Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID technology is integrated into surgical instruments to identify and authenticate components, then reliability and safety are improved, but device complexity increases
Solution Approach 1:
The RFID identification system is segmented into multiple independent RFID chips embedded within different surgical components (e.g., staple cartridges, cutting elements). Each chip contains specific authentication data, allowing the control circuit to verify component authenticity and compatibility through individual chip readings without requiring a single complex identification mechanism.
Solution Approach 2:
A control circuit acts as an intermediary between the RFID chips and the surgical instrument's control system. The control circuit reads authentication data from multiple RFID chips, processes the information, and determines component compatibility and authenticity, thereby simplifying the overall system architecture while maintaining high reliability.
2Measurement precision
If multiple RFID chips are used to identify components, then measurement precision of component authentication is improved, but device complexity increases
Solution Approach 1:
Authentication information is segmented across multiple RFID chips embedded in different surgical components. Each chip stores specific authentication data (e.g., component type, compatibility information, serial numbers), allowing the system to verify authenticity through multiple independent data points rather than relying on a single complex authentication mechanism.
Solution Approach 2:
The control circuit reads authentication data from multiple RFID chips and processes the information to determine component compatibility and authenticity. The system uses feedback from multiple chip readings to verify consistency and accuracy of authentication data, thereby improving measurement precision while managing complexity through systematic data processing.
3Productivity
If real-time monitoring of operational parameters is implemented, then productivity is improved, but use of energy increases
Solution Approach 1:
The control circuit performs periodic sampling of operational parameters from RFID chips and sensor data rather than continuous monitoring. The system reads authentication data and monitors component status at specific intervals during surgical procedures, maintaining productivity through timely updates while reducing energy consumption by avoiding constant data acquisition and processing.

AI summary
A method of operating a surgical assembly is disclosed. The method includes receiving a first input from a first RFID scanner indicative of a first information stored in a first RFID chip of a first modular component of the surgical assembly, receiving a second input from a second RFID scanner indicative of a second information stored in a second RFID chip of a second modular component of the surgical assembly, determining an operational parameter of a motor of the surgical assembly based on the first input and the second input, and causing the motor to effect a tissue treatment motion of the first modular component.
