Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UAV uses a fixed control system without payload adaptation, then the device complexity is reduced, but the reliability deteriorates due to potential unsafe maneuvers
Solution Approach 1:
The system implements feedback by continuously monitoring payload characteristics through sensors and using this information to dynamically adjust flight control commands. The microprocessor receives payload data, predicts flight responses, and modifies commands in real-time to maintain safe operation, creating a closed-loop control system that adapts to varying payload conditions.
Solution Approach 2:
The control system transitions from a static, fixed configuration to a dynamic adaptive system. The microprocessor dynamically adjusts flight commands based on real-time payload characteristics and predicted flight responses, allowing the system to optimize performance and safety for different payload types and conditions without requiring multiple fixed control systems.
2Adaptability or versatility
If the UAV implements dynamic payload adaptation, then the adaptability is improved, but the device complexity increases due to additional sensors and processing
Solution Approach 1:
The system achieves universality by designing a multi-functional microprocessor-based control system that can handle various payload types through a unified interface. The same hardware platform performs multiple functions including payload identification, characteristic analysis, flight prediction, and command modification, eliminating the need for separate specialized systems for different payload types.
Solution Approach 2:
The microprocessor-based controller serves as an intermediary layer between the payload and the flight control system. It receives payload identification data and characteristics, processes this information through prediction algorithms, and translates payload-specific requirements into modified flight commands, mediating between diverse payload types and the universal flight control system.
3Ease of operation
If the UAV modifies flight commands based on payload characteristics, then the pilot control is improved, but the loss of information increases due to command modification
Solution Approach 1:
The system performs preliminary action by predicting flight responses before executing command modifications. The microprocessor calculates expected flight behavior based on payload characteristics and uses these predictions to pre-adjust commands in a way that maintains safety while preserving pilot intent, rather than making reactive modifications that could lose information.
Solution Approach 2:
The command modification process incorporates feedback by continuously monitoring flight responses and comparing them against predictions. This feedback loop ensures that modifications remain within safe parameters while preserving the essential pilot intent, allowing the system to maintain command integrity by verifying that modified commands still achieve the desired flight objectives.
