Wind Turbine Blade Tip-to-Root Packaging for Compact Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transportation and storage of large wind turbine blades are challenging due to their size and fragility, leading to potential damage during transport and mounting, and existing solutions face logistical issues with restrictions on load size, height, and distance between supports, making current methods costly and inefficient.
Innovation Solution
A method and system for transporting and storing wind turbine blades by attaching root end frames to the root ends and tip end frames to the tip ends, arranging the blades in a 'tip-to-root' configuration with opposite orientations to reduce stress on the most fragile areas, allowing for closer frame placement and easier compliance with transport regulations, and optionally using intermediate protection members for additional support.

Engineering Contradiction Analysis
1Length of moving object
If blades are transported in a conventional single-direction arrangement, then the transport system is simple, but the distance between support frames becomes too large for long blades, violating transport regulations
Solution Approach 1:
The patent transitions from a single-direction linear arrangement to a bidirectional tip-to-root configuration where blades extend in opposite directions from central support frames. This dimensional reorganization allows the support frames to be positioned at the root ends while blade tips extend beyond, effectively reducing the unsupported span and complying with transport regulations for long blades
2Reliability
If support frames are placed at the tip ends of blades, then the blades can be supported, but the tip ends are mechanically most fragile and may be damaged
Solution Approach 1:
The patent inverts the conventional support arrangement by placing support frames at the root ends rather than tip ends of blades. In the tip-to-root configuration, root end frames support one blade while tip end frames support the adjacent blade, reversing the typical support location to avoid damaging the mechanically vulnerable tip sections
3Reliability
If multiple blades are transported using separate packaging systems, then each blade is individually protected, but the transport costs increase significantly
Solution Approach 1:
The patent merges multiple blade transport functions into a single integrated packaging system. Multiple blades are arranged in a tip-to-root configuration and secured together with straps, allowing simultaneous transport of several blades on one vehicle rather than requiring separate packaging for each blade, thereby reducing transport costs while maintaining protection
4Volume of moving object
If blades are arranged in a compact tip-to-root configuration, then storage space is optimized, but the frame placement becomes more complex
Solution Approach 1:
The patent segments the support structure into distinct root end frames and tip end frames that can be independently positioned and secured. This segmentation allows the complex tip-to-root configuration to be assembled in modular sections, with each frame type performing a specific function, thereby managing the complexity through systematic division of the support system

AI summary
A transportation and storage system for at least two wind turbine blades and comprising a first wind turbine blade and a second wind turbine blade is described. The wind turbine blades each having a root end and a tip end, said system comprising a packaging system that is adapted to placing the first wind turbine blade so that the tip end of the first wind turbine blade points in a first direction, and placing the second wind turbine blade so that the tip end of the second wind turbine blade points in a second direction, which is substantially opposite to the first direction. The tip end of the second wind turbine blade extends beyond the root end of the first wind turbine blade, and the tip end of the first wind turbine blade extends beyond the root end of the second wind turbine blade, when the first and the second wind turbine blades are arranged in the packaging system.
