Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a robotic surgical system uses a multi-segment robotic arm with multiple detachable tools (endoscopic viewing assembly, stabilizing device, treatment tools), then the versatility and precision of gynecological procedures is improved, but the device complexity increases
Solution Approach 1:
The robotic arm is divided into multiple detachable segments including endoscopic viewing assembly, stabilizing device, and treatment tools. Each segment can be independently attached or detached from the robotic arm, allowing flexible configuration for different surgical needs while maintaining overall system versatility.
Solution Approach 2:
The robotic arm is designed as a universal platform that can accommodate multiple different tool types (endoscopic viewing, stabilization, treatment) through standardized coupling mechanisms. This allows a single robotic arm to perform multiple gynecological procedures with different tools, enhancing adaptability without requiring separate robotic systems for each function.
2Manufacturing precision
If the robotic arm integrates multiple motor drives for axial and rotational movements of treatment tools, then the precision and control of tissue resection is improved, but the device complexity increases
Solution Approach 1:
Multiple motor drives (axial and rotational) are integrated into a unified control system that coordinates their operation. The motor drives are combined in such a way that they work together seamlessly to achieve precise three-dimensional positioning and orientation of treatment tools during tissue resection, maintaining precision while managing system complexity through integrated control.
Solution Approach 2:
The motor drive system is designed to dynamically adjust axial and rotational movements based on real-time surgical requirements. The system can vary speed, torque, and movement patterns during different phases of the procedure, allowing precise control of tissue resection while adapting to changing surgical conditions.
3Reliability
If the system uses contact sensors and controllers for automated stabilization of the cervix, then the stability and safety of the procedure is improved, but the device complexity increases
Solution Approach 1:
Contact sensors are integrated into the stabilizing device to provide real-time feedback on the position and contact force applied to the cervix. The controller receives this feedback and automatically adjusts the stabilizing force and position to maintain optimal cervix stabilization throughout the procedure, improving reliability through closed-loop control.
Solution Approach 2:
The control system is designed to automatically adjust stabilization parameters based on sensor input without requiring constant manual intervention. The system self-regulates the stabilizing device's position and force application, maintaining cervix stability autonomously while reducing the burden on the surgeon.
