Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If rigid tools are used for minimally invasive surgery, then the surgical procedure can be performed through access ports, but mobility is restricted
Solution Approach 1:
The robotic surgical device is divided into multiple segments including a support component, a robotic arm, and an end effector. The support component is disposed through the access port while the robotic arm and end effector are positioned within the body cavity, allowing independent movement and positioning of each segment to achieve enhanced mobility without requiring multiple access ports
Solution Approach 2:
The robotic arm provides six degrees of freedom for positioning the end effector, adding multiple dimensional movements beyond the simple linear insertion through the access port. This enables complex maneuvers and orientations within the body cavity while maintaining the minimally invasive single-port approach
2Measurement precision
If robotic systems are used to improve surgical capabilities, then precision and dexterity are enhanced, but the system size and cost increase significantly
Solution Approach 1:
The robotic arm is positioned within the body cavity through a single access port, with the end effector nested at the distal end of the robotic arm. This nested configuration allows the compact robotic system to achieve high precision within the constrained surgical space without requiring a large external system footprint
Solution Approach 2:
The robotic device incorporates actuators and sensors that enable precise control and feedback, replacing purely mechanical manual manipulation with automated control systems. This substitution provides enhanced surgical precision and dexterity while maintaining a compact form factor through intelligent control rather than oversized mechanical components
3Object-affected harmful factors
If minimally invasive procedures are used to reduce patient trauma, then incision size is reduced, but visual feedback and mobility are limited
Solution Approach 1:
The robotic surgical device incorporates sensors that provide real-time feedback on the position and orientation of the end effector within the body cavity. This feedback mechanism enables the system to maintain precise control and awareness of the surgical environment despite the minimally invasive single-port access, compensating for the limited visual feedback through tactile and positional sensing
