Modular Platform Assembly for Wind Turbine Tower Diameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wind turbine platform assemblies are difficult to install due to their weight and require significant redesign for different tower diameters, leading to increased construction costs and time, as they are tailored to specific dimensions and require numerous components for mounting.
Innovation Solution
A modular platform assembly with a core structural support grid and adjustable platform extension panels that can be configured to fit varying tower diameters, allowing for easy assembly and versatility across different wind turbine towers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional steel beams and plate platforms are used, then structural strength is sufficient, but the platform becomes heavy and difficult to install requiring crane lifting
Solution Approach 1:
The platform is divided into multiple modular panels that can be assembled together to form the complete platform structure. Each panel is a separate, lighter component that can be manually handled and positioned, then connected to adjacent panels through interlocking features, eliminating the need for heavy steel beams and crane installation while maintaining structural integrity
Solution Approach 2:
The modular panels are designed with standardized dimensions and interconnection features that allow them to be used in various configurations for different platform sizes and locations within the tower. The same panel design can serve multiple functions across different installation positions, reducing the need for custom-heavy components for each specific location
2Manufacturing precision
If conventional platforms are tailored to specific tower diameters, then precise fit is achieved, but redesign is necessary for each tower design increasing costs and time
Solution Approach 1:
The platform system incorporates adjustable support legs or positioning mechanisms that allow the platform assembly to be dynamically adapted to different tower inner diameters. The support legs can be extended or retracted, or repositioned along the platform perimeter, enabling the same platform design to maintain precise fit across varying tower dimensions without requiring redesign
Solution Approach 2:
The platform design utilizes adjustable parameters such as support leg length, panel spacing, and circumferential positioning that can be modified to accommodate different tower diameters. By changing these parameters rather than the fundamental platform geometry, the same platform design achieves precise fit for multiple tower sizes, eliminating the need for custom designs
3Reliability
If numerous bosses and clip plates are used to mount the platform, then secure attachment is achieved, but installation becomes time-consuming and cost-intensive
Solution Approach 1:
The mounting features are integrated directly into the platform panel structure itself rather than being separate components. The panels include built-in attachment elements such as recesses, protrusions, or direct mounting flanges that combine the functions of structural support and secure attachment, eliminating the need for separate bosses and clip plates and significantly reducing installation steps
4Reliability
If conventional platforms are fixed by welding or bolts to tower walls, then secure mounting is achieved, but installation complexity and time increase
Solution Approach 1:
The complex mounting system is extracted and replaced with simplified attachment mechanisms that are either pre-assembled with the platform panels or require minimal field assembly. The design removes unnecessary mounting components and steps, retaining only the essential secure attachment function through streamlined features such as clamp-style mounts, snap-fit connections, or simplified bolting patterns

AI summary
A modular platform assembly for a wind turbine tower includes a core platform sub-assembly having an underlying structural support grid. A plurality of platform extension panels are disposed circumferentially around at least a portion of a perimeter of the core platform sub-assembly. Support extensions are configured on the support grid at a plurality of circumferential positions around the core platform sub-assembly, with the platform extension panels supported by the support extension. The support extensions are mountable to a wall within a wind turbine tower and are variably positional on the support grid so at to vary the effective diameter of the support grid.
