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
Solution Approach 1:
The patent replaces manual mechanical application with an automated micro-robotic system that uses magnetic fields for positioning and control. The micro-robot incorporates magnets for precise positioning, a wire comb mechanism for gripping, and magnetic actuators for controlled movement, eliminating the need for manual dexterity while achieving high precision in eyelash application.
Solution Approach 2:
The micro-robot is designed to autonomously perform the eyelash application process without requiring continuous human intervention. The system self-navigates to the target location, self-grips the eyelash using the wire comb mechanism, and self-applies it to the eyelid, thereby improving precision while maintaining operational simplicity through automation.
2Manufacturing precision
If existing application methods are used, then the process is quick, but customization and precision are lacking
Solution Approach 1:
The micro-robot employs dynamic control through magnetic field manipulation to achieve rapid yet precise positioning. The magnetic actuators enable the robot to quickly adjust its position and orientation on the flexible PCB substrate, while the wire comb mechanism dynamically grips and releases the eyelash, allowing for both speed and precision in the application process.
Solution Approach 2:
The system utilizes changes in magnetic field strength and direction to control the micro-robot's movement and gripping force. By varying magnetic parameters, the system can quickly transition between different states (movement, positioning, gripping, releasing) without mechanical adjustment, thereby achieving high positioning precision while minimizing application time.
3Reliability
If traditional gripping mechanisms are used, then the structure is simple, but gripping precision and reliability are insufficient
Solution Approach 1:
The wire comb acts as an intermediary gripping mechanism between the micro-robot's magnetic actuator and the eyelash. The comb teeth provide a distributed contact interface that reliably grasps the eyelash without requiring direct mechanical contact from the actuator, thereby improving gripping reliability while keeping the overall mechanism compact and manageable in complexity.
4Measurement precision
If manual positioning is used, then the setup is simple, but positioning accuracy and customization are poor
Solution Approach 1:
The system replaces manual positioning with automated magnetic field-based positioning control. The micro-robot uses magnetic actuators to precisely navigate to the target location on the flexible PCB substrate, and the system can be controlled via software or automated sequences, achieving high positioning accuracy while maintaining ease of operation through automated control rather than manual manipulation.
