main body and separate inserts. Each insert is an independent element that can be manufactured separately and then installed into the body. This segmentation allows for simplified manufacturing of individual parts while achieving the complex aesthetic effect of a seamless surface when assembled.

Inventive Principle:
Principle #1Segmentation

3Shape

If inserts are added to match the surface appearance, then aesthetic blending is achieved, but manufacturing complexity increases

Engineering Contradiction:
Improveaesthetic blendingVSAvoidmanufacturing complexity
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

The inserts are pre-manufactured with the desired surface-matching appearance (color, texture, aggregate distribution) before installation. This preliminary preparation allows the complex aesthetic requirements to be met during manufacturing of the inserts themselves, rather than requiring complex field installation procedures or post-installation finishing work.

Inventive Principle:
Principle #10Preliminary action

AI summary

A channel drain for use in a fabricated surface having an exposed appearance. The channel drain includes a first body having a plurality of support surfaces, with each support surface extending from a respective body sidewall in spaced relation to a body lower wall. A plurality of inserts are insertable into the first body. Each insert includes an insert cavity sized and structured to receive a selected material having an appearance substantially identical to the exposed appearance of the fabricated surface. Each insert is supported by certain ones of the plurality of support surfaces when inserted into the first body and is sized and structured to define a gap between the pair of body sidewalls when inserted into the first body, with the gap allowing for fluid to flow therethrough toward the body lower wall.
