Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If robotic systems are used to assist in MIS procedures, then surgical precision and degrees of freedom are improved, but the cost of manufacturing increases significantly
Solution Approach 1:
The robotic system is divided into modular components: a handle assembly that can be manually operated, a separate motor assembly, and an adapter that couples them together. This segmentation allows the expensive robotic components (motor, adapter with electronics) to be optional add-ons rather than mandatory integrated systems, reducing overall manufacturing cost while preserving precision capabilities when needed.
Solution Approach 2:
The handle assembly is designed to function in multiple modes: it can be operated manually without any robotic components, or coupled with the adapter and motor assembly for automated robotic control. This multi-functionality allows a single base device to serve both cost-sensitive applications (manual operation) and precision-sensitive applications (robotic operation), addressing both ends of the cost-precision spectrum.
2Ease of operation
If robotic systems are used to maintain natural eye-hand axis and provide degrees of freedom, then surgical dexterity is improved, but direct force feedback to the surgeon is lost
Solution Approach 1:
The system dynamically switches between manual and robotic modes based on surgical needs. When force feedback is required, the surgeon uses manual mode with direct mechanical contact. When surgical dexterity and automated precision are required, the robotic mode engages. This dynamic adaptability allows the system to provide both force feedback and enhanced dexterity at different times during the procedure.
Solution Approach 2:
The adapter assembly serves as an intermediary between the manual handle and the robotic motor system. It includes mechanical coupling elements that can transmit forces when in manual mode, and electrical coupling elements that enable robotic control when engaged. This intermediary structure facilitates the transition between force-feedback manual operation and precision robotic operation without compromising either mode's effectiveness.
