Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional vector thrust mechanisms are used to redirect working fluid, then vertical flight capability is achieved, but device complexity increases due to rotating or tilting entire vehicle and engine
Solution Approach 1:
The propulsion system is divided into separate functional modules: a fixed power module that generates thrust, and a独立的向量推力机构 that redirects the working fluid. This segmentation allows the vehicle body to remain stationary while only the fluid redirection components move, significantly reducing the complexity of rotating or tilting the entire vehicle and engine assembly.
Solution Approach 2:
The vector thrust mechanism is extracted as a separate component from the power module. By taking out the fluid redirection function and making it independent, the system achieves vertical flight capability without requiring the entire vehicle and engine to rotate or tilt, thereby reducing overall device complexity while maintaining adaptability.
2Ease of manufacture
If modular design is implemented for propulsion system, then ease of manufacture and maintenance improves, but device complexity may increase due to multiple detachable components
Solution Approach 1:
The propulsion system is segmented into standardized modular components including the power module, vector thrust mechanism, and control systems. Each module is designed with standardized interfaces that simplify assembly and maintenance operations, making the system easier to manufacture while the modular architecture itself manages the complexity of multiple detachable components through systematic design.
Solution Approach 2:
The modular components are designed with universal interfaces and standardized connection protocols that allow the same modules to be reused across different vehicle configurations and applications. This universality reduces the overall complexity by creating a library of interchangeable parts rather than requiring unique components for each assembly.
3Object-affected harmful factors
If electric power sources are used for propulsion, then environmental friendliness improves, but energy density and power output may be limited compared to combustion engines
Solution Approach 1:
The system incorporates hydraulic or pneumatic assistance mechanisms that work in conjunction with the electric power source. These fluid-based systems can provide power multiplication and torque amplification, allowing electric motors to achieve power outputs comparable to combustion engines while maintaining the environmental benefits of electric propulsion.
Solution Approach 2:
The system employs variable parameter control including adjustable vector thrust angles, variable speed electric motors, and dynamic power distribution that optimize performance across different flight conditions. By changing operational parameters rather than relying on a single fixed-power engine, the electric propulsion system achieves sufficient power output while maintaining environmental friendliness.

Implementation Method 1
electrical energy is the source with the greatest adaptation among users and developers, which also includes generation of electrical energy through processing of elements like hydrogen for charging a battery system or supplying direct energy to electrical motors
Implementation Method 2
thrust is usually generated through the application of Newton's third law of action and reaction where a working fluid, is accelerated and the reaction to this acceleration produces a resulting force that is used to move the vehicle
