Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If horizontal turbine blades are used in wind capturing systems, then the system can capture wind energy, but the transmission mechanism increases device complexity and reduces energy conversion efficiency
Solution Approach 1:
The patent inverts the conventional horizontal blade orientation by using vertical turbine blades that rotate around a horizontal axis. This inversion eliminates the need for complex internal transmission mechanisms while fully utilizing the wind's kinetic energy, directly resolving the contradiction between energy conversion efficiency and device complexity
Solution Approach 2:
The patent extracts and removes the problematic internal transmission mechanism from the wind turbine system. By using vertical blades that directly drive the generator without intermediate transmission components, the design simplifies the system while maintaining or improving energy conversion efficiency
2Power
If internal transmission mechanism is added to increase rotor speed, then generator can produce sufficient electrical energy, but not all wind force is utilized
Solution Approach 1:
By inverting the blade orientation to vertical, the system allows the wind to directly drive the rotor without needing speed-increasing transmission mechanisms. The vertical blades capture and convert wind force more efficiently, producing sufficient electrical energy while utilizing nearly all available wind force
3Speed
If deflector narrows the flow passage, then air flow is accelerated and rotor speed increases, but housing design becomes more complex
Solution Approach 1:
The patent employs asymmetric deflector elements within the housing that strategically narrow the flow passage to accelerate air flow. The asymmetric design of deflectors creates targeted flow acceleration zones that increase rotor speed while maintaining a relatively simple overall housing structure
