Wind Turbine Blade Component Attachment Jig
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for manufacturing wind turbine blades require large manufacturing spaces and pose challenges in transportation due to the need for precise fitting of segmented blades, which is ensured by forming the entire blade with pin joints in an assembled state and then cutting it into segments, limiting flexibility and efficiency.
Innovation Solution
A system comprising a blade shell part support and a jig with a vertically displaceable component platform allows for precise positioning and attachment of wind turbine blade components, such as pin joint receiver boxes or spar beams, onto the blade shell parts, enabling separate manufacturing of blade segments with precise fitting without the need for full assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If pin joint components are attached with very high precision requirements, then blade segments fit together perfectly, but manufacturing complexity and space requirements increase significantly
Solution Approach 1:
The patent introduces a jig as an intermediary device between the component platform and the blade shell part. The jig includes positioning means that interfaces with both the platform and the component, acting as a mediator to transfer and maintain precise positioning information throughout the attachment process, thereby achieving high precision without requiring the entire system to be overly complex
Solution Approach 2:
The positioning system is segmented into distinct functional components: the component platform for holding the component, the jig with positioning means for precise location, and the blade shell part support. This segmentation allows each component to be optimized independently while working together to achieve the overall precision goal
2Area of stationary object
If blade segments are manufactured separately, then manufacturing space and transportation challenges are reduced, but achieving precise fit between segments becomes more difficult
Solution Approach 1:
The patent implements preliminary action by providing a component platform that pre-positions the blade component in a controlled environment before attachment. The platform holds the component in the correct position and orientation, and the jig's positioning means establishes precise location information in advance, ensuring that when the component is attached to the separately manufactured blade shell part, the segments will fit together with high precision
Solution Approach 2:
The patent replaces the traditional mechanical system of assembling entire blades with pin joints before cutting, with a new system using a vertically displaceable component platform and jig positioning mechanism. This substitution allows segments to be manufactured separately while achieving the same fitting precision through controlled positioning during attachment
3Adaptability or versatility
If component platform is vertically displaceable relative to jig base, then component positioning flexibility is improved, but system complexity increases
Solution Approach 1:
The patent applies dynamics by making the component platform vertically displaceable relative to the jig base. This dynamic capability allows the platform to be positioned at different heights to accommodate components of varying sizes and attachment requirements, providing flexibility without requiring a completely reconfigurable system. The vertical displacement mechanism adds adaptability while maintaining relatively simple system architecture

AI summary
The present invention relates to a system and method for attaching a wind turbine blade component to a surface of a wind turbine blade shell part at a component attachment position. The system comprises a blade shell part support for supporting the blade shell part, a jig comprising a jig base and a component platform for receiving and holding the wind turbine blade component in a first position above at least a part of the blade shell part, the component platform being arranged on the jig base and being at least vertically displaceable relative to the jig base by displacement means to allow the wind turbine blade component to be lowered from the first position to the component attachment position.
