Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Long wind turbine blades are heavy, inefficient at low wind conditions, and difficult to manufacture and transport due to their size and weight, necessitating a need for lightweight, efficient, and suitable methods for assembling and transporting large wind turbine blades.
Innovation Solution
A system and method for assembling spanwise segments of wind turbine blades using transport platforms with guide structures and motion devices to align and attach segments, employing a zig-zag bond line for strong bonding and using clamps to prevent delamination, allowing for efficient transportation and assembly of large blades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wind turbine blades are made longer to produce more energy, then energy production efficiency is improved, but weight and inertia increase significantly
Solution Approach 1:
The wind turbine blade is divided into multiple segments that can be manufactured separately and then assembled together using bonding techniques. This segmentation allows each segment to be lighter and easier to manufacture while maintaining the overall blade length for improved energy production efficiency
2Productivity
If wind turbine blades are made longer to capture more wind energy, then energy production efficiency is improved, but manufacturing difficulty increases
Solution Approach 1:
The blade is segmented into multiple manageable sections that can be manufactured using standard processes and then assembled. This reduces manufacturing complexity compared to producing a single long blade while maintaining the desired blade length for improved energy capture
Solution Approach 2:
The segments are pre-manufactured and prepared separately before final assembly. This preliminary manufacturing allows for quality control and optimization of each segment while simplifying the overall manufacturing process compared to producing a single long blade
3Productivity
If wind turbine blades are made longer to increase energy capture, then energy production efficiency is improved, but transportation difficulty increases
Solution Approach 1:
The blade is divided into multiple segments that can be transported separately using standard transportation methods. This segmentation makes transportation feasible for long blades that would otherwise be too large and heavy to move, while maintaining the ability to assemble them into long blades for improved energy production
4Device complexity
If segments are assembled using traditional bonding methods, then assembly simplicity is maintained, but bonding strength is insufficient
Solution Approach 1:
The bonding process uses composite bonding techniques that combine multiple bonding agents and methods to achieve strong, durable joints between segments. This creates a robust bond that can withstand the mechanical stresses on wind turbine blades while maintaining a relatively simple assembly process

AI summary
Systems and methods for transporting and assembling segmented wind turbine blades are disclosed. A system in accordance with a particular embodiment includes a first transport device that is moveable as a unit from a blade fabrication site to a blade assembly site. The first transport device has a first carrier positioned to carry a first spanwise segment of a wind turbine blade with the first segment aligned along a first blade axis. This system can further include a second transport device movable as a unit from a blade fabrication site to the blade assembly site, with the second transport device having a second carrier positioned to carry a second spanwise segment of the wind turbine blade with the second segment aligned along a second blade axis. The system can still further include a guide structure carried by at least one of the first and second transport devices.
