Solution Overview

Problem

The increasing size of wind turbines leads to greater relative movement of components during installation, posing challenges in merging them during lifting and installation processes.

Innovation Solution

An assembly system with elongated connection elements, such as ropes or wires, is used to synchronize the movement of wind turbine components, guided by assembly assisting elements with actuators and storage devices, allowing for stable connection through crosswise arrangement and controlled tension.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If the size of wind turbines is increased, then the power generation capacity is improved, but the relative movement of components during installation increases

Engineering Contradiction:
Improvepower generation capacityVSAvoidrelative movement of components
Core Design Contradiction:
PowerVSStability of the object's composition

Solution Approach 1:

The patent introduces assembly assisting elements including guiding elements and elongated connection elements as intermediaries between wind turbine components during installation. These elements mediate the connection and coordination between components, reducing relative movement while allowing the turbine size to increase for greater power generation capacity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent applies preliminary action by pre-assembling blade root sections with hub sections using the assembly system before final installation. The guiding elements and connection elements are prepared and positioned in advance, allowing components to be brought together with reduced relative movement even as turbine dimensions increase.

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If traditional assembly methods are used without assembly assisting elements, then the device complexity is low, but the difficulty of merging components increases

Engineering Contradiction:
Improveassembly system complexityVSAvoidease of merging components
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The assembly assisting elements serve as intermediaries that facilitate the merging of components. The guiding elements provide directional guidance while elongated connection elements maintain coordination between components, making the assembly process easier despite the added complexity of these assisting elements.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the assembly system into distinct functional elements: guiding elements for directional control and elongated connection elements for coordination. This segmentation allows each element to perform its specific function, improving ease of operation while keeping the overall device complexity manageable through modular design.

Inventive Principle:
Principle #1Segmentation
