Solution Overview
Problem
Existing support structures for electric energy eolian generators are inefficient and complex, requiring hydraulic or oleo-dynamic systems for installation, which are costly and burdensome, and do not ensure balanced support under varying atmospheric conditions.
Innovation Solution
A modular support structure using a system of nautical rigging stays and ballast weights distributed around a central vertical section bar, allowing for easy installation with common lifting equipment and ensuring balanced operation under strong winds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If hydraulic or oleo-dynamic systems are used for installation, then the support structure can be installed, but the installation becomes costly and burdensome
Solution Approach 1:
The patent removes hydraulic or oleo-dynamic systems from the installation process entirely. Instead, it uses a modular support structure with ballast weights that can be installed using only common lifting equipment, thereby extracting the complex installation systems while maintaining installation capability
Solution Approach 2:
The patent replaces expensive hydraulic/oleo-dynamic installation systems with simple, inexpensive ballast weights and modular components that can be installed and potentially reconfigured or relocated using basic equipment
2Device complexity
If a modular support structure is used, then installation complexity is reduced, but the ability to withstand strong winds may be compromised
Solution Approach 1:
The patent uses ballast weights as counterweights to provide stability and wind resistance. The ballast weights are distributed around the central vertical section bar to create a balanced structure that can withstand strong winds while maintaining modular simplicity
Solution Approach 2:
The support structure is divided into modular components including a central vertical section bar, inclined section bars, and ballast weights that can be independently positioned and adjusted. This segmentation allows for simplified assembly while maintaining overall structural strength through proper configuration
3Stability of the object's composition
If ballast weights are distributed around the central vertical section bar, then balanced support is achieved, but the number of components increases
Solution Approach 1:
The ballast weights serve multiple functions: they provide stability through distributed mass, act as counterweights against wind forces, and serve as anchor points for the inclined section bars. This multi-functionality reduces the need for separate stabilization components

Function Achieved in This Case
The solution provides a cost-effective, efficient, and reliable support system that reduces installation complexity and costs by using common lifting equipment, ensuring stable operation of eolian generators under various conditions without the need for expensive hydraulic systems.
Implementation Method 1
a system of nautical rigging stays 51-60, which join to each other all the component parts of the support structure, and which are stretched by a system of rigging devices 61, 62, in order to raise the different component parts from their initial operative positions, in which the ballasts are arranged around, to a final operative position
