Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a distributed processing system with independent control circuits is used to manage firing and closure motors, then control precision and synchronization are improved, but device complexity increases
Solution Approach 1:
The control system is divided into separate control circuits for firing and closure motors, with each circuit independently managing its respective motor. This segmentation allows precise control of each motor while maintaining overall system coordination through defined communication protocols and synchronization mechanisms.
2Manufacturing precision
If real-time adjustments and synchronization are implemented, then tissue treatment motion accuracy is improved, but processing time and computational load increase
Solution Approach 1:
The control circuits implement real-time feedback mechanisms where each control circuit monitors its motor's position and speed, and adjusts control signals accordingly to maintain synchronization. This closed-loop control ensures accurate tissue treatment motion while optimizing processing time through efficient error correction.
3Productivity
If robotic systems with interchangeable shaft assemblies are integrated, then surgical procedure efficiency is improved, but system complexity and cost increase
Solution Approach 1:
The robotic system incorporates interchangeable shaft assemblies that can be attached to a common robotic arm platform, allowing a single system to perform multiple surgical functions. This multi-functionality improves surgical procedure efficiency by enabling different surgical instruments to be used with the same robotic system while managing complexity through standardized interfaces.
