Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If traditional horizontal-axis wind turbines with long rotor blades are used, then wind energy conversion capability is improved, but manufacturing cost and difficulty increase significantly
Solution Approach 1:
The wind turbine rotor is divided into multiple independent panels (first panel, second panel, third panel) that can be manufactured separately and assembled together. Each panel has specific dimensional relationships (second length = half of first length, third length = half of first length; second height = one-third of first height, third height = one-third of first height) allowing modular construction that reduces manufacturing complexity and cost while maintaining effective wind energy conversion area.
2Power
If traditional horizontal-axis wind turbines with long rotor blades are used, then wind energy conversion capability is improved, but sensitivity to strong winds and harsh weather increases
Solution Approach 1:
By segmenting the rotor into multiple smaller panels connected by bearing mechanisms, the system reduces the leverage effect and structural stress experienced by long single-piece blades in strong winds. The segmented design allows each panel to independently respond to wind loads, improving overall reliability and reducing sensitivity to harsh weather conditions.
Solution Approach 2:
The bearing mechanisms connecting the panels allow for dynamic movement and adjustment, enabling the rotor to adapt to varying wind conditions. This dynamic capability reduces stress concentration and improves the system's ability to withstand strong winds and harsh weather while maintaining energy conversion efficiency.
3Power
If traditional horizontal-axis wind turbines are installed, then wind energy conversion is achieved, but initial installation expenses increase due to large and heavy equipment requirements
Solution Approach 1:
The segmented panel design allows the wind turbine to be constructed from smaller, lighter components that can be transported and installed with smaller, less expensive equipment. The modular nature of the panels and their connection mechanisms reduces the need for large cranes and heavy installation machinery, thereby reducing initial installation expenses.
4Power
If traditional horizontal-axis wind turbines are installed, then wind energy conversion is achieved, but environmental disruption increases due to large equipment requirements
Solution Approach 1:
The segmented design enables installation with smaller equipment that causes less environmental disruption. The smaller components require smaller access roads, less ground disturbance, and cause temporary disruption to fewer people and the environment during the installation process.

AI summary
A self-excited wind power system with at least one self-excited panel, each arranged to create periodic motion in response to wind velocity, and a support tower. The self-excited panel is segmented, with at least three segments: a first segment forming a master segment, a second segment, and a third segment defining a tail segment. The first segment of the self-excited panel has a first length and a first height, the second segment has a second length half the length of the first segment and a second height one-third the height of the first segment, and the third segment has a third length half the length of the first segment and a third height one-third the height of the first segment. Furthermore, the second and third segments are connected to the proximal and distal ends of the first segment via a bearing mechanism.
