Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a power line is connected between the airship and ground system to transmit power, then power transmission is achieved, but the system complexity increases due to power line installation and connection requirements
Solution Approach 1:
The patent replaces the mechanical power line connection system with an optical transmission system using lasers. The power generation unit converts mechanical energy from wind turbines directly into laser beams for wireless power transmission to the ground, eliminating the need for physical power lines and their associated connection complexity
Solution Approach 2:
The patent introduces laser beams as an intermediary medium to transfer energy between the airship and ground. Instead of direct electrical connection through power lines, the system uses optical energy as a mediator to bridge the gap between airborne power generation and ground-based power reception
2Power
If a winch system is used to lower the flight vehicle to the ground for power transmission, then power transfer is enabled, but additional costs and accident risks increase
Solution Approach 1:
The patent replaces the mechanical winch-based power transfer system with an optical laser transmission system. This substitution eliminates the need for mechanical contact and physical lowering of the flight vehicle, thereby removing the associated safety risks and additional cost requirements
Solution Approach 2:
The patent extracts and removes the winch system and its associated mechanical components from the power transfer process. By taking out this hazardous mechanical subsystem, the invention achieves power transfer without the risks of mechanical failure, entanglement, or collision that accompany winch operations
3Power
If multiple power generation devices are embedded in the airship to increase floating power, then power generation capacity increases, but the weight and volume of the airship increase, leading to higher costs
Solution Approach 1:
The patent transitions from horizontal expansion (adding more devices within the airship) to vertical utilization (deploying wind turbines in the three-dimensional space around the airship). This allows the airship to harness wind energy from multiple directions and altitudes without increasing its own weight, as the turbines are positioned externally in the surrounding air space
Solution Approach 2:
The patent creates a multi-functional system where the airship serves both as a platform for power generation and as a mobile positioning system. The wind turbines can be deployed and repositioned dynamically to optimize power capture from different wind directions, making the system adaptable to varying environmental conditions without requiring additional fixed infrastructure
