Solution Overview

Problem

The challenge of supporting large wind turbine blades during post-moulding operations is complicated by varying cross-sections, leading to difficulties in accessing all areas, increased safety hazards from overhead cranes, and prolonged manufacturing times due to scaffold assembly and disassembly, especially with larger blades.

Innovation Solution

A tool with a base and support structure that adjusts to fit the blade's outer surface, allowing secure support and adjustable height, reducing the need for overhead cranes and simplifying scaffold use, while enabling easier access and safer operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If scaffolds are assembled to support and secure the wind turbine blade during post-moulding operations, then accessibility to the blade is improved, but the manufacturing time increases due to assembly and disassembly operations

Engineering Contradiction:
Improveaccessibility to bladeVSAvoidmanufacturing time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The support structure is pre-configured with adjustable height mechanisms and positioning features that allow it to be quickly deployed and adjusted to the required blade position before operations begin, eliminating time-consuming assembly procedures

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The support structure incorporates adjustable height components that can be dynamically modified during operations to accommodate different blade positions and operational requirements, replacing the need for complete scaffold assembly and disassembly

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the wind turbine blade is rotated about its longitudinal axis to facilitate access to different areas, then accessibility to all blade areas is improved, but safety hazards increase due to overhead crane operations

Engineering Contradiction:
Improveaccess to blade areasVSAvoidsafety hazards
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The support structure serves as an intermediary device that holds the blade in safe, accessible positions without requiring overhead cranes to suspend and rotate the blade, thereby eliminating the safety hazards associated with crane operations while maintaining operational accessibility

Inventive Principle:
Principle #24Intermediary (Mediator)

3Power

If larger wind turbine blades are manufactured to increase capacity, then energy production is improved, but the complexity of support operations increases

Engineering Contradiction:
Improveenergy productionVSAvoidsupport operations complexity
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

The support structure is designed as a universal system that can accommodate blades of various sizes through adjustable height and positioning mechanisms, eliminating the need for different support systems for different blade lengths and reducing operational complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)
