Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple manipulator assemblies are used to support and control the surgical module, then the control precision and deployment capability of surgical tools are improved, but the device complexity increases
Solution Approach 1:
The surgical system is divided into multiple independent manipulator assemblies, each capable of supporting and controlling the surgical module. This segmentation allows for distributed control functions, where each manipulator can be independently controlled to perform specific surgical tasks, thereby improving overall control precision while maintaining manageable complexity through modular design
Solution Approach 2:
The surgical module is designed with universal interfaces that can be supported and controlled by different manipulator assemblies. The actuating mechanisms are configured to work with multiple manipulators, allowing the same surgical module to be controlled by different manipulators depending on the surgical requirements, thus improving versatility without proportionally increasing complexity
2Productivity
If actuating mechanisms of manipulators are integrated with actuating mechanisms of surgical tools, then the operation effectiveness is improved, but the device complexity increases
Solution Approach 1:
The actuating mechanisms of the manipulators are integrated with the actuating mechanisms of the surgical tools through the surgical module. This merging allows for coordinated control where the manipulator's actuating mechanisms directly influence the surgical tool's operation, improving operation effectiveness by reducing the number of independent control systems and enabling synchronized movement and positioning
Solution Approach 2:
The surgical module serves as an intermediary between the manipulator assemblies and the surgical tools. It contains actuating mechanisms that receive control signals from the manipulators and transmit them to the surgical tools, facilitating integrated control while providing a buffer that manages the complexity of direct manipulation-tool integration
3Adaptability or versatility
If removably attached manipulator assemblies are used, then the adaptability and ease of deployment are improved, but the connection reliability may be reduced
Solution Approach 1:
The connection between manipulator assemblies and the surgical module is designed to be dynamic rather than static. The removable attachment mechanism allows the system to transition between different operational configurations, enabling the surgical module to be attached to or detached from different manipulators based on surgical requirements, thus improving adaptability while maintaining reliability through controlled dynamic connections
Solution Approach 2:
The attachment mechanisms are designed as disposable or easily replaceable components that ensure reliable connections during each surgical procedure. By using standardized, pre-tested attachment interfaces that can be replaced if needed, the system maintains high connection reliability while allowing for flexible reconfiguration and adaptation to different surgical scenarios

AI summary
A surgical module is supported by manipulators that are removably attached to the surgical module. The surgical module may enable operation of surgical tools by providing an integration between actuating mechanisms of the manipulators and actuating mechanisms of the surgical tools. Alternatively or additionally, the surgical module may enable operation of the surgical tools by providing physical access for deploying surgical tools that are operatively connected to the manipulators.
