Multidimensional Applicator Bristle Tuft for Crease Access
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
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
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
3Adaptability or versatility
If multiple brushes are used for different cosmetic applications, then specific functions are achieved, but device complexity increases
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

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.
