Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic applicators, such as thin disposable tape or paper, fail to provide a steady and conformable surface for applying cosmetics, leading to difficulties in achieving consistent application and can be irritating to the skin.
Innovation Solution
A flexible cosmetic applicator tool with a triangular shape and tacky coating, comprising rectilinear and curvilinear sides and vertices, which adheres to the skin and provides guided mechanisms for drawing various shapes and lines, allowing for precise and symmetrical cosmetic application without disrupting existing makeup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If thin disposable tape or paper is used as cosmetic applicator, then the device is simple and disposable, but it fails to provide a steady and conformable surface for applying cosmetics and can be irritating to the skin
Solution Approach 1:
The patent applies a flexible silicone gel material that conforms to the contours of facial features, providing a steady surface for cosmetic application while being gentle on the skin. The flexible nature allows the applicator to adapt to curved surfaces like eyebrows and eyelids without causing irritation, resolving the contradiction between operational ease and skin comfort.
Solution Approach 2:
The patent uses a composite structure combining a flexible silicone gel body with an adhesive layer. This composite material provides both the conformability needed for steady cosmetic application and the adhesion required to stay in place, while the silicone gel base prevents skin irritation compared to traditional disposable tape or paper materials.
2Reliability
If a flexible material with tacky coating is used, then the applicator adheres to skin and provides guidance, but the device complexity increases
Solution Approach 1:
The patent utilizes temperature-dependent adhesion parameters of the silicone gel material. The material becomes more adhesive when warmed by skin contact or body temperature, providing reliable adhesion without requiring complex mechanical attachment mechanisms. This parameter change approach maintains simplicity while achieving reliable skin adhesion.
Solution Approach 2:
The adhesive layer acts as an intermediary between the flexible silicone gel body and the skin surface. This intermediate layer provides the necessary bonding without requiring the main body of the applicator to be complex, allowing the silicone gel to maintain its simple flexible structure while achieving reliable adhesion through the intermediary adhesive layer.
3Ease of operation
If triangular shape with curvilinear sides is used, then guidance for drawing various shapes is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent incorporates curvilinear sides with varying curvature angles in the triangular applicator design. These curved edges provide natural guidance for drawing different shapes and lines on the face. The curvature variations are designed to match facial contours, improving ease of operation for applying cosmetics like eyebrow definition and eyeliner while the flexible material tolerates reasonable manufacturing variations.
Solution Approach 2:
Different regions of the triangular applicator have different curvature characteristics tailored to specific cosmetic application needs. The curvilinear sides feature varying curvature angles optimized for different facial areas, providing localized guidance quality that improves ease of operation. This local differentiation of geometric properties enhances functionality without requiring extreme manufacturing precision across the entire structure.
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
The tool enables efficient and precise application of cosmetics by providing a steady surface and adhering to the skin, allowing for various angles and shapes to be drawn, improving symmetry and ease of use while being gentle on the skin and reusable.
Implementation Method 1
the cosmetic applicator tool may comprise a tacky coating on the outer surface that provides an adhesive characteristic to adhere to a skin surface
Implementation Method 2
the cosmetic applicator tool may be further configured to: adhere to the skin based on the cosmetic applicator tool being comprised of the tacky coating on the outer surface and through the cosmetic applicator tool undergoing an increase in temperature, where the increase in temperature may be through exposure to warmth of the skin surface
