Dual-Surface Cosmetic Applicator With Resilient Projections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic applicators do not effectively massage the skin during product application, failing to provide a comprehensive sensorial experience.
Innovation Solution
A dual-surface applicator head assembly with a hollow sleeve and insertion member, featuring resilient elongated projections that create a compound application surface, providing a gentle multi-point massage by moving individually during product application, and a wiper unit for excess product removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional applicator head is used, then the applicator can apply cosmetic product, but it cannot massage the skin during application
Solution Approach 1:
The applicator head is segmented into multiple resilient projections that can independently deform and massage the skin while applying product. Each projection acts as an independent massaging element, allowing the overall structure to provide both application and massage functions simultaneously.
Solution Approach 2:
The applicator head is designed to perform multiple functions: applying cosmetic product and massaging the skin. The resilient projections enable the same component to serve both purposes, eliminating the need for separate tools and providing comprehensive sensorial experience.
2Adaptability or versatility
If the applicator head is made with resilient projections for massage, then skin massage function is added, but the device complexity increases
Solution Approach 1:
The massage function is merged with the product application function in a single applicator head assembly. The resilient projections are integrated directly into the applicator head structure, combining massaging capability with product dispensing rather than adding a separate massage mechanism.
Solution Approach 2:
The applicator head uses resilient projections that change their physical state (deforming and recovering) in response to contact with the skin. This parameter change enables the projections to adapt to skin contours and provide massage while maintaining structural integrity and product application capability.
3Productivity
If a wiper unit is added to remove excess product, then product distribution is improved, but the device complexity increases
Solution Approach 1:
The wiper unit is nested within the packaging device structure, fitting into the neck area of the receptacle. This nested configuration allows the wiper to be integrated into the existing device architecture without requiring a completely separate external mechanism, thereby limiting the increase in overall device complexity.
Solution Approach 2:
The wiper unit acts as an intermediary component between the product reservoir and the applicator head. It mediates the product flow by removing excess product before it reaches the applicator head, improving product distribution efficiency without requiring complex control systems.
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
The applicator effectively applies products while massaging the skin, offering a sensorial experience and efficiently managing product distribution with the wiper unit.
Implementation Method 1
The plurality of elongated projections are resilient in nature and are capable of moving independent of each other when subjected to an external stimulus such as pressure, temperature, electricity, magnetism, light, radio frequency, micro-wave or radiation.

AI summary
A cosmetic applicator for applying a cosmetic or care product includes an applicator head assembly comprising a first application surface and a second application surface. The first application surface is a continuous application surface whereas the second application surface is a discontinuous application surface. The second application surface is a collection of a plurality of application surfaces, wherein each of the application surfaces has an area smaller than an area of the continuous application surface. The applicator head assembly comprises a hollow sleeve and an insertion member which is configured to be received and retained within the hollow sleeve. The insertion member includes a plurality of elongated projections which defines the second application surface whereas the first application surface is defined on a portion of the hollow sleeve.
