Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If large-size wind turbines with three blades and horizontal axis are used, then energy generation efficiency is improved, but structural stability deteriorates due to significant structural strains requiring deep foundations
Solution Approach 1:
The patent inverts the conventional horizontal-axis turbine design by adopting a vertical-axis configuration. This inversion fundamentally changes the structural load distribution, eliminating the need for deep foundations and complex support structures while maintaining energy generation efficiency. The vertical orientation allows the turbine to withstand wind forces more effectively without compromising structural stability.
Solution Approach 2:
The patent incorporates adjustable blade pitch mechanisms and variable speed control systems that allow the turbine to dynamically adapt to changing wind conditions. This dynamic capability enables the turbine to optimize its performance across a wide range of wind speeds while maintaining structural integrity, resolving the contradiction between efficiency and stability.
2Productivity
If large-size wind turbines with considerable height are used, then energy generation efficiency is improved, but adaptability deteriorates due to unsuitability for floating platforms and unstable terrain
Solution Approach 1:
By inverting from horizontal-axis to vertical-axis design, the turbine achieves a compact footprint that is suitable for floating platforms and unstable terrain. The vertical configuration eliminates the need for tall, rigid support structures, allowing installation on diverse surfaces including water, sand, and uneven ground where conventional turbines cannot be deployed.
Solution Approach 2:
The patent designs a universal turbine system that can be installed in multiple environments including land-based, floating, and urban settings. The modular construction and adaptable foundation requirements enable the same turbine design to function across various installation contexts, significantly improving versatility without sacrificing energy generation capability.
3Stability of the object's composition
If conventional wind turbines are installed far from built-up areas, then structural stability is improved, but harmful factors worsen due to reduced accessibility for maintenance and lower utility value
Solution Approach 1:
The vertical-axis configuration with compact dimensions allows turbine components to be positioned at accessible heights, eliminating the need to locate turbines far from human activity. The inverted design enables maintenance personnel to easily access rotating and stationary components without requiring specialized high-altitude equipment or remote locations.
Solution Approach 2:
The patent applies local quality optimization by positioning critical maintenance points at ergonomically accessible heights and orientations. The blade pitch adjustment mechanisms, bearing assemblies, and electrical connections are strategically located for easy access, while the overall structural stability is maintained through the vertical-axis design. This localized optimization allows urban installation without compromising maintenance accessibility.
4Adaptability or versatility
If small or medium-sized plants with vertical axis are used, then adaptability is improved, but productivity deteriorates due to unresolved technical and functional problems
Solution Approach 1:
The patent merges the advantages of both horizontal and vertical-axis designs into a unified system. It combines the structural stability and efficiency of horizontal-axis turbines with the adaptability and compact footprint of vertical-axis turbines. This synthesis resolves the technical and functional problems that have limited small-scale vertical-axis turbines, achieving both high productivity and broad adaptability in a single integrated design.

AI summary
A system for generating electric energy from wind or hydraulic energy includes a turbine, and an electric energy generating device to which the turbine is connected through a shaft along a first axis. The turbine includes at least one blade, configured to perform a first rotary movement with respect to the first axis, and a second rotary movement with respect to a second axis, coinciding with the axis of the blade itself. This provides a system with structural features allowing high efficiency, facilitating installation in various environmental contexts, without risk of damage for the respective operational and structural integrity, at the same time. Additionally, the system has an essentially reduced environmental impact, as well as a low noise level so that it can be installed in an urban context or in any case close to built-up areas, i.e. near houses or buildings.
