Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual catheter manipulation is used, then surgeon dexterity and control are required, but the complexity of setup and difficulty of operation increase
Solution Approach 1:
The patent replaces manual mechanical manipulation of catheters with an automated robotic drive system. The robotic system uses motorized actuators to control catheter positioning, eliminating the need for manual manipulation by the surgeon. This substitution reduces operational complexity while maintaining precise control through automated navigation and positioning mechanisms.
Solution Approach 2:
The robotic drive system performs self-positioning and self-navigation functions that previously required manual surgeon intervention. The system autonomously manages catheter advancement, retraction, and positioning through integrated control algorithms and sensors, reducing the skill barrier and operational complexity for users.
2Reliability
If multiple coaxial catheters are used, then neurovascular procedures can be performed, but frictional interplay causes inadvertent catheter motion
Solution Approach 1:
The robotic drive system replaces manual control of multiple coaxial catheters with automated individual control. Each catheter is independently actuated by separate robotic actuators, eliminating frictional interplay between manually manipulated catheters. The system precisely controls each catheter's position and movement without inadvertent motion caused by manual handling.
Solution Approach 2:
The patent segments the control of each catheter into independent robotic actuators. Instead of manually manipulating multiple catheters simultaneously (which causes friction and inadvertent motion), the robotic system controls each catheter separately through dedicated actuators, ensuring precise and stable positioning of each device.
3Productivity
If supra-aortic access is achieved, then neurovascular treatment is possible, but the setup process is time consuming
Solution Approach 1:
The robotic drive system performs preliminary positioning and preparation of catheters and access devices before the actual neurovascular procedure. The system pre-navigates catheters to target positions and pre-positions access devices, eliminating time-consuming manual setup steps and accelerating the overall procedure timeline.
Solution Approach 2:
The automated robotic system replaces time-consuming manual setup procedures with rapid automated positioning. The robotic actuators quickly advance, retract, and position catheters and access devices without the delays associated with manual manipulation, significantly reducing setup time while maintaining procedural accuracy.
4Measurement precision
If manual dexterity is required for catheter control, then precise maneuvers can be performed, but the need for trained interventionalists limits availability
Solution Approach 1:
The robotic drive system replaces the need for manual dexterity with automated precision control. The system uses motorized actuators, sensors, and control algorithms to achieve precise catheter maneuvers without requiring highly trained interventionalists. This democratizes access to complex neurovascular procedures by reducing the skill barrier while maintaining precision.
Solution Approach 2:
The robotic system performs self-navigation and self-positioning functions with high precision, eliminating the need for manual dexterity. The automated control system manages complex maneuvers autonomously, making precise neurovascular procedures accessible to facilities without highly specialized interventionalists, thereby increasing overall availability.
