Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multispectral imaging with optical filters is used, then signal visibility is enhanced and false positives are reduced, but device complexity increases
Solution Approach 1:
The system segments the electromagnetic spectrum into multiple spectral bands using optical filters, allowing detection of threat materials at different wavelengths. This segmentation enables the system to distinguish between genuine threats and false positives by analyzing spectral signatures across multiple bands, thereby improving measurement precision while managing complexity through modular filter implementation.
Solution Approach 2:
The imaging system is designed with multi-functionality to perform both standard imaging and spectral analysis using the same hardware platform. By integrating optical filters that can be switched or combined, the system achieves multiple detection capabilities (different spectral bands) without requiring entirely separate detection systems, thus improving accuracy while controlling overall device complexity.
2Loss of information
If 3D mapping and augmented reality overlay are implemented, then situational awareness and response efficiency are improved, but processing requirements and device complexity increase
Solution Approach 1:
The system transitions from 2D image display to 3D spatial mapping by constructing three-dimensional representations of the environment and overlaying threat information in spatial context. This dimensional enhancement provides operators with intuitive situational awareness showing threat locations, types, and concentrations in 3D space, improving information retention and response efficiency while managing processing complexity through efficient spatial data structures.
3Reliability
If automated confirmation through orthogonal detection is used, then false positive determinations are reduced, but detection time and system complexity increase
Solution Approach 1:
The system performs preliminary spectral characterization and pattern recognition automatically as part of the initial detection process. By pre-programming spectral signatures of known threat materials and implementing automated comparison algorithms, the system can quickly confirm or reject potential threats without requiring lengthy manual analysis, thus improving reliability while minimizing additional detection time.
