Solution Overview

Problem

Conventional building materials, particularly in deck structures, face issues with moisture-related degradation, rot, and premature failure due to inadequate moisture management and airflow, especially when pressure-treated joists and composite decking are used.

Innovation Solution

A textured substrate with protrusions is placed between building materials to create an airflow water void, allowing moisture to drain away and preventing trapped water, while maintaining structural integrity and aesthetic appeal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional building materials are placed in direct contact, then structural integrity and ease of assembly are improved, but moisture accumulation and rot degradation occur

Engineering Contradiction:

Improvestructural integrityVSAvoidmoisture accumulation

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

A textured substrate is placed between building materials such as joists and decking to act as an intermediary layer. This substrate creates an airflow water void that prevents direct contact between materials, allowing moisture to drain away while maintaining structural integrity and preventing rot degradation.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The substrate incorporates protrusions with specific textures and geometries at localized positions to create airflow channels and water voids. These local structural variations enable moisture management at critical contact points between building materials without compromising overall structural strength.

Inventive Principle:

Principle #3Local quality

2Ease of manufacture

If building materials are placed in direct contact, then ease of installation is improved, but moisture drainage and airflow are reduced

Engineering Contradiction:

Improveease of installationVSAvoidmoisture drainage

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The textured substrate serves as a pre-fabricated intermediary component that simplifies installation by providing built-in airflow channels and drainage paths. Installers simply place the substrate between materials, and the protrusions automatically create the necessary voids for moisture management without complex assembly steps.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The substrate features a porous or textured structure with protrusions that create interconnected airflow channels and water voids. This porous design allows moisture to drain away while maintaining ease of installation, as the drainage functionality is integrated into the substrate structure itself.

Inventive Principle:

Principle #31Porous materials

3Object-affected harmful factors

If protrusions are added to create airflow voids, then moisture management is improved, but device complexity increases

Engineering Contradiction:

Improvemoisture managementVSAvoidsubstrate structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Rather than making the entire substrate complex, protrusions are added only at specific locations where moisture accumulation is most problematic. The textured surface with localized protrusions creates airflow voids exactly where needed at material interfaces, keeping the overall device simple while effectively managing moisture.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The substrate is designed as a thin, flexible membrane with integrated protrusions that can conform to irregular surfaces. This thin-film approach with minimal added complexity provides effective moisture management through the protrusion-created voids without requiring thick or rigid structures.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

A textured barrier substrate includes a substrate having a first side and a second side opposing the first side. One or more protrusions extend from the second side. The first side is configured for securing to a first building structure, such as a joist, and the protrusions are configured to contact and support a second building material, such as flooring.
