Solution Overview

Problem

Existing insulation materials face challenges in maintaining structural integrity on large diameter installations, especially when flexible materials sag or collapse under weight, leading to poor energy efficiency, noise reduction, and condensation issues due to their lack of rigidity and compressibility.

Innovation Solution

A shaped article made from an expanded and crosslinked elastomeric material with tapered recesses forming a pointed angle, providing structural integrity while remaining flexible and compressible, formed by an interpenetrating network of crosslinked elastomer polymer and resin, which can be easily installed and self-supporting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If flexible elastomeric insulation material is used, then ease of installation and flexibility are improved, but structural integrity and load-bearing capacity deteriorate

Engineering Contradiction:
Improveease of installationVSAvoidstructural integrity
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The patent applies composite materials by combining elastomeric polymer with reinforcing fibers or mesh within the foam structure. This creates a hybrid material that exhibits both the flexibility and ease of installation of elastomeric materials and the structural integrity and load-bearing capacity of composite reinforcement, directly resolving the technical contradiction between softness and strength.

Inventive Principle:
Principle #40Composite materials

2Strength

If rigid insulation material is used, then structural integrity is improved, but ease of installation and ability to close gaps deteriorate

Engineering Contradiction:
Improvestructural integrityVSAvoidease of installation
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The patent applies local quality by creating regions of different stiffness within the insulation material. The elastomeric base provides flexibility for installation and gap-closing, while localized reinforcement zones provide structural integrity. This spatial variation in material properties allows the single material to exhibit both rigid and flexible characteristics as needed.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If flexible insulation material is used on large diameter installations, then ease of installation is improved, but sagging and collapse under weight occur

Engineering Contradiction:
Improveease of installationVSAvoidresistance to sagging
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent applies composite materials with embedded reinforcement structures that provide tensile strength and dimensional stability. The reinforcement network prevents sagging and collapse under the weight of the insulation layer on large diameter installations, while the elastomeric matrix maintains flexibility for ease of installation.

Inventive Principle:
Principle #40Composite materials

4Strength

If additional support strips or belts are applied to flexible insulation, then structural integrity is improved, but device complexity and cost increase

Engineering Contradiction:
Improvestructural integrityVSAvoidcomplexity of support structure
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent applies merging by integrating the reinforcement function directly into the insulation material itself rather than using separate support strips or belts. The reinforcing fibers or mesh are embedded within the elastomeric foam, combining the insulation and structural support functions into a single unified component, thereby reducing device complexity and eliminating additional installation steps.

Inventive Principle:
Principle #5Merging (Combining)
