Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple tools are manipulated manually during gynecological procedures, then the surgeon has direct control, but the precision and coordination of tool movement deteriorates
Solution Approach 1:
The robotic system autonomously coordinates multiple tools (endoscope, stabilizing device, treatment tool) without requiring manual intervention for each tool's positioning and movement. The system self-manages the complex coordination of multiple implements, achieving precise manipulation while reducing the burden on the surgeon.
2Stability of the object's composition
If the cervix is stabilized using traditional manual techniques, then the procedure can proceed, but the stability and positioning accuracy deteriorates
Solution Approach 1:
The system replaces manual mechanical stabilization with a robotically controlled stabilizing device that can precisely position and hold the cervix. The robotic arm provides controlled mechanical force to stabilize the cervix, improving positioning accuracy while reducing the physical difficulty for the surgeon.
3Productivity
If traditional surgical systems are used for tissue resection, then the procedure is straightforward, but the resection precision and efficiency deteriorates
Solution Approach 1:
The robotic system integrates multiple functions into a single platform: the robotic arm can manipulate the endoscope for visualization, the stabilizing device for cervix positioning, and the treatment tool for tissue resection. This multi-functional approach achieves precise and efficient resection while managing system complexity through integration.
4Adaptability or versatility
If multiple tools are used simultaneously, then comprehensive treatment is achieved, but the coordination and control precision deteriorates
Solution Approach 1:
The robotic system uses feedback from sensors and controllers to continuously monitor and adjust the position and movement of multiple tools. The controller receives information about tool positions and makes real-time adjustments to maintain precise coordination, enabling versatile tool configuration while preserving movement precision.
