Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a ground work machine is connected to the body of the unmanned aerial vehicle, then payload capability is improved, but safety and reliability deteriorate due to increased risk during flight abnormalities
Solution Approach 1:
The patent applies beforehand cushioning by equipping the unmanned aerial vehicle with parachutes and airbags before flight operations. These safety devices are pre-installed and can be deployed when abnormalities occur, cushioning the impact of potential crashes and protecting both the aircraft and ground work machine from damage.
Solution Approach 2:
The patent applies segmentation by dividing the connection system into separable components. The ground work machine can be detached from the aircraft body through a release mechanism controlled by the control device, allowing the aircraft to separate from the payload during emergencies while maintaining the ability to operate together during normal conditions.
2Reliability
If safety devices (parachute and airbag) are added to the unmanned aerial vehicle, then reliability is improved, but device complexity increases
Solution Approach 1:
The control device serves multiple functions: it controls normal flight operations and simultaneously manages emergency safety functions including detecting abnormalities, triggering parachute deployment, activating airbags, and controlling the release mechanism. This multi-functionality reduces the need for separate dedicated control systems for each function.
Solution Approach 2:
The patent merges the safety control functions with the existing flight control device. Rather than creating separate independent control systems for parachute deployment, airbag activation, and payload release, these functions are integrated into the unified control device, simplifying the overall system architecture.
3Reliability
If the connection between ground work machine and body can be released during flight, then safety is improved, but ease of operation deteriorates due to additional control requirements
Solution Approach 1:
The system applies self-service through automatic abnormality detection and emergency response. The control device automatically detects flight abnormalities through sensor data, determines when release is necessary, and executes the separation sequence without requiring manual pilot intervention, thereby maintaining ease of operation while ensuring safety.
Solution Approach 2:
The control device continuously receives feedback from sensors monitoring flight parameters, rotor status, and system health. This real-time feedback enables the control device to automatically detect abnormalities and trigger appropriate safety responses, including potential payload release, based on current flight conditions rather than requiring pilot judgment.
