Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for applying eyelashes, such as false eyelashes, are inefficient and lack precision in separating and applying individual lashes, often resulting in uneven application.
Innovation Solution
A micro-robot crane system comprising a back micro-robot and a front micro-robot, each with a plurality of magnets and a separation arm, that work together to separate and apply eyelashes by sliding or levitating over a flexible printed circuit board (PCB) substrate, using linear actuators to adjust pitch, yaw, and roll for precise application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual methods are used for applying eyelashes, then the process is simple, but precision and efficiency are poor resulting in uneven application
Solution Approach 1:
The patent replaces manual mechanical manipulation with an automated micro-robot system that uses magnetic fields for actuation. The micro-robot crane incorporates magnets for movement control and a separation arm with separating tips for precise eyelash manipulation, eliminating the imprecision of manual application while maintaining operational simplicity through automated control.
Solution Approach 2:
The application system is divided into distinct functional modules: a back micro-robot for positioning, a front micro-robot for separation arm control, a separation arm with multiple separating tips for individual lash handling, and a magnetic actuation system. This segmentation allows each component to perform its specific function with high precision while the overall system remains manageable through modular design.
2Productivity
If traditional eyelash application methods are used, then the equipment is simple, but productivity and efficiency are low
Solution Approach 1:
The micro-robot system is designed to autonomously perform the eyelash application process. The magnetic actuation system automatically controls the movement of the back and front micro-robots, the separation arm positioning, and the application sequence without requiring continuous manual intervention, thereby significantly improving productivity while the automated control manages the system complexity.
Solution Approach 2:
The system performs preliminary actions by first using the back micro-robot to position the separation arm near the target eyelash, then the front micro-robot activates the separation mechanism before the actual application. This pre-positioning and pre-separation sequence optimizes the main application action, improving overall efficiency while organizing the complex operations into manageable stages.
3Manufacturing precision
If manual eyelash separation is performed, then the process is straightforward, but uniformity and aesthetic results are inconsistent
Solution Approach 1:
The separation arm is equipped with multiple separating tips of different shapes and sizes, each optimized for specific eyelash characteristics and application locations. The magnetic actuation system provides localized control over each tip's movement and positioning, ensuring uniform application across different areas of the eyelid while the specialized tips handle variations in lash thickness and curvature.
Solution Approach 2:
The micro-robot system employs dynamic control through magnetic field modulation to adjust the separation arm's movement in real-time. The back and front micro-robots can independently adjust their positions and speeds to accommodate variations in eyelash density, length, and curl, ensuring consistent application results across different eye regions while managing the dynamic complexity through coordinated control.
