Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If expensive digitization programs are used to convert electronic graphs to raw data, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent introduces a graph analysis application as an intermediary tool that runs within existing graph viewing software. This application acts as a mediator between the user and the graph data, providing data extraction and analysis capabilities without requiring complex standalone digitization software. The solution leverages the existing graphical user interface and coordinate systems of the host application to perform measurements.
Solution Approach 2:
The system enables users to perform data extraction and analysis operations themselves through an intuitive interface. The graph analysis application provides tools for selecting data points, measuring distances, calculating areas, and extracting information directly from the displayed graph, eliminating the need for expensive specialized digitization software while maintaining accuracy.
2Device complexity
If rudimentary implements like pencil and ruler are used to read data from printed graphs, then device complexity is reduced, but measurement precision and productivity deteriorate
Solution Approach 1:
The patent replaces mechanical measurement tools (pencil, ruler) with a digital interface system. Users interact with the graph through a graphical user interface that displays coordinate information, allows precise point selection, and provides automated calculations. The system substitutes manual mechanical measurements with electronic detection and computation, significantly improving accuracy while maintaining ease of use.
3Productivity
If electronic graphs are used instead of printed graphs, then productivity is improved, but measurement precision deteriorates due to lack of raw data
Solution Approach 1:
The graph analysis application performs preliminary actions by detecting the graphical elements, axes, and scale information from the displayed graph image. It establishes the coordinate transformation relationships between the graphical display and the actual data values before the user begins measurements. This preliminary processing enables accurate data extraction without requiring the original raw data files.
4Adaptability or versatility
If multi-dimensional graphs are analyzed, then adaptability is improved, but device complexity and difficulty of detection increase
Solution Approach 1:
The patent addresses multi-dimensional graphs by extending the graphical user interface to accommodate additional dimensions. The system can display and measure data across multiple axes simultaneously, providing tools for analyzing three-dimensional plots and higher-dimensional data representations. The interface adapts to show appropriate controls and measurement tools for each dimension, making complex data accessible and measurable.
