Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple specialized robotic arm systems are used to accommodate different surgical procedures, then the system can perform a wide range of surgical procedures, but the capital cost increases and the device complexity increases
Solution Approach 1:
The robotic arm system is designed with universal mounting capabilities that allow the same robotic arm to be attached to different mounting structures (column, rail, or free-standing) and reconfigured for various surgical procedures. This multi-functionality enables a single system to replace multiple specialized systems, reducing capital cost and device complexity while maintaining versatility across different surgical applications
2Adaptability or versatility
If a robotic arm system is manually reconfigured for each surgical procedure, then the system can adapt to different surgical needs, but the time consumption increases and the physical demand on physicians increases
Solution Approach 1:
The mounting structures (column, rail, or free-standing) are designed to be dynamically reconfigurable, allowing the robotic arm to be easily attached, detached, and repositioned between different mounting locations. This dynamic design enables quick adaptation to different surgical procedures without requiring time-consuming manual reconfiguration, reducing the time loss and physical demand on physicians while maintaining procedural versatility

AI summary
A surgical robotics system with robotic arms is configurable to perform a variety of surgical procedures. The surgical robotics system includes a table, column, base, and robotic arms that are either column-mounted, rail-mounted, or mounted on a separate unit. In a column-mounted configuration, the column includes column rings that translate vertically and rotate about the column. The robotic arms are attached to the column rings. In a rail-mounted configuration, the base includes base rails that translate along the base. The robotic arms are attached to the base rails. In both configurations, the robotic arms move independently from each other and include a multiple arm segments. Each arm segment provides an additional degree of freedom to the robotic arm. Thus, the surgical robotics system may position the robotic arms into numerous configurations to access different parts of a patient's body.
