Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skin treatment techniques for rejuvenation, such as fractional treatments, often require complex systems like electrical motors and lack seamless mechanisms for electrode insertion and withdrawal, posing safety and operational challenges.
Innovation Solution
The use of manually driven elongated electrodes configured for controlled insertion and automatic withdrawal, with a movement mechanism enabling safe and efficient tissue treatment, allowing for monopolar, bipolar, or multipolar modes of electrical energy delivery for ablation or coagulation, and a controller for real-time parameter adjustment based on insertion depth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If complex systems like electrical motors are used for electrode insertion, then automated operation is achieved, but device complexity increases
Solution Approach 1:
The patent replaces complex electrical motors with a simple manual mechanical pushing motion. The practitioner manually pushes the electrode assembly into the tissue, eliminating the need for automated motor systems while maintaining effective treatment delivery. This substitution resolves the contradiction by achieving adequate automation through simple manual mechanics rather than complex automated systems.
2Device complexity
If manual electrode insertion is used, then device complexity is reduced, but insertion depth control precision deteriorates
Solution Approach 1:
The patent incorporates pre-set depth markers or stops on the electrode assembly that indicate predetermined insertion depths. Before the treatment begins, these depth indicators are configured to automatically limit how far the electrode can be inserted, ensuring consistent and precise depth control without requiring complex automated positioning systems. This preliminary configuration resolves the contradiction by maintaining simplicity while achieving precision through pre-established depth limits.
3Ease of operation
If electrodes are left exposed during treatment, then ease of operation is improved, but safety deteriorates due to potential injury
Solution Approach 1:
The patent inverts the traditional approach by having the electrode assembly automatically retract or be withdrawn after treatment completion. Instead of requiring manual retrieval of exposed electrodes, the system is designed so that the electrode naturally returns to a retracted position or is automatically pulled out, eliminating the safety hazard of exposed electrodes while maintaining ease of operation during the treatment itself. This inversion resolves the contradiction by reversing the sequence of exposure and retraction.
4Object-affected harmful factors
If automated electrode retrieval systems are used, then safety is improved, but device complexity increases
Solution Approach 1:
The patent employs a self-service mechanism where the electrode assembly automatically retracts or is withdrawn through its own structural design after treatment. The system uses the treatment mechanism itself to facilitate electrode retrieval, eliminating the need for separate automated retrieval systems. This self-service approach resolves the contradiction by achieving safety through the treatment system's inherent design rather than adding complex dedicated retrieval mechanisms.

AI summary
A tissue treatment device and system comprising a first stage having at least one elongated electrode with a length extending distally from the first stage and configured for receiving an electrical current signal from an electrical current source and for being inserted into the tissue to deliver the electrical current signal to the tissue thereby applying a treatment to the tissue. A second stage located distally to the first stage at a distance being at least equal to the length of the at least one elongated electrode, the second stage configured for being placed on surface of the tissue. A movement mechanism configured to: enable proximal displacement of the second stage to reveal a specific length of the at least one elongated electrode, under application of an external proximal force on the second stage and returning the second stage to its default location covering the distal end of the at least one elongated electrode, once the proximal force ends.
