Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement reference points are manually set on tomographic images for evaluating biological tissue movement, then measurement precision is improved, but device complexity and ease of operation deteriorate due to the cumbersome process of setting a large number of points
Solution Approach 1:
The system automatically performs functions that would otherwise require manual operator input. The measurement reference point setting unit automatically determines optimal measurement points based on image data analysis, eliminating the need for manual point-by-point selection by the operator while maintaining measurement accuracy
Solution Approach 2:
The system changes the parameter of measurement point selection from manual coordinate input to automated algorithmic determination. By transforming the operational parameter from user-defined positions to system-calculated positions based on tissue boundary detection and movement patterns, the system resolves the contradiction between precision and ease of operation
2Measurement precision
If a large number of measurement reference points are set for accurate tissue movement evaluation, then measurement precision is improved, but loss of time increases due to the tedious setting process
Solution Approach 1:
The system performs preliminary analysis of the tomographic images to automatically identify and set measurement reference points before the actual movement evaluation begins. This preliminary automated point selection eliminates the time-consuming manual setup phase while ensuring that sufficient measurement points are established for accurate subsequent analysis
Solution Approach 2:
The automated point setting system performs the time-consuming task of establishing measurement references without operator intervention, allowing the system to serve itself in the point selection process and significantly reducing the time loss associated with manual configuration
