Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If hyperspectral imaging is used to collect detailed spectral information, then measurement precision is improved, but processing time and communication bandwidth requirements increase significantly
Solution Approach 1:
The patent extracts only the essential spectral bands needed for identifying materials of interest from the full hyperspectral spectrum. By selecting specific wavelength bands based on spectral library matching, the system retrieves sufficient information for discrimination while eliminating redundant data, thus reducing processing time and communication bandwidth requirements.
Solution Approach 2:
The patent applies local quality by configuring sensors to collect data at specific wavelength bands tailored to the particular geographic area and materials of interest. Rather than uniformly collecting all spectral bands across the entire spectrum, the system adapts the spectral configuration to local conditions, optimizing information quality while minimizing data volume.
2Adaptability or versatility
If hyperspectral sensing is used to ease spectral band planning, then adaptability is improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent performs preliminary action by pre-configuring spectral bands based on simulated spectral representations and spectral library matching before actual data collection. This advance planning allows the system to adapt to different geographic areas and materials of interest without requiring complex real-time processing, as the optimal spectral configuration is determined in advance.
Solution Approach 2:
The patent uses spectral library copies to represent target materials and background elements. By matching sensor configurations against these spectral templates, the system achieves adaptability across different scenarios without requiring complex processing, as the spectral signatures serve as reference models for band selection.
3Measurement precision
If sensor characteristics are chosen to maximize discriminants between target and background, then measurement precision is improved, but device complexity increases due to unknown characteristics
Solution Approach 1:
The patent employs feedback by using spectral library matching to determine optimal sensor characteristics based on the specific target and background materials in the geographic area of interest. The system receives feedback from spectral simulations and adjusts sensor configuration accordingly, achieving high discrimination precision without requiring complex manual setup, as the optimal configuration is determined through systematic spectral analysis.
