Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-resolution radars or optical sensors are used for trajectory prediction, then measurement precision is improved, but device complexity and energy consumption increase
Solution Approach 1:
The detection space is segmented into multiple sectors, with each sector monitored by a simple sector radar. This allows the system to achieve comprehensive coverage and precise trajectory prediction through distributed simple sensors rather than a single complex high-resolution radar, resolving the contradiction between measurement precision and device complexity
Solution Approach 2:
A computing unit acts as an intermediary that fuses data from multiple simple sector radars to achieve accurate trajectory prediction. The computing unit processes sectorized radar data to determine object trajectories, enabling precise measurement through data fusion rather than through a single complex sensor system
2Reliability
If complex radar systems are used for collision avoidance, then reliability is improved, but use of energy increases
Solution Approach 1:
The radar system is segmented into multiple simple sector radars that each monitor specific sectors. This segmentation allows the system to achieve reliable collision avoidance through coordinated simple sensors rather than a single energy-intensive complex radar, resolving the contradiction between reliability and energy consumption
Solution Approach 2:
The sector radars perform periodic scanning of their respective sectors to detect objects and track trajectories. This periodic action enables reliable collision detection and avoidance while minimizing energy consumption compared to continuous operation of high-power radars
3Adaptability or versatility
If non-cooperative collision avoidance is implemented, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system uses segmented sector radars that independently monitor specific sectors and provide data to a computing unit. This segmentation enables non-cooperative collision avoidance with simple components, as each sector radar operates independently without requiring complex coordination, resolving the contradiction between adaptability and device complexity
Solution Approach 2:
Each sector radar independently detects objects in its sector and provides data to the computing unit, which autonomously processes the information for trajectory prediction and collision avoidance. This self-service approach enables non-cooperative operation without requiring complex communication systems between aircraft, achieving adaptability with simple devices
