Mascara Applicator Open-Loop Chain Structure for Flexible Combing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mascara applicators lack flexibility and adaptability, leading to imperfect application, clumping, and rapid clogging, and fail to replicate the professional makeup artist's combing effect.
Innovation Solution
An applicator with a movable part comprising chains of open loops, connected to a fixed part, allowing for relative movement, enhances flexibility and adaptability, enabling gentle penetration and combing of eyelashes with transverse movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an applicator with movable parts is used to improve flexibility and adaptability, then the application quality and comfort are improved, but the device complexity increases
Solution Approach 1:
The applicator incorporates movable parts that can move relative to a fixed part, allowing the bristles to adapt dynamically to the shape and position of eyelashes during application. This dynamic structure enables the applicator to adjust its configuration automatically based on the contours it encounters, improving flexibility without requiring complex control mechanisms.
Solution Approach 2:
The applicator is divided into a fixed part and multiple movable parts, each capable of independent movement. This segmentation allows different sections of the applicator to respond independently to the geometry of the eyelashes, providing localized adaptation while maintaining overall structural simplicity.
2Ease of manufacture
If traditional rigid applicators are used to simplify manufacturing, then the ease of manufacture is improved, but the application result and comfort of use deteriorate
Solution Approach 1:
The movable parts are designed with simple connection mechanisms that allow relative movement while maintaining ease of manufacturing. The movable parts can be attached using straightforward methods such as injection molding or simple fastening mechanisms, avoiding complex assembly processes while still achieving the desired flexibility and comfort during use.
3Manufacturing precision
If movable parts are added to improve application quality, then the adaptability is improved, but the manufacturing complexity increases
Solution Approach 1:
The movable parts are designed with simple connection mechanisms that allow relative movement while maintaining ease of manufacturing. The movable parts can be attached using straightforward methods such as injection molding or simple fastening mechanisms, avoiding complex assembly processes while still achieving the desired flexibility and comfort during use.

AI summary
Applicator for cosmetic product having an elongate general shape in a longitudinal direction, including a fixed part and a part movable in relation thereto. The movable part includes protrusions, at least one chain having a strand forming a succession of open loops, the chain extending substantially parallel to the longitudinal axis of the applicator. The fixed part includes at least two links, at least two of the open loops on each chain being passed through by a link of the fixed part. Thus, each chain of the movable part is fastened with at least one degree of freedom to the fixed part, enabling relative movement of the chain in relation to the fixed part longitudinally. This improves quality of the application of the product and gives the applicator a sensation of flexibility, even if the applicator is constituted by a rigid material. The applicator can be made by additive manufacturing.
