Universal Wind Turbine Blade Clamping Jig
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jigs for wind turbine blades are not universal and require multiple specific jigs for blades of different lengths, widths, and shapes, leading to increased costs and lower use rates due to their inability to adapt to various blade configurations.
Innovation Solution
A universal jig with adjustable vertically-moving and horizontally-moving parts, adjustable pads, and positioning holes that allow for customizable clamping to match the shape and size of wind turbine blades, enabling flexible adjustment to accommodate blades of varying dimensions and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple specific jigs are used for blades of different lengths, widths, and shapes, then each blade type can be clamped accurately, but the number of jigs increases and costs increase
Solution Approach 1:
The patent designs a universal jig that can accommodate multiple blade types through adjustable components. The jig includes adjustable clamping arms and positioning mechanisms that can be reconfigured for different blade lengths, widths, and shapes, allowing one jig to perform the function of multiple specific jigs, thereby reducing the total number of jigs needed while maintaining clamping accuracy
Solution Approach 2:
The jig incorporates movable and adjustable components such as telescopic arms, adjustable clamping force mechanisms, and repositionable support elements. These dynamic features enable the jig to adapt its configuration to match different blade geometries, providing precise clamping for various blade types without requiring multiple fixed-purpose jigs
2Reliability
If multiple specific jigs are used for different blade types, then each blade can be clamped specifically, but the use rate of each jig decreases
Solution Approach 1:
The universal jig is designed to handle multiple blade types with a single device, increasing its utilization rate. By incorporating adjustable clamping mechanisms and reconfigurable positioning systems, the jig can be quickly adapted between different blade configurations, ensuring reliable clamping while maximizing productivity through reduced idle time between different blade types
3Manufacturing precision
If jigs are designed for specific blade shapes, then clamping precision is improved, but the adaptability to different blade configurations decreases
Solution Approach 1:
The jig employs dynamic adjustment mechanisms including movable clamping arms, adjustable positioning blocks, and reconfigurable support structures. These components can be repositioned and reconfigured to match different blade geometries, maintaining high clamping precision across various blade shapes while maximizing adaptability
Solution Approach 2:
The jig allows for changes in critical parameters such as clamping force, arm position, support location, and angle of contact. By adjusting these parameters, the jig can optimize its performance for different blade types, achieving both precision and versatility through parameter modification rather than requiring multiple fixed designs

AI summary
A universal jig is provided for clamping wind turbine blades. The jig has a rectangle-like shape forming a space for clamping a blade at the blade root or the blade body. The jig comprises a set of vertically-moving parts; a set of horizontally-moving parts; a plurality of adjusted pads; and a plurality of positioning parts. The vertically-moving parts comprise two upper connecting posts and two lower connecting posts sheathed with each other separately to form two length sides of the jig. The horizontally-moving parts comprise two left connecting posts and two right connecting posts. The adjusted pads are locked on the left and the right connecting posts. The positioning parts are locked at the upper and the lower connecting posts of the length sides of the jig and are locked at the left and the right connecting posts of the width sides of the jig.
