Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple electrodes are moved and positioned independently within a body, then positioning precision and treatment effectiveness are improved, but device complexity and operational difficulty increase
Solution Approach 1:
The device divides the electrode positioning system into separate actuators for each electrode. Each actuator can be independently controlled to move its corresponding electrode to a desired position, enabling precise independent positioning while managing complexity through modular design
Solution Approach 2:
The system employs dynamic control mechanisms that allow real-time adjustment of electrode positions. The actuators can be activated selectively based on treatment requirements, enabling flexible and adaptive positioning during electrosurgical procedures
2Manufacturing precision
If multiple electrodes are positioned independently, then treatment accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
By providing separate actuators for each electrode, the system allows operators to control each electrode independently through dedicated interfaces, simplifying the operation of complex multi-electrode positioning while maintaining high placement accuracy
Solution Approach 2:
The control mechanism incorporates feedback systems that monitor electrode positions and provide real-time information to the operator. This enables precise electrode placement while reducing operational difficulty through intuitive control and visual/auditory feedback

Disclosed embodiments include apparatuses, systems, and methods for positioning electrodes within a body. In an illustrative embodiment, an apparatus for slidably moving multiple features relative to a sheath insertable into a body and positionable relative to a reference point includes a primary actuator configured to move a primary electrode to a first position. A secondary actuator is configured to move a secondary electrode to a second position. A shrouding device is configured to selectively prevent access to the secondary actuator until the primary actuator has been manipulated to extend the primary electrode to the first position.
