Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wind turbines are vulnerable to high winds and extreme weather conditions, such as hurricanes and tsunamis, leading to structural damage and maintenance challenges due to the exposure of mechanical and electrical components to adverse climate conditions, necessitating a system that can withstand extreme winds and facilitate easier servicing.
Innovation Solution
A wind turbine system with a propeller assembly and tubular tower design that positions electrical-mechanical components vertically in the upper tower, incorporating a stiff cylindrical tower with removable segments, a mechanism for remote refueling and maintenance, and integrated solar panels for power generation during low wind conditions, along with a drone system for surveillance and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If electrical-mechanical components are positioned in the hub-nacelle at the top of the tower, then the wind turbine can generate electricity efficiently, but the components are exposed to adverse climate conditions (high winds, hurricanes, tsunamis) causing structural damage and maintenance challenges
Solution Approach 1:
The patent repositions the electrical-mechanical components from the horizontal hub-nacelle at the tower top to a vertical orientation within the tower structure itself. This dimensional reconfiguration places components at different heights along the tower, protecting them from direct exposure to extreme weather while maintaining their functional relationship to the rotor hub through vertical shafts and gears.
2Strength
If the tower structure is strengthened to withstand extreme winds up to 150 mph, then the wind turbine can resist hurricane forces, but the weight and structural complexity of the tower increases
Solution Approach 1:
The patent specifies that the tower is constructed from high-strength materials with a minimum yield strength of 355 MPa, representing a composite or enhanced material approach. This allows the tower to achieve the necessary strength to withstand 150 mph winds while minimizing the weight increase that would result from using traditional materials with higher safety factors.
3Power
If mechanical gears and bearings are used to convert rotor rotation to generator speed, then electricity generation is enabled, but the components are subject to shock loads from extreme weather causing unexplained failures
Solution Approach 1:
The patent positions the electrical-mechanical components including gears and bearings within the protected tower structure rather than in the exposed hub-nacelle. This provides beforehand protection against shock loads from extreme weather events, preventing the unexplained failures that have occurred in conventional designs while maintaining the power conversion function.
4Productivity
If the wind turbine is placed in a permanent location to maximize electricity production, then continuous power generation is achieved, but the location is subject to global warming weather fluctuations including hurricanes and tsunamis
Solution Approach 1:
The patent converts the harmful effect of extreme weather by redesigning the tower and component protection system. The strengthened tower structure and protected component placement transform the previously harmful exposure to hurricanes and tsunamis into a manageable environmental factor, allowing continuous operation even in extreme conditions.
5Reliability
If the tower and components are designed for extreme weather resistance, then durability is improved, but the complexity of the structure and maintenance requirements increase
Solution Approach 1:
The patent divides the tower into segments with different material specifications and structural characteristics. The lower portion uses high-strength materials for weather resistance, while upper portions can be optimized for different functions. This segmentation allows durability under extreme conditions while managing overall structural complexity through modular design.

AI summary
A wind turbine system able to withstand up to 150 mph winds, comprising the electricity generating components moved from the nacelle to the top of the tower, positioned vertically, and comprising: a main-shaft bearing; a gearbox; a brake assembly; a high-speed shaft; a generator; and an electrical control cabinet. The purpose of positioning in the tower is to protect the components from high winds, tornados, etc. and to regulate the rotation of the propellers to make more electricity. The turbine can be easily repaired onsite by removing covers on the upper tower; and with snap in replacement parts. Drone, which are stored in the top horizontal housing, can surveil and protect the turbine and the surrounding area. And, solar panels on the sides and/or cover of the top horizontal housing provide energy to the turbine in low and no wind conditions.
