Solution Overview

Problem

The transportation and assembly of power control modules (PCMs) and tower sections in wind turbines are cumbersome and costly due to their large size and weight, particularly in offshore applications, where traditional mounting methods are time-consuming and inefficient.

Innovation Solution

A method involving a temporary support device to assemble and connect pre-fabricated power control modules with tower sections, reducing crane actions and enabling more efficient transportation and assembly by suspending the PCM within the tower section using suspension bars or internal supports, and incorporating elastic means for stability and vibration absorption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the PCM is mounted on a foundation at the erection site and then the tower is mounted around it, then the installation can be completed, but the procedure becomes troublesome and time-consuming

Engineering Contradiction:
Improveinstallation speedVSAvoidinstallation complexity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The power control module is pre-mounted on a temporary support device at the manufacturing site before the tower section is assembled around it. This preliminary preparation allows the tower and PCM to be transported as integrated units to offshore locations, eliminating time-consuming on-site mounting operations and significantly improving installation productivity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The tower section is designed to be assembled around the pre-mounted PCM, creating a nested configuration where the PCM is positioned within the tower structure. This nesting approach allows both components to be transported together and simplifies the installation process by eliminating separate mounting operations

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of manufacture

If the PCM and tower are transported separately and assembled at the erection site, then the components can be installed, but the transportation and assembly become cumbersome and costly

Engineering Contradiction:
Improvetransportation efficiencyVSAvoidassembly time
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The PCM and tower section are merged into a single integrated unit by pre-mounting the PCM on a temporary support device that becomes part of the tower structure. This combination allows both components to be transported together on a single vessel, reducing transportation costs and improving efficiency while maintaining assembly capability

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If traditional mounting methods are used at offshore locations, then the installation can be completed, but the process becomes time-consuming and inefficient

Engineering Contradiction:
Improveinstallation efficiencyVSAvoidcrane time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The PCM is pre-positioned on a temporary support device at the manufacturing site before transport, allowing for rapid installation at offshore locations. This preliminary action eliminates the need for time-consuming on-site mounting operations and reduces crane time significantly

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

A temporary support device serves as an intermediary component that facilitates the pre-mounting of the PCM and its integration with the tower section. This intermediary structure enables efficient transport and installation while being removed after the PCM is securely connected to the tower

Inventive Principle:
Principle #24Intermediary (Mediator)
