Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional connection structures are used for split tower sections, then the assembly process becomes simpler, but positioning accuracy decreases and gaps are generated causing water ingress
Solution Approach 1:
The patent introduces a connection structure comprising a first connection piece with a first connecting plate and a second connection piece with a second connecting plate. These connection pieces act as intermediaries between the tower sections, providing precise positioning features (positioning grooves, positioning bumps) that ensure accurate alignment and eliminate gaps, thereby preventing water ingress while maintaining manageable assembly complexity through modular design.
2Strength
If the tower diameter is increased to improve bearing capacity, then the tower strength increases, but transportation becomes difficult
Solution Approach 1:
The patent divides the large-diameter tower into multiple separable sections that can be transported independently. The connection structure enables these sections to be assembled on-site with high precision through positioning mechanisms (positioning grooves, positioning bumps, and guide pins), ensuring that the segmented tower achieves the same structural integrity and bearing capacity as a monolithic tower while solving transportation constraints.
3Productivity
If rapid assembly is implemented for split tower sections, then assembly time decreases, but positioning accuracy and sealing performance deteriorate
Solution Approach 1:
The connection structure incorporates pre-designed positioning features (positioning grooves, positioning bumps, guide pins) that automatically align tower sections during assembly. This preliminary configuration of positioning elements ensures that even during rapid assembly, the sections achieve accurate alignment and proper sealing without requiring time-consuming manual adjustment, thus maintaining both speed and precision.
