Adjustable Cosmetic Applicator with Rotating Brush
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mascara applicators have a straight handle and brush arrangement, leading to unstable makeup application postures and discomfort for users due to the need to raise their arms to apply mascara liquid evenly.
Innovation Solution
An adjustable cosmetic applicator with a handle unit, rod unit, and applying unit, where the applying unit features a brush rod with a pinion driving part and an elastic member, allowing the angle of the brush to be adjusted through user manipulation via a linear motion of the rod unit, converting into rotary motion to change the brush's angle between 0° and 90°.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handle and brush are arranged in a straight line, then the structure is simple, but the user must raise their arm to shoulder height causing unstable posture and poor makeup application
Solution Approach 1:
The brush assembly is made rotatable relative to the handle through a pivot mechanism, allowing the brush angle to be dynamically adjusted during use. This enables the user to change the brush orientation to achieve a comfortable application posture without raising the arm to shoulder height, while the handle-rod-brush straight-line configuration is maintained when not in use.
2Adaptability or versatility
If the brush angle is fixed, then the structure is simple, but it cannot accommodate different user preferences and applying habits
Solution Approach 1:
The brush assembly incorporates a pivot mechanism with a rotation manipulation unit that enables dynamic angle adjustment. The brush can be rotated to different angles and locked in position, accommodating various user preferences and applying habits while maintaining structural simplicity through the use of a compact mechanical adjustment mechanism.
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 more natural and comfortable application of cosmetic liquid, accommodating user preferences and habits by allowing adjustable angles, thus improving the stability and ease of makeup application.
Implementation Method 1
an elastic member (147) adapted to provide an elastic restoring force thereto, the elastic member (147) being supported against the rod unit (130) at one end thereof and against the applying unit (140) at the other end thereof
Implementation Method 2
a pinion driving part (143) disposed at the other end thereof in such a manner as to be rotated around a rotary shaft (145) through the reception of the linear motion of the rod unit (130)

AI summary
The present invention relates to an adjustable cosmetic applicator including: a handle unit adapted to be used as a cap coupled to a cosmetic container body; a rod unit adapted to be manipulated by means of the handle unit; and an applying unit adapted to be operated cooperatively with the rod unit in such a manner as to be adjusted in angle. The adjustable cosmetic applicator according to the present invention allows the angle of the applying unit to be adjusted arbitrarily by means of the user, thereby permitting the cosmetic liquid to be applied in more natural and comfortable manners and further achieving the make-up according to the user's applying habit or preference.
