Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional control switches are used in surgical instruments, then the device structure remains simple, but the precision and customization capability of surgical procedures is limited
Solution Approach 1:
The patent implements a feedback mechanism where the control switch system monitors its own operation and provides real-time diagnostic information to the processor. The processor receives signals from the control switch and adjusts operational parameters accordingly, creating a closed-loop control system that enhances precision while managing complexity through intelligent control algorithms.
Solution Approach 2:
The patent replaces traditional mechanical control switches with an electronic control system that includes a control switch coupled to a processor. This substitution allows for more precise control through electronic signaling and software-based threshold adjustments, while the self-diagnosing capability reduces the need for complex mechanical diagnostic mechanisms.
2Adaptability or versatility
If fixed threshold levels are used for control switch displacement, then the device structure remains simple, but the adaptability to different surgical procedures and tissue types is reduced
Solution Approach 1:
The patent implements dynamic threshold levels that can be adjusted based on the specific surgical procedure and tissue type being treated. The processor dynamically modifies the displacement thresholds of the control switch to optimize performance for different surgical scenarios, transforming a static control system into an adaptive one that responds to varying surgical requirements.
Solution Approach 2:
The patent changes the operational parameters of the control switch by allowing the processor to adjust displacement thresholds based on the measured degree of displacement and energy delivery. This parameter adjustment enables the same physical control switch to adapt to different surgical procedures, tissue types, and energy levels without requiring hardware modifications.
3Reliability
If real-time monitoring of control switch operation is implemented, then the precision and customization of surgical procedures is enhanced, but the energy consumption and system complexity increase
Solution Approach 1:
The patent implements a self-service monitoring system where the control switch automatically diagnoses its own operation and provides diagnostic information to the processor without requiring external monitoring equipment. The system self-regulates by comparing measured displacement against threshold levels and automatically adjusts operation accordingly, reducing the need for continuous high-energy monitoring while maintaining reliability.

AI summary
Provided is a system and medical device that includes self diagnosing control switches. The control switch may be slidable within a slot in order to control activation of some function of the medical device. Due to natural wear and tear of movement of a control switch, the distances along the sliding slot that correspond to how much energy is used for the function may need to be adjusted over time in order to reflect the changing physical attributes of the actuator mechanism. The self diagnosing control switches of the present disclosures may be configured to automatically adjust for these thresholds using, for example, Hall effect sensors and magnets. In addition, in some cases, the self diagnosing control switches may be capable of indicating external influences on the controls, as well as predict a time until replacement is needed.
