Personal Cleaning Article With Multi-Roughness Exfoliating Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable personal care cleaning articles fail to provide a wide range of scrubbing actions and varying levels of mechanical cleaning, often causing irritation and inadequately removing residue, with users needing different levels of roughness for different body areas and situations.
Innovation Solution
A personal care cleaning article with distinct regions of varying roughness, featuring interposed smooth and rough portions, apertures, and layers with different textures, allowing for customizable cleaning and exfoliation, and including a porous core member for enhanced handleability and cleaning composition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If highly abrasive materials such as loofa or pumice are used for exfoliation, then dead skin cells are effectively removed, but user irritation and discomfort increase
Solution Approach 1:
The cleaning article incorporates multiple regions with different roughness levels (first region with higher roughness for effective exfoliation, second region with lower roughness for gentler cleaning). This allows different areas of the article to provide different levels of mechanical action, enabling effective dead skin cell removal in some areas while minimizing irritation in others.
2Ease of manufacture
If uniform roughness is provided across the entire cleaning article, then manufacturing is simplified, but user needs for different body areas and situations cannot be met
Solution Approach 1:
The cleaning article is divided into distinct regions (first region and second region) with different roughness characteristics. Each region can be optimized for specific cleaning needs, allowing users to select appropriate areas for different body parts or skin conditions, thereby providing versatility without overly complicating the manufacturing process.
3Device complexity
If traditional single-roughness pads are used, then device complexity is reduced, but the ability to provide varying scrubbing actions for different users and situations is limited
Solution Approach 1:
The article incorporates multiple regions with different roughness levels (first region with higher roughness for effective exfoliation, second region with lower roughness for gentler cleaning). This allows different areas of the article to provide different levels of mechanical action, enabling effective dead skin cell removal in some areas while minimizing irritation in others.
4Productivity
If conventional cleaning articles are used, then basic cleaning is achieved, but residue removal from skin is inadequate
Solution Approach 1:
The cleaning article incorporates a porous core member that provides enhanced handleability and can hold cleaning compositions. The porous structure allows the material to absorb and retain cleaning agents, which are then released during use to improve residue removal effectiveness from the skin.
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 article provides a customizable cleaning experience, effectively removing dirt and dead skin cells with varying degrees of scrubbing action, reducing irritation, and improving handleability, thus meeting the diverse needs of users.
Implementation Method 1
The rough portions comprise between about 5-65% of the total surface area of the first side of the article... effectively dislodges foreign or unwanted matter
Implementation Method 2
a porous core member for enhanced handleability and cleaning composition

AI summary
The present invention provides personal cleaning articles useful for cleaning and/or exfoliating the skin. These articles provide multiple distinct patterns of relatively smooth and coarse elements to provide a user the ability to readily achieve the desired degree of cleansing and/or exfoliation. Further, the article provides a relatively smooth apertured outer layer and a relatively coarse underlying layer whereby a user can, with the application of varied amounts of pressure, more readily achieve and control a wider range of mechanical cleaning and/or exfoliating action against the skin. In certain aspects, the article may also be impregnated with one or more topical skin cleaning and/or exfoliating compounds.
