Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If current web mapping services and driver assistance systems are used, then basic mapping and navigation functions are provided, but detailed information on material properties and composition of objects is insufficient
Solution Approach 1:
The system segments the analysis process into distinct functional modules: imaging means for data collection, assigning means for coordinate assignment, and determining means for material property analysis. This segmentation allows each module to specialize in specific tasks, reducing overall system complexity while comprehensively capturing material property information through spectral library matching
Solution Approach 2:
The patent introduces spectral library data as an intermediary between the imaging system and material property determination. The spectral library serves as a reference database that mediates the conversion of raw spectral information into meaningful material property data, enabling detailed material analysis without requiring direct complex interaction between all system components
2Measurement precision
If detailed three-dimensional models with material properties are generated, then object analysis accuracy is improved, but data processing time and computational resources increase
Solution Approach 1:
The system performs preliminary actions by pre-establishing spectral library data containing reference spectral information for various materials. This preliminary preparation allows the determining means to quickly match acquired spectral information against pre-organized reference data, reducing real-time processing time while maintaining high measurement precision for material property determination
Solution Approach 2:
The patent uses spectral copying by acquiring spectral information from objects and comparing it with spectral library copies of known materials. This copying approach enables rapid identification of material properties by matching spectral patterns without requiring direct physical analysis, thus reducing processing time while maintaining accuracy
3Measurement precision
If spectral information is recorded and compared with spectral library data, then material properties and degradation states are determined accurately, but device complexity increases
Solution Approach 1:
The determining means is designed with multi-functionality, capable of performing multiple operations: acquiring spectral information, comparing it with spectral library data, determining material properties, and assessing degradation states. This universal function consolidation reduces the need for separate specialized devices, thereby managing device complexity while achieving high measurement precision across multiple analysis dimensions
