Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single RF amplifier is used to treat multiple locations, then device complexity is reduced, but control precision and safety deteriorate due to inability to independently regulate energy delivery to each location
Solution Approach 1:
The system divides the RF amplification function into multiple independent channels, with each channel having its own RF amplifier. This segmentation allows independent control of RF energy delivery to each treatment location, resolving the contradiction between device complexity and control precision.
2Ease of operation
If non-simultaneous time-sliced energy delivery is used from a single RF amplifier, then independent control loops become possible, but patient safety deteriorates due to risk of unwanted neuromuscular stimulation
Solution Approach 1:
The system assigns a dedicated RF amplifier to each channel, eliminating the need for time-sliced delivery. Each channel operates simultaneously with its own independent control loop, providing both independent control capability and continuous safe energy delivery without interruption that could cause neuromuscular stimulation.
Solution Approach 2:
By using multiple simultaneous RF amplifiers instead of time-sliced delivery, the system maintains continuous RF energy delivery to all treatment locations. This continuity eliminates the off-periods in time-sliced delivery that can trigger unwanted neuromuscular stimulation, while still allowing independent control of each channel.
3Productivity
If simultaneous energy delivery from a single RF amplifier is used, then treatment efficiency is improved, but control precision deteriorates due to shared amplifier limitations
Solution Approach 1:
The system segments the RF amplification function across multiple independent amplifiers, one per channel. This allows simultaneous energy delivery to multiple locations while maintaining precise independent control of power levels at each location, resolving the contradiction between treatment efficiency and control precision.
4Device complexity
If mechanical relays are used to switch RF output between channels, then a single RF amplifier can serve multiple channels, but reliability deteriorates due to switching interruptions and settlement requirements
Solution Approach 1:
The system eliminates mechanical relays by assigning a dedicated RF amplifier to each channel. Each amplifier continuously drives its channel without switching interruptions, eliminating reliability issues associated with relay contact settlement and RF output interruptions while maintaining the ability to serve multiple channels simultaneously.
