Solution Overview

Problem

Existing methods for training mimetic muscles, such as those affected by aging, are inadequate in effectively correcting loose skin or flabbiness, as they lack the necessary mechanical stimulation and comfort for prolonged use.

Innovation Solution

A massage roller with a non-deformable roller base and elastic ridges is used to apply loads and shear stress to mimetic muscles, mimicking finger-pressure treatment by rotating and moving along the muscle's direction of contraction, while a coating layer prevents skin irritation and provides a soft touch.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a hard roller base is used to apply sufficient load to mimetic muscles, then muscle training effectiveness is improved, but skin damage risk increases

Engineering Contradiction:
Improvemuscle training effectivenessVSAvoidskin damage risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

Elastic ridges are introduced as an intermediary element between the hard roller base and the skin. These ridges deform elastically under pressure, distributing the load from the hard base across a larger skin contact area while maintaining sufficient training pressure on the mimetic muscles. This mediator structure prevents direct concentration of hard forces on the skin, thereby reducing damage risk while preserving training effectiveness.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The roller surface is designed with non-uniform local properties: hard roller base for structural integrity and load application, elastic ridges for localized pressure distribution and skin protection, and soft coating material for additional skin comfort. Each local region serves a specific function in the overall system of applying muscle training force while protecting the skin.

Inventive Principle:
Principle #3Local quality

2Object-affected harmful factors

If elastic ridges are added to the roller surface to protect skin, then skin safety is improved, but device complexity increases

Engineering Contradiction:
Improveskin safetyVSAvoidstructure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The elastic ridges are integrated directly into the roller base structure, forming a unified component rather than separate attachments. The coating layer is applied as a continuous surface that incorporates the ridge structures, combining multiple functions (protection, comfort, structural support) into a single integrated element, thereby minimizing the increase in device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The roller combines different material properties in a single structure: a hard roller base material for structural integrity and load bearing, and an elastic coating material forming the ridges for skin protection and comfort. This composite construction achieves multiple functions while maintaining a relatively simple overall device structure.

Inventive Principle:
Principle #40Composite materials

3Stability of the object's composition

If the roller base is made hard to maintain shape, then structural stability is improved, but comfort during use deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidcomfort during use
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The roller exhibits spatially varying mechanical properties: the roller base maintains hard structural stability for shape retention and load bearing, while the surface ridges and coating provide soft, compliant contact regions for skin comfort. Each local region is optimized for its specific function, resolving the contradiction between overall structural stability and local comfort.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The elastic ridges and soft coating material serve as intermediary layers between the hard roller base and the skin. These intermediaries absorb the discomfort that would result from direct hard surface contact, while the hard base beneath maintains structural stability and proper roller geometry.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

There is provided a method for training a mimetic muscle, comprising preparing a massage roller, the massage roller including a roller base made of a material free of elastic deformation, and a plurality of elastic ridges formed on a circumferential roller surface of the roller base so as to continuously extend in a direction along an axis of rotation of the roller base such that adjacent ridges in a rotational direction of the roller base are spaced; and creating a certain facial expression on a face so as to contract, in a contracting direction, a mimetic muscle to be trained; and reciprocating the massage roller along a continuously extending direction of the mimetic muscle with a location of a face skin corresponding to one end portion of the mimetic muscle being pressed so as to pull the mimetic muscles in a direction opposite to the contracting direction.
