Integrated Cleanser Brush Head for Continuous Skin Cleansing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cleansing routines require a three-step process involving applying cleanser, using a cleansing device, and rinsing, which can be inefficient if an inadequate amount of cleanser is initially applied, necessitating interruption and reapplication.
Innovation Solution
Integration of a cleanser or cleanser dispenser with a cleansing device, such as a brush, allowing for continuous cleanser application during use, reducing steps and time through a combination of bristles and dispensing mechanisms like tufts or sponges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a three-step cleansing process (apply cleanser, use cleansing device, rinse) is used, then the cleansing can be effective, but the time and number of steps increase when additional cleanser needs to be applied
Solution Approach 1:
The patent combines the cleanser application function and the mechanical cleansing device into a single integrated unit. The cleanser is stored in a reservoir on the cleansing device head and dispensed through applicators during device operation, eliminating the need for separate cleanser application steps and reducing overall cleansing time while maintaining effectiveness
Solution Approach 2:
The cleanser is pre-loaded into the device reservoir before use, allowing the cleanser to be automatically dispensed at the appropriate moment during the cleansing process without requiring the user to separately apply it, thus reducing time loss while ensuring proper application
2Reliability
If a three-step cleansing process is used, then thorough cleansing is achieved, but the number of steps and complexity increase
Solution Approach 1:
The patent merges multiple cleansing functions (cleanser storage, dispensing, and mechanical cleansing) into a single device, reducing the number of separate steps from three to essentially one continuous action, thereby improving ease of operation while maintaining thoroughness through the integrated design
Solution Approach 2:
The device automatically dispenses cleanser during operation without requiring the user to manually apply it, making the process simpler and more self-service oriented while ensuring consistent cleanser application for thorough cleansing
3Ease of operation
If manual cleanser application is used, then the user has control over application amount, but consistent application rate cannot be maintained
Solution Approach 1:
The device incorporates a pump system that automatically dispenses cleanser at a controlled rate during device operation, providing consistent application without requiring manual measurement or estimation, thus achieving precision in application rate while maintaining ease of use through automated control

AI summary
A cleansing workpiece suitable for use with a personal care appliance. The cleansing workpiece includes a cleanser and a cleansing component, such as a number of tufts each having a plurality of bristles. In use, the cleansing workpiece can be rotated, reciprocated, oscillated, etc., over a subject's skin in order for the cleansing workpiece to dispense or apply a quantity of the cleanser onto the subject's skin and/or for the cleansing component to clean, massage, and/or exfoliate a subject's skin with the aid of dispensed cleanser. The cleanser may be continuously applied to the subject's skin as the cleansing component.
