Dual Applicator Device for Simultaneous Eyeliner Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyeliner applicators can only apply one line of product at a time, and attempting to apply multiple lines with different colors using separate applicators results in uneven spacing and lack of selective application or mixing of products.
Innovation Solution
A dual-applicator device with receptacles for holding two different products, where the applicators are in fluid communication and can dispense products simultaneously or independently, with adjustable barriers to prevent contamination and allow for mixing or uniform application, featuring applicator elements with varying shapes, materials, and flocking for better retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single applicator device is used to apply multiple lines of different colored products, then uniform spacing and selective application are improved, but device complexity increases
Solution Approach 1:
The applicator device is divided into multiple independent applicators (first applicator and second applicator), each capable of applying a different colored product. Each applicator has its own receptacle and applicator element, allowing independent operation while maintaining uniform spacing through the shared structural framework.
Solution Approach 2:
The single applicator device performs multiple functions by incorporating multiple applicators that can apply different colored products simultaneously or independently. The device provides both selective application (using one applicator at a time) and simultaneous application (using both applicators), eliminating the need for multiple separate eyeliners.
2Adaptability or versatility
If multiple separate eyeliners are used to apply multiple lines of different colors, then product variety is improved, but hand control and uniform spacing deteriorate
Solution Approach 1:
Multiple separate eyeliner applicators are merged into a single integrated device with a shared gripping member and structural framework. This allows the user to hold and control one device while applying multiple colored lines simultaneously or sequentially, improving hand control and uniform spacing while maintaining product variety through multiple receptacles and applicator elements.
3Device complexity
If a single receptacle is used to hold one product, then device simplicity is maintained, but the ability to apply multiple colors simultaneously is lost
Solution Approach 1:
The single receptacle is segmented into multiple receptacles (first receptacle and second receptacle), each holding a different colored product. Each receptacle connects to its own applicator element, enabling simultaneous application of multiple colors while maintaining a relatively simple overall device structure that can be manufactured efficiently.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the simultaneous or independent application of two or more lines of different products with uniform spacing, allowing for desired blending effects and improved product retention, while preventing contamination between applicators.
Implementation Method 1
The applicator element may include fibers configured to retain the product and apply at least one line of product to the skin of the user upon application
Implementation Method 2
The product flow to the applicators is either gravity assisted or is through the deformable receptacles
