Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual marking and alignment methods are used, then the surgical procedure can be performed with simple equipment, but the precision of bone implant placement deteriorates
Solution Approach 1:
The patent replaces manual mechanical marking and alignment operations with an automated robotic system. The robotic arm executes predefined trajectories to position surgical tools with high precision, substituting human manual operations with automated mechanical control. This resolves the contradiction by achieving high placement precision through automation while managing system complexity through integrated control software and pre-surgical planning.
Solution Approach 2:
The robotic system performs self-positioning and self-alignment through automated control. The system independently executes surgical tasks based on pre-planned trajectories and real-time localization data, reducing reliance on manual intervention. This enables high precision placement while streamlining the operational process despite the sophisticated hardware involved.
2Reliability
If manual operations are performed by the surgeon, then the system is easier to operate, but the reliability of executing the surgical plan deteriorates
Solution Approach 1:
The patent replaces manual surgical operations with automated robotic execution. The robotic arm follows pre-defined trajectories with high accuracy, ensuring reliable execution of the surgical plan. The system integrates localization, trajectory calculation, and automated control to achieve consistent, repeatable results that are more reliable than manual operations, while the control interface is designed to be user-friendly for surgical staff.
3Measurement precision
If a robotic system with automated positioning is used, then the precision of surgical tool placement is improved, but the complexity of the system increases
Solution Approach 1:
The patent implements automated localization and positioning systems that track the surgical tool and robotic arm in real-time. This substitution of manual positioning with automated optical/mechanical tracking achieves high measurement precision. The system complexity is managed through integrated control architectures that coordinate multiple subsystems (localization, trajectory planning, robotic control) into a unified platform.

AI summary
A surgical robotic system for executing a bone implant surgical plan—includes a surgical robot. The surgical robot includes a first robotic arm for manipulating a surgical tool during a surgical procedure at a surgical site. A control unit of the surgical robotic system includes a processor programmed to direct the surgical robot to position the surgical tool. The processor program includes instructions for executing an act of defining the location of the surgical tool with respect to the surgical site. The processor program also includes instructions for executing further acts of moving the surgical tool to a bone located within the surgical site, the location of which being predefined within the surgical plan, and of marking the bone with the surgical tool, the marking corresponding to the position of a bone implant to be implanted in the bone according to the surgical plan.
