Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If destructive methods (drilling holes, visual inspections) are used to determine component composition, then measurement precision is improved, but the component is damaged and loss of substance occurs
Solution Approach 1:
The patent replaces mechanical destructive inspection methods (drilling, physical sampling) with electromagnetic radar-based detection. The radar system uses electromagnetic waves to penetrate and analyze component structure non-destructively, obtaining composition information without physical contact or material removal.
Solution Approach 2:
The patent introduces electromagnetic waves as an intermediary medium to obtain composition information. Instead of directly contacting or damaging the component, radar waves serve as a mediator that carries structural information back to the analysis system, enabling indirect but accurate measurement.
2Loss of substance
If radar data analysis is used to determine component composition, then loss of substance is avoided, but measurement precision may be insufficient for complex multi-layer structures
Solution Approach 1:
The patent segments the component structure into individual layers for separate analysis. The radar system detects reflections from each layer interface, and the analysis method processes these reflections to determine the thickness and material properties of each layer independently, enabling precise characterization of multi-layer structures.
Solution Approach 2:
The patent adds the dimension of electromagnetic wave interaction with material permittivity to the analysis. By measuring how radar waves reflect and transmit through different layers based on their permittivity values, the system can distinguish between different materials and determine layer composition with higher precision.
3Adaptability or versatility
If multiple analysis methods are considered for different scenarios, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements a dynamic analysis method selection process that adapts to the specific measurement scenario. The system evaluates the component characteristics and measurement requirements, then automatically selects the most appropriate analysis method from available options, optimizing both accuracy and computational efficiency for each case.
Solution Approach 2:
The patent enables the analysis system to automatically determine which analysis method to use based on the radar data characteristics and component properties. The system self-adjusts its analysis approach without requiring manual intervention, simplifying the user interface while maintaining high adaptability to different measurement scenarios.
