Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If metallic profiles are used to form the wall structure, then the profile provides good mechanical strength and structural stability, but the metallic profiles form heat bridges that allow considerable heat transfer

Engineering Contradiction:

Improvestructural strengthVSAvoidheat transfer

Core Design Contradiction:

StrengthVSLoss of energy

Solution Approach 1:

The web is divided into multiple web elements (at least two) that are connected to the first and second limbs. This segmentation creates thermal gaps between the web elements, breaking the continuous heat bridge path while maintaining structural connection between limbs.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The profile combines metallic limbs with non-metallic web elements to create a composite structure. The metallic limbs provide structural strength while the non-metallic web elements provide thermal insulation, eliminating the heat bridge effect of continuous metallic construction.

Inventive Principle:

Principle #40Composite materials

2Stability of the object's composition

If metallic profiles are used for the wall structure, then the profile maintains structural integrity, but sound is transmitted through the profile without disruption

Engineering Contradiction:

Improvestructural integrityVSAvoidsound transmission

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The web is segmented into multiple separate web elements rather than being a continuous metallic piece. This segmentation disrupts the sound transmission path through the profile while the limbs remain structurally intact, achieving sound decoupling without compromising structural integrity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The composite construction with metallic limbs and non-metallic web elements creates acoustic isolation. The non-metallic web elements do not conduct sound waves effectively, reducing sound transmission through the profile while maintaining the structural framework.

Inventive Principle:

Principle #40Composite materials

3Ease of manufacture

If a continuous web is used to connect the two limbs, then the profile is simple to manufacture, but thermal decoupling of the limbs is not achieved

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidthermal decoupling

Core Design Contradiction:

Ease of manufactureVSLoss of energy

Solution Approach 1:

The web is segmented into multiple web elements that can be manufactured separately and then connected to the limbs. This segmentation achieves thermal decoupling by creating gaps in the thermal path, while the manufacturing process remains relatively simple through standardized connection methods.

Inventive Principle:

Principle #1Segmentation

4Reliability

If additional connection means or adhesive connections are provided between web elements and limbs, then the connection is secure, but the production process becomes more complex and expensive

Engineering Contradiction:

Improveconnection reliabilityVSAvoidproduction complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The web elements are designed with self-fastening features that allow them to connect directly to the limbs without requiring additional connection means or adhesive applications. The web elements themselves provide the connection function, simplifying the production process while maintaining reliable connections.

Inventive Principle:

Principle #25Self-service
