Solution Overview

Problem

Conventional insulating sleeves for containers are rigid and inflexible, limiting design adaptability and preventing subsequent or additional attachments, as the insulating material must match the shape of the outer sleeve, restricting flexibility and usability on containers with varying geometries.

Innovation Solution

A device featuring a flexible outer layer with a vacuum insulation element that can be fastened to a container wall, allowing for subsequent or additional attachment, comprising a textile material with adjustable thickness and flexibility, along with separate stiffening elements and an inner layer for enhanced insulation and adaptability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a rigid outer sleeve is used to provide stability and shape to the insulating material, then the structural stability is improved, but the adaptability to different container geometries deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidadaptability to container geometries
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent replaces the conventional rigid outer sleeve with a flexible outer layer made of textile material. This flexible outer layer can adapt to different container geometries while still providing structural stability through the combination with stiffening elements and vacuum insulation panels, thus resolving the contradiction between stability and adaptability.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The outer layer is designed to be dynamically flexible rather than statically rigid, allowing it to conform to various container shapes. The flexibility is controlled through material selection and thickness variation, enabling the insulation device to adapt to different applications while maintaining adequate structural integrity.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If the insulating material is adapted to match the shape of the outer sleeve, then the manufacturing precision is improved, but the ease of operation for subsequent adjustments deteriorates

Engineering Contradiction:
Improveshape conformityVSAvoidease of subsequent adjustments
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The insulation device is divided into modular components: flexible outer layer, stiffening elements, and vacuum insulation panels. These segments can be independently manufactured and assembled, allowing precise shaping of each component while enabling easy reconfiguration and adjustment of the overall structure for different applications.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent allows for variation in parameters such as outer layer thickness, stiffening element placement, and vacuum panel dimensions to optimize both manufacturing precision for specific applications and ease of adjustment. The flexible nature of the outer layer enables parameter adjustments without requiring complete remanufacturing.

Inventive Principle:
Principle #35Parameter changes

3Loss of energy

If a thick outer layer is used to achieve sufficient thermal insulation, then the insulation effectiveness is improved, but the flexibility deteriorates

Engineering Contradiction:
Improvethermal insulation effectivenessVSAvoidflexibility
Core Design Contradiction:
Loss of energyVSAdaptability or versatility

Solution Approach 1:

The patent employs a composite structure combining a relatively thin flexible textile outer layer with rigid vacuum insulation panels and stiffening elements. This composite approach achieves high thermal insulation effectiveness (low energy loss) while maintaining flexibility, as the vacuum panels provide superior insulation per unit thickness compared to conventional materials.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The outer layer is designed as a thin flexible textile that provides structural continuity and flexibility, while the actual thermal insulation function is primarily performed by the vacuum insulation panels. This separation of functions allows the outer layer to remain thin and flexible while achieving sufficient overall insulation effectiveness.

Inventive Principle:
Principle #30Flexible shells and thin films
