Interlinked Cosmetic Applicator for Even Mascara Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mascara applicators fail to provide even application and separation of lashes without clumping, as they require users to twist and turn their wrists, which not all users can do effectively, and often necessitate using separate applicators for different functions.
Innovation Solution
A cosmetic applicator with interlinked parts forming a non-zero angle at their interface, comprising a hard comb part and a soft bristle part, mimicking the twirl of the wrist for effortless and even application, allowing the two parts to blend application in a single stroke.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single mascara brush is used, then the device complexity is reduced, but the application quality deteriorates due to inability to provide both application and separation functions
Solution Approach 1:
The patent combines multiple applicator parts (application brush, comb, and separation elements) into a single integrated mascara applicator. The first applicator part includes an application brush with bristles for applying mascara, while the second applicator part includes a comb with teeth for separating and arranging lashes. This merging allows the user to achieve both application and separation functions with one device, eliminating the need to switch between multiple applicators and thereby improving application quality without significantly increasing device complexity.
Solution Approach 2:
The mascara applicator is designed with multi-functionality by incorporating different functional elements in its two parts. The first part performs the primary function of applying mascara to lashes, while the second part performs the secondary function of combing and separating lashes. This universal design enables a single applicator to fulfill multiple cosmetic functions that were previously required separate tools, thus resolving the contradiction between device simplicity and application quality.
2Ease of operation
If conventional mascara brushes are used, then ease of operation is reduced due to requirement of wrist twisting, but the application evenness could be improved with proper technique
Solution Approach 1:
The patent introduces dynamic functionality by making the second applicator part (comb) rotatable relative to the first applicator part (application brush). The comb can rotate about the longitudinal axis of the applicator, allowing it to automatically align with the direction of application strokes. This dynamic adjustment eliminates the need for users to manually twist their wrists to achieve proper comb orientation, thereby improving ease of operation while maintaining application evenness through automatic alignment.
Solution Approach 2:
The rotatable comb design enables self-service functionality where the comb automatically orients itself in the correct position during application. As the user moves the applicator along the lashes, the comb naturally aligns with the stroke direction without requiring active user manipulation or wrist twisting. This self-aligning mechanism resolves the contradiction by making the applicator easier to operate while maintaining precise, even application results.
3Manufacturing precision
If separate applicators are used for application and combing, then application quality is improved, but device complexity and number of parts increases
Solution Approach 1:
The patent merges separate application and combing applicators into a single integrated unit. The first applicator part contains the application brush for depositing mascara, while the second applicator part contains the comb for separating and arranging lashes. Both functional parts are connected to a common handle, creating one unified device that performs multiple functions. This merging reduces the total number of separate parts and tools needed while maintaining the application quality benefits of having specialized application and combing elements.
Solution Approach 2:
The integrated applicator achieves universality by incorporating multiple cosmetic functions within a single device. Users can perform both mascara application and lash combing/separation with one tool, eliminating the need to switch between separate applicators. This multi-functional design maintains high application quality by preserving the specialized features of each function (brush bristles for application, comb teeth for separation) while reducing device complexity and the number of individual parts required.
