Solution Overview

Problem

Existing cosmetic masks lack ease of wear and removal, and their electrodes often provide inappropriate stimulation due to inadequate sizing and elasticity, resulting in suboptimal cosmetic effects.

Innovation Solution

A cosmetic mask designed as an elastic band that wraps around the occiput from the chin tip, with a detachable and attachable wrap-around section using a hook-and-loop fastener, and electrodes specifically sized and positioned to target individual facial muscles effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the mask body is made of elastic material to improve wearability, then the ease of operation is improved, but the manufacturing precision deteriorates due to deformation during wear

Engineering Contradiction:
Improveease of wearVSAvoidpositioning accuracy
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent applies preliminary action by pre-forming the mask body with built-in elastic deformation that automatically activates upon wearing. The mask is designed with predetermined elastic regions that deform in specific directions when stretched during application, ensuring accurate positioning of electrode sections on target muscle areas without requiring manual adjustment during wear.

Inventive Principle:
Principle #10Preliminary action

2Area of stationary object

If the electrode sections are made large to improve stimulation coverage, then the area of stimulation is improved, but the stimulation appropriateness deteriorates due to inability to target specific muscles

Engineering Contradiction:
Improvestimulation coverageVSAvoidstimulation appropriateness
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The patent applies segmentation by dividing the electrode system into multiple independent electrode sections, each corresponding to specific facial muscle groups. The mask body includes first electrode sections for zygomatic muscles, second electrode sections for masseter muscles, and third electrode sections for cervical muscles. This segmentation allows targeted stimulation of individual muscle groups while maintaining appropriate stimulation parameters for each specific muscle type.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If the mask design is simplified to improve ease of wear, then the device complexity is reduced, but the cosmetic effect deteriorates due to inadequate muscle targeting

Engineering Contradiction:
Improvemask structureVSAvoidcosmetic effect
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent applies universality by designing a single integrated mask body that simultaneously performs multiple functions: positioning electrode sections on different facial muscle groups, providing elastic deformation for accurate fitting, and enabling comprehensive facial contouring. The mask body integrates first, second, and third electrode sections along with elastic deformation regions into one universal device that addresses multiple cosmetic concerns (cheek lifting, jawline definition, neck contouring) in a single application.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The present invention provides a cosmetic mask that can be easily attached and detached and has an enhanced cosmetic effect, and an electric stimulator applicable to the cosmetic mask. A cosmetic mask worn on the face of a user, made of flexible elastic material, and formed in a substantial band shape to be wrapped around the occiput from a chin tip through right and left cheeks includes a mouth periphery that covers at least a location corresponding to the mouth with an opening, a mandible section that covers the chin tip and at least a part of the lower surface of the mandible, a cheek section that covers a part of the cheek, and a wrap-around section that is wrapped around the lateral sides and the occiput. Further, the cosmetic mask includes a pair of stimulators that provides electric or ultrasonic stimulation to location corresponding to at least one of the zygomatic muscles and the masseter muscle of a user, and a stimulator fitting section to fit in each of the stimulators in the cheek section.
