Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If spectroscopy systems use fixed ground-based stations with heavy equipment, then measurement precision is improved, but mobility and response time deteriorate
Solution Approach 1:
The system divides the spectroscopy equipment into two segments: heavy components (laser source, telescope, detector) remain at a fixed base station, while only a lightweight retroreflector is mounted on the UAV. This segmentation allows the UAV to be mobile and rapid while the base station provides high-precision measurement capabilities.
Solution Approach 2:
A retroreflector serves as an intermediary component mounted on the UAV. It receives laser light from the base station and reflects it back through the telescope to the detector, enabling the UAV to participate in the measurement process without carrying heavy spectroscopy equipment.
2Adaptability or versatility
If UAVs carry all spectroscopy equipment, then system versatility is improved, but payload weight and power consumption worsen
Solution Approach 1:
The heavy and power-intensive components of the spectroscopy system (laser source, telescope, detector) are extracted from the UAV and relocated to a fixed base station. Only the essential retroreflector remains on the UAV, dramatically reducing payload weight while preserving full system functionality through the distributed architecture.
3Measurement precision
If traditional spectroscopy systems are used for atmospheric monitoring, then detection capability is improved, but real-time three-dimensional mapping capability deteriorates
Solution Approach 1:
The system transitions from traditional ground-based two-dimensional monitoring to three-dimensional atmospheric mapping by deploying UAVs in aerial space. The combination of aerial positioning data with spectroscopic measurements enables construction of three-dimensional plume distributions, adding a spatial dimension to the monitoring capability.
