Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple surgical tools and energy sources are coordinated during procedures, then surgical functionality is enhanced, but system complexity and potential tissue trauma increase due to visibility restrictions and complex interactions between moving parts
Solution Approach 1:
The surgical system is divided into separate modular components including a robotic arm with drive system, a detachable surgical tool, and a control system. This segmentation allows each component to be optimized independently while reducing overall system complexity and improving manageability during procedures.
Solution Approach 2:
The robotic arm and drive system are designed to accommodate multiple different surgical tools through standardized interfaces and coupling mechanisms. This universality enables a single base system to perform various surgical functions by simply changing the attached tool, enhancing versatility without proportionally increasing complexity.
2Adaptability or versatility
If multiple surgical tools and energy sources are coordinated during procedures, then surgical functionality is enhanced, but tissue trauma increases due to visibility restrictions and complex interactions between moving parts
Solution Approach 1:
The control system incorporates feedback mechanisms that monitor the positions and interactions of multiple surgical tools in real-time. This feedback allows the system to automatically adjust tool movements and energy application to avoid harmful interactions and minimize tissue trauma while maintaining enhanced surgical functionality.
Solution Approach 2:
The system pre-plans and pre-coordinates the movements and energy application of multiple surgical tools before procedures begin. By anticipating potential harmful interactions between tools and energy sources, the system can pre-adjust trajectories, timing, and power levels to prevent tissue trauma before it occurs.
3Device complexity
If traditional surgical tool management systems are used, then system simplicity is maintained, but procedural efficiency decreases due to visibility restrictions and complex interactions between moving parts
Solution Approach 1:
The robotic system incorporates automated tool management capabilities including self-positioning, self-alignment, and automated coordination of multiple tools. This self-service functionality eliminates the need for manual intervention to manage complex tool interactions, thereby improving procedural efficiency without requiring proportionally more complex external control systems.
