Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a three-blade wind turbine generator is selected for power generation, then power generation efficiency in high wind-speed environment is improved, but power generation efficiency in low wind-speed environment deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the blade configuration changeable rather than fixed. The wind turbine generator can dynamically switch between three-blade and six-blade configurations based on real-time wind speed conditions. This is achieved through a blade assembly that can be adjusted between different blade numbers, allowing the system to adapt its structure to match operating conditions and maintain high efficiency across varying wind speeds.

3Device complexity
If the blade number is fixed, then device complexity is reduced, but the ability to maintain high-efficiency power generation across varying wind conditions deteriorates
Solution Approach 1:
The patent applies the segmentation principle by dividing the blade assembly into separable components that can be independently positioned. The blade assembly includes a blade root and multiple blades that can be selectively arranged around the rotor shaft. This segmentation allows the system to configure different numbers of blades (three or six) by positioning individual blades at specific angular intervals, enabling efficient power generation across varying wind conditions while maintaining manageable structural complexity.
