Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing electrosurgical generators are used, then the device structure is simple, but the array of bipolar energy characteristics is limited
Solution Approach 1:
The electrosurgical generator is designed to provide multiple types of energy output (monopolar and bipolar) through a single device. The system can switch between different energy delivery modes and configurations, allowing one generator to serve multiple surgical procedures and applications, thereby expanding the array of bipolar energy characteristics without requiring separate dedicated devices for each function.
Solution Approach 2:
The generator incorporates dynamic control capabilities that allow real-time adjustment of energy characteristics including frequency, amplitude, pulse duration, and duty cycle. The system can dynamically switch between monopolar and bipolar modes, and adjust energy parameters during procedures to match varying surgical requirements, providing adaptability while maintaining a unified device structure.
2Use of energy by moving object
If monopolar energy is received first, then the energy storage device can be charged, but the bipolar energy control is delayed
Solution Approach 1:
The system performs preliminary charging of the energy storage device using monopolar energy during initial connection and setup phases. This preliminary action ensures that sufficient energy is stored in advance before bipolar energy delivery is required, eliminating delays when bipolar mode needs to be activated during surgery. The switch automatically transitions to bipolar mode once adequate energy reserves are established.
Solution Approach 2:
The generator maintains continuous energy delivery capability by seamlessly transitioning between monopolar charging mode and bipolar delivery mode. The system ensures uninterrupted useful action by keeping the energy storage device charged through monopolar input while ready to immediately provide bipolar output when needed, maintaining continuous operational readiness without idle time or delays.
