Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a traditional building element structure is used, then structural support is provided, but installation of insulation layers becomes difficult and complex

Engineering Contradiction:
ImproveInstallation of insulation layerVSAvoidStructure complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The building element is divided into distinct functional segments: an insulating body portion and a separate rail structure portion. The rail structure itself is segmented into outer rails and inner rails that can be assembled together to form channels. This segmentation allows the insulation layer to be easily installed within the modular components without requiring complex integrated structures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rail structure acts as an intermediary component between the insulating body and the building parts. It provides a structured framework that facilitates the installation of insulation layers while maintaining structural support. The rail structure mediates between the need for simple insulation installation and the requirement for structural integrity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If insulation layers are added to rail structures, then thermal insulation is improved, but manufacturing complexity increases

Engineering Contradiction:
ImproveThermal insulation performanceVSAvoidManufacturing process
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The rail structures are pre-formed with channel configurations designed to receive insulation layers. The outer rails and inner rails are manufactured separately with complementary shapes that create the insulation receiving space. This preliminary structuring of the rail components allows insulation layers to be easily added during assembly without requiring complex manufacturing processes for integrating the insulation.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If a multipart rail structure is used, then insulation layer installation is facilitated, but structural strength may be reduced

Engineering Contradiction:
ImproveInsulation layer installationVSAvoidStructural strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The outer rails and inner rails are merged through connection elements to form a unified rail structure assembly. This combined structure provides both the structural strength needed for load-bearing applications and the channel configuration necessary for easy insulation layer installation. The merging of components achieves both structural integrity and operational ease.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The rail structure employs composite construction combining different materials and components - outer rails, inner rails, connection elements, and insulation layers work together as a composite system. This composite approach allows each component to contribute its specific properties, with the overall assembly providing both strength and ease of insulation installation.

Inventive Principle:
Principle #40Composite materials
