Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high costs and weather dependence of traditional offshore wind turbine installation methods, which require large cranes and ships, make it economically unfeasible to install large power wind systems offshore.
Innovation Solution
A telescopic support tower design that allows for on-site assembly and installation without the need for large lifting means, featuring a first elongated component and a second slidably coupled component, moving and blocking mechanisms, and an anti-falling system, enabling quick and cost-effective installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional installation methods using large cranes and ships are employed, then the support tower can be installed offshore, but the installation costs become extremely high and the process is strongly influenced by weather conditions
Solution Approach 1:
The support tower is divided into multiple telescopic sections that can be assembled in a compact configuration for transport and then extended on-site to the full height. This segmentation allows the tower to be transported on standard vessels without requiring large cranes for installation, thereby reducing installation costs while maintaining reliability
Solution Approach 2:
The support tower employs a telescopic mechanism with movable sections that can be extended and retracted. This dynamic structure allows the tower to transform from a compact transport state to a full operational height, eliminating the need for traditional crane-based installation methods and reducing dependence on weather conditions
2Ease of operation
If traditional installation methods using large cranes are employed, then the support tower can be positioned vertically, but the device complexity and installation cost increase significantly
Solution Approach 1:
The telescopic sections of the support tower are nested within each other during transport, with each section containing the next. This nesting principle allows the entire tower structure to be compacted to a fraction of its operational height, enabling transport on standard vessels and simplifying installation equipment requirements while maintaining ease of operation through automated extension mechanisms
3Ease of manufacture
If the support tower is designed with telescopic sections, then the installation cost and weather dependence are reduced, but the structural complexity of the tower increases
Solution Approach 1:
The telescopic mechanism serves multiple functions: it enables compact transport configuration, facilitates simplified installation without large cranes, provides structural stability during operation, and allows for potential height adjustment. This multi-functionality justifies the increased structural complexity by delivering significant benefits in installation cost reduction and weather independence

AI summary
A support tower, particularly for a wind turbine. The support tower has at least a first elongated component which is internally hollow and at least a second elongated component which is slidably coupled to the at least a first elongated component and movable relative to the at least a first elongated component at least between a retracted position. The second elongated component is at least partially inserted in the at least a first elongated component, and an extracted position, where the at least a second elongated component is substantially extracted from the at least a first elongated component. A moving device for moving the second elongated component from the retracted position to the extracted position, and vice versa, and a blocking device configured to allow the at least a second elongated component to be blocked in the extracted position, are also provided.
