Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If solar panels are fixed in predetermined positions to maximize sunlight reception, then power generation efficiency is improved, but land resource utilization deteriorates due to prolonged shading
Solution Approach 1:
The solar panels are mounted on a rotatable support structure that allows them to rotate around a vertical axis. This dynamic configuration enables the panels to change their orientation and position over time, allowing sunlight to reach the ground in different patterns at different times, thus maintaining power generation efficiency while periodically reducing shading impact on land utilization.
Solution Approach 2:
The support structure is designed to rotate the solar panels periodically, creating intermittent shading patterns rather than continuous shading. This periodic movement allows different areas of the ground to receive sunlight at different times, enabling agricultural or cultural activities to proceed while the solar panels maintain optimal power generation positions during their rotation cycles.
2Productivity
If the number of solar panels and sunshine area are increased to enhance power generation capability, then power generation efficiency is improved, but device complexity and cost increase
Solution Approach 1:
The support structure serves multiple functions: it holds the solar panels, provides rotational movement for optimization, and acts as a framework that can accommodate wind-driven modules. This multi-functionality allows the system to achieve enhanced power generation capability through a single integrated structure rather than adding separate complex systems, thus improving productivity while controlling device complexity.
3Productivity
If fixed solar panels are used to receive sunshine, then power generation efficiency is improved, but land resource is wasted due to blocked sunlight
Solution Approach 1:
The solar panels are mounted on a rotatable support structure that allows them to rotate around a vertical axis. This dynamic configuration enables the panels to change their orientation and position over time, allowing sunlight to reach the ground in different patterns at different times, thus maintaining power generation efficiency while periodically reducing shading impact on land utilization.
4Reliability
If power control modules are added to integrate different voltaic specifications and current properties, then power generation reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent removes the power control module component entirely from the system. Instead of adding electronic circuits to manage different voltaic specifications and current properties, the invention relies on the natural compatibility of the wind-driven and solar power generation systems when both drive the same power generator through a common drive shaft, thus achieving power integration without increasing device complexity.

AI summary
A hybrid solar wind power generation device includes a wind-driven module and a solar module drivingly connected with a drive shaft of a power generator. The wind-driven module has a wind-driven blade set drivable by wind power to drive the drive shaft for driving the power generator to generate power. The solar panel set has multiple solar panels arranged at intervals to drive the motor for driving the solar panel and the drive shaft to rotate. Both the wind-driven module and the solar module serve to drive the drive shaft for driving the power generator to generate power. During the process of power generation, the sunlight passes through the hollow sections between the wind-driven blades and the solar panels in rotation and project onto the ground. This improves the shortcoming that the sunlight is blocked from the space under the equipment.
