Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wind power generation systems are inefficient due to large size, high wind speed requirements, noise pollution, and inability to harness energy from low wind velocities, while surplus hot air and gas are often wasted, and current technologies fail to integrate multiple energy sources effectively.
Innovation Solution
A rooftop-mounted apparatus that combines solar energy, wind power, and convection effects using a cyclonic machine with vertical axis wind flow, multiple convectors, and photovoltaic modules to generate electric power, allowing energy generation from lower wind speeds and utilizing surplus hot air, with a design that converts horizontal wind flow into vertical energy and directs it to propeller blades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional wind turbines with large blades are used to generate sufficient power, then power generation capability is improved, but device size becomes excessively large and noise increases
Solution Approach 1:
The patent combines multiple energy sources (wind, solar, convection) into a single integrated power generation system. The hybrid design merges a vertical axis wind turbine with solar panels and convection-driven turbines, allowing the system to generate electricity from multiple sources simultaneously, thereby achieving sufficient power output without requiring excessively large wind turbine blades
Solution Approach 2:
The integrated system performs multiple functions within a single structure: it generates power from wind through the vertical axis turbine, captures solar energy through photovoltaic panels, and utilizes convection currents through additional turbines. This multi-functionality allows the system to maintain compact size while achieving reliable power generation across varying environmental conditions
2Adaptability or versatility
If conventional wind turbines operate at low wind velocities, then adaptability is improved, but power generation becomes insufficient
Solution Approach 1:
The system combines wind power generation with solar power generation and convection-driven power generation. When wind velocity is low, the solar panels and convection turbines compensate to maintain sufficient power output, thereby achieving both adaptability to varying wind conditions and consistent power generation
3Ease of operation
If surplus hot air is discharged into the atmosphere, then simplicity of operation is maintained, but energy waste increases
Solution Approach 1:
The system converts the previously wasted surplus hot air into a useful energy source. The convection-driven turbines capture the kinetic energy and thermal energy of the rising hot air that would otherwise be discharged, transforming this waste stream into electricity generation while maintaining simple operation through passive convection forces

AI summary
The system and method for a green integrated electric power plant mounted on rooftops, includes platform on which installed low body and upper body with gap. There are no rotatable parts for generating electric power except the propeller of generator which is affected by three air flows. The generator with propeller placed inside of upper body vertically. Low body has inside tube and spirals. Also low body has a few windows. Each window supplied by tangential plate for creating confined vortex. Thus one wind flow acting through low body directly on propeller, second air flow move warm air flow from source of warm air such as laundry or boiler room of building through conduit, inner tube and multiple Venturi tubes also act as a propeller. Third wind air flow moves perpendicular to vertical axes of generator and goes through gap between low body and upper body directly on propeller.
