Hanging Scaffold for Wind Turbine Blade Moulds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing techniques for wind turbine blades require cumbersome and costly temporary scaffolds for ground-level access, which are inflexible and inefficient in terms of space utilization and cost-effectiveness.
Innovation Solution
A hanging scaffold system is attached to the mould structure, allowing for flexible height adjustment and space-saving design, with support arms and brackets for easy installation and upgrade of existing moulds, enabling workers to access the mould from above ground level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If temporary scaffolds are placed on the ground for worker access, then worker access to the mould is enabled, but space utilization is reduced and installation becomes cumbersome
Solution Approach 1:
The scaffold is transitioned from ground-level placement to suspension from the mould structure above, utilizing the vertical dimension. This allows workers to access the mould from an elevated position rather than requiring ground-level floor space, thereby resolving the contradiction between ease of operation and area utilization.
2Ease of operation
If ground-level scaffold placement is used, then worker access is provided, but the system becomes inflexible and costly
Solution Approach 1:
The scaffold system is made adjustable and movable by suspending it from the mould structure rather than fixing it to the ground. The support arms can be positioned at different locations on the mould structure, allowing the scaffold to be easily reconfigured and adapted to different mould configurations, thereby improving flexibility and adaptability.
3Strength
If traditional ground-based scaffolds are used, then structural support is provided, but installation complexity and cost increase
Solution Approach 1:
The scaffold support structure is merged with the existing mould structure by suspending the scaffold from the mould's rigid frame. This integration eliminates the need for separate ground-based support structures and reduces installation complexity, while the mould structure itself provides the necessary structural support for the scaffold.
