Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If leaves or doors are made in one piece according to the height and width of the access, then the structural integrity is maintained, but the manufacturing cost increases due to custom-made production

Engineering Contradiction:
Improvestructural integrityVSAvoidmanufacturing cost
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The leaf or door is divided into multiple modules that can be assembled together to form the complete structure. Each module can be manufactured independently using standardized processes, reducing custom-made production costs while maintaining the overall structural integrity through the connection system between modules

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If leaves or doors are manufactured in several adjacent modules, then the manufacturing cost decreases, but the device complexity increases due to complex interlocking fixing systems

Engineering Contradiction:
Improvemanufacturing costVSAvoidfixing system complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The structure is segmented into modules with simplified connection interfaces. The fixing system uses basic mechanical elements like pins or clips that can be easily manufactured and assembled, avoiding complex interlocking mechanisms while still enabling modular construction
