Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the control device monitors and accumulates operational data to detect anomalies, then the reliability of the unmanned flying object is improved, but the device complexity increases
Solution Approach 1:
The control device integrates multiple functions including voltage detection, current detection, temperature detection, data accumulation in storage device, and automatic power adjustment all within a single control unit. This multi-functional integration improves flight safety through comprehensive monitoring while avoiding the need for multiple separate devices that would increase overall system complexity
Solution Approach 2:
The control device continuously monitors operational parameters (voltage, current, temperature) and automatically adjusts the power supplied to the rotor blade motor based on detected anomalies. This closed-loop feedback mechanism enables real-time safety improvements without requiring complex external intervention systems
2Object-affected harmful factors
If the control device reduces power to the rotor blade motor upon detecting anomalies, then the harmful effects are reduced, but the productivity decreases
Solution Approach 1:
The control device applies partial power reduction only to the affected rotor blade motor when anomalies are detected, rather than shutting down the entire system. This selective action reduces crash risk by mitigating the specific problem while maintaining partial flight capability, thereby preserving more flight time compared to complete system shutdown
Solution Approach 2:
The control device accumulates operational data in a storage device during normal operation, creating a historical record that cushions against complete system failure. This data accumulation enables post-flight analysis and continuous improvement, reducing the impact of crashes while maintaining full productivity during normal operation
