Integrated Skin Care Device Combining Ultrasound and Drug Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skin care devices are unable to simultaneously deliver ultrasound and apply drugs to the skin, limiting their effectiveness in treating wrinkles, skin elasticity, and pain relief.
Innovation Solution
A skin care device with a cartridge that includes a head part for skin contact, a drug discharge portion, an output unit for delivering electrical energy such as ultrasound, laser, or microwave, and a container loading unit with a needle part to apply a drug solution, allowing simultaneous ultrasound delivery and drug application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a skin care device is designed to deliver ultrasound or other electrical energy to the skin, then treatment effects such as wrinkle removal and skin elasticity improvement are achieved, but the device cannot simultaneously apply drug solutions to the skin
Solution Approach 1:
The patent combines the ultrasound output unit and drug discharge portion into a single integrated head part. The cartridge structure merges the container loading unit with the output unit, allowing both ultrasound delivery and drug application functions to be performed simultaneously through one unified device rather than requiring separate devices.
Solution Approach 2:
The head part is designed with dual functionality: it contains both the output unit for delivering electrical energy (ultrasound, laser, light, microwave) and the drug discharge portion for applying drug solutions. This multi-functional design allows a single device to perform multiple skin treatment functions that previously required separate devices.
2Productivity
If separate devices are used for ultrasound delivery and drug application, then each function can be optimized independently, but treatment time is extended and operational convenience is reduced
Solution Approach 1:
By merging the ultrasound delivery system and drug application system into a single integrated device, the patent enables both treatments to be performed simultaneously in one procedure, eliminating the need for separate treatment sessions and reducing total treatment time.
Solution Approach 2:
The integrated design allows continuous simultaneous delivery of ultrasound energy and drug application throughout the treatment process, maximizing treatment efficiency by performing both functions concurrently rather than sequentially.
3Ease of operation
If a single device integrates both ultrasound delivery and drug application functions, then treatment efficiency is improved, but the device structure becomes more complex
Solution Approach 1:
The device is segmented into modular components: a replaceable cartridge containing the head part with integrated functions, and a handpiece. This segmentation allows the complex integrated head part to be easily replaced as a unit, simplifying operation and maintenance despite the internal complexity.
Solution Approach 2:
The container loading unit is nested within the cartridge structure, which itself is attached to the handpiece. The needle part is nested within the container loading unit, and the drug discharge portion is integrated within the head part. This nested arrangement consolidates multiple functions into a compact integrated structure that is easy to operate.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the simultaneous delivery of electrical energy and drug application to the skin, enhancing treatment efficacy for skin rejuvenation and pain relief.
Implementation Method 1
an output unit that is provided in the head part and outputs electrical energy including at least one of ultrasound, laser, light, a low-frequency microwave, a mid-frequency microwave, and a high-frequency microwave toward the target part
Implementation Method 2
a needle part that is provided in the container loading unit to communicate with the container loading unit and the drug discharge portion and breaks a stopper of the drug solution container loaded on the container loading unit to apply the drug solution stored in the drug solution container to the target part
Implementation Method 3
a plunger that pushes the container packing in a direction approaching the needle part to discharge the drug solution stored in the drug solution container to the drug discharge portion

AI summary
The present invention relates to a skin care device for use in both ultrasound delivery and drug application. The skin care device including at least: a cartridge that includes a head part contacting a target portion of the skin and a drug discharge part formed in the head part; an output unit that outputs, toward the target portion, electrical energy including ultrasound, laser, light, low-frequency microwave, medium-frequency microwave, or high-frequency microwave; a container loading unit that is detachably coupled to the head part; a drug solution container that stores a drug solution; and a needle unit that is provided in the container loading unit to allow the container loading unit to communicate with the drug discharging part, and breaks the lid of the drug solution container so that the drug solution stored in the drug solution container is applied to the target portion.
