Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If traditional wind turbines mounted on towers are used, then power generation is achieved, but the system requires tall towers and complex control systems, increasing costs and reducing scalability
Solution Approach 1:
The system divides the power generation function into two separate components: an airborne wind energy device that captures wind energy at high altitude, and a ground-based generator that converts the mechanical energy. This segmentation eliminates the need for tall towers and complex control systems at the power generation site, while allowing the airborne component to be relatively simple and lightweight.
Solution Approach 2:
The patent introduces a cable as an intermediary element that transmits mechanical energy from the airborne wind energy device to the ground-based generator. This intermediary allows the separation of the wind capture function (at altitude) from the power generation function (at ground level), resolving the contradiction between power generation capability and system complexity.
2Productivity
If airborne wind energy devices are used to exploit high-altitude winds, then power generation efficiency is improved, but the system requires complex control systems and has intermittent operation due to high minimum wind speed requirements
Solution Approach 1:
The airborne wind energy device is designed to automatically respond to wind conditions without complex active control. The device self-regulates its operation based on ambient wind speeds, allowing it to operate intermittently only when wind conditions are favorable, thereby eliminating the need for complex control systems while maintaining high power generation efficiency during operational periods.
3Power
If the air device operates in high winds, then power generation increases, but loading on the system increases requiring complex control to moderate loading
Solution Approach 1:
The system dynamically adjusts the operational parameters of the airborne wind energy device based on wind conditions. During high wind events, the device automatically reduces its effective loading through passive aerodynamic mechanisms, allowing it to harness high wind energy while protecting the system from excessive forces that would require complex active control systems.
