Mascara Applicator with Segmented Brush Sections
Solution Overview
Problem
Conventional mascara applicators fail to effectively lift eyelashes from their bases, provide uniform voluminousness, and adequately apply mascara to detailed areas like the inner corner and lower eyelashes, resulting in a monotone application and inability to achieve omni-directional expansion.
Innovation Solution
A mascara applicator with a core member curved into an upward arch, featuring upper and lower application parts with radially held brush fibers, where the upper part is configured as a fan with a central angle of 45° to 120° and the lower part as a wide fan with 240° to 315°, forming combs with triangular and wave-shaped fins to ensure even mascara distribution and separation of eyelashes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the bundle of brush fibers is formed with a fan-shaped horizontal section, then the mascara can be applied to a wide region of the eyelashes, but the applicator cannot be fitted to the curved bases of the eyelashes to lift them up
Solution Approach 1:
The applicator is divided into multiple application sections along the longitudinal direction, each with different horizontal sectional shapes (circular, decentering circle, fan-shaped). This segmentation allows different sections to perform different functions: some sections provide wide coverage while others are designed to fit curved eyelash bases for lifting.
Solution Approach 2:
Different sections of the applicator are given different local characteristics through varying horizontal sectional shapes. The circular sections provide broad coverage for general application, while the decentering circle and fan-shaped sections are optimized for fitting curved surfaces and lifting eyelashes at specific locations.
2Adaptability or versatility
If the applicator provides wide coverage for omni-directional expansion, then the eyelashes can expand in all directions, but the mascara cannot be effectively adhered to the bases of the eyelashes to provide voluminousness
Solution Approach 1:
The applicator is segmented into multiple sections with different horizontal sectional shapes arranged along the longitudinal direction. This allows specific sections (circular and decentering circle shapes) to be positioned for precise mascara application at the eyelash bases, while other sections (fan-shaped) provide wide coverage for omni-directional expansion.
Solution Approach 2:
The invention adds the longitudinal dimension to the horizontal sectional shape variations. By arranging different horizontal sectional shapes (circle, decentering circle, fan) at different longitudinal positions, the applicator achieves both precise base application and wide coverage expansion in three-dimensional space.
3Device complexity
If the bundle of brush fibers is formed into a simple fan shape, then the structure is simple, but the application result is monotone and cannot achieve different applications based on application sections
Solution Approach 1:
The applicator is divided into multiple application sections along the longitudinal direction, each with distinct horizontal sectional shapes (circular, decentering circle, fan-shaped). This segmentation enables different sections to provide different application effects, achieving versatile multi-purpose application while maintaining a relatively simple overall brush fiber bundle structure.

AI summary
An object of the present invention is to provide a mascara applicator capable of being fitted to the curved bases of eyelashes to lift up eyelashes, providing voluminousness to the eyelashes by adhering a mascara to the bases of the eyelashes, widely applying the mascara so that the eyelashes expand in the form of a fan, properly and widely applying the mascara to detailed parts such as the tail and inner corner of the eye, as well as lower eyelashes, and also obtaining an all direction expansion mascara application result. A mascara applicator (1), which has a long core member (2), and an application part configured by an upper application part (5) and a lower application part (6) that are supported by the core member (2), extend from the core member to the outside in a horizontal sectional direction, carry a mascara thereon, and apply the mascara to eyelashes, the lower application part being set to be shorter than the upper application part in the horizontal section, wherein a cross section of the upper application part along a longitudinal direction of an axis of the core member is shaped into a series of crests with one and half crests along the longitudinal direction between a base end part and tip part of the core member.
