Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a control console uses traditional control mechanisms for surgical mechanical arms, then the device complexity is reduced, but the surgical precision and safety are compromised due to misalignment and collisions
Solution Approach 1:
The control console creates a virtual copy of the surgical site geometry and mechanical arm configurations. This digital replica allows the system to simulate and predict arm movements, camera views, and potential collisions before executing actual surgical actions, thereby improving precision without proportionally increasing physical complexity
Solution Approach 2:
The system performs preliminary calculations and predictions of mechanical arm trajectories and camera views before surgical procedures begin. By pre-computing safe movement paths and potential collision zones based on the virtual surgical site model, the system prevents misalignment and collisions during actual surgery
2Ease of operation
If the control console aligns input arm configuration with camera view, then the ease of operation is improved, but the device complexity increases due to additional sensors and processors
Solution Approach 1:
The control console automatically adjusts the virtual camera view to match the operator's physical arm configuration without requiring manual synchronization. The system uses sensors to detect arm position and autonomously updates the virtual model, making the control intuitive while automating the complexity-handling aspects
Solution Approach 2:
The system continuously monitors the operator's input arm configuration through sensors and provides real-time feedback by adjusting the virtual camera view accordingly. This closed-loop feedback mechanism creates an intuitive control experience where the virtual representation naturally follows the physical controller state
3Reliability
If the control console uses multiple sensors to monitor arm configuration, then the reliability is improved, but the loss of time increases due to data processing requirements
Solution Approach 1:
The system pre-processes sensor data and maintains an updated virtual model of the surgical site and arm configurations before critical surgical moments. By having the predictive model ready in advance, the system can quickly query predicted arm positions and camera views without performing complex calculations in real-time during surgery
