Solution Overview

Problem

Current vertical axis wind turbines (VAWTs) and tower fans cannot efficiently generate power from straight flowing wind and simultaneously propel it in reverse, lacking the efficiency and reversibility of the proposed multi-axis designs with multiple planet rotors and paired airfoils.

Innovation Solution

A multi-axis turntable, wind turbine, and tower fan system featuring multiple planet rotors rotating around a stationary sun rotor with paired planet and sun airfoils, where planet airfoils maintain a fixed orientation to face against or toward the wind, while sun airfoils rotate radially to optimize power generation and propulsion by alternating as wind shields.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional vertical axis wind turbine uses a single rotating rotor with airfoils, then the structure is simple, but it cannot efficiently generate power from straight flowing wind and cannot be reversed to propel wind

Engineering Contradiction:
Improvereversibility between power generation and wind propulsionVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The single rotor is segmented into multiple planet rotors that rotate around a stationary sun rotor. Each planet rotor carries airfoils, and the segmented configuration enables the system to function as both a wind turbine and a tower fan by controlling the rotation direction of planet rotors relative to the stationary sun rotor

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The multi-axle turntable structure with planet rotors and stationary sun rotor serves dual functions: generating power from wind when planet rotors rotate one direction, and propelling wind when rotated in reverse. The same mechanical structure achieves both functions by changing rotation direction

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

Solution Approach 1:

The airfoil system is segmented into planet airfoils mounted on rotating planet rotors and stationary sun airfoils mounted on the fixed sun rotor. This segmentation allows planet airfoils to maintain optimal orientation by rotating with their carriers while sun airfoils provide stationary wind shielding

Inventive Principle:

Solution Approach 2:

The planet airfoils are mounted on rotating planet rotors that carry them through circular paths, allowing the airfoils to dynamically maintain optimal orientation relative to the wind direction throughout their rotation, maximizing power generation efficiency

Inventive Principle:

Solution Approach 1:

Multiple planet rotors are merged into a single integrated multi-axle turntable mechanism where all planet rotors rotate around the stationary sun rotor on the same plane.

AI summary

A Multi Axes Wind Turbine of the present invention comprises a multi axes turntable assembly in rotations with a mounted assembly of pairs of planet and sun airfoils for generating a net of substantial powers from generally straight flowing applied wind or airflow. Planet airfoils, been in a fixed rotational orientation relative to and in rotation around a stationary sun rotor, are always facing against applied wind. Different from planet airfoils, sun airfoils are in radial alignment to and in rotation around the sun rotor, and are rotated by applied wind from any direction. In combination, paired planet and sun airfoils alternate as wind shields in rotations around a stationary sun rotor to greatly enhance powers generated while greatly reduce powers lost. A Multi Axes Wind Turbine operated in reverse is a multi-axes tower fan to propel a substantial volume of generally straight flowing wind or airflow.
