Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If welded metallic structures are used for prefabricated units, then structural strength and stability are improved, but transport costs and atmospheric pollution increase due to the need to transport fully assembled units

Engineering Contradiction:

Improvestructural strengthVSAvoidatmospheric pollution

Core Design Contradiction:

StrengthVSObject-generated harmful factors

Solution Approach 1:

The prefabricated unit is divided into separate modular components (frame structure, walls, roof, floor) that can be transported independently and assembled on-site through connection elements, eliminating the need to transport fully welded structures and reducing transport-related pollution

Inventive Principle:

Principle #1Segmentation

2Stability of the object's composition

If welded metallic structures are used for prefabricated units, then structural stability is improved, but storage space requirements increase significantly

Engineering Contradiction:

Improvestructural stabilityVSAvoidstorage space

Core Design Contradiction:

Stability of the object's compositionVSVolume of stationary object

Solution Approach 1:

The unit is segmented into transportable modules that can be stored in compact configurations and assembled on-site, reducing storage space requirements while maintaining structural stability through connection elements

Inventive Principle:

Principle #1Segmentation

3Strength

If welded metallic structures are used for prefabricated units, then structural integrity is improved, but versatility and adaptability are limited

Engineering Contradiction:

Improvestructural integrityVSAvoidversatility

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The connection elements enable dynamic reconfiguration of the modular components, allowing the structure to be assembled, disassembled, and reconfigured for different applications while maintaining structural integrity through standardized connection mechanisms

Inventive Principle:

Principle #15Dynamics

4Strength

If fully assembled welded structures are transported, then structural strength is maintained, but transport costs increase

Engineering Contradiction:

Improvestructural strengthVSAvoidtransport costs

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The structure is segmented into modules that can be transported efficiently and assembled on-site, reducing transport costs while maintaining structural strength through connection elements that replicate welded joint performance

Inventive Principle:

Principle #1Segmentation
