Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrosurgical instruments are used to cut and coagulate tissue, then surgical effectiveness is improved, but tissue and blood sticking occurs on the electrode
Solution Approach 1:
Irrigation fluid is supplied to the surgical electrode before electrosurgical operations begin, creating a protective layer that prevents tissue and blood from adhering to the electrode surface during the procedure
Solution Approach 2:
Irrigation fluid acts as an intermediary substance between the surgical electrode and the tissue/blood, preventing direct contact and adhesion while allowing the electrode to perform its cutting and coagulation functions
2Productivity
If irrigation fluid flow rate is increased to prevent sticking, then operational efficiency is improved, but fluid consumption increases
Solution Approach 1:
A flow sensor continuously monitors the irrigation fluid flow rate and provides feedback to the logic controller, which automatically adjusts the flow rate to maintain optimal conditions while minimizing fluid consumption
Solution Approach 2:
The irrigation fluid flow rate is made dynamically adjustable rather than fixed, allowing the system to optimize between preventing sticking and reducing fluid consumption based on real-time surgical conditions
3Object-generated harmful factors
If manual monitoring and adjustment of irrigation fluid is performed, then sticking prevention is achieved, but operational complexity increases
Solution Approach 1:
The system performs self-monitoring and self-adjustment of irrigation fluid flow rate through automated sensors and logic controllers, eliminating the need for manual intervention while maintaining effective sticking prevention
Solution Approach 2:
Automated feedback loops using flow sensors and logic controllers continuously monitor and adjust irrigation fluid parameters, replacing manual monitoring with an autonomous control system that reduces operational complexity
