Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wind turbines, both horizontal and vertical axis, face issues such as bird strikes, high maintenance costs, noise, flicker, ice throws, placement restrictions, and instability at high wind speeds, with vertical axis turbines having lower efficiency and size limitations.
Innovation Solution
The cyclonic aeolian turbine design incorporates a cavity shell that utilizes the Venturi, Bernoulli, and Coanda effects to accelerate wind, create a vortex, and reduce drag, with a yaw system for optimal wind alignment and adjustable features for varying wind conditions, allowing for both vertical and horizontal installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Vertical Axis Wind Turbines are exposed 360 degrees to wind, then they can capture wind from all directions, but only one blade is at optimal angle causing remaining blades to create drag and reducing efficiency
Solution Approach 1:
The cavity shell is pre-configured with asymmetric geometry and airfoil structures that automatically orient the blades to optimal angles relative to incoming wind before the blades even rotate, eliminating the need for reactive adjustment mechanisms
Solution Approach 2:
The cavity shell acts as an intermediary between the wind and the blades, channeling and conditioning the wind flow to approach the blades at optimal angles, thereby mediating the interaction to maximize efficiency while maintaining 360-degree exposure
2Strength
If current VAWT are limited to size restrictions due to cabling and guide wires, then structural support is maintained, but turbine size and power output are constrained
Solution Approach 1:
The design replaces the mechanical support system of guide wires and cabling with a self-contained cavity shell structure that provides structural integrity through its geometric form and aerodynamic loading distribution, eliminating the need for external tensile support elements
Solution Approach 2:
The cavity shell employs curved, aerodynamic surfaces that distribute wind loads evenly throughout the structure, replacing the linear, tension-based support system with a form that naturally resists deformation through its geometry
3Productivity
If Horizontal Wind Turbines place generator high with blades, then wind capture is optimized, but maintenance costs increase
Solution Approach 1:
The design inverts the conventional arrangement by placing the generator and heavy components at the base rather than at the top, reversing the traditional hierarchy to improve maintenance accessibility while maintaining wind capture efficiency through the vertical axis configuration
4Device complexity
If VAWT are inherently unstable at higher wind speed regimes, then simpler structure is maintained, but operational stability deteriorates
Solution Approach 1:
The cavity shell geometry and blade configuration are specifically designed to change their aerodynamic parameters in response to wind speed variations, automatically adjusting the flow characteristics to maintain stability across a wide range of operating conditions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances wind energy harvesting efficiency, reduces maintenance costs, mitigates safety concerns, and allows for larger turbine sizes without guide wires, while being more stable at high wind speeds and reducing noise and flicker issues.
Implementation Method 1
the shell has an intake opening that takes advantage of the Venturi effect to accelerate the wind ingested into the shell, thus increasing the energy of the ingested wind and decreasing the pressure inside the shell, thus creating a suction effect that pulls more wind into the shell
Implementation Method 2
the cavity shell has an airfoil that takes advantage of the Bernoulli effect to contribute to the acceleration of the ingested air and also to increase the ratio of harvested wind
Implementation Method 3
the shell has a substantially circular cross-section to take advantage of the Coanda effect to convert the ingested wind into a vortex that constantly approaches the blades at the optimum angle of attack

AI summary
A wind turbine is provided that has a blade encased into a substantially circular portion of a shell, the shell having an interior surface, an exterior surface, a first end, an opposite second end, and an intake opening between the first and the second end, wherein the first end is closed and wherein the shell has an exhaust opening at or near the second end, wherein wind ingested into the shell through the intake opening is forced to become a vortex having a higher speed than the ingested wind and concentrating the ingested wind substantially near the interior surface of the shell into a spiral air stream traveling toward the exhaust opening, in order to increase an amount of energy harvested by the blade from the ingested wind before the ingested wind, devoid of the amount of energy harvested, exits the shell through the exhaust opening.
