Wind Turbine Tower Section Platform Assembly Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wind turbine tower installations are costly and time-consuming due to the difficulty in securing platforms to tower sections, which often result in safety issues caused by gaps between the platform and the tower wall, requiring additional components to cover these gaps.
Innovation Solution
A tower section design with a preassembled power module and integrated platform assembly, where the platform assembly has a larger diameter than the tower flange, allowing for easier installation and reducing gaps, along with extendable platform extension panels to further minimize gaps and enhance safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional steel beams and components are used to mount platforms to tower sections, then platforms can be installed, but installation becomes difficult and costly with significant time consumption
Solution Approach 1:
The platform assembly is pre-assembled with the tower section in a factory setting before delivery to the installation site. This preliminary assembly eliminates the need for complex on-site installation of multiple separate components, significantly reducing installation time and complexity while maintaining structural integrity
Solution Approach 2:
The platform assembly is integrated as a single unified component with the tower section, combining what were previously separate elements (platform, support structures, mounting hardware) into one pre-assembled unit. This merging simplifies the installation process by reducing the number of assembly steps required on-site
2Ease of operation
If platforms are designed with smaller inner diameter to fit past tower flanges, then platforms can be installed, but gaps are created between platform and tower wall causing safety issues
Solution Approach 1:
The platform assembly is pre-configured with the correct diameter and positioning features before installation. This preliminary preparation ensures the platform is designed to fit properly against the tower wall from the outset, eliminating gaps that would compromise safety without requiring complex adjustments during installation
Solution Approach 2:
The platform assembly uses a larger diameter design that changes the geometric parameters of the installation. By increasing the platform diameter to match or exceed the tower flange diameter, the design eliminates the need to reduce platform size, thereby preventing gap formation while maintaining installation feasibility through the preassembled configuration
3Reliability
If additional components are installed on platforms to cover gaps, then safety issues are addressed, but installation becomes more costly and time-consuming
Solution Approach 1:
The platform assembly is integrated as a single unified component with the tower section, combining what were previously separate elements (platform, support structures, mounting hardware) into one pre-assembled unit. This merging simplifies the installation process by reducing the number of assembly steps required on-site
Solution Approach 2:
The design extracts and eliminates the need for additional gap-covering components by redesigning the platform assembly itself. Instead of adding separate safety components, the solution removes the root cause (gaps) through proper preliminary design and sizing of the integrated platform assembly

AI summary
Tower sections for towers of wind turbines and methods for installing towers of wind turbines are disclosed. A tower includes a preassembled power module having a first cross-sectional area. The tower section includes a wall having an inner surface and an outer surface. The inner surface defines a tower interior and has a first diameter. The tower section further includes a tower flange extending from the wall into the tower interior and having a second diameter less than the first diameter. Further, the tower section includes a platform assembly affixed to the wall and having a third diameter greater than the second diameter. The platform assembly defines an aperture having a second cross-sectional area greater than the first cross-sectional area.
