Oscillating Elastomeric Cleansing Head for Deep Skin Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handheld skin cleansing devices fail to effectively clean the interstitial spaces between skin cells and often cause skin roughening due to the buildup of cleansers, dirt, and dead cells at the bristle base, as they primarily focus on the surface layer and lack deep cleaning capabilities.
Innovation Solution
A cleansing device with an oscillating head featuring elastomeric cleansing features that provide a total displacement of 0.5 mm to 12 mm, allowing for deeper penetration and effective cleaning of interstitial spaces, combined with a skin-stretching mechanism that utilizes a stick-slip action to remove dead cells and dirt without causing discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional bristle brushes are used for skin cleansing, then the device structure is simple and easy to manufacture, but the cleaning effectiveness is limited to surface layer only and cannot reach interstitial spaces between skin cells
Solution Approach 1:
The patent employs an oscillating mechanism that moves the cleansing head in a dynamic pattern, enabling the bristles to reach into interstitial spaces between skin cells. The oscillation frequency and amplitude are controlled to provide effective deep cleaning while maintaining ease of manufacture through a relatively simple mechanical oscillation system.
2Productivity
If bristle brushes are used for mechanical action against skin, then the device can provide cleaning action, but the brushes tend to build up cleansers, dirt, and dead skin cells at the base of bristles that is difficult or impossible to clean off
Solution Approach 1:
The oscillating mechanism provides periodic action that prevents the buildup of contaminants at the base of bristles. The continuous oscillation disrupts the accumulation of cleansers, dirt, and dead skin cells, keeping the bristle base relatively clean and maintaining cleaning effectiveness throughout use.
3Device complexity
If conventional brushes lift facial skin cells but do not remove them, then the device structure is simple, but the effect is skin roughening rather than smoothing
Solution Approach 1:
The oscillating mechanism transforms the static lifting action of conventional brushes into a dynamic motion that effectively removes lifted skin cells. The oscillation provides a combination of lifting and sweeping actions that smooth the skin surface rather than roughening it, while maintaining relatively simple device structure.

AI summary
A cleansing device for mammalian skin includes a cleansing head having a plurality of elastomeric cleansing features extending away from the first surface and having an aspect ratio of about 1:5 to 10:1. The cleansing head is attached to a handle adapted to apply oscillating movement to one or more cleansing head sections to provide a total displacement per oscillation of about 2 mm to 8 mm at a frequency of about 5 Hz to 30 Hz.
