Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple surgical stages are executed sequentially as traditionally done, then each stage can be completed with dedicated control, but the overall surgical procedure time increases and procedural complexity increases
Solution Approach 1:
The patent combines multiple surgical stages into a single unified stage by merging their control boundaries. The system determines whether stages can be combined by checking if their control boundaries can be unified, and if so, executes them as one stage rather than sequentially, thereby reducing overall procedure time while maintaining surgical precision through integrated control.
Solution Approach 2:
The system dynamically adjusts the number of surgical stages based on real-time analysis of control boundary compatibility. Rather than following a fixed sequential process, the system evaluates whether stages can be merged and adapts the surgical plan accordingly, optimizing the procedure flow to reduce time loss without compromising precision.
2Reliability
If multiple surgical stages are executed sequentially, then each stage can be controlled independently, but the procedural complexity increases
Solution Approach 1:
The patent reduces procedural complexity by merging control boundaries of compatible surgical stages. The system analyzes whether stages can share a unified control boundary, and when they can, combines them into a single stage, thereby simplifying the overall procedure while maintaining control accuracy through the unified boundary system.
Solution Approach 2:
The system creates a universal control boundary framework that can serve multiple surgical stages simultaneously. By designing control boundaries that can be shared across different stages, the system reduces procedural complexity while maintaining the reliability needed for accurate control of each surgical operation.
3Productivity
If surgical stages are combined into a unified stage, then procedural efficiency improves and complexity reduces, but the requirement for precise control boundary determination increases
Solution Approach 1:
The system performs self-service by automatically determining control boundary compatibility and making merger decisions without requiring manual analysis. The computer system autonomously evaluates whether surgical stages can be combined based on their control boundaries, thereby improving surgical efficiency while managing the complexity of boundary analysis through automation.
Solution Approach 2:
The system uses feedback mechanisms to determine whether control boundaries can be unified. By analyzing the compatibility of control boundaries and providing feedback on merger eligibility, the system enables efficient stage combination while managing the analytical complexity through structured evaluation criteria.

AI summary
A robotically-assisted surgical system includes a robot and a computer. The computer is programmed to provide a user with an option to combine a first cutting stage of a surgical plan with a second cutting stage of the surgical plan in response to determining that the first cutting stage is eligible for combination with the second cutting stage by comparing first characteristics of the first cutting stage with second characteristics of the second cutting stage. The computer is also programmed to, absent selection of the option, control the robot to provide the first cutting stage and the second cutting stage sequentially and also to, in response to user selection of the option, control the robot to provide a unified cutting stage based on the first cutting stage and the second cutting stage.
