Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the aerial vehicle is used for agricultural work without posture control, then the device complexity is reduced, but the work precision and reliability deteriorate
Solution Approach 1:
A posture control mechanism is introduced as an intermediary component between the aerial vehicle and the work apparatus. This mechanism includes actuators and sensors that actively adjust the orientation and position of the work apparatus, ensuring precise work performance while isolating the complexity from the core aerial vehicle system.
Solution Approach 2:
The system employs dynamic posture control where the work apparatus can actively adjust its orientation in real-time based on flight conditions and terrain requirements. This dynamic adjustment capability allows the system to maintain optimal work posture during flight, improving precision without requiring the entire aerial vehicle to be overly complex.
2Reliability
If the connection between aerial vehicle and work apparatus is maintained during flight, then the system stability is improved, but the risk of crash increases due to uncontrollable posture
Solution Approach 1:
A buffer mechanism is incorporated into the connection system between the aerial vehicle and work apparatus. This buffer mechanism includes shock-absorbing elements that can cushion impacts and reduce the transmission of sudden forces, thereby preventing crashes while maintaining connection stability during normal operation.
Solution Approach 2:
The system implements feedback control through sensors that monitor the posture and connection status between the aerial vehicle and work apparatus. This feedback information is used by the control system to continuously adjust the connection mechanism, maintaining stable connection while preventing crash conditions by detecting and responding to adverse situations in real-time.
3Manufacturing precision
If the work apparatus is pressed against the ground surface without inclination control, then the ease of operation is improved, but the work precision on inclined surfaces deteriorates
Solution Approach 1:
An inclination detection system with sensors is integrated into the work apparatus to detect the slope angle and orientation of the ground surface. This feedback information is transmitted to the control system, which automatically adjusts the pressing force and orientation of the work apparatus to maintain optimal contact with the ground surface, ensuring precise work on inclined surfaces without requiring manual intervention.
Solution Approach 2:
The work apparatus is equipped with self-adjusting mechanisms that automatically adapt to ground inclination based on sensor input. The system performs self-correction of its posture and pressing force, eliminating the need for constant manual adjustment by the operator while maintaining high work precision on varied terrain.
