Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional movable aerodynamic control surfaces are used, then the aircraft can be controlled, but the device complexity and weight increase
Solution Approach 1:
The patent replaces traditional mechanical aerodynamic control surfaces with an electric propulsion system using multiple motors and propellers. The control circuit electronically regulates the speed of each motor to achieve flight control through differential thrust, eliminating the need for mechanical control surfaces and their associated linkages.
Solution Approach 2:
The aircraft is divided into multiple independent propulsion units, each with its own motor and propeller. The control system segments the thrust output by independently controlling each motor's speed, allowing precise control of flight parameters through differential thrust distribution across multiple segments.
2Ease of operation
If traditional movable aerodynamic control surfaces are used, then the aircraft can be controlled, but the weight increases
Solution Approach 1:
The patent replaces heavy mechanical control surfaces with lightweight electric motors and electronic control circuits. The propulsion system uses multiple small motors mounted on the wings, controlled by an electronic circuit that regulates current distribution, significantly reducing the weight compared to traditional control surface mechanisms.
3Adaptability or versatility
If differential thrust control is implemented, then maneuverability improves, but the control system complexity increases
Solution Approach 1:
The control circuit performs multiple functions: it regulates the speed of all motors for forward flight control, creates differential thrust for turning, and can individually control motors for hovering and positioning. This multi-functional approach achieves high maneuverability while keeping the control system relatively simple compared to having separate mechanisms for each control function.
