Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the optical system is manually reconfigured to view the surgical site from multiple angles, then the surgeon can obtain different viewing angles, but the time required and surgeon distraction increase significantly
Solution Approach 1:
The system pre-configures multiple predetermined viewing positions for the optical system before the surgical procedure begins. These positions are saved in the controller's memory, allowing the surgeon to quickly switch between angles without manual reconfiguration during the procedure, thus reducing time loss while maintaining versatility.
Solution Approach 2:
The system creates digital copies of the surgical site view from multiple predetermined angles and stores them in memory. The surgeon can access these stored views by selecting corresponding position indicators, eliminating the need for physical repositioning of the optical system and reducing the time required to switch viewing angles.
2Adaptability or versatility
If the optical system is frequently repositioned during surgery, then multiple viewing angles are achieved, but the complexity of operation increases
Solution Approach 1:
The system creates digital representations of multiple viewing angles and stores them as selectable options. The surgeon interacts with a simplified interface displaying position indicators corresponding to pre-saved angles, reducing operational complexity while maintaining the ability to access multiple viewing perspectives.
Solution Approach 2:
The controller is designed with multi-functionality, serving both as a position memory storage device and a user interface for selecting viewing angles. This integrated design simplifies operation by combining multiple functions into a single system that the surgeon can control through a unified interface.
3Adaptability or versatility
If manual reconfiguration of the optical system is performed, then viewing angles are changed, but surgeon distraction and potential trauma to the patient increase
Solution Approach 1:
Multiple viewing positions are pre-configured and saved in the system before the surgical procedure begins. This preliminary setup eliminates the need for frequent manual adjustments during surgery, reducing surgeon distraction and minimizing the risk of accidental trauma to the patient from repeated repositioning operations.
Solution Approach 2:
The system stores digital copies of viewing angles in memory, allowing the surgeon to switch between pre-saved perspectives without physically moving the optical system. This reduces operational disturbances and minimizes potential harm to the patient while maintaining the ability to view the surgical site from multiple angles.

AI summary
A medical navigation system is provided including a surgical positioning system for positioning a payload during a medical procedure. The medical navigation system has a robotic arm having a plurality of joints, the robotic arm forming part of the surgical positioning system and having an end effector for holding the payload, an input device for providing input, and a controller electrically coupled to the robotic arm and the input device. The controller has a processor coupled to a memory and the controller is configured to perform the following during the medical procedure: position the robotic arm in a first position by providing a first positioning signal to the robotic arm; save the first position in the memory as a first saved position in response to a signal received from the input device; position the robotic arm in a second position by providing a second positioning signal to the robotic arm; and return the robotic arm to the first position by loading the first saved position from the memory and providing the first positioning signal to the robotic arm when an input is received from the input device corresponding to a command to return to the first saved position.
