Multi-Nozzle Spray Disc Layout for Versatile Automatic Makeup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing makeup application technologies lack versatility, ease of use, and safety for unskilled individuals, and there is a need for an automatic makeup mechanism that can apply various cosmetics effectively.
Innovation Solution
A spray disk with multiple nozzles and partitions, each containing a liquid tank and air inlet, is used in an automatic makeup machine, controlled by a disk head and controller for precise application of cosmetics on the user's face, with features like modularized partitions and customizable liquid tanks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a spray disk with multiple nozzles and partitions is used, then versatility in applying multiple cosmetics is improved, but device complexity increases
Solution Approach 1:
The spray disk is divided into multiple partitions, with each partition containing a separate liquid tank for different cosmetics. This segmentation allows the device to handle multiple cosmetic products simultaneously while maintaining organized separation, resolving the contradiction between versatility and complexity by structuring the system into manageable functional units
Solution Approach 2:
The spray disk design integrates multiple nozzles, liquid tanks, and partitions into a single device that can apply various cosmetics (foundation, concealer, blush, etc.) through one unified mechanism. This multi-functionality approach enables the device to perform multiple makeup application functions without requiring separate tools for each cosmetic type
2Productivity
If compressed air is used to spray liquid through nozzles, then productivity and application speed are improved, but control precision may worsen
Solution Approach 1:
The system incorporates sensors and controllers that monitor the spray process in real-time, detecting parameters such as spray pattern, coverage uniformity, and liquid flow rate. This feedback mechanism allows the controller to adjust compressed air pressure and nozzle operation dynamically, maintaining precision despite the high-speed productivity enabled by compressed air spraying
Solution Approach 2:
The patent utilizes compressed air (pneumatics) to atomize and deliver cosmetics through the nozzles. By carefully controlling the pneumatic pressure and flow characteristics, the system achieves both high-speed application and precise control over spray patterns, coating uniformity, and material distribution across the skin surface

AI summary
A spray disk includes multiple nozzles at an outer perimeter of the spray disk, a center hole, and multiple partitions. The partitions are arranged around the center hole and have the center hole as an inner perimeter. Each partition includes an air inlet to receive compressed air, a liquid tank to store a liquid, and a corresponding nozzle from which to spray the liquid with the compressed air. The spray disk can be used in an automatic makeup machine.
