Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate direction control power device is used to accurately adjust blade positions according to flowing direction, then directional control accuracy is improved, but device complexity and power consumption increase
Solution Approach 1:
The blade revolution shafts are designed to automatically adjust their positions and orientations in response to fluid flow pressure without requiring external control devices. The blades self-adjust to optimal angles through the natural action of fluid pressure, eliminating the need for separate direction control power devices while maintaining accurate directional control
Solution Approach 2:
The system utilizes feedback from fluid pressure acting on the blades to automatically adjust blade revolution shaft positions. The pressure distribution on the blades provides real-time information about flow direction, enabling the blades to self-correct their orientation to maximize energy capture without external sensors or control systems
2Productivity
If blade areas are increased to capture more fluid energy, then energy generation capacity is improved, but structural stability deteriorates under high fluid pressure
Solution Approach 1:
The blade revolution shafts are designed to dynamically adjust their positions and orientations in response to varying fluid pressures. This dynamic adaptability allows the system to maintain optimal energy capture across different flow conditions while automatically reducing stress concentrations that would otherwise lead to structural failure under high pressure
Solution Approach 2:
The system changes operational parameters (blade revolution phase angles and orientations) in response to fluid pressure conditions. By adjusting these parameters dynamically, the blades can operate at larger effective areas for energy capture while the system automatically adapts to pressure conditions to maintain structural integrity
3Loss of energy
If blades rotate in opposite direction to revolution at 1/2 angular velocity, then backward rotational forces are eliminated, but manufacturing complexity increases
Solution Approach 1:
The invention merges the rotation and revolution motions of the blades into a unified mechanism. By combining these two motions with a fixed phase relationship, the system eliminates backward rotational forces while using a single integrated structure rather than separate control mechanisms, simplifying manufacturing
4Loss of energy
If vertical rotating shaft design is used to reduce friction and noise, then operational efficiency is improved, but adaptability to changing flow directions deteriorates
Solution Approach 1:
The vertical rotating shaft design is enhanced with dynamically adjustable blade revolution shafts that can automatically reorient themselves to track changing flow directions. This maintains the friction and noise advantages of vertical rotation while adding the adaptability of directional tracking through the revolutionary motion of the blades
