Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional imaging systems are used for mobile platforms, then the system structure is simple, but the contrast and reliability under common environmental conditions are insufficient
Solution Approach 1:
The patent combines multiple spectral imaging sensors (visible, infrared, ultraviolet) into a single integrated imaging system. This merging of multiple sensing capabilities into one unified system provides reliable navigation under various environmental conditions while managing system complexity through integration rather than separate systems.
Solution Approach 2:
The multispectral imaging system is designed to function across multiple spectral bands simultaneously, making it universally applicable to different environmental conditions (day/night, various weather, different terrain). This multi-functionality allows a single system to replace multiple specialized imaging systems.
2Illumination intensity
If conventional imaging systems are used, then the device size is small, but the contrast under challenging environmental conditions is insufficient
Solution Approach 1:
The patent extends imaging from the traditional visible spectrum into additional spectral dimensions (infrared and ultraviolet). By capturing information in these additional spectral dimensions, the system achieves superior scene contrast and object differentiation without proportionally increasing physical volume, as multiple spectral channels are integrated into a compact sensor array.
3Measurement precision
If multispectral imaging system is implemented, then scene differentiation and object recognition are enhanced, but the device complexity increases
Solution Approach 1:
The multispectral imaging system is segmented into distinct spectral channel modules (visible, infrared, ultraviolet), each optimized for specific detection tasks. This segmentation allows independent optimization of each spectral band while maintaining overall system manageability through modular architecture.
Solution Approach 2:
The system changes the operational parameters by detecting electromagnetic radiation across multiple spectral bands rather than relying on a single band. This parameter change from monospectral to multispectral detection fundamentally improves object recognition accuracy by providing complementary information from different spectral regions.
4Reliability
If multispectral imaging system is implemented, then navigation reliability is improved, but the power consumption increases
Solution Approach 1:
The multispectral imaging system employs periodic scanning and frame capture rather than continuous high-power operation. By strategically timing captures across different spectral bands and using frame interpolation techniques, the system maintains navigation reliability while reducing overall power consumption compared to continuous full-power operation of all spectral channels.

AI summary
Thermal imaging and navigation systems and related techniques are provided to improve the operation of manned or unmanned mobile platforms, including passenger vehicles. A thermal imaging navigation system includes a thermal imaging system and a logic device configured to communicate with the thermal imaging system. The thermal imaging system includes a thermal imaging module configured to provide thermal image data corresponding to a projected course for a mobile platform. The logic device is configured to receive the thermal image data, receive orientation and/or position data corresponding to the thermal image data, and generate maneuvering obstacle information corresponding to the projected course based, at least in part, on the orientation and/or position data and/or the thermal image data.
