False Eyelash Axial Thread Folded-Back Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for manufacturing false eyelashes require expert skills and result in uneven placement of eyelash materials, leading to unattractive sparse and dense areas, discomfort, and deformation, making them difficult to wear naturally and comfortably.
Innovation Solution
The development of false eyelashes with a structure featuring top and bottom eyelash materials folded back adjacent to an axial thread, alternately placed and fixed using a knit structure or lock thread, providing even distribution and dimensional stability, and made from materials like polyester or natural fibers with optional antibacterial agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional manual binding method is used, then expert skills can be utilized, but the eyelash materials cannot be placed evenly resulting in sparse and dense areas
Solution Approach 1:
The eyelash materials are divided into top eyelash materials and bottom eyelash materials positioned on opposite sides of the axial thread. This segmentation allows for systematic and even distribution of materials, eliminating the randomness and unevenness inherent in traditional manual binding methods.
Solution Approach 2:
The folded-back parts of adjacent eyelash materials are pre-fixed together before being attached to the axial thread. This preliminary action ensures proper spacing and alignment is established in advance, preventing sparse and dense areas during the final assembly process.
2Reliability
If traditional manual binding method is used, then flexibility in material selection is maintained, but the ear part deforms and comfort is reduced
Solution Approach 1:
Instead of fixing eyelash materials to the axial thread directly at their bases, the folded-back parts of adjacent eyelash materials are fixed together first, and then this pre-assembled structure is attached to the axial thread. This inversion of the binding sequence ensures uniform distribution and prevents deformation of the ear part, improving both dimensional stability and wearing comfort.
3Strength
If eyelash materials are bound tightly, then structural integrity is improved, but the appearance becomes less natural due to uneven placement
Solution Approach 1:
The binding structure is designed with different functional zones: the folded-back parts are tightly bound together to ensure structural integrity, while the eyelash materials extend outward with sufficient spacing to maintain natural appearance. This local differentiation of binding tightness resolves the contradiction between strength and aesthetics.
Solution Approach 2:
The false eyelash comprises a composite structure of top eyelash materials and bottom eyelash materials alternating on opposite sides of the axial thread. This composite arrangement creates a more natural, multidimensional appearance while the folded-back parts provide strong binding points for structural integrity.

AI summary
In an embodiment, false eyelashes contain an axial thread 10 and eyelash materials which include multiple top eyelash materials 21 and multiple bottom eyelash materials 22 positioned above and below the axial thread, respectively. The top and bottom eyelash materials each have a structure where one eyelash material is folded where folded-back parts A, B are adjacent to the axial thread; the top and bottom eyelash materials, each having a folded-back part, are placed in rows in the length direction of the axial thread, while being fixed vertically; the top and bottom eyelash materials are alternately placed from one end to the other end of the axial thread; the folded-back parts of the adjacent top and bottom eyelash material are fixed together; and each fixed folded-back part is fixed to the axial thread to form an ear part C, thereby fixing the folded-back part to the axial thread.
