Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic applicators lack precision, flexibility, and freedom of movement, making it inconvenient to apply makeup or care products to all facial areas effectively.
Innovation Solution
A cosmetic applicator with a rotatable and adjustable roller applying member that can pivot to various angles, featuring a swivel connector and collar system, allowing for precise application and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional cosmetic applicators use a fixed applicator element, then the structure is simple, but the precision and flexibility of application are limited
Solution Approach 1:
The applicator element is designed to be movable relative to the stem through a swivel connector mechanism, allowing it to pivot and rotate. This dynamic capability enables the applicator to adapt to different facial contours and angles, significantly improving application precision while maintaining a relatively simple overall structure.
Solution Approach 2:
The applicator is divided into distinct functional segments: a fixed stem, a movable applicator element, and a swivel connector joining them. This segmentation allows independent optimization of each component - the stem provides structural support, the connector enables movement, and the applicator element delivers precise product application.
2Ease of operation
If conventional cosmetic applicators have limited movement range, then the device complexity is low, but the ease of operation and access to all facial areas is poor
Solution Approach 1:
The swivel connector enables the applicator element to pivot multiple degrees of freedom, allowing users to easily access hard-to-reach facial areas such as under the eyes, around the nose, and along the jawline. The dynamic adjustment capability significantly enhances ease of operation without requiring complex multi-joint mechanisms.
Solution Approach 2:
The applicator element can change its angular parameters relative to the stem through the swivel connector, allowing adaptation to different application angles and positions. This parameter variability improves ease of operation across different facial areas while keeping the mechanical structure simple.
3Adaptability or versatility
If conventional cosmetic applicators lack adjustability, then the device is simple, but the versatility for different cosmetic needs is limited
Solution Approach 1:
The swivel connector provides dynamic adjustability, allowing the applicator element to be positioned at various angles according to different cosmetic application needs. This single dynamic joint offers versatile adjustment capabilities without requiring multiple separate adjustment mechanisms, maintaining structural simplicity.
Solution Approach 2:
The movable applicator element with swivel connector provides multi-functional capability, enabling the same applicator to perform different application tasks at various angles and positions. This universality eliminates the need for multiple specialized applicators, enhancing versatility while keeping the device structure simple.

AI summary
A cosmetic applicator for applying cosmetic products to skin of a user. The cosmetic applicator includes a stem, a cap attached to a proximal end of the stem, a collar connected to a distal end portion of the stem, a swivel connector and a roller applying member. The swivel connector includes a spherical ball at its proximal portion and a shaft at its distal portion. The swivel connector is located at a distal end of the stem and connected to the stem with help of the collar. The roller applying member encloses the distal portion of the swivel connector's shaft and is rotatably connected to the shaft allowing rotation of the roller applying member in both clockwise and anticlockwise directions. The swivel connector enables the adjustment of the roller applying member to various angles relative to the stem's longitudinal axis.
