Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If large wind turbines are used to generate more power, then power generation capacity is improved, but transportation distance increases causing energy loss
Solution Approach 1:
The invention divides a single large wind turbine into multiple smaller wind turbines arranged in a modular configuration. Each turbine operates independently but contributes to the total power generation, allowing energy to be generated closer to consumption points and reducing transportation losses while maintaining overall power capacity.
Solution Approach 2:
The invention transitions from a single large turbine (one-dimensional power generation) to a multi-turbine array system (three-dimensional spatial distribution). This dimensional expansion allows power to be generated at multiple locations simultaneously, reducing the need for long-distance energy transmission.
2Object-affected harmful factors
If smaller biomorphic wind turbines are used to reduce impact on human life, then acceptability is improved, but power generation capacity decreases
Solution Approach 1:
The system segments power generation into multiple small turbines instead of one large turbine. This segmentation maintains the biomorphic design benefits (reduced visual and physical impact) while achieving comparable total power output through the cumulative effect of multiple units.
Solution Approach 2:
The invention combines multiple small biomorphic turbines into a coordinated system where their individual power outputs aggregate to meet overall energy needs. The turbines work together as a unified power generation system while retaining the aesthetic and environmental benefits of small-scale design.
3Object-affected harmful factors
If multiple small wind turbines are arranged in a biomorphic configuration, then acceptability is improved, but airflow strength at turbine level decreases
Solution Approach 1:
The tapering structure is positioned upstream of the turbines to pre-condition and accelerate the airflow before it reaches the rotor blades. This preliminary action ensures that even small biomorphic turbines receive sufficient wind speed for effective power generation.
Solution Approach 2:
The tapering structure acts as an intermediary element between the free stream wind and the turbine rotors. It modifies the wind flow characteristics, concentrating and accelerating the airflow to enhance turbine performance without requiring larger turbine dimensions.
