Artificial Eyelash Trimming via Additive Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing fake eyelashes often result in unnatural-looking products due to the bundling of eyelashes in knots, which limits design possibilities and increases production costs.
Innovation Solution
A trimming system for artificial eyelashes featuring an eyelash band with individually positioned and spaced artificial eyelashes, produced using additive manufacturing, such as 3D printing, to create a more natural appearance and simplify production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If artificial eyelashes are bundled in knots to form fake eyelash arches, then production is simplified and multiple lashes are held together, but the appearance becomes unnatural and design possibilities are limited
Solution Approach 1:
The invention divides the traditional bundled eyelash structure into individual eyelashes that are separately attached to the band at specific intervals, rather than grouping them in knots. This segmentation allows each eyelash to be positioned independently, creating a more natural appearance while maintaining production efficiency through systematic attachment methods
Solution Approach 2:
The invention uses additive manufacturing (3D printing) to create the eyelash band with integrated eyelash structures, copying the natural growth pattern of eyelashes where each lash emerges separately from the band at regular intervals, rather than bundling them together as in traditional methods
2Ease of manufacture
If artificial eyelashes are bundled in knots, then production cost is reduced through simplified manufacturing, but design possibilities are limited
Solution Approach 1:
The invention enables dynamic design flexibility by allowing individual eyelashes to be positioned at variable intervals and orientations along the band, rather than being fixed in rigid bundles. This dynamic positioning capability, achieved through additive manufacturing, allows for diverse design patterns while maintaining cost-effective production
Solution Approach 2:
The invention changes the fundamental parameter of eyelash arrangement from bundled groups to individually spaced positions on the band. This parameter change, implemented through additive manufacturing processes, enables varied design configurations including different spacing patterns, lengths, and orientations without significantly increasing production complexity or cost
3Device complexity
If multiple artificial eyelashes are attached to a single knot, then the structure is simplified, but the look becomes unnatural compared to natural lash growth
Solution Approach 1:
The invention segments the eyelash attachment structure so that each eyelash is individually attached to the band at separate locations, mimicking natural eyelash growth where each lash emerges independently from the lash line, rather than being grouped in bundles at a single knot location
Solution Approach 2:
The invention copies the natural anatomical structure of the eyelash line by creating a band with multiple individual attachment points spaced at regular intervals, replicating how natural eyelashes grow from pores along the eyelid margin, thereby achieving a more realistic appearance
