Makeup Tool Retainer Using Transparent Hard Material
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional makeup tools with visible application parts made of soft materials lack sufficient rigidity, leading to unstable cosmetic application.
Innovation Solution
A makeup tool design featuring a barrel cylinder with a hard material retainer and an applying element, where the retainer is transparent for visibility and has a specific geometry to enhance cosmetic application stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the application part is formed of soft materials such as rubber or elastomer to provide visibility, then the visibility is improved, but the rigidity is insufficient leading to unstable cosmetic application
Solution Approach 1:
The retainer is constructed from a composite structure combining a transparent hard material (acrylic resin or polycarbonate) with an applying element (brush or sponge). This composite design allows the retainer to provide both visibility through transparency and rigidity through the hard material properties, while the applying element maintains its soft characteristics for cosmetic application.
Solution Approach 2:
The patent changes the material parameter from soft rubber/elastomer to hard transparent materials like acrylic resin or polycarbonate. This parameter change fundamentally alters both the optical properties (enhancing visibility) and mechanical properties (providing rigidity), resolving the contradiction between visibility and structural stability.
2Illumination intensity
If the retainer is made transparent to provide visibility of the target position, then the visibility is improved, but the structural stability may be compromised
Solution Approach 1:
The retainer combines transparent hard material with an applying element in a composite structure. The transparent acrylic resin or polycarbonate provides both visibility and structural stability, while the integrated brush or sponge maintains reliability for cosmetic application.
Solution Approach 2:
The application part is segmented into distinct functional zones: the transparent retainer portion for visibility and positioning, and the applying element (brush or sponge) for cosmetic application. This segmentation allows each part to optimize its specific function while working together as a unified structure.
3Illumination intensity
If the applying element is made visible through transparent materials, then the visibility is improved, but the rigidity and stability of cosmetic application deteriorates
Solution Approach 1:
The application part uses a composite structure where the transparent retainer (acrylic resin or polycarbonate) provides visibility and structural framework, while the integrated brush or sponge applying element delivers precise and stable cosmetic application. The composite design ensures both visibility and application precision are maintained.
Solution Approach 2:
Different parts of the application part have different material qualities optimized for their specific functions: the retainer is made of rigid transparent material for visibility and structural support, while the applying element uses softer materials (brush bristles or sponge) localized to the contact area for precise cosmetic application.

AI summary
To provide a makeup tool that is excellent in design and can perform stable application of a cosmetic, the makeup tool includes a barrel cylinder storing the cosmetic; and an application part attached to one end of the barrel cylinder, in which the application part includes an applying element capable of feeding the cosmetic from the barrel cylinder to apply the cosmetic, and a retainer that holds the applying element, and the retainer is formed of a hard material presenting visibility.
