Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional needle tips fail to stimulate intercellular connection signals in the skin, limiting collagen and elastic fiber regeneration due to the application of high frequency without mechanical stimulation.
Innovation Solution
A needle tip and patch that apply high frequency while rotating needles or an attachment pad into the skin, inducing twisting and stimulating intercellular connections through skin tissue stretching, with features like a holder, needles, high-frequency application, and a rotation mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high frequency is applied to the skin using conventional needle tips, then heat energy is delivered to induce coagulation necrosis, but intercellular connection signals are not stimulated and collagen regeneration is limited
Solution Approach 1:
The patent combines high-frequency electrical stimulation with mechanical rotation of multiple needles into a single integrated treatment mechanism. The needle tip assembly includes multiple needles arranged in a specific pattern that rotate together while delivering high frequency current, merging electrical and mechanical therapeutic actions into one device operation to enhance collagen regeneration through both thermal and mechanical stimulation pathways
Solution Approach 2:
The needle tip system transitions from a static configuration to a dynamic rotating structure. The multiple needles are mounted on a rotating component that can spin at controlled speeds, allowing the treatment to progress from initial skin penetration through a coordinated twisting motion. This dynamic rotation creates varying mechanical stresses on tissue while maintaining continuous electrical contact, enhancing the regenerative effect beyond what static needles could achieve
2Productivity
If multiple needles are inserted into the skin to stimulate tissues, then coagulation necrosis is induced through heat energy, but the skin twisting effect and intercellular signal stimulation are not achieved
Solution Approach 1:
The needle tip is divided into multiple individual needles (typically 3-6 needles) arranged in a specific geometric pattern around a central axis. Each needle can be independently positioned and controlled, allowing the treatment to affect multiple tissue zones simultaneously. This segmentation enables broader coverage and more comprehensive tissue stimulation compared to a single needle, while the needles work together as a coordinated unit during rotation
Solution Approach 2:
The rotating needle assembly creates periodic mechanical stimulation as it rotates, with each needle passing through the same tissue location at regular intervals. This periodic action delivers repeated mechanical stress cycles to the tissue, enhancing the twisting effect and promoting collagen regeneration through cyclic loading. The rotation can be controlled to achieve specific rotational speeds and durations for optimized therapeutic effect
3Temperature
If only high frequency electrical stimulation is applied, then heat energy is delivered to the skin, but mechanical stretching and twisting of skin tissues do not occur
Solution Approach 1:
The treatment approach combines two different energy modalities: high-frequency electrical energy and mechanical rotational energy. The needle tip system delivers both thermal energy through resistive heating and mechanical energy through tissue twisting, creating a composite treatment effect. This dual-mode energy delivery addresses multiple regenerative pathways simultaneously, combining the coagulation and heating effects of RF with the mechanical stimulation effects of rotation to enhance overall tissue regeneration
