Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a standard Savonius turbine is used, then the structure is simple, but negative resistance occurs on the convex side limiting maximum rotation
Solution Approach 1:
The turbine system is divided into two independent rotational components: a secondary axle that rotates around its own axis, and a primary main axis that rotates around the vertical centerline. This segmentation allows the rotor to be positioned optimally relative to wind direction while maintaining structural simplicity.
Solution Approach 2:
The invention adds a second rotational dimension by introducing the secondary axle that can rotate independently around its axis while the main axis rotates vertically. This dimensional addition enables the rotor to achieve ideal positioning angles (15-45 degrees) relative to wind direction, eliminating negative resistance on the convex side.
2Device complexity
If the turbine rotor is fixed in position, then the structure is simple, but it cannot avoid negative resistance from convex side wind impact
Solution Approach 1:
The rotor is made dynamically adjustable through the secondary axle mechanism that can rotate around its axis to position the rotor at optimal angles (15-45 degrees) relative to the wind direction. This dynamic positioning eliminates the harmful negative resistance effect on the convex side while maintaining operational simplicity.
Solution Approach 2:
The invention changes the positional parameter of the rotor by introducing a variable rotation angle on the secondary axle. By adjusting the rotor's angular position relative to the wind direction within the 15-45 degree range, the system optimizes wind capture and eliminates negative resistance without complex control systems.
3Device complexity
If wind current is not redirected, then the turbine structure is simple, but wind energy utilization is insufficient
Solution Approach 1:
The wind router acts as an intermediary element between the wind current and the rotor. It redirects and channels the wind flow to strike the rotor at optimal angles, maximizing energy transfer and utilization while keeping the overall structure relatively simple.
Solution Approach 2:
The wind router performs preliminary action by pre-positioning and directing the wind current before it reaches the rotor. This preliminary flow conditioning ensures that wind energy is optimally delivered to the rotor surface, enhancing energy utilization without requiring complex active control systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The wind router effectively directs wind currents to maximize thrust and energy capture, overcoming the limitations of negative resistance and enhancing overall wind energy utilization.
Implementation Method 1
a part of the wind current from the convex side of the blade is directed to the concave side, which causes a pressure that increases the wind utilization
Implementation Method 2
the effect of the thrust, that is, the pulling of the rotor, directly behind the negative side of the rotor is achieved
Implementation Method 3
positioning it on a secondary axle which, in addition to rotating itself around its axis, also turns around the main axis on which wind routers are located
