Adjustable Mascara Applicator with Deformable Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mascara applicators fail to adapt to individual eyelash or eyebrow characteristics, substance rheology, and desired makeup types, leading to inefficient application and frequent re-loading.
Innovation Solution
An adjustable applicator with a deformable portion and an adjuster element that allows the user to modify the distance between the applicator's ends, changing its shape and curvature to control the substance quantity and application style.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the applicator uses a fixed brush or comb structure, then the manufacturing is simple, but the applicator cannot adapt to different eyelash characteristics and substance rheologies
Solution Approach 1:
The patent implements a deformable portion in the applicator support that can change shape radially when the distance between its ends is varied. This dynamic structure allows the applicator to adapt its configuration to different eyelash characteristics, substance rheologies, and desired makeup types, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The patent employs an adjuster element that modifies the distance between the first and second ends of the deformable portion, thereby changing physical parameters such as the outside cross-section of the applicator member. This parameter adjustment enables the same applicator to serve multiple functions for different application needs without requiring multiple fixed-configuration applicators.
2Loss of time
If the applicator retains sufficient mascara quantity, then re-loading frequency decreases, but the user has difficulty controlling the quantity of substance loaded
Solution Approach 1:
The deformable portion allows dynamic adjustment of the applicator's outside cross-section, enabling the user to control the quantity of substance loaded onto the applicator member. By varying the radial deformation, the user can optimize both the retained substance quantity and the controllability, preventing both excessive re-loading and uncontrolled substance application.
3Object-generated harmful factors
If the applicator member prevents substance from reaching the deformable portion, then the deformable portion remains clean, but the applicator member requires special production measures
Solution Approach 1:
The patent applies substance barrier measures to the applicator member, effectively extracting or preventing the substance from reaching the deformable portion. This isolation protects the deformable portion from contamination while allowing the applicator member to be produced with standard methods, balancing cleanliness requirements with manufacturing simplicity.

AI summary
An applicator may include a support with a longitudinal axis. The support may include a stem, and a deformable portion including a first end and a second end, the deformable portion being arranged to deform elastically in a radial direction when a distance between the first and second ends is varied. The applicator may also include an applicator member fitted to the deformable portion between the first and second ends and extending continuously around the deformable portion. An adjuster element may be provided that is movable about at least the axis relative to the support and that is arranged to adjust the distance between the first and second ends of the deformable portion.
