Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional substructure with multiple columns and connecting members is used, then the structural strength is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the functions of multiple columns and connecting members into a single integrated substructure. The U-shaped substructure combines the support function of columns with the connection function of members, eliminating the need for separate components while maintaining structural strength and reducing complexity.
Solution Approach 2:
The U-shaped substructure serves multiple functions simultaneously: it provides structural support, connects the floating body to the wind turbine, and offers mounting points for equipment. This multi-functionality reduces the overall number of components needed in the system.
2Ease of manufacture
If a compact substructure is used, then the manufacturing cost is reduced, but the vessel access becomes difficult
Solution Approach 1:
The U-shaped substructure extends in the longitudinal dimension of the floating body, creating open space on both sides. This dimensional arrangement allows vessels to access the wind turbine from either side without requiring a complex, space-consuming layout.
3Productivity
If the floating body has high motion performance, then the power generation efficiency is improved, but the structural complexity increases
Solution Approach 1:
The floating body is segmented into distinct functional modules: the U-shaped substructure, the floating platform, and the wind turbine assembly. This segmentation allows each module to be optimized independently for its specific function while maintaining overall system performance.
