Cosmetic Applicator With Curved Segments for Dual-Use Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic product applicators are inadequate for both applying products over large areas and performing precise retouching, as they are either too bulky for broad application or lack the necessary precision for detailed application.
Innovation Solution
A cosmetic product applicator with a flexible application body featuring multiple curved segments and flocking, allowing for dual-directional application by utilizing two distinct hollow areas for broad and precise product distribution, enabling versatile use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the application body includes a first curved segment with a hollow area for receiving cosmetic product, then the applicator can apply product over a large surface area, but the applicator becomes less suitable for precise retouching or detailed application
Solution Approach 1:
The application body is divided into multiple functional segments: a first curved segment with a hollow area for broad application, a second curved segment for precise application, and a third end segment. This segmentation allows different portions of the applicator to serve different purposes - the hollow area segment for covering large surfaces and the end segment for detailed retouching work.
Solution Approach 2:
Different segments of the application body are designed with different geometries and properties suited to their specific functions. The first segment has a hollow area optimized for broad coverage, while the third end segment has a geometry optimized for precise application. This local differentiation of quality allows the single applicator to perform both broad and precise application tasks effectively.
2Productivity
If the application body is designed for broad area application, then it covers large surfaces effectively, but it lacks the precision needed for retouching
Solution Approach 1:
The application body is designed as a multi-functional tool that can perform both broad area application and precise retouching. By incorporating multiple segments with different geometries (hollow area for coverage, end segment for precision), the single applicator serves multiple functions that would traditionally require separate tools, making it universal for both productivity-oriented and precision-oriented tasks.
3Device complexity
If the applicator uses a single application body design, then the structure is simple, but it cannot perform both broad application and precise retouching effectively
Solution Approach 1:
The application body is segmented into distinct functional zones (first curved segment with hollow area, second curved segment, third end segment) that can be manufactured as a single integrated piece. This segmentation provides versatility for different application tasks while maintaining relative structural simplicity through single-piece construction, avoiding the need for multiple separate components.

AI summary
This applicator comprises a tip (22) with a central axis (A-A') and a product application body (24), in a single piece with the tip (22). The body (24) includes a first curved segment (40) with a local axis moving away from the central axis (A-A') seen in a plane parallel to an axial median plane of the applicator. The body (24) has a second curved intermediate segment (42) with a local axis approaching the central axis (A-A'), and defining, with the first segment (40), a first hollow area.The body (24) has a third end segment (44) defining, with the second intermediate segment (42), a second hollow area (58) opposite the first hollow area.
