Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the wind rotor diameter is increased to generate more power, then the power output is improved, but the main shaft diameter becomes too big and difficult to manufacture
Solution Approach 1:
The patent divides the traditional single main shaft structure into multiple independent support columns. Each column supports a portion of the wind rotor, eliminating the need for a single large-diameter main shaft. This segmentation allows for easier manufacturing of individual columns while maintaining the structural integrity and power generation capability of the overall system.
2Power
If the wind rotor diameter is increased, then the power output is improved, but the tower height and strength requirements increase
Solution Approach 1:
The tower structure is segmented into multiple independent support columns rather than a single tall tower. This distributes the mechanical loads and reduces the strength requirements for each individual column, while collectively supporting the larger wind rotor diameter needed for higher power output.
3Device complexity
If the blade rotation angle is fixed, then the device complexity is reduced, but the aerodynamic efficiency decreases due to varying torque
Solution Approach 1:
The patent implements dynamic blade angle adjustment through a servo mechanism that automatically modifies the blade rotation angle in response to varying wind conditions and rotor position. This dynamic adaptation maximizes aerodynamic efficiency by optimizing the angle of attack, thereby reducing energy losses while managing the added device complexity through automated control.
4Productivity
If the blade width is increased to achieve desirable wind rotor radius ratio, then the aerodynamic performance is improved, but the manufacturing and transportation difficulty increases
Solution Approach 1:
The patent segments the wide blade structure into multiple narrower blade sections. Each section maintains the necessary aerodynamic properties while being easier to manufacture and transport. The segmented sections are then assembled to form the complete wide-blade configuration, achieving the desirable wind rotor radius ratio without the manufacturing and transportation challenges of a single wide blade.
