Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual drug delivery techniques are used, then ease of operation is maintained, but manufacturing precision and measurement precision deteriorate
Solution Approach 1:
The system automatically calculates and adjusts infusion rates based on real-time withdrawal rate data from the robotic device, eliminating the need for manual rate determination by physicians. The processor continuously monitors withdrawal rates and autonomously modifies infusion parameters to maintain optimal delivery rates throughout the procedure.
Solution Approach 2:
The patent replaces manual mechanical control of infusion devices with an automated computational system. The processor-based system substitutes human judgment and manual adjustment with algorithmic calculation of infusion rates based on measured withdrawal rates, thereby improving precision while managing complexity through software automation.
2Productivity
If fixed infusion rates are used, then ease of operation is maintained, but productivity and treatment effectiveness deteriorate
Solution Approach 1:
The system transitions from static fixed infusion rates to dynamic rate adjustment based on real-time conditions. As the robotic device withdraws the cannula at varying speeds, the infusion rate automatically adapts to maintain consistent drug delivery relative to the changing withdrawal rate, thereby improving treatment efficiency without requiring manual intervention at each stage.
Solution Approach 2:
The system implements a feedback loop where the processor continuously monitors the withdrawal rate of the infusion device and uses this information to adjust the infusion rate accordingly. This closed-loop control ensures that drug delivery remains effective throughout the procedure while automatically adapting to changing conditions, thereby improving productivity without increasing operational complexity for the user.
3Measurement precision
If manual expertise is required, then adaptability to different cases is maintained, but measurement precision and consistency deteriorate
Solution Approach 1:
The patent replaces manual measurement of withdrawal rates with automated sensor-based measurement systems. The robotic device's controlled movement and integrated sensors provide precise, consistent measurement of withdrawal rates without relying on human observation or estimation, thereby improving measurement precision while maintaining versatility through programmable adaptation to different procedural requirements.

AI summary
A system includes a processor and a memory storing instructions thereon. The instructions, when executed by the processor, cause the processor to: infuse a substance into a target object, via an infusion device, according to a first flow rate; set a second flow rate associated with infusing the substance into the target object, based on a withdrawal rate of the infusion device from the target object; and infuse the substance into the target object based on the second flow rate.
