Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing cosmetic applicators lack the ability to easily produce devices that offer new treatment or makeup effects while being easy to manufacture and allowing for different surface treatments on spatially separated surfaces.

Innovation Solution

A cosmetic applicator with an applicator head comprising two parts connected by a hinge, where one part has a cavity and the other is engaged within, allowing for one surface to be visible while the other combines flocked fibers and molded application elements, such as tines, providing distinct application capabilities on each side.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a cosmetic applicator has a single unified applicator head, then the structure is simple and easy to manufacture, but it cannot provide different surface treatments on spatially separated surfaces for distinct application capabilities

Engineering Contradiction:

Improvedifferent surface treatmentsVSAvoidapplicator structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The applicator head is divided into two separate parts (first part and second part) that can be spatially separated during manufacturing to receive different surface treatments, then connected via a hinge to form a unified applicator head with distinct application capabilities on each side

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If two parts are connected by a hinge allowing movement, then the applicator can offer distinct application capabilities on each side, but the structural integrity and stability are reduced

Engineering Contradiction:

Improvedistinct application capabilitiesVSAvoidstructural integrity

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The hinge connection allows the two parts to move relative to each other, enabling the applicator to adapt between different application modes while maintaining structural integrity through the controlled articulation mechanism

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the applicator head is formed in an interim configuration with spatially separated surfaces, then different surface treatments can be applied, but the manufacturing process becomes more complex

Engineering Contradiction:

Improvedifferent surface treatmentsVSAvoidproduction process

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The two parts are prepared in advance in an interim configuration where different surface treatments (such as flocking on one part and molding on the other) can be applied independently before final assembly through the hinge connection

Inventive Principle:

Principle #10Preliminary action

AI summary

A cosmetic applicator for applying a cosmetic or care product includes an applicator member retained at a distal end of a stem. The applicator member comprising an applicator head including: a first part having a cavity which is not a through cavity, and a second part that is connected to the first part by a hinge and is at least partially engaged in the housing of the first part. The applicator head defines two opposite main faces and wherein one type of application elements are accessible for use on the first face and a second type of application elements are accessible for use on second face of the applicator head.
