Solution Overview

Problem

Conventional cosmetic brushes are inadequate for applying products to creases and deep lines on the face, requiring users to stretch their skin and often necessitating multiple brushes for different applications.

Innovation Solution

A multifunctional brush with a bristle tuft featuring contoured bristles, including angled surfaces and a ridge, allowing for precise application to various facial areas without skin stretching, including creases and lines, and capable of applying multiple types of cosmetic products.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional brushes with rounded or flat shapes are used, then they can apply products to flat surfaces, but they cannot access creases or deep lines on the face

Engineering Contradiction:
Improveaccess to facial surfacesVSAvoidapplicability to different facial areas
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The brush head is segmented into multiple distinct surfaces (flat top surface, angled side surfaces, and a pointed tip) that can be used for different applications. This segmentation allows each part of the brush to access and apply product to different facial areas including flat surfaces, creases, and deep lines without requiring multiple separate brushes

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The brush transitions from conventional two-dimensional flat or rounded shapes to a three-dimensional multidimensional structure with surfaces extending in multiple directions and angles. This dimensional expansion enables the brush to access creases and deep lines on the face that conventional flat brushes cannot reach

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If users stretch the skin in crease areas to allow brush access, then conventional brushes can apply product, but skin distortion occurs

Engineering Contradiction:
Improveproduct application to creasesVSAvoidskin distortion
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Instead of requiring the user to stretch the skin to accommodate the brush, the brush is designed to accommodate itself to the skin's natural contours. The multidimensional brush head with its angled surfaces and pointed tip can enter creases and deep lines without requiring skin manipulation, eliminating the harmful stretching action

Inventive Principle:
Principle #13The other way round (Inversion)

3Adaptability or versatility

If multiple brushes are used for different cosmetic applications, then specific functions are achieved, but device complexity increases

Engineering Contradiction:
Improvecosmetic application functionalityVSAvoidnumber of brushes required
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The brush is designed as a universal multifunctional tool with a multidimensional head that can perform multiple cosmetic applications including applying loose powder, setting powder, contouring, and creating texture. The various surfaces (flat, angled, and pointed) allow a single brush to replace multiple specialized brushes, reducing device complexity while maintaining versatility

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An applicator (100), such as a brush or other device, for applying products to a surface, such as the skin of a person. The applicator (100) includes a handle (102) and a bristle tuft (104) connected to the handle (102). The bristle tuft (104) may include a plurality of contoured bristles (110) that define multiple surfaces for applying products. For example, the bristle tuft may include a first angled surface (112) extending upwards from a first side of the bristle tuft, a second angled surface (114) extending upwards from a second side of the bristle tuft, and a ridge (116) defined at an intersection of the first angled surface and the second angled surface.
