Solution Overview

Problem

Existing insulation systems for complex pipe assemblies, such as mechanical couplings and fittings, fail to provide an effective vapor barrier, leading to heat loss and potential corrosion, especially at joints where pipe elements are connected.

Innovation Solution

A cover system comprising interlocking cover portions with tongue-and-groove arrangements and fluid communication canals, combined with a foam insulation layer and sealant, ensures a continuous vapor barrier and efficient insulation across non-standardized pipe assemblies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If insulation is provided for straight pipe runs using standardized pipe, then insulation installation is straightforward and efficient, but insulation for complex pipe assemblies such as mechanical couplings, valves, and fittings becomes difficult and ineffective

Engineering Contradiction:
Improveinsulation installation easeVSAvoidinsulation adaptability to complex assemblies
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The insulation cover is divided into multiple separate portions (first cover portion, second cover portion, etc.) that can be independently installed on different sections of complex pipe assemblies. Each cover portion can be customized to fit specific geometries while maintaining standardized connection interfaces through tongue-and-groove arrangements, allowing straightforward installation on straight sections while adapting to complex configurations through modular assembly.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If traditional insulation methods are used for pipe assemblies, then installation may be simple, but the vapor barrier function is compromised at joints where pipe elements are connected

Engineering Contradiction:
Improveinstallation simplicityVSAvoidvapor barrier integrity
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The tongue-and-groove connection arrangement with integrated seals ensures continuous vapor barrier protection across joint regions. The groove in one cover portion receives the tongue from another cover portion, creating an interlocking joint that maintains the vapor barrier's continuous protective function throughout the entire insulation system, preventing moisture ingress at connection points between insulation sections.

Inventive Principle:
Principle #20Continuity of useful action

3Area of stationary object

If cover portions are joined together to surround pipe assemblies, then complete insulation coverage is achieved, but gaps or breaches may occur at the seams between cover portions

Engineering Contradiction:
Improveinsulation coverage areaVSAvoidseam integrity
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

Seals act as intermediary elements positioned within the groove regions of cover portions to ensure tight sealing at the seams where cover portions join. These seals fill and seal the groove spaces, preventing any potential gaps or breaches at the interfaces between adjacent insulation sections, thereby maintaining the integrity of the complete vapor barrier system across the entire covered area.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An insulating cover for assemblies including pipe elements, pipe couplings, elbows, Tees and valves also acts as a vapor barrier. Cover portions are joined along a seam which provides for a continuous seal between both the cover portions and the pipe elements which extend through channels defined in the cover. The seam includes a furrow into which sealant is forced when the cover portions are joined around the assembly. The furrow is defined by an asymmetric tongue and groove joint. Canals in the channels, in communication with the grooves, also receive the sealant to provide the continuous seal.
