Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If complex folded sheet metal elements are used, then the structure can be assembled, but the construction and installation become difficult, long and costly
Solution Approach 1:
The structure is divided into modular profiled elements with standardized connection features. Each profiled element is a self-contained module with integrated connection points, allowing independent manufacturing and assembly. This segmentation transforms a complex folded sheet metal structure into simple, interchangeable modules that are easier to manufacture and install.
Solution Approach 2:
The connection elements are integrated directly into the profiled elements themselves rather than being separate components. The profiled elements incorporate built-in connection features (such as tabs, slots, or attachment points) that eliminate the need for separate folding and assembly operations, merging the structural and connective functions into a single manufactured component.
2Productivity
If traditional folded sheet metal structures are used, then electrical installations can be housed, but production time increases
Solution Approach 1:
The profiled elements are pre-manufactured with connection features already integrated into their structure. This preliminary action of incorporating connection elements during the extrusion process eliminates subsequent folding and assembly steps, significantly reducing both production time and installation time while maintaining the required structural integrity for housing electrical installations.
3Ease of manufacture
If complex assembly elements are used, then the structure can be joined, but the cost of realization increases
Solution Approach 1:
The profiled elements are designed with universal connection features that can accommodate various joining methods and configurations. The standardized interface allows the same profiled element design to be used in different positions and orientations, eliminating the need for complex, position-specific connection elements and reducing overall manufacturing cost while maintaining structural integrity.
