Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional hand drafted maps are used for hazardous area classification, then the process can be completed with basic tools, but the method is time-consuming and requires advanced drafting skills
Solution Approach 1:
The patent replaces manual drafting processes with automated computer-based calculations and graphical user interface tools. The system automatically performs hazardous area classification calculations and generates visual representations, eliminating the need for manual drafting skills and significantly reducing the time required for classification.
Solution Approach 2:
The system enables users to perform hazardous area classification independently through automated calculations and intuitive graphical interfaces. The software self-generates classification results, hazard area visualizations, and compliance reports without requiring external drafting expertise or manual intervention in the calculation process.
2Loss of information
If conventional hand drafted maps are used, then the process can be completed manually, but the maps do not show certain information such as extent of hazardous ranges or heights and elevations
Solution Approach 1:
The patent transitions from two-dimensional hand-drawn maps to three-dimensional visual representations that display hazardous areas with elevation, height, and spatial extent information. The system generates 3D models and cross-sectional views that provide comprehensive spatial information about hazardous zones, including vertical dimensions that were impossible to convey in conventional 2D drafting.
3Measurement precision
If detailed calculations involving complicated mixtures of materials are performed manually, then accuracy can be achieved, but the process becomes difficult and time-consuming
Solution Approach 1:
The patent replaces manual calculation processes with automated computer-based algorithms that perform complex hazardous area classification calculations. The system automatically processes material composition data, performs vapor pressure and concentration calculations, and determines classification boundaries with high precision, eliminating the difficulty and time consumption of manual calculations while maintaining accuracy.
