Solution Overview

Problem

Current industrial insulation lacks a secure and efficient method for bonding protective jacketing, leading to slow installation times, gaps between insulation and jacketing, and increased risk of corrosion due to water infiltration.

Innovation Solution

A composite insulation with pre-applied V-grooves and adhesive coating allows for uniform bonding of a flexible protective jacketing, enabling a single installation step and reducing shipping costs, while the adhesive on the grooves retains the shape of the insulation for easy application around pipes or equipment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If protective jacketing is fastened or banded to industrial insulation, then the insulation can be protected, but installation time increases and gaps remain between insulation and jacketing

Engineering Contradiction:
Improveprotective protectionVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The adhesive coating is pre-applied to the insulation surface before installation, and the protective jacketing is pre-formed with bonding surfaces. This preliminary preparation eliminates the need for现场 bonding operations, significantly reducing installation time while ensuring gap-free contact between insulation and jacketing.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent combines the insulation and protective jacketing into a single integrated unit through pre-applied adhesive bonding. This merging of components eliminates the need for separate fastening operations and ensures continuous contact, preventing gaps that would allow water or vapor infiltration.

Inventive Principle:
Principle #5Merging (Combining)

2Object-affected harmful factors

If protective jacketing is fastened or banded to insulation, then protection is provided, but gaps remain that allow water infiltration and corrosion

Engineering Contradiction:
Improvewater infiltrationVSAvoidbonding method
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent replaces mechanical fastening systems (bands, clips, or other mechanical attachments) with a chemical bonding system using pre-applied adhesive coatings. This substitution creates a continuous, gap-free bond between insulation and protective jacketing, eliminating pathways for water infiltration while simplifying the overall system.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention changes the bonding parameter from mechanical attachment to chemical adhesion. The pre-applied adhesive coating creates molecular-level bonding between surfaces, ensuring complete contact and eliminating gaps that would exist with mechanical fastening methods.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If insulation is installed first then protective jacketing is installed separately, then installation flexibility is maintained, but installation time and labor costs increase

Engineering Contradiction:
Improveinstallation flexibilityVSAvoidinstallation speed
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent merges the insulation and protective jacketing into a pre-assembled unit with adhesive bonding already applied. This allows the combined component to be installed as a single unit, maintaining flexibility in installation locations while dramatically increasing installation speed and reducing labor requirements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The adhesive bonding is performed in advance during manufacturing rather than during field installation. This preliminary action transfers the bonding operation from the installation phase to the manufacturing phase, allowing faster field installation while ensuring proper bonding is achieved under controlled conditions.

Inventive Principle:
Principle #10Preliminary action

AI summary

A V-grooved composite insulation is provided with an adhesive coating and a protective jacketing material bonded to the adhesive. The protective jacketing material extends beyond the perimeter of the grooved insulation board and comprises at least one intact release layer at a location in which the protective jacketing is clear of contact with the bottom surface of the insulation member and a pressure sensitive adhesive between the portion of the protective jacketing material and the at least one release layer. The method also comprises preshaping the grooved insulation board around a pipe by bending the grooved insulation board, removing the release layer of the protective jacketing material, thereby exposing the pressure sensitive adhesive and securing the pressure sensitive adhesive to the protective jacketing to thereby surround the pipe in a vapor free manner. Grooved insulation boards with protective jacketing so constructed are also provided.
