RF Electrode Subarray Sequencing for Lower-Pain Skin Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radio frequency electrode arrays cause larger instantaneous treatment size and longer treatment time, leading to significant pain and poor user experience due to factors like duration, area of action, and power of RF energy delivery.
Innovation Solution
The RF electrode array control device employs a subarray determination module to generate a target sequence for RF electrode subarrays, allowing sequential activation with overlapping output periods to reduce treatment area and time, using a control module to manage RF energy delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the RF electrode array delivers RF energy to the entire treatment area simultaneously, then the treatment coverage is maximized, but the instantaneous treatment size increases causing larger pain reaction
Solution Approach 1:
The RF electrode array is divided into multiple subarrays that can be activated independently. The control module activates subarrays sequentially in a predetermined sequence, ensuring that only one subarray delivers RF energy to a specific skin region at any given time. This segmentation reduces the instantaneous treatment size and corresponding pain reaction while maintaining comprehensive treatment coverage through sequential activation of all subarrays.
2Loss of time
If the RF electrode array activates all subarrays simultaneously, then the treatment time is shortened, but the treatment area covered at any moment increases causing longer perceived treatment duration and more pain
Solution Approach 1:
The control module implements periodic sequential activation of RF electrode subarrays according to a predetermined sequence. Each subarray is activated in turn for a specific duration, then deactivated while the next subarray is activated. This periodic action ensures that the entire treatment area is covered systematically over time, reducing the instantaneous treatment size and pain reaction at any moment while completing the full treatment protocol.
3Productivity
If higher RF power is used to achieve treatment effects faster, then the treatment time is reduced, but the pain reaction and side effects increase
Solution Approach 1:
The RF electrode array is segmented into multiple subarrays that can be activated independently. The control module activates subarrays sequentially, ensuring that only one subarray delivers RF energy to a specific skin region at any given time. This segmentation allows the system to deliver RF energy at appropriate power levels to each subarray without causing excessive pain or side effects, while maintaining treatment efficiency through systematic coverage of the entire treatment area.
