Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If modular components are integrated with a communication bus and backplane, then device complexity is reduced and ease of operation is improved, but manufacturing precision and assembly reliability require higher standards
Solution Approach 1:
The surgical system is divided into modular components (energy generators, smoke evacuation module, etc.) that can be independently manufactured and assembled. Each module connects to the communication bus and power backplane through standardized interfaces, reducing overall system complexity while enabling reliable assembly through modular design
Solution Approach 2:
The communication bus and power backplane serve as universal interfaces that multiple different modules can connect to. This standardized universal interface reduces the need for custom wiring and integration for each module, simplifying the overall system while maintaining reliability through consistent connection protocols
2Ease of operation
If multiple power and data lines are integrated into modules, then ease of operation is improved, but device complexity and assembly difficulty increase
Solution Approach 1:
Power lines and data communication lines are merged into a single integrated backplane structure. Multiple modules share this common backplane for both power distribution and data communication, eliminating the need for separate wiring harnesses for each function and significantly reducing wiring complexity
Solution Approach 2:
The communication bus and power backplane act as intermediary structures that mediate between the external power source and multiple modules. Instead of directly connecting each module to power and data sources, the backplane serves as an intermediate distribution network, simplifying connections

AI summary
Surgical instruments and system and methods for using surgical instruments are disclosed. A surgical instrument comprises an end effector comprising an ultrasonic blade and clamp arm, an ultrasonic transducer, and a control circuit. The ultrasonic transducer ultrasonically oscillates the ultrasonic blade in response to a drive signal from a generator. The end effector receives electrosurgical energy to weld tissue. The control circuit determines a resonant frequency measure indicative of a thermally induced change in resonant frequency and a electrical continuity measure; calculates a weld focal point based on the determined measures, controls closure of the clamp arm to vary a pressure applied by the clamp arm to provide a threshold control pressure to the tissue loaded into the end effector, and maintains a gap between the ultrasonic blade and clamp arm at a point proximal to the proximal end of the tissue. Pressure is varied based on corresponding weld focal point.
