Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual cannulation is performed by physicians or trained personnel, then cannulation can be performed with current equipment and skills, but the quality and reliability vary due to individual abilities and temporal variations
Solution Approach 1:
The patent replaces the manual mechanical cannulation system with an automated robotic system. The cannulation robot performs detection, manipulation, and cannulation tasks automatically using sensors, actuators, and control algorithms, eliminating variability caused by individual operator skills and temporal factors while maintaining high reliability through standardized automated procedures
Solution Approach 2:
The system performs self-service through automated detection and manipulation of the blood vessel. The robotic system independently identifies the target vessel, adjusts its position and dimensions using actuators, and executes cannulation without requiring continuous manual intervention, thereby ensuring consistent quality and reducing operator-dependent variability
2Reliability
If standardization of cannulation is implemented, then treatment quality can be reliably ensured, but the complexity of the system increases
Solution Approach 1:
The cannulation system is segmented into distinct functional modules: a detection apparatus for identifying blood vessels, a manipulation apparatus for adjusting vessel position and dimensions, and a cannulation apparatus for performing the actual cannulation. Each module operates independently with standardized protocols, enabling reliable treatment quality while managing complexity through modular design
Solution Approach 2:
The system standardizes cannulation by controlling and optimizing specific parameters such as blood vessel position, vessel dimensions (diameter), and cannulation angles. By automatically adjusting these parameters within predetermined ranges and maintaining them within tolerance values, the system ensures consistent treatment quality while managing complexity through parameter-based control rather than procedural complexity
3Reliability
If blood vessel position and dimensions are manipulated to optimize cannulation, then cannulation success rate improves, but the manipulation process adds complexity to the procedure
Solution Approach 1:
The manipulation apparatus performs preliminary actions to optimize the blood vessel before cannulation is performed. The system adjusts the blood vessel position and dimensions in advance using actuators, ensuring the vessel is in the optimal state for cannulation. This preliminary manipulation simplifies the actual cannulation procedure and increases success rate by preparing the vessel in advance rather than requiring complex real-time adjustments during cannulation
