Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional construction methods are used for modular building structures, then structural strength and stability are ensured, but skilled labor and specialized transport conditions are required, leading to high costs
Solution Approach 1:
The joining system is segmented into distinct functional elements: a joining piece with multiple flanges for different panels, controlled clamping means for tightening, and fixing means for securing. This segmentation allows each component to be optimized independently and simplifies the overall assembly process by dividing the joining function into manageable parts.
Solution Approach 2:
The joining piece is designed as a multi-functional component that can connect different types of panels (first panel, second panel, third panel) through its multiple flanges. This universal design reduces the need for specialized joining components for each panel type, thereby reducing complexity while maintaining ease of manufacture across various modular building configurations.
2Manufacturing precision
If controlled clamping fixing means are used to assemble panels, then assembly precision and structural integrity are improved, but the device complexity increases
Solution Approach 1:
The controlled clamping fixing means is designed to enable workers to achieve precise panel assembly through straightforward tightening operations. The mechanism serves itself by providing built-in guidance and alignment features that ensure proper positioning during assembly, reducing the need for complex external alignment tools or highly skilled labor while maintaining high precision.
3Productivity
If prefabricated panels are used for modular construction, then construction speed and efficiency are improved, but transport and handling conditions become more restrictive
Solution Approach 1:
The modular building structure is divided into separate prefabricated panels that can be manufactured independently and transported separately. This segmentation allows each panel to be optimized for transport efficiency while maintaining the ability to assemble them into larger structures on-site, thereby improving productivity without excessive transport restrictions.

AI summary
The invention relates mainly to a metal joining part for assembling a structural unit for construction, which is essentially characterized in that it has three fastening flanks (11da, 11db, 11dc) that are able to fasten three panels (15, 16) to said joining part (11d) and are each provided with at least one smooth or tapped bore (11da', 11db', 11dc') which defines a fastening axis (Χ, Υ, Ζ) through clamping of the flank (11da, 11db, 11dc) in question against one of the three panels (15, 16), and in that the three fastening flanks (11da, 11db, 11dc) comprise a first fastening flank or central base (11da) that is able to press in a clamping fastening manner against a first panel, a second fastening flank or first fastening tab (11db) that is able to press in a clamping fastening manner against a second panel (15) and has a tapped bore (11db'), and a third fastening flank (11de) or second fastening tab (11de) that is able to press in a clamping fastening manner against a third panel (16) and comprises a smooth bore (11dc'). The invention also relates to a modular structural unit for construction that includes said metal joining part, three joined-together panels and a second metal part, the bores in the first and second metal parts on either side of a panel having opposite threads so as to allow fastening by controlled clamping of the panel. Finally, the invention relates to a modular construction structure that is made of a series of boxes, the tops of which consist of the structural unit defined above.
