Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a water turbine generator is installed in natural marine current to generate electricity, then power generation is possible using continuous marine current, but the speed of marine currents is not uniform and flow direction frequently changes, making it difficult to ensure structural stability and control power generation reliably
Solution Approach 1:
The patent applies dynamics by making the turbine shaft and blades movable and adjustable rather than fixed. The turbine shaft can rotate to face the incoming marine current, and the blades can be adjusted in angle and position to optimize performance under varying flow conditions, allowing the system to adapt to non-uniform current speeds and changing flow directions while maintaining structural stability and reliable power generation control
Solution Approach 2:
The patent changes physical parameters of the turbine system dynamically - adjusting the orientation angle of the turbine shaft, modifying the pitch angle of the blades, and varying the rotational speed to match the instantaneous marine current conditions. These parameter adjustments enable the system to maintain optimal power generation efficiency despite variations in current speed and direction
2Power
If tidal power generation is used with a reservoir to generate electricity from tidal range, then power can be generated using tidal difference, but it requires artificial seawalls and reservoirs which increases device complexity and installation cost
Solution Approach 1:
The patent extracts and removes the reservoir and artificial seawall components from the traditional tidal power generation system. By eliminating these complex structures, the invention simplifies the overall system while still achieving power generation from tidal range, reducing both device complexity and installation costs
Solution Approach 2:
The patent employs self-service by using the natural marine current flow itself to drive the turbine without requiring artificial containment structures. The system leverages the existing environmental resource (marine current) directly, eliminating the need for additional infrastructure like reservoirs and seawalls that would otherwise be required to create the necessary flow conditions
