Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If static models and simulations are used for detect and avoid systems, then system complexity is reduced and ease of manufacture is improved, but real-time monitoring capability and adaptability to environmental conditions deteriorate
Solution Approach 1:
The patent implements a dynamic model that continuously updates detection range calculations based on real-time environmental conditions, vehicle characteristics, and system performance. The system transitions from static pre-defined parameters to dynamic real-time adaptation, allowing the detect and avoid system to adjust its operational parameters on-the-fly to maintain safety while responding to changing conditions.
2Device complexity
If static models are used, then device complexity is reduced, but real-time monitoring and update capability deteriorate
Solution Approach 1:
The system incorporates continuous feedback loops that monitor environmental conditions, sensor performance, and system operational status. This feedback enables real-time updates to the detection range model, ensuring the system maintains reliable collision avoidance capabilities by adapting to changing conditions and system degradation over time.
3Measurement precision
If extensive simulations are performed to establish static models, then measurement precision is improved, but loss of time and productivity deteriorate
Solution Approach 1:
The patent performs extensive simulations and model development in advance to establish the foundational detection and avoidance model. This preliminary action creates a robust framework that can then operate efficiently in real-time with minimal computational overhead during actual flight operations, balancing thorough analysis with operational speed.
4Ease of operation
If static detection ranges are used, then ease of operation is improved, but adaptability to changing environmental conditions and system performance deteriorates
Solution Approach 1:
The system dynamically changes operational parameters including detection range, alert thresholds, and avoidance criteria based on real-time conditions such as environmental factors, vehicle speed, sensor performance, and system latency. This allows the system to maintain ease of automatic operation while adapting to varying operational contexts.

AI summary
An apparatus is provided for detecting and avoiding objects in real-time. The apparatus includes a first sensor that collects environmental data and a second sensor that collects external data corresponding to an external object within a detection range from the apparatus. The apparatus further includes a processor that, in real-time, calculates a minimum distance to avoid the external object, based at least in part on the environmental data and the external data, monitors the environmental data and the external data, and controls the apparatus to avoid the external object based on the calculated minimum distance and the monitored environmental data and external data.
