Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching panels to wind turbine blades, such as using C-clamps, result in non-uniform pressure distribution, are cumbersome and inefficient, particularly for non-planar surfaces, leading to suboptimal bonding and increased application time.
Innovation Solution
A method and tool using at least two rollers to apply uniform pressure along the surface of the wind turbine blade, compatible with both planar and non-planar surfaces, ensuring secure bonding by moving the rollers continuously and applying adhesive uniformly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If C-clamps are used to apply pressure to panels, then localized pressure can be applied, but the pressure distribution becomes non-uniform and bonding quality deteriorates
Solution Approach 1:
The pressure application tool is divided into multiple rollers (at least two rollers) that distribute pressure across multiple contact points along the panel surface. This segmentation transforms the single localized pressure point of C-clamps into multiple distributed pressure zones, achieving uniform pressure distribution across the entire bonding surface.
Solution Approach 2:
Rollers are introduced as intermediary elements between the pressure application tool and the panel surface. These rollers act as mediators that transmit and distribute the applied force uniformly across the bonding interface, eliminating the non-uniform pressure distribution caused by direct C-clamp contact.
2Force
If C-clamps are used for panel attachment, then pressure can be applied, but the process becomes tedious and time-consuming
Solution Approach 1:
Multiple pressure application functions are merged into a single tool structure. The pressure application device integrates multiple rollers and pressure application points into one unified tool that can apply pressure across the entire panel surface simultaneously, eliminating the need for sequential C-clamp placement and significantly reducing application time.
Solution Approach 2:
The pressure application process is made continuous through the use of multiple rollers that can be moved along the panel surface in a continuous motion. This continuous pressure application eliminates the intermittent nature of C-clamp attachment, maintaining constant bonding pressure throughout the process and improving overall productivity.
3Force
If C-clamps are used to attach panels, then pressure can be applied, but it is difficult to use with non-planar panels or surfaces
Solution Approach 1:
The pressure application tool incorporates movable and adjustable rollers that can adapt to different surface geometries. The rollers can be positioned and moved along the panel surface, allowing the tool to accommodate non-planar surfaces and various panel shapes, providing versatile adaptability that rigid C-clamps cannot achieve.
Solution Approach 2:
The tool allows for adjustment of pressure distribution parameters across different locations on the panel surface. By varying the position, number, and pressure applied by different rollers, the system can adapt to different surface geometries and panel configurations, achieving optimal bonding on both planar and non-planar surfaces.
