Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic image analysis is implemented to determine stent placement position, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system performs automatic stent placement by having the observation device capture images and the control device automatically analyze them to determine optimal placement positions, eliminating the need for manual user input and making the system self-sufficient in the positioning task
Solution Approach 2:
The patent replaces manual mechanical positioning operations with an automated image analysis system that uses observation devices and control algorithms to determine stent placement positions based on analyzed images of the target site
2Measurement precision
If manual user input for target positioning is required, then measurement precision may be improved, but productivity decreases
Solution Approach 1:
The system automatically captures observation images and determines stent placement positions without requiring manual user input for target positioning, thereby eliminating time-consuming manual operations while maintaining positioning accuracy through automated image analysis
Solution Approach 2:
The observation device captures images of the target site before stent placement, and the control device analyzes these images in advance to determine the optimal placement position, preparing all necessary information beforehand to enable rapid execution of the placement procedure
