Rotatable Cosmetic Applicator Ball and Beads for Skin Massage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic applicators are limited to only applying cosmetics and lack the functionality for massage due to non-rotatable massaging elements.
Innovation Solution
A cosmetic applicator design featuring a shaft with a rotatable ball and beads, allowing for both cosmetic application and massage by incorporating a socket and boss mechanism for smooth rotation, enabling the applicator to effectively massage the skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the massaging elements are made non-rotatable, then the applicator can apply cosmetics, but it cannot provide massage function
Solution Approach 1:
The patent applies the dynamics principle by making the massaging elements (ball and beads) rotatable relative to the shaft. The ball is rotationally inserted in the socket and can rotate freely, while the beads are rotationally extending around the slender section. This rotational capability transforms the static applicator into a dynamic one that can both apply cosmetics and provide massage through rolling motion, thereby resolving the contradiction between functionality and ease of operation.
2Adaptability or versatility
If the ball is rotationally inserted in the socket, then the applicator can massage, but the structure becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the applicator into distinct functional components: the shaft, the socket, the ball with front and rear portions, and the beads. Each component has a specific function - the shaft for structural support, the socket for rotational insertion, the ball for massage, and the beads for additional massaging. This segmentation allows the complex massage function to be achieved through simple, modular parts that are easy to manufacture and assemble.
3Ease of operation
If the beads are rotationally extending around the slender section, then the applicator can massage effectively, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies parameter changes by specifying that the beads are rotationally extending around the slender section of the shaft, allowing them to rotate freely. This rotational parameter change enables the beads to adapt to different skin contours and provide effective massage. The design accepts a certain range of manufacturing tolerances in the rotational alignment, as the functional requirement is met as long as the beads can rotate around the shaft, rather than requiring precise fixed positioning.

AI summary
A cosmetic applicator includes a shaft, a ball and at least one bead. The shaft includes a slender section, an enlarged section formed at an end of the slender section, a socket formed at an end of the enlarged section, and a boss extending from an internal face of the socket. The ball includes a front portion extending from the socket and a rear portion rotationally inserted in the socket and abutted against the boss. The at least one bead is rotationally extending around the slender section of the shaft.
