Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If propeller status monitoring is implemented using sensors and wireless communication, then flight safety is improved, but device complexity increases
Solution Approach 1:
The sensor unit is integrated into the propeller structure itself, allowing the propeller to simultaneously perform its primary function of generating thrust and the secondary function of monitoring its own status through embedded sensors. This multi-functionality reduces the need for separate monitoring systems and decreases overall device complexity.
Solution Approach 2:
The sensor unit is nested within the propeller structure, with sensors embedded in the propeller blades. This nesting approach allows the monitoring system to be incorporated into the existing propeller design without requiring additional external components, thereby minimizing the increase in device complexity while maintaining improved flight safety through continuous propeller status monitoring.
2Reliability
If real-time propeller status monitoring is implemented, then collision accidents are prevented, but power consumption increases
Solution Approach 1:
The system monitors propeller status at periodic intervals rather than continuously, with the control unit checking sensor data at specific moments during flight operations. This periodic monitoring approach provides sufficient data for collision prevention while significantly reducing power consumption compared to continuous monitoring of all sensor parameters.
Solution Approach 2:
The system implements feedback control where the control unit receives status information from sensors, analyzes it for abnormal conditions, and only triggers alerts or safety protocols when actual abnormalities are detected. This feedback mechanism allows the system to maintain high reliability for collision prevention by focusing computational and energy resources only on actual anomalies rather than continuously processing all sensor data.
3Ease of operation
If propeller failure detection is implemented through sensor measurement, then flight control is improved, but manufacturing complexity increases
Solution Approach 1:
The monitoring system is divided into independent modular components: sensor units that can be separately manufactured and tested, a control unit with standardized processing algorithms, and a communication module. This segmentation allows each component to be manufactured and validated independently, reducing overall manufacturing complexity while enabling sophisticated flight control through integrated operation of these modular elements.

AI summary
A method of analyzing a propeller status of a wireless aerial robot can include measuring status information related to the propeller status by a sensor of a propeller; determining whether an operation of the propeller is abnormal based on the status information; transmitting the status information and operation information regarding whether an operation of the propeller is abnormal to a control unit using short range wireless communication; and analyzing, by the control unit, a flight status of the wireless aerial robot based on the status information and the operation information regarding whether the operation of the propeller is abnormal.
