Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional medical instruments are used in robotically assisted surgeries, then the clinician can perform surgical functions, but the system requires awkward arm motions and is not easily controllable by a single user
Solution Approach 1:
The robotic system is divided into multiple independent robotic arms, each capable of performing specific surgical functions. This segmentation allows each arm to be controlled independently, simplifying the control interface for a single user while maintaining the ability to perform complex multi-step surgical procedures through coordinated arm movements.
Solution Approach 2:
The robotic system integrates multiple surgical functions into a single unified platform, including cutting, coagulation, grasping, and imaging capabilities. This multi-functionality eliminates the need for multiple separate instruments and reduces the complexity of coordinating multiple devices, allowing a single user to control all functions through one integrated control interface.
2Productivity
If traditional hysterectomy procedures are performed manually, then the procedure can be completed, but it requires multiple clinicians and awkward arm motions
Solution Approach 1:
The robotic system performs many surgical tasks autonomously based on pre-programmed sequences and real-time feedback from sensors. The robotic arms can automatically position themselves, adjust their movements based on tissue resistance, and coordinate their actions without requiring constant manual intervention from multiple clinicians, thereby improving procedural efficiency while maintaining ease of operation.
Solution Approach 2:
The system incorporates real-time feedback mechanisms including force sensors, position encoders, and visual feedback displays that provide the operator with information about the current state of the surgical field. This feedback loop allows the robotic system to automatically adjust its actions and provides the operator with enhanced situational awareness, improving both efficiency and ease of operation.
3Manufacturing precision
If a robotic system with multiple arms is used, then surgical precision is improved, but the system becomes more complex and harder to control
Solution Approach 1:
The system merges the control of multiple robotic arms into a single unified control interface that processes commands and coordinates movements of all arms simultaneously. This consolidation maintains surgical precision by ensuring coordinated action of multiple arms while reducing the perceived complexity for the operator by providing a single point of control rather than multiple separate control systems.

AI summary
An apparatus includes a modular colpotomy cup component and a modular shaft component. The modular colpotomy cup component includes a proximal base, an elongated sleeve, an expanding member, and a colpotomy cup. The proximal base is configured to couple to a distal end of a head of a robotic arm. The modular shaft component includes a coupling body and an elongated shaft. The coupling body is configured to couple to the head of the robotic arm such that the modular shaft component and the modular colpotomy cup component are attached to each other via the head of the robotic arm. The elongated shaft extends distally from the coupling body and is configured to be inserted through the opening of the proximal base such that the coupling body is configured to couple to the head of the robotic arm.
