Solution Overview

Problem

Service technicians in wind farms face difficulties in communication due to the lack of cellular or wireless internet coverage during maintenance and repair of wind turbines.

Innovation Solution

A wireless communication system is established using a base station, wireless bridge, and access points to provide bi-directional data transmission, utilizing Cisco Aironet and Cisco 3500 Series devices to extend communication signals up to 20 miles, ensuring coverage within and around wind turbines, including service roads and adjacent turbines.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If traditional cellular or wireless internet infrastructure is used, then communication coverage is available in populated areas, but coverage is absent in remote wind farm locations

Engineering Contradiction:
Improvecommunication coverage areaVSAvoidcommunication reliability
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The communication system is segmented into multiple distributed access points deployed across individual wind turbines throughout the wind farm. Each access point serves as an independent node that collectively provides comprehensive coverage across the entire wind farm area, resolving the contradiction between coverage area and reliability in remote locations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system extends communication coverage by utilizing the vertical dimension through mounting access points on tall wind turbine structures. This elevates the communication infrastructure above the ground level, enabling signal transmission across the wind farm landscape and overcoming the limitation of traditional ground-based cellular infrastructure in remote areas.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If wireless communication infrastructure is deployed throughout the wind farm, then communication coverage is improved, but system complexity and installation difficulty increase

Engineering Contradiction:
Improvecommunication coverage areaVSAvoidsystem complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The access points are designed as universal, multi-functional units that can be deployed on any wind turbine in the farm. Each unit serves multiple purposes: providing wireless connectivity to technicians, enabling remote monitoring, and supporting maintenance operations. This standardization reduces system complexity despite the distributed deployment across multiple locations.

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

Solution Approach 2:

The wireless communication system is integrated into the existing wind turbine infrastructure, utilizing the turbine's structural components for mounting and power supply. The system leverages available resources at each turbine location, reducing the need for separate infrastructure and simplifying installation and maintenance operations.

Inventive Principle:
Principle #25Self-service
