Solution Overview

Problem

Conventional lip make-up applicators are difficult to use for local applications and changing lip lines due to their massive shape and uniform configuration, which limits the variety of application feelings and usage purposes.

Innovation Solution

A tip applicator with a capture recess that varies in depth and width along its length, featuring multiple capture areas with different cosmetic capture amounts, and a support portion that prevents bending, allowing for controlled cosmetic application and various application feelings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the applicator has a massive shape and uniform configuration, then the capture function is improved, but the adaptability for local application and changing lip lines deteriorates

Engineering Contradiction:
Improvecosmetic capture amountVSAvoidadaptability for local application
Core Design Contradiction:
Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The applicator tip is divided into multiple regions with different capture amounts, where each region has specific depth and width characteristics. The first region has larger depth and width for general application, while the second region has smaller depth and width for precise local application, allowing different parts of the same applicator to serve different functions

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The applicator tip is segmented into multiple distinct regions along its length, with each region having independently controlled dimensions. This segmentation allows the applicator to provide both broad coverage and precise detailing capabilities within a single tool

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If the application member has same configuration on front side, lateral sides and rear side, then the manufacturing simplicity is improved, but the ease of operation for various usage purposes deteriorates

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidvarious use feelings
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

Different regions of the application member are given different configurations and materials tailored to their specific functions. The front side has characteristics optimized for cosmetic capture, while the rear side and lateral sides have configurations optimized for application feel and user comfort, with each region having unique depth, width, and material properties

Inventive Principle:
Principle #3Local quality
