Cosmetic Applicator Head With Roller Ball for Continuous Fluid Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic applicators require frequent dipping into the product reservoir, leading to inefficiency in applying a sufficient amount of cosmetic or care products, and lack a built-in massaging and cooling function.
Innovation Solution
A cosmetic applicator head with a spherical ball mounted in a ball socket at its distal end, allowing for efficient product delivery through rotation and providing massaging and cooling effects, is integrated into a package with a receptacle and stem, enabling continuous application without frequent re-dipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional dip applicator is used, then the applicator can be simple in structure, but it requires frequent dipping into the cosmetic bulk to complete the application process
Solution Approach 1:
The applicator is divided into a reservoir portion containing cosmetic bulk and a separate application portion with a roller ball. This segmentation allows the reservoir to store a larger amount of cosmetic while the application portion can be repeatedly dipped into the reservoir without requiring the entire applicator to be large and complex.
Solution Approach 2:
The applicator transitions from a simple linear dip-wand structure to a three-dimensional configuration with a reservoir portion that can expand in multiple directions. The reservoir portion includes a body with width, depth, and height dimensions, allowing it to hold more cosmetic product while maintaining a manageable overall size.
2Ease of manufacture
If a conventional dip applicator is used, then the applicator can be easy to manufacture, but it requires considerable amount of cosmetic liquid capacity to avoid frequent dipping
Solution Approach 1:
By separating the applicator into a reservoir portion and an application portion, the design allows the reservoir to be optimized for capacity while the application portion remains simple. The reservoir portion can be molded as a single piece with integrated dispensing features, maintaining manufacturing simplicity while achieving the desired cosmetic liquid capacity.
Solution Approach 2:
The application portion with the roller ball is effectively nested within or alongside the reservoir portion structure. The reservoir body contains cosmetic bulk that the application portion can access through controlled dispensing, allowing the system to hold considerable cosmetic liquid while keeping the application mechanism simple and easy to manufacture.
3Device complexity
If a conventional applicator is used, then the applicator can be simple in design, but it lacks massaging and cooling functions
Solution Approach 1:
The applicator is designed to perform multiple functions: it applies cosmetic products through the roller ball mechanism and simultaneously provides massaging and cooling functions. The reservoir portion structure with its contours and the roller ball movement enable these additional therapeutic functions without requiring completely separate devices, achieving multi-functionality while maintaining relatively simple design.
4Quantity of substance
If the applicator reservoir is enlarged to hold more product, then the applicator can reduce dipping frequency, but the applicator structure becomes more complex
Solution Approach 1:
The applicator is segmented into a reservoir portion that holds the cosmetic bulk and an application portion that interacts with the user. This segmentation allows the reservoir to be enlarged for higher product capacity while the application portion remains compact and simple. The reservoir portion can be designed with integrated structural features that provide both capacity and structural integrity without requiring additional complex components.

AI summary
An applicator head for applying a fluid product including a cosmetic, care, or pharmaceutical product onto the keratinous substrate. The applicator head includes an applying member elongated along a longitudinal axis. The applying member has tubular body with a closed proximal end and an open distal end. The applying member includes a sidewall and an interior longitudinal cavity having an opening at the open distal end of the applying member. The applying member, at its distal end portion, has a ball socket for rotatably mounting a spherical ball. The spherical ball can discharge the fluid product by rotation. The sidewall includes at least two through feed openings that allow filling of the internal longitudinal cavity with the fluid product when the applying member is dipped in the receptacle. A portion of the spherical ball protrudes from the ball socket beyond the open distal end of the applying member.
