Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If building elements for thermal insulation are designed with complex assembly requirements, then thermal insulation performance is improved, but ease of manufacture and transportation deteriorates

Engineering Contradiction:

Improvethermal insulation performanceVSAvoidease of manufacture and transportation

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The building element is divided into separate components: an insulating body and a rail structure. The insulating body can be manufactured independently and transported separately, then assembled with the rail structure on-site. This segmentation enables easy manufacturing and transportation while maintaining thermal insulation performance through the dedicated insulating body component.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The rail structure acts as an intermediary element that provides mechanical support and assembly guidance. It includes features like recesses that receive the insulating body and protrusions that engage with the building part, simplifying the assembly process while ensuring proper thermal insulation installation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If building elements require complex assembly, then structural stability is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvestructural stabilityVSAvoidease of assembly

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

By separating the insulating body from the rail structure, the assembly operation is simplified. The insulating body is inserted into recesses in the rail structure, which is then attached to the building part. This segmented approach maintains structural stability while reducing assembly complexity compared to monolithic designs.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The rail structure includes self-aligning features such as recesses and protrusions that automatically position the insulating body correctly during assembly. This self-service mechanism ensures proper alignment and stable construction without requiring complex alignment procedures or specialized tools.

Inventive Principle:

Principle #25Self-service

Solution Approach 1:

The building element is segmented into an insulating body and a rail structure that work together to transfer forces. The rail structure includes reinforcement elements and attachment features that provide force transfer capability, while the insulating body maintains thermal performance. This segmentation enables easy manufacturing and transportation of individual components while achieving integrated force transfer when assembled.
