Solution Overview

Problem

Conventional tubular claddings for thermal insulation of pipes are not deformable in a radial direction, requiring separate claddings for different pipe diameters, leading to storage and transport inefficiencies, as they cannot be folded or compressed for convenient storage or wrapping around supports.

Innovation Solution

A tubular insulating cladding comprising an elastically deformable braided tubular element, an aerogel insulating layer, and a PVC external containment sheath, allowing adaptation to various pipe diameters and enabling compression for storage, with the aerogel layer retained between the tubular element and sheath to ensure effective thermal insulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional tubular claddings are used for thermal insulation, then thermal insulation function is provided, but the claddings cannot be deformed in radial direction requiring separate claddings for different pipe diameters

Engineering Contradiction:
Improveadaptability to different pipe diametersVSAvoidnumber of different cladding types
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cladding incorporates an elastically deformable tubular element that can dynamically adjust its inner diameter to accommodate pipes of different sizes. This dynamic adaptability eliminates the need for multiple fixed-size cladding types, directly resolving the contradiction between versatility and device complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the physical parameter of the tubular element from rigid to elastically deformable, allowing it to change its inner diameter parameter according to the pipe size. This parameter change enables a single cladding design to serve multiple pipe diameters, reducing the number of cladding types needed.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If conventional tubular claddings with fixed diameter are used, then structural stability is maintained, but storage volume and transport volume increase significantly

Engineering Contradiction:
Improvestructural stabilityVSAvoidstorage volume
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The elastically deformable tubular element can be compressed radially during storage and transport, then expands to its original diameter when installed. This dynamic property allows the cladding to occupy minimal storage space while maintaining full structural stability during use, resolving the contradiction between reliability and storage volume.

Inventive Principle:
Principle #15Dynamics

3Loss of energy

If conventional tubular claddings are used, then thermal insulation is provided, but they cannot be folded or compressed for convenient storage

Engineering Contradiction:
Improvethermal insulation efficiencyVSAvoidconvenience of storage and handling
Core Design Contradiction:
Loss of energyVSEase of operation

Solution Approach 1:

The cladding uses a flexible elastically deformable tubular element that can be folded and compressed like a flexible shell, yet maintains its insulating function. This flexibility dramatically improves ease of operation for storage and handling while preserving thermal insulation efficiency through the aerogel material.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The tubular element can change its physical state between compressed/folded for storage and expanded for installation, while the aerogel insulating layer maintains its thermal properties throughout. This parameter change capability resolves the contradiction between insulation efficiency and operational convenience.

Inventive Principle:
Principle #35Parameter changes

4Adaptability or versatility

If multiple series of tubular claddings are stored for different pipe diameters, then complete coverage of pipe sizes is achieved, but storage space requirements increase considerably

Engineering Contradiction:
Improvecoverage of pipe diameter rangeVSAvoidstorage space
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The elastically deformable tubular element provides universal adaptability to accommodate multiple pipe diameters within a single cladding unit. This multi-functionality eliminates the need to store multiple specialized cladding series, dramatically reducing storage space requirements while maintaining complete coverage of the pipe diameter range.

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