Solution Overview

Problem

Existing solutions for insulating floors over crawl spaces are costly due to the need for specific insulation skirts for each type of joist, leading to increased complexity and expense.

Innovation Solution

An assembly comprising insulation panels based on cellular plastic material, supported by shaped metal or plastic pieces that can be easily installed astride shear walls, eliminating the need for multiple thermal break references and simplifying the installation process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If specific skirted infill blocks are used for each type of joist to provide thermal insulation, then thermal insulation performance is improved, but manufacturing cost and device complexity increase

Engineering Contradiction:
Improvethermal lossVSAvoidnumber of distinct references for floor insulation components
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The support piece is designed as a universal component that can be used with different types of joists and partition walls. Instead of creating specific skirted infill blocks for each joist type, a single support piece design serves multiple functions and configurations, reducing the number of distinct references while maintaining thermal insulation effectiveness.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The insulation system is segmented into modular components: standard infill blocks between joists, and separate support pieces with insulation panels for partition walls. This segmentation allows the support piece to be a standalone universal component rather than requiring customized integrated solutions for each joist type.

Inventive Principle:
Principle #1Segmentation

2Loss of energy

If multiple distinct insulation components are used for different areas of the floor, then thermal insulation coverage is improved, but manufacturing cost increases

Engineering Contradiction:
Improvethermal lossVSAvoidmanufacturing cost
Core Design Contradiction:
Loss of energyVSEase of manufacture

Solution Approach 1:

The support piece serves as a universal component that addresses thermal insulation needs across different areas of the floor (partition walls, intermediate load-bearing walls) without requiring multiple distinct products. This universality reduces manufacturing costs by standardizing the component design while maintaining comprehensive thermal coverage.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Loss of energy

If traditional insulation installation methods are used, then thermal insulation is provided, but installation time and complexity increase

Engineering Contradiction:
Improvethermal lossVSAvoidinstallation time
Core Design Contradiction:
Loss of energyVSLoss of time

Solution Approach 1:

The support pieces are pre-formed with the appropriate shape and structure before installation. The folding of metal strips into U-shapes with impalement tabs is done in advance during manufacturing, so that during construction, installers only need to place the support pieces and attach insulation panels, significantly reducing on-site installation time and complexity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The support piece incorporates foldable elements that can be manually folded over the panel after impalement, providing a simple dynamic adjustment mechanism that facilitates quick installation without requiring complex fastening systems or multiple components.

Inventive Principle:
Principle #15Dynamics
