Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If traditional insulation materials are used in insulated pipes, then the manufacturing process is simple, but the thermal insulation performance is insufficient

Engineering Contradiction:
Improvethermal insulation performanceVSAvoidstructure complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent applies composite materials by combining aerogel (a high-performance insulation material) with a flexible matrix material to create an insulation sheet. This composite structure achieves superior thermal insulation performance while maintaining flexibility and structural integrity, directly resolving the contradiction between insulation effectiveness and structural complexity.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent uses a flexible insulation sheet made from aerogel impregnated in a flexible matrix material. This flexible film approach allows the insulation layer to conform to the pipe surface and be easily wrapped around the pipe, improving thermal insulation while simplifying the manufacturing process through flexible handling and installation.

Inventive Principle:
Principle #30Flexible shells and thin films

2Loss of energy

If rigid insulation materials are used, then the insulation performance is high, but the handling and manufacturing flexibility is reduced

Engineering Contradiction:
Improvethermal insulation performanceVSAvoidhandling flexibility
Core Design Contradiction:
Loss of energyVSEase of operation

Solution Approach 1:

The patent employs a flexible insulation sheet composed of aerogel impregnated in a flexible matrix material. This flexible film can be easily wrapped around pipes of various diameters and configurations, maintaining high thermal insulation performance while significantly improving handling flexibility and ease of installation compared to rigid insulation materials.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent changes the physical state and properties of the insulation material by impregnating aerogel particles into a flexible matrix material. This parameter change transforms the rigid, brittle nature of pure aerogel into a flexible, conformable sheet that maintains the low thermal conductivity of aerogel while gaining the handling advantages of flexible materials.

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If the insulation sheet is wrapped loosely around the pipe, then the manufacturing is easy, but the insulation effectiveness and structural integrity are compromised

Engineering Contradiction:
Improvewrapping easeVSAvoidinsulation integrity
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent merges the insulation sheet with the pipe surface by wrapping the flexible aerogel-based sheet around the pipe and securing it with adhesive or mechanical fastening. This combination ensures the insulation layer remains firmly attached during handling and installation, maintaining both ease of manufacture through flexible wrapping and reliability through secure attachment.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The flexible nature of the aerogel-based insulation sheet allows it to be easily wrapped around the pipe surface conforming to its shape, while the flexibility enables secure attachment without creating stress concentrations. This flexible film approach ensures both easy manufacturing and reliable insulation integrity.

Inventive Principle:
Principle #30Flexible shells and thin films
