Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current research focuses on longitudinal positions of disasters, then longitudinal position analysis is improved, but transverse position analysis is neglected
Solution Approach 1:
The patent introduces transverse position analysis as a new dimension alongside the existing longitudinal position analysis. By using polar coordinate system with angle attributes and distance ratio attributes, the method expands the analysis from one dimension (longitudinal) to two dimensions (both longitudinal and transverse), thereby resolving the contradiction by adding missing dimensional information without sacrificing existing analysis capabilities
2Device complexity
If slope is simplified into triangle for analysis, then calculation complexity is reduced, but geometric accuracy may be compromised
Solution Approach 1:
The patent divides the complex slope geometry into a triangular framework with three vertices (A, B, C) and uses terrain points within this triangle for analysis. This segmentation approach simplifies the overall slope into manageable geometric elements while maintaining sufficient accuracy for disaster position characterization, resolving the contradiction between computational simplicity and geometric accuracy
3Measurement precision
If angle attribute transformation is applied, then transverse position characterization is improved, but calculation steps increase
Solution Approach 1:
The patent transforms the initial angle attribute into a target angle attribute using a predetermined transformation coefficient. This parameter change enables accurate characterization of transverse positions while maintaining a systematic calculation approach. The transformation coefficient is derived from the triangle's geometric properties, ensuring that the additional calculation step serves a clear analytical purpose rather than being merely computational complexity
