Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If propeller-like turbines with horizontal rotation axis are used, then electric power can be generated from wind, but the cost becomes extremely expensive and the structure becomes complex
Solution Approach 1:
The patent inverts the conventional horizontal-axis propeller turbine design by adopting a vertical-axis turbine configuration. The wind flows horizontally through a pyramidal or conical chamber containing rotors with vertical vanes, reversing the traditional orientation and simplifying the overall structure while maintaining power generation capability
Solution Approach 2:
The turbine is divided into multiple independent rotors (N rotors) that can rotate independently within the chamber. Each rotor has its own vertical vanes (V vanes), allowing the system to process wind flow through multiple parallel paths, reducing the complexity burden on any single component
2Power
If conventional turbines are used, then power generation is achieved, but they are unable to adequately utilize rapidly varying winds and different wind directions
Solution Approach 1:
The patent employs multiple rotors that can rotate independently and adaptively respond to changing wind conditions. The vertical vanes on each rotor are designed to capture wind from various directions, and the multiple rotors working in parallel allow the system to dynamically adjust to rapidly varying winds without requiring complex control mechanisms
Solution Approach 2:
The pyramidal or conical chamber design with multiple rotors creates a universal structure that can effectively capture wind from different directions and varying speeds. The geometry of the chamber and the arrangement of vertical vanes on rotors enable the system to function efficiently under diverse wind conditions, making it versatile and adaptable
3Power
If conventional turbines are used, then power generation is achieved, but components require replacement to vary power output, increasing cost and maintenance
Solution Approach 1:
The patent achieves variable power output through the dynamic operation of multiple independent rotors. By controlling the rotation speed and operational state of individual rotors, the system can adjust total power output without replacing expensive components. The vertical vanes and rotor design allow flexible modulation of power generation capacity
Solution Approach 2:
The multiple rotors with vertical vanes are designed to self-regulate their operation based on wind conditions. The system inherently adjusts power output through the natural interaction of wind flow with the pyramidal/chamber structure and rotor arrangement, eliminating the need for expensive active control components and frequent replacements
4Power
If conventional turbines are used, then power generation is achieved, but they are particularly noisy
Solution Approach 1:
By inverting to a vertical-axis configuration with horizontal wind flow through the chamber, the patent reduces noise-generating elements. The vertical vanes move more smoothly compared to horizontal propeller blades, and the enclosed chamber structure contains and directs airflow more quietly, significantly reducing operational noise while maintaining power generation
5Power
If conventional turbines are used, then power generation is achieved, but they lack adaptability to different space dimensions
Solution Approach 1:
The patent employs asymmetric pyramidal or conical chamber geometries that can be configured in different orientations and scales. This asymmetric design allows the turbine to adapt to various spatial constraints and installation environments, whether rooftop, ground-mounted, or integrated into existing structures, providing flexibility in dimensional adaptation
