Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If established setup guidance is followed for port placement, then accurate positioning is achieved, but setup time increases
Solution Approach 1:
The system performs preliminary calculation of port placement locations using patient-specific anatomical data and procedure type before the actual surgical procedure. The template is pre-configured with optimal port positions based on computational algorithms that consider patient anatomy, eliminating the need for time-consuming manual measurement and positioning during surgery.
Solution Approach 2:
The system creates a template that copies and transfers the calculated port placement locations onto the patient's body. This template serves as a reproducible guide that accurately reproduces the computationally determined optimal positions, ensuring measurement precision while reducing setup time through direct template placement rather than manual positioning.
2Manufacturing precision
If manual port placement measurement is performed, then positioning accuracy is achieved, but procedural efficiency decreases
Solution Approach 1:
The system replaces manual mechanical measurement and positioning methods with an automated computational system. A computer calculates optimal port locations based on patient anatomical data and procedure type, then a printing device creates a template that guides placement. This substitution of automated computation and template-based guidance for manual measurement significantly improves procedural efficiency while maintaining or enhancing placement precision.
Solution Approach 2:
The system changes the parameters of port placement from manual estimation to computationally optimized positions. By altering the methodology from subjective manual measurement to objective algorithmic calculation based on patient-specific anatomical parameters, the system achieves both higher precision and improved efficiency through automated determination of optimal placement locations.
3Measurement precision
If template printing is performed, then port placement accuracy is improved, but device complexity increases
Solution Approach 1:
The system employs a multi-functional integrated approach where a single template serves multiple purposes: it displays calculated port locations, provides visual guidance for placement, and can be adapted for different procedure types. The printing device integrates computational output directly into a physical template that combines multiple functions (guidance, measurement reference, and positioning aid) into one component, reducing the need for multiple separate tools and minimizing the practical complexity increase.
