Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If ground-based detection systems use single-wavelength band infrared detection or dual-wavelength band detection, then the system structure is simple, but the detection rate is low and false alarm rate is high
Solution Approach 1:
The detection system is segmented into multiple independent wavelength band detection modules (infrared, visible light, laser ranging) that operate in parallel. Each module processes specific wavelength bands separately, then results are fused to improve detection rate while maintaining manageable system complexity through modular architecture
Solution Approach 2:
The detection system is designed to perform multiple detection functions across different wavelength bands simultaneously. The same platform and processing system handle infrared detection, visible light imaging, and laser ranging, making the system multi-functional and improving reliability without proportionally increasing complexity
2Device complexity
If detection platforms are fixed at specific locations, then the system structure is simple, but mobile deployment ability is low and situational awareness capability is limited
Solution Approach 1:
The detection platform transitions from fixed to mobile configuration, mounted on vehicles that can be rapidly deployed to different locations. The system maintains operational capability during movement and can quickly reposition to provide situational awareness across multiple scenarios, enhancing adaptability while using standardized mobile platforms to control complexity
3Device complexity
If ground-based radars are used for detection, then the system structure is simple, but detection of low, slow and small targets is difficult due to low-altitude background clutter
Solution Approach 1:
Different wavelength bands are used to detect different characteristics of targets at different altitudes. Infrared detection is optimized for low-altitude targets where thermal contrast is useful, while visible light and laser ranging provide complementary information at various ranges, creating locally optimized detection quality for different operational zones
Solution Approach 2:
Multiple wavelength bands act as intermediaries to overcome the limitation of single radar detection in cluttered environments. The fusion of infrared, visible light, and laser ranging data provides intermediate detection results that collectively improve measurement precision by cross-validating target detections across different spectral domains
4Device complexity
If conventional detection systems are used, then the system structure is simple, but detection range is limited and long-range target detection is not achievable
Solution Approach 1:
The system merges multiple detection technologies (infrared detection, visible light imaging, laser ranging) into an integrated platform. The laser ranging module specifically extends detection range by providing active illumination and time-of-flight measurement capability, while infrared and visible light modules provide complementary detection at extended ranges, achieving long-range detection capability through technological combination
