Solution Overview

Problem

The existing methods for installing composite insulation panels in buildings are complex and time-consuming, requiring on-site application of seals which can cause adjacent panels to become permanently fixed, complicating disassembly and recycling.

Innovation Solution

Manufactured composite insulation panels with pre-applied closed cell foam seals, formed from a polyol and isocyanate component with additives, that fix to the inner faces of overlap parts for releasable assembly without permanent bonding, simplifying installation and ensuring correct sealing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If adhesive tape or sealant is applied on-site to bond panels together, then the panels are sealed and bonded, but the installation process becomes complex and time-consuming, and panels become permanently fixed

Engineering Contradiction:
Improvesealing effectivenessVSAvoidinstallation speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The sealant is pre-applied to the overlap portions of the panels during manufacturing, so that when panels are assembled on-site, the sealing function is already in place. This eliminates the need for workers to apply sealant on-site, significantly reducing installation time and complexity while ensuring consistent sealing quality.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If adhesive tape or sealant is applied on-site to bond panels together, then the panels are sealed, but the process requires complex on-site operations and reduces ease of installation

Engineering Contradiction:
Improvesealing effectivenessVSAvoidease of installation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The sealant is pre-applied to the overlap portions of the panels during manufacturing, so that when panels are assembled on-site, the sealing function is already in place. This eliminates the need for workers to apply sealant on-site, significantly reducing installation time and complexity while ensuring consistent sealing quality.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If panels are bonded together using adhesive tape or sealant on-site, then the panels are fixed together, but disassembly and recycling become difficult

Engineering Contradiction:
Improvebonding strengthVSAvoiddisassembly ease
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The patent specifies using a two-component polyol and isocyanate foam sealant that cures to provide strong bonding. The chemical composition and curing parameters are controlled to achieve optimal balance between bonding strength and potential reversibility, allowing panels to be securely fixed during service but potentially separated for recycling at end-of-life.

Inventive Principle:
Principle #35Parameter changes

4Reliability

If sealant is applied on-site, then panels are sealed and bonded, but the installation process requires more time and reduces productivity

Engineering Contradiction:
Improvepanel bondingVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The sealant is pre-applied to the overlap portions of the panels during manufacturing, so that when panels are assembled on-site, the sealing function is already in place. This eliminates the need for workers to apply sealant on-site, significantly reducing installation time and complexity while ensuring consistent sealing quality.

Inventive Principle:

AI summary

A manufactured composite insulating panel (1) comprises an external sheet (4) having an outer face and an inner face, an internal sheet (2) having an outer face and an inner face, and an insulating body (5) between the inner face of the external sheet (4) and the inner face of the internal sheet (2). The external sheet (4) has a portion that extends beyond the internal sheet (2) and the insulating body (5) to define an overlap part for overlapping with part of an adjacent panel, on assembly and a seal (21, 22) is applied to the inner face of the overlap part of the external sheet (4). The panel has a side overlap part (12) to which a side seal (21) is factory applied. An end seal (22) is also factory applied to an end overlap part (16) of the panel.
