Cosmetic Applicator Variable Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combined cosmetic applicator brushes with built-in powder storage lack control over powder flow rates and do not allow for easy replacement or switching of cosmetic powders, leading to inconsistent application and the need for separate containers or new devices when the powder is depleted or changed.
Innovation Solution
A combined applicator brush device with a variable flow mechanism and replaceable cartridges that enable adjustable powder flow rates and easy switching between different cosmetic powders, allowing users to control the amount of powder applied and change powder types without needing separate containers or new devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a combined applicator brush and cosmetic powder storage device is used, then ease of operation is improved by manipulating a single device, but control over powder flow rate deteriorates resulting in too little or too much cosmetic powder applied
Solution Approach 1:
The patent implements a variable flow mechanism that allows the user to dynamically adjust the powder flow rate during application. This is achieved through a flow control component that can be positioned at different locations along the powder delivery path, enabling real-time modification of the powder flow characteristics to match user preferences and application requirements.
2Device complexity
If a combined applicator brush and cosmetic powder storage device is used, then device integration is improved, but adaptability deteriorates when cosmetic powder is exhausted or changed
Solution Approach 1:
The patent divides the combined device into separable components: a reusable applicator brush assembly and replaceable cosmetic powder cartridges. This segmentation allows the powder cartridge to be easily removed and replaced when exhausted or when a different cosmetic formulation is desired, while the applicator brush mechanism remains intact and reusable.
Solution Approach 2:
The applicator brush assembly is designed as a universal platform that can accommodate different types of cosmetic powder cartridges. The standardized interface and flow control mechanism enable the same applicator to work with various cosmetic formulations, enhancing versatility without requiring multiple specialized devices.
3Ease of operation
If existing combined cosmetic application devices are used, then ease of operation is improved, but loss of time increases due to needing separate containers or new devices when powder is depleted
Solution Approach 1:
The patent prepares multiple cosmetic powder cartridges in advance, allowing users to pre-select and stage different cosmetic formulations. When one cartridge is exhausted, a replacement is already available, eliminating the time required to clean, refill, or switch between separate containers during the cosmetic application routine.
