Liquid-Dispensing Applicator With Rotatable Massage Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic applicators with massage heads have poor application uniformity due to fixed application angles that do not adjust to facial contours, and phototherapy lamp panels are difficult to install and maintain.
Innovation Solution
An applicator with a rotatable and bendable liquid discharge head body, featuring an elastic piece that allows 360-degree rotation and tilting, and a detachable massage head design for easy installation and maintenance of stimulation elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the liquid discharge head body is fixed with a fixed angle structure, then the device structure is simple and stable, but the application effect is poor because it cannot adjust to facial contours
Solution Approach 1:
The liquid discharge head body is designed with dynamic flexibility, allowing it to bend and rotate freely under the action of external forces (such as hand operation or facial movement). This dynamic structure enables the head body to adapt its angle and position to match different facial contours, transforming a static fixed structure into an adaptive dynamic one that improves application effectiveness.
Solution Approach 2:
The elastic piece changes its physical state (compression and expansion) in response to external forces, allowing the liquid discharge head body to vary its angle and position. This parameter change mechanism enables the structure to adjust between different configurations without requiring complex mechanical joints, resolving the contradiction between adaptability and structural simplicity.
2Ease of repair
If the phototherapy lamp panel is bonded and fixed on the inner wall of the massage head, then the installation is stable, but the installation and positioning is complicated and maintenance is inconvenient
Solution Approach 1:
The massage head is divided into separable components: the massage head body and the phototherapy lamp panel are designed as independent, detachable parts. This segmentation allows the lamp panel to be easily removed and replaced for maintenance or replacement, while still maintaining stable installation during use through the elastic piece connection mechanism.
Solution Approach 2:
The elastic piece provides a dynamic connection that allows for easy attachment and detachment of the phototherapy lamp panel. The elastic piece can be compressed to release the panel and expanded to secure it, providing both stable installation during use and convenient maintenance access when needed.

AI summary
Embodiments of the present invention provide an apparatus for applying a liquid from a bottle and a massage head. The apparatus comprises a housing having a liquid inlet end configured to be connected to a liquid storage bottle, a first liquid discharge channel in the housing and a liquid discharge head body having a second liquid discharge channel. The first liquid discharge channel is connected to the second discharge channel through a drain pipe. An elastic piece is positioned between the housing and the liquid discharge head body. The elastic piece compress or decompress under an action of an external force. The elastic piece allows 360 degree rotation to the applicator and applicator bends at a predetermined angle.
