Solution Overview

Problem

Existing insulation housing technologies face challenges in reducing production, storage, and transport costs, and environmental impact due to complex component structures and irreversible material bonding, which hinder efficient recycling and create heat bridges, reducing insulation efficiency.

Innovation Solution

A double-walled insulation housing is configured as a planar surface element with notched transition regions, allowing for efficient storage and transport, and featuring a vacuum-tight fill material like compacted glass fibers for supported vacuum insulation, with stainless steel walls and a thinner transition membrane for improved heat insulation and reduced material usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the insulation housing is produced as a complete three-dimensional structure, then the insulation performance is ensured, but the storage and transport space requirements increase significantly

Engineering Contradiction:
Improveinsulation performanceVSAvoidstorage and transport volume
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The insulation housing is divided into multiple planar panel elements that can be flat-packed for storage and transport, then assembled into a three-dimensional structure during installation or use. This segmentation allows the housing to occupy minimal space during logistics while forming the complete insulated enclosure when needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The planar panel elements are designed to nest within each other or stack in a compact configuration during storage and transport, similar to nested dolls. This nesting arrangement minimizes the volume required for logistics while allowing easy expansion to the full housing structure when deployed.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Stability of the object's composition

If traditional foam insulation is used to fill interstices, then the insulation housing is structurally stable, but material recycling becomes impossible and environmental impact increases

Engineering Contradiction:
Improvestructural stabilityVSAvoidenvironmental impact and recyclability
Core Design Contradiction:
Stability of the object's compositionVSObject-generated harmful factors

Solution Approach 1:

The design enables disassembly of the insulation housing into its component panels and materials, allowing for recovery and recycling of metals, plastics, and other materials at the end of the product lifecycle. This replaces the traditional approach where foam insulation permanently bonded components, making recovery impossible.

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The insulation housing employs composite material construction with distinct layers and components that can be separated for recycling. This includes using materials like vacuum insulation panels combined with metal or plastic housings, where each material type can be recovered and reused in its appropriate recycling stream.

Inventive Principle:
Principle #40Composite materials

3Loss of energy

If vacuum insulation panels with metallic reinforcements are used, then the insulation efficiency is improved, but heat bridges are formed at join regions reducing overall insulation performance

Engineering Contradiction:
Improveheat loss through insulationVSAvoidinsulation continuity at joints
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The design addresses the specific problem at joint regions by using localized insulation solutions at connection points. This may include adding supplementary insulation layers, using insulation-compatible fastening systems, or designing joints that minimize thermal bridging while maintaining the vacuum insulation effectiveness in the panel centers.

Inventive Principle:
Principle #3Local quality

4Loss of energy

If multiple different components and materials are used to achieve high insulation efficiency, then the insulation performance is improved, but production costs and device complexity increase

Engineering Contradiction:
Improveheat loss reductionVSAvoidnumber of components and materials
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The insulation housing design uses standardized panel elements and connection systems that serve multiple functions. The same basic panel structure, insulation material, and joining mechanism are used throughout the housing, eliminating the need for numerous specialized components. This multi-functionality maintains high insulation efficiency while simplifying production and reducing material variety.

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