Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice-control capability is added to electrosurgical systems, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The speech recognition module is integrated into the electrosurgical generator, allowing the same device to perform both traditional electrosurgical functions and voice-controlled operations. The controller is configured to receive inputs from both traditional interfaces and the speech recognition module, enabling multi-functionality without requiring separate dedicated voice-control equipment.
Solution Approach 2:
The speech recognition module acts as an intermediary between the surgeon's voice commands and the electrosurgical system's control functions. It converts spoken commands into encrypted digital signals that the controller can process, bridging the gap between natural language input and machine execution while maintaining system security through encryption.
2Reliability
If voice commands are encrypted and validated, then reliability is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary validation of voice commands against a library of predefined valid commands before execution. The controller checks whether the decrypted command matches any authorized command in its library, preventing unauthorized or erroneous operations. This preliminary validation ensures reliability by filtering out invalid commands before they can cause harmful effects.
Solution Approach 2:
The system provides feedback to the user regarding command recognition and validation status. When a voice command is received, the system processes it through encryption and decryption, then validates it against the command library, providing feedback on whether the command was successfully recognized and executed or if it was invalid or unrecognized.
3Ease of operation
If wireless communication is implemented for voice commands, then ease of operation is improved, but loss of information increases
Solution Approach 1:
The system performs preliminary encryption of voice commands before wireless transmission. By encrypting the commands prior to sending them over the wireless communication channel, the system protects the integrity and confidentiality of the transmitted information, preventing loss or corruption of data during transmission.
