Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a wind collection pipe structure with guide walls is added around a vertical shaft wind power turbine to concentrate wind direction and increase wind speed, then wind power generation efficiency is improved, but resistance is considerably generated when wind directly contacts drag type blades, making it difficult to effectively generate wind power at high speeds
Solution Approach 1:
The patent introduces an intermediary flow guidance structure that mediates between the wind collection pipe and the drag type blades. The guide walls are designed to direct wind flow along a predetermined path that avoids direct contact between wind and blades at high speeds, while still maintaining effective wind concentration for power generation. This intermediary structure resolves the contradiction by controlling wind-blade interaction.
Solution Approach 2:
The patent changes the operational parameters of the wind turbine system by using drag type blades that can adjust their angle of attack and positioning. The blades are designed to operate at optimized angles that maximize power generation at low speeds while minimizing resistance at high speeds. This parameter adjustment allows the system to adapt to varying wind conditions and resolve the resistance issue.
2Reliability
If drag type wind power blades are used in a vertical shaft wind power turbine with a wind collection pipe, then the turbine can be started effectively, but the configuration acts as resistance when wind speed is high, making it difficult to consistently generate wind power
Solution Approach 1:
The patent implements dynamic control of the drag type blades, allowing them to adjust their position and angle based on wind speed conditions. At low speeds during startup, the blades are positioned to maximize drag and facilitate starting. At high speeds, the blades adjust to reduce resistance while maintaining power generation. This dynamic adjustment resolves the contradiction between reliable starting and consistent power generation.
Solution Approach 2:
The patent employs periodic adjustment mechanisms that modulate the blade positions and angles in response to varying wind conditions. The system periodically adjusts blade parameters to optimize performance across different operational phases, ensuring reliable startup followed by efficient continuous power generation. This periodic control strategy addresses the inconsistency in power generation at high speeds.
