Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If components like latches are installed in the vacuum adiabatic body, then the operational functionality is improved, but the adiabatic performance deteriorates due to heat transfer through mounting structures

Engineering Contradiction:

Improvecomponent mounting capabilityVSAvoidadiabatic performance

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

A component fastening portion is introduced as an intermediary structure between the vacuum chamber walls and external components. This fastening portion includes a fastening protrusion that extends into the vacuum space and a fastening hole formed in the vacuum chamber wall, creating a dedicated mounting interface that minimizes thermal conduction paths while enabling component installation.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The mounting structure is segmented into distinct components: the vacuum chamber wall, the fastening protrusion extending into the vacuum space, and the fastening hole. This segmentation allows the mounting function to be separated from the adiabatic wall structure, reducing thermal impact on the vacuum space.

Inventive Principle:

Principle #1Segmentation

2Ease of manufacture

If a simple vacuum chamber structure is used, then manufacturing ease is improved, but impact resistance deteriorates

Engineering Contradiction:

Improvestructural simplicityVSAvoidimpact resistance

Core Design Contradiction:

Ease of manufactureVSStrength

Solution Approach 1:

The vacuum adiabatic body employs a composite structure combining the vacuum chamber, adiabatic material layer, and integrated fastening portions. This composite design enhances impact resistance by creating a multi-layered structure that distributes mechanical stress while maintaining manufacturing feasibility through integrated formation of fastening protrusions during vacuum chamber fabrication.

Inventive Principle:

Principle #40Composite materials

3Loss of energy

If the vacuum space is extended beyond minimal requirements, then adiabatic performance is improved, but the risk of impact damage increases

Engineering Contradiction:

Improvethermal insulation performanceVSAvoidimpact damage risk

Core Design Contradiction:

Loss of energyVSObject-affected harmful factors

Solution Approach 1:

The fastening protrusion is designed with specific dimensional relationships: the length of the fastening protrusion extending into the vacuum space is controlled to be less than the distance from the fastening hole to the opposite wall. This beforehand design prevents the protrusion from creating weak points or stress concentration zones that could lead to impact damage, while still providing adequate component mounting capability.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)
