Solution Overview

Problem

Current vacuum insulation solutions for temperature-controlled goods are expensive, bulky, and difficult to dispose of, making them unsuitable for small or cheap items, and lack efficient production and recycling methods.

Innovation Solution

A vacuum insulation element comprising a core made of structured cardboard or plastic, evacuated within a flexible film envelope, which provides dimensional stability without the need for porous filling materials, allowing for easy assembly and disposal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If conventional expanded polystyrene boxes are used for thermal insulation, then insulation effect is achieved, but the boxes become expensive and bulky

Engineering Contradiction:
Improvethermal insulation effectVSAvoidbox bulkiness
Core Design Contradiction:
TemperatureVSVolume of moving object

Solution Approach 1:

The patent uses a flexible foil covering (metalized or non-metalized) as a thin film shell to enclose the evacuated core, replacing bulky expanded polystyrene with a lightweight flexible membrane that maintains structural integrity while providing thermal insulation in the vacuum state

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent creates a vacuum environment (inert atmosphere without gas molecules) within the foil covering, eliminating convection and conduction heat transfer mechanisms, thereby achieving superior thermal insulation with minimal material thickness compared to conventional polystyrene

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)

2Temperature

If vacuum insulation elements with porous material are used, then insulation is improved, but manufacturing cost and disposal complexity increase

Engineering Contradiction:
Improvethermal insulationVSAvoidmanufacturing cost and disposal
Core Design Contradiction:
TemperatureVSEase of manufacture

Solution Approach 1:

The patent removes the porous filling material from the vacuum insulation structure, using only the evacuated space between the foil covering and the core structure, thereby simplifying manufacturing and disposal while maintaining insulation performance

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent divides the insulation structure into separate functional components: the foil covering provides the vacuum seal, the core structure provides dimensional stability, and the evacuated space provides thermal insulation, allowing each component to be optimized independently for cost and disposal

Inventive Principle:
Principle #1Segmentation

3Volume of moving object

If flat vacuum insulation panels are produced with metal-coated casing, then thinner insulation is achieved, but production requires special equipment and becomes costly

Engineering Contradiction:
Improvepanel thicknessVSAvoidproduction complexity
Core Design Contradiction:
Volume of moving objectVSEase of manufacture

Solution Approach 1:

The patent uses flexible metalized or non-metalized foil coverings that can be applied to pre-formed corrugated cardboard cores using simple vacuum sealing equipment, avoiding the need for specialized metal coating equipment while achieving thin-panel vacuum insulation

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent pre-forms the corrugated cardboard core structure before applying the foil covering and evacuation, allowing the core to provide immediate dimensional stability and enabling simpler downstream processing compared to forming and coating operations in sequence

Inventive Principle:
Principle #10Preliminary action

4Object-generated harmful factors

If reused vacuum insulation boxes are implemented, then disposal cost is reduced, but a return system becomes necessary

Engineering Contradiction:
Improvedisposal costVSAvoidreturn system complexity
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The patent designs vacuum insulation packaging using inexpensive corrugated cardboard and simple foil coverings that can be easily disposed of or recycled, making single-use economically viable and eliminating the need for complex return and refurbishment systems

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

AI summary

The invention relates to a vacuum insulation element, in which a core is evacuated in a vacuum-tight envelope, as well as a vacuum insulation packaging and a vacuum insulation box, the core being formed by one or more elements having a shaping structure which forms an insulation volume which is in the envelope is evacuated. If necessary, the filling material in the usable volume can be vacuumed in one work step.
