Solution Overview
Problem
Conventional skin anti-aging treatments require frequent sessions, consume large amounts of high-priced liquid drugs, and may cause adverse effects due to indirect high frequency wave application and manual injection methods.
Innovation Solution
A multi-needle device that applies a high frequency wave to the skin before injecting a liquid drug, using a bipolar configuration with a first and second electrode to activate skin cells and tissues, minimizing drug consumption and improving efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional manual injection methods are used, then the liquid drug can be injected into the skin, but large amounts of high-priced liquid drug are consumed
Solution Approach 1:
The patent applies high frequency waves to the skin before injecting the liquid drug to pre-activate skin cells and tissues. This preliminary action prepares the target tissue to better absorb and respond to the subsequently injected drug, thereby improving treatment efficacy while reducing the total amount of drug needed.
Solution Approach 2:
The patent replaces conventional manual injection with an automated injection device that integrates high frequency wave generation and precise drug delivery. This substitution enables controlled, minimal-dose injection while simultaneously applying activating energy to enhance drug effectiveness.
2Reliability
If indirect high frequency wave application through epidermis layer is used, then the treatment can be performed, but the effect on dermis layer is not large
Solution Approach 1:
The patent segments the treatment process into two distinct phases: first applying high frequency waves to activate skin tissues, then injecting the liquid drug. This segmentation allows each treatment modality to work optimally - the high frequency wave penetrates to activate dermal tissues, and the injected drug is delivered directly to the activated target area for maximum effect.
Solution Approach 2:
The patent merges high frequency wave therapy with liquid drug injection into a single integrated treatment system. The multi-needle device combines both high frequency wave electrodes and drug delivery channels, allowing simultaneous or sequential application of energy activation and pharmacological treatment for enhanced therapeutic effect.
3Duration of action of stationary object
If conventional massage therapy is used, then skin nutrients can be supplied to epidermis layer, but regular treatments are required and cost is high
Solution Approach 1:
The patent uses high frequency waves as an intermediary energy form to activate skin cells and enhance their metabolic activity. This activation creates a state where skin tissues can better utilize and retain the injected nutrients, extending the duration of treatment effect and reducing the frequency of required sessions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The multi-needle device enhances the absorption and efficacy of the liquid drug with reduced consumption and cost, while minimizing pain and recovery time by directly activating skin tissues with high frequency waves.
Implementation Method 1
a first electrode inside the body, the first electrode commonly coupled to a portion of the plurality of the needles, and a second electrode inside the body, the second electrode commonly coupled to another portion of the plurality of the needles... A high frequency wave is applied between the first electrode and the second electrode

AI summary
Disclosed is an electrical signal applicable multi-needle syringe. The present invention comprises: a hollow cylinder; a needle hub closely coupled to the rear end of the cylinder; a plurality of needles placed at regular intervals inside the cylinder in such a way that the front ends are further protruded compared with the front end of the cylinder and the drug which is injected through the needle hub is sucked through the rear ends; a first electrode stored inside the cylinder, and commonly connected to a part of the plurality of needles; and a second electrode stored inside the cylinder, and commonly connected with the rest of the plurality of needles. Therefore, it is possible to inject a drug and to simultaneously apply a high frequency directly into the skin through a multi-needle injected into the skin by applying a high frequency between the first electrode and the second electrode, thereby promoting the activation of the injected drug.
