Massage Roller With Elastic Ridges For Mimetic Muscle Training
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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.
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
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.
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.

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.
