Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the size of a single wind turbine is increased to increase electricity generation, then the electricity generation capacity is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The invention divides the wind power generation system into multiple separate wind turbines (at least three) arranged in parallel, each with its own generator. Instead of using one large turbine, the system segments the power generation function across multiple smaller turbines working together, thereby achieving high electricity generation capacity while maintaining manageable turbine sizes for easier manufacturing and operation.
2Productivity
If a larger cylindrical wind tunnel body is used to accommodate bigger wind turbines, then the electricity generation is improved, but the device complexity and space requirements increase
Solution Approach 1:
The invention eliminates the need for a single large cylindrical wind tunnel body by segmenting the wind flow path. Multiple smaller wind tunnels or flow guides are provided, each corresponding to an individual wind turbine. This allows the wind flow to be distributed across multiple channels, achieving high power generation without requiring one massive enclosed structure.
3Productivity
If multiple wind turbines are arranged to increase electricity generation, then the productivity is improved, but the device complexity increases
Solution Approach 1:
The invention merges multiple wind turbines and their corresponding generators into a single integrated power generation unit that operates together. The shafts of multiple wind turbines are connected to generators in a unified manner, allowing the system to function as one coordinated entity. This merging approach increases electricity generation capacity while managing complexity through integrated design rather than separate independent systems.
