Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional hyperspectral imaging devices are used, then detection capability for camouflaged objects and chemical hazards is improved, but device portability and ease of operation deteriorate due to large size and heavy weight
Solution Approach 1:
The device segments the imaging function into multiple specialized sensors (hyperspectral sensor, thermal sensor, visible light sensor, millimeter-wave sensor) that operate in parallel at different spectral bands. Each sensor captures specific information independently, and the computing unit integrates these segmented data streams to achieve comprehensive detection without requiring a single bulky hyperspectral system
Solution Approach 2:
The wearable device integrates multiple imaging modalities (hyperspectral, thermal, visible light, and millimeter-wave) into a single multi-functional platform. This universal device can detect various targets (camouflaged objects, chemical hazards, thermal signatures) using different spectral bands simultaneously, replacing multiple separate specialized devices with one portable unit
2Measurement precision
If conventional hyperspectral imaging devices are used, then detection capability is improved, but device portability deteriorates due to bulky structure
Solution Approach 1:
The device employs a nested architecture where multiple imaging sensors and processing units are integrated within a compact wearable form factor. The sensors and computing components are nested within the head-mounted display structure, allowing the system to maintain advanced detection capabilities while minimizing external volume and achieving wearable portability
3Measurement precision
If conventional hyperspectral imaging devices are used, then detection capability is improved, but ease of operation deteriorates due to complex calibration and post-processing requirements
Solution Approach 1:
The computing unit automatically performs calibration, data fusion, and threat level determination without requiring specialist intervention. The system self-calibrates by co-registering data from multiple sensors and automatically processes the integrated data to determine threat levels and geospatial locations, eliminating the need for manual post-processing steps
Solution Approach 2:
The device provides real-time visual feedback through the head-mounted display, showing threat levels and geospatial locations as the user moves. The system continuously monitors environmental data and provides immediate visual feedback about detected hazards, eliminating the need for offline analysis and allowing operators to make real-time decisions
4Measurement precision
If conventional hyperspectral imaging devices are used, then detection capability is improved, but adaptability to field operations deteriorates due to power consumption and operating conditions
Solution Approach 1:
The device dynamically adapts its operation to field conditions by integrating multiple sensor modalities that can function independently or in combination. The system can operate in various lighting conditions (visible light sensor for daytime, thermal sensor for nighttime), different atmospheric conditions (millimeter-wave for penetrating obscurants), and provides continuous real-time visualization that adapts to the user's movement and field of view
