Cosmetics Applicator with Vibrating Brush and Cartridge Probe
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic applicators often become coated or lost when carried with cosmetics, and existing devices lack enhanced application capabilities for rotational and oscillating motions necessary for effective product application.
Innovation Solution
A cosmetics applicator with a brush head connected to a motion actuator for oscillatory, rotational, or combined motions, featuring a cartridge with a dispensing actuator and a one-way valve applicator probe, allowing coordinated dispensing and motion for enhanced application, including a planetary gear system for single-motor operation and customizable bristle patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional applicator is carried with cosmetics in a compact, then the applicator can be stored with the cosmetic, but the applicator becomes coated or lost
Solution Approach 1:
The applicator is divided into separate functional modules: a reusable handle with motion actuator and a disposable cartridge containing the cosmetic and applicator probe. This segmentation prevents the applicator from becoming coated while allowing the cartridge to be easily replaced, solving both retention and contamination issues.
Solution Approach 2:
The applicator probe is integrated into a disposable cartridge that is discarded after use. This eliminates the problem of cosmetic coating on reusable applicators, as the probe is replaced rather than cleaned and reused.
2Adaptability or versatility
If a motion actuator is added to provide oscillatory and rotational motions, then the application capability is enhanced, but the device complexity increases
Solution Approach 1:
A single motion actuator is designed to perform multiple functions by varying its operational parameters. The actuator can produce oscillatory motion, rotational motion, or combined motions, providing versatile application capabilities for different cosmetic types and application requirements without requiring multiple separate actuators.
Solution Approach 2:
The motion actuator employs variable speed and variable frequency mechanisms that allow dynamic adjustment of motion characteristics. This enables the same actuator to adapt to different application needs by changing operational parameters rather than requiring structural reconfiguration.
3Ease of operation
If a dispensing actuator is integrated into the cartridge, then the cosmetic dispensing is controlled, but the manufacturing complexity increases
Solution Approach 1:
The dispensing actuator is integrated directly into the cartridge assembly, combining the cosmetic storage and dispensing functions in a single unit. This merging simplifies the overall device architecture by eliminating separate dispensing mechanisms and allows for pre-assembly of the cartridge, reducing manufacturing complexity.

Function Achieved in This Case
The solution provides a convenient, efficient, and versatile applicator that prevents leakage and enhances application of various cosmetic forms, ensuring effective and controlled distribution of cosmetics with reduced risk of loss or coating issues.
Implementation Method 1
a motion actuator operative to move the brush head in a vibrational motion, a rotational motion or a combination thereof
Implementation Method 2
The distal tip serves as a one-way valve, which opens by internal pressure to allow application of the cosmetic but when closed seals the probe so that no material leaks out

AI summary
A cosmetics applicator includes a housing including a movable brush head, and a motion actuator operative to move the brush head in a vibrational motion, a rotational motion or a combination thereof. A cartridge contains a cosmetic to be dispensed. A dispensing actuator is operative to dispense the cosmetic out of the cartridge. The cartridge includes an applicator probe that extends forward to a center of the brush head and the cosmetic is dispensed out of a distal tip of the probe.
