Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If rigid tools are inserted through access ports for minimally invasive procedures, then patient trauma is reduced, but mobility and operational capability are restricted
Solution Approach 1:
The robotic system is divided into multiple segments including a base station, robotic arms, and end effectors that can be independently controlled and positioned. This segmentation allows the system to navigate complex anatomical spaces while maintaining minimal patient trauma through small access ports.
Solution Approach 2:
The robotic arms and end effectors incorporate dynamic positioning capabilities with multiple degrees of freedom, allowing real-time adjustment of position and orientation. This dynamic control enables complex maneuvers within confined spaces while maintaining minimal invasiveness.
2Device complexity
If traditional laparoscopic tools are used, then procedure simplicity is maintained, but visual feedback and sensory capabilities are limited
Solution Approach 1:
The robotic end effectors are designed with multi-functionality, capable of performing multiple surgical tasks such as grasping, cutting, suturing, and cauterizing. Integrated sensors and imaging capabilities provide comprehensive visual feedback, eliminating information loss while maintaining procedural versatility.
Solution Approach 2:
The system incorporates multiple sensors including force sensors, position sensors, and imaging systems that provide real-time feedback to the operator. This feedback loop enables precise control and enhanced situational awareness without complicating the overall procedure.
3Adaptability or versatility
If robotic systems are made larger with more capabilities, then functionality is improved, but availability and cost increase
Solution Approach 1:
The robotic components are designed with nested structures where end effectors can be stored within or attached to robotic arms, and multiple arms can be compactly positioned around a central base. This nesting reduces the overall system footprint and manufacturing complexity while maintaining full functionality.
Solution Approach 2:
Advanced capabilities such as high-precision sensors, imaging systems, and sophisticated actuators are concentrated at the end effectors where they are most needed, rather than distributing them throughout the entire system. This localized approach reduces overall system cost while maintaining high functionality at the operational interface.
4Adaptability or versatility
If modular components are used for the robotic device, then adaptability and functionality are improved, but device complexity increases
Solution Approach 1:
The robotic system is divided into standardized modular components including interchangeable end effectors, robotic arms, and base stations. Each module features standardized interfaces and mounting mechanisms, allowing easy reconfiguration without increasing overall system complexity.
Solution Approach 2:
The modular components are designed with universal interfaces and standardized connection protocols, allowing the same base station and control system to operate with multiple different end effector types. This universality enables adaptability while reducing the complexity of managing multiple complete systems.
