Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple devices (wind turbine, compressor, heat receiver, turbine, power generator) are arranged in a conventional layout, then each device can operate independently, but the total occupied area becomes large
Solution Approach 1:
The patent transitions from a conventional horizontal arrangement of devices to a vertical arrangement where the wind turbine, compressor, heat receiver, turbine, and power generator are stacked one above another. This dimensional change from 2D to 3D space utilization significantly reduces the total occupied area while maintaining operational independence of each device through separate access pathways and support structures.
2Ease of manufacture
If separate power generators are provided for wind turbine and gas turbine, then each power generation path can be optimized, but equipment costs increase
Solution Approach 1:
The patent merges the power generation functions by providing a single power generator that can receive rotational input from either the wind turbine or the gas turbine (turbine). This consolidation reduces equipment costs by eliminating redundant components while maintaining the adaptability to generate power through either wind or solar thermal pathways, as the shared power generator can be coupled to different prime movers as needed.
3Force
If vertical shaft wind turbine is used, then lateral load on tower is reduced, but rotational speed control becomes more challenging
Solution Approach 1:
The patent incorporates a rotational speed control mechanism that monitors the rotational speed of the wind turbine and adjusts the pitch angle of the blades accordingly. When rotational speed exceeds a predetermined threshold, the control mechanism increases the pitch angle to reduce the aerodynamic force and lower rotational speed. This feedback control system effectively manages rotational speed while maintaining the structural advantages of the vertical shaft configuration.
