Solution Overview

Problem

Vacuum insulation panels are vulnerable to drilling, leading to a reduction in thermal insulation performance when holes are drilled for hanging objects, and existing solutions do not adequately protect these panels during drilling.

Innovation Solution

A multi-layer wall structure is introduced, comprising a vacuum insulation layer covered by a cladding partition and an anti-drill protection layer positioned between the vacuum insulation and the cladding partition to prevent damage during drilling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If vacuum insulation panels are used to reduce insulation thickness, then thermal insulation performance is improved, but vulnerability to drilling damage increases

Engineering Contradiction:

Improveinsulation thicknessVSAvoidresistance to drilling damage

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

A cladding partition is introduced as an intermediary protective layer between the vacuum insulation panel and the drilling tool. This partition absorbs the drilling action and prevents direct contact with the vulnerable vacuum insulation panel, thereby maintaining thermal performance while enabling mounting operations.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The wall assembly is constructed as a composite structure combining the vacuum insulation panel with the cladding partition. This composite design leverages the high insulation performance of the vacuum panel while the cladding partition provides mechanical protection against drilling damage.

Inventive Principle:

Principle #40Composite materials

2Reliability

If standard insulation materials are used, then drilling resistance is improved, but insulation thickness increases

Engineering Contradiction:

Improveresistance to drilling damageVSAvoidinsulation thickness

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The protective function is segmented from the insulation function. The cladding partition handles the mechanical protection and drilling resistance, while the vacuum insulation panel focuses solely on thermal insulation, allowing each component to be optimized for its specific purpose.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The drilling resistance property is extracted from the insulation material itself and transferred to the separate cladding partition. This allows the use of thin vacuum insulation panels without compromising drilling resistance, as the protection is provided by the dedicated partition layer.

Inventive Principle:

Principle #2Taking out (Extraction)

3Volume of moving object

If vacuum insulation panels are used, then space efficiency is improved, but ease of operation for mounting objects deteriorates

Engineering Contradiction:

Improvewall thicknessVSAvoidease of drilling for mounting

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The cladding partition serves as an intermediary that facilitates mounting operations. Users drill into the partition rather than the vacuum panel, making the process easier and safer while maintaining the space efficiency benefits of thin vacuum insulation.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The cladding partition acts as a flexible protective shell that can be drilled without compromising the underlying vacuum insulation. This thin film approach maintains overall wall thickness while providing operational flexibility for mounting objects.

Inventive Principle:

Principle #30Flexible shells and thin films
