Solution Overview

Problem

Current facial brushes, whether rotating or sonic, often fail to provide an even distribution of cleansing agents across the face, leading to incomplete cleaning and uneven application of moisturizers.

Innovation Solution

A brush head design featuring radially symmetric silicone ribbons with varying heights, forming waves and channels, optimized for use with dual motor brushes that combine rotation and sonic vibration, ensuring even distribution of soap and lotions across the face.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If conventional brush head configurations are used, then the brush structure is simple, but the distribution of cleansing agents is uneven

Engineering Contradiction:

Improvedistribution of cleansing agentsVSAvoidbrush head structure

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The brush head is divided into multiple discrete ribbons arranged in a radial pattern, each ribbon acting as an independent element for distributing cleansing agents. This segmentation allows for more uniform coverage across the brush surface compared to conventional solid brush heads.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The ribbons are positioned at specific radial intervals and have varying heights, creating localized variations in the brush head structure. This local quality variation ensures that cleansing agents are distributed evenly across different areas of the face, with each ribbon contributing to specific zones.

Inventive Principle:

Principle #3Local quality

2Reliability

If dual motor brushes combining rotation and sonic vibration are used, then the cleansing effectiveness is improved, but the device complexity increases

Engineering Contradiction:

Improvecleansing effectivenessVSAvoidmotor system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The brush head design integrates seamlessly with the dual motor system, combining the rotational and sonic vibration functions into a unified cleansing mechanism. The radial ribbon structure responds to both rotational motion and sonic vibrations, merging the effects of both motors for enhanced cleansing effectiveness.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The brush head structure is designed to be dynamic, adapting its behavior based on the combined input from both motors. The ribbons flex and move in response to sonic vibrations while maintaining their radial arrangement during rotation, allowing the system to leverage both motor functions effectively.

Inventive Principle:

Principle #15Dynamics
