Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hybrid photovoltaic systems that combine solar and wind energy face inefficiencies due to the incompatibility of wing orientation for optimal sunlight and wind direction, and are environmentally criticized for their spinning motion, which poses risks to birds and generates noise.
Innovation Solution
A photovoltaic wing with a rectangular-like surface, utilizing harmonic pendulous movement caused by wind, featuring a tilting axis of 20° to 45° with a return mechanism and electricity-generating mechanism, designed to optimize energy capture from both solar and wind sources without the need for spinning motion, made from high-strength, low-specific-gravity materials.

Engineering Contradiction Analysis
1Productivity
If photovoltaic panels are integrated with windmills by arrangement directly on the working surface of the wings, then the device can generate electricity from both solar and wind energy, but the wing orientation cannot be optimized for both sunlight and wind direction simultaneously
Solution Approach 1:
The wing is designed to be movable and adjustable, allowing it to change its orientation dynamically. The wing can be tilted and rotated to optimize its position for both sunlight capture and wind direction, resolving the contradiction between fixed orientation and multi-directional optimization. This dynamic adjustment capability enables the photovoltaic panels to maintain optimal angles for energy generation under varying environmental conditions.
Solution Approach 2:
The windmill structure is divided into separate functional components: the wing carrying photovoltaic panels, the rotor blades for wind capture, and the adjustment mechanism. This segmentation allows independent optimization of each component - the wing can be positioned for solar exposure while the rotor blades capture wind energy, enabling both functions to operate at peak efficiency simultaneously.

If traditional spinning windmills are used for wind energy generation, then electricity can be generated from wind, but the spinning motion poses environmental risks to birds and generates noise
Solution Approach 1:
The traditional continuous spinning rotor is replaced with an oscillating wing mechanism that moves back and forth in a controlled manner. This substitution of mechanical motion type reduces the harmful effects - the oscillating motion is less disruptive to birds compared to high-speed rotation, and the mechanism operates more quietly. The wing still effectively captures wind energy through its reciprocating motion while minimizing environmental harm.
Solution Approach 2:
Instead of continuous spinning, the wind energy conversion mechanism uses periodic oscillating motion of the wing. The wing moves back and forth in a controlled periodic cycle, which maintains energy generation effectiveness while reducing the continuous rotational forces that harm birds and create noise. This periodic action transforms the harmful continuous rotation into a gentler, more environmentally friendly reciprocating motion.
