Petal Applicator Head with Internal Cavity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic applicators require frequent dipping into the product reservoir to apply cosmetic or pharmaceutical products to keratinous surfaces, such as lips, skin, and under-eye areas, and lack a design that efficiently distributes and massages the product effectively.
Innovation Solution
A cosmetic applicator head with a distal end featuring multiple petals and grooves that enclose a cavity, providing a larger surface area for application and distribution, and a shank member for easy attachment to a stem, allowing for a more substantial product application without frequent re-dipping, and is aesthetically pleasing and economical to manufacture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional applicators are used, then the applicator can be simple in structure, but the applicator requires frequent dipping into the product reservoir
Solution Approach 1:
The patent implements an internal passive reservoir nested within the applicator body, creating a multi-layered structure where the reservoir is contained inside the applicator. This nesting allows the applicator to store cosmetic product internally, eliminating the need for frequent dipping into the main reservoir while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent transitions from a traditional single-point application interface to a three-dimensional applicator head with multiple wings extending in different directions. This dimensional expansion creates multiple mass storage spaces and increases the surface area for product application, reducing the frequency of re-dipping while keeping the base structure simple.
2Ease of manufacture
If conventional applicators are used, then the applicator is easy to manufacture, but the applicator has limited product storage capacity
Solution Approach 1:
The internal passive reservoir is nested within the applicator body, creating an integrated structure that increases product storage capacity without requiring separate components or complex assembly processes. This nesting approach maintains manufacturing simplicity while significantly increasing the quantity of cosmetic product that can be stored and applied.
Solution Approach 2:
The applicator head with multiple wings extending in different directions creates three-dimensional mass storage spaces, increasing the volume available for product storage. This dimensional expansion allows greater product capacity to be achieved through geometric configuration rather than increasing the overall applicator size or complexity.
3Device complexity
If conventional applicators are used, then the applicator has a simple design, but the applicator lacks surfaces suitable for massaging the cosmetic product
Solution Approach 1:
The patent introduces multiple wings extending in different directions from the applicator body, creating a three-dimensional structure with multiple surfaces. These wings provide extended contact areas that can glide across the skin in various directions, enabling massaging action. The complex geometry is achieved through extrusion molding, maintaining manufacturing simplicity while enhancing operational functionality.
Solution Approach 2:
The applicator head with multiple wings serves multiple functions: it stores product in its mass storage spaces, applies product through its extended surfaces, and massages the skin through its geometric configuration. This multi-functionality is integrated into a single structure that can be manufactured using standard extrusion molding processes.

AI summary
An applicator head for applying a 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 includes at least one sidewall and a distal end face that is inclined. The at least one sidewall has an extended portion that extends beyond the distal end face of the applying member. The extended portion peripherally encloses the distal end face to define a cavity at the distal end portion of the applying member. The cavity opens upwardly at a distal end of the applying member and has a closed bottom end that is defined by the distal end face of the applying member. The cavity is suitable for holding a cosmetic product. The extended portion is in form of multiple petals that surround the distal end face.
