Lash Extension Base Concealment via Segmented Hair Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lash extensions often have a visible base that disrupts the natural appearance when applied to natural eyelashes, as the base thickness can be readily observed, ruining the illusion of real lashes.
Innovation Solution
A lash extension design featuring multiple hairs with a base located towards the first end, allowing the hairs extending from the base to align with natural lashes, thereby blending the hairs before the base with the natural eyelashes, which helps conceal the base for a more natural appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the base is made thicker to provide structural support, then the structural integrity is improved, but the natural appearance deteriorates because the base becomes readily observed
Solution Approach 1:
The patent divides the lash extension into multiple hair segments (first segment above the base, second segment below the base) rather than a single continuous hair. This segmentation allows the base to be positioned within the lash line and concealed by natural lashes, while each segment maintains sufficient length and structural integrity for durability.
Solution Approach 2:
The patent positions the base in a different spatial dimension - specifically, within the lash line rather than at the visible outer edge. By having hairs extend above and below the base, the base is relocated to a concealed position along the lash line, making it imperceptible from the front view while maintaining structural support.
2Ease of operation
If the base is positioned at the outer edge for easy attachment, then the ease of operation is improved, but the natural appearance deteriorates because the base cannot be concealed
Solution Approach 1:
Instead of positioning the base at the outer edge where it would be visible, the patent inverts the conventional approach by positioning the base within the lash line. The hairs extend in both directions from the base, effectively hiding it from view while maintaining attachment functionality.
3Object-affected harmful factors
If hairs are trimmed to blend with natural lashes, then the natural appearance is improved, but the structural integrity deteriorates because the base may become exposed
Solution Approach 1:
The patent segments the hair into multiple parts with the base positioned between them. This allows the first and second hair segments to be trimmed to appropriate lengths for blending with natural lashes, while the base remains protected and concealed within the lash line, maintaining both appearance and structural integrity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances the natural blending of lash extensions with natural eyelashes, effectively concealing the base and creating a more realistic appearance both above and below the base.
Implementation Method 1
the base may be heat fused so that the base is thin

AI summary
This disclosure discloses a lash extension comprising: a first hair having a first proximal end and a first distal end; a second hair having a second proximal end and a second distal end; and a base intersecting the first hair between the first proximal end and the first distal end and the second hair between the second proximal end and the second distal end such that a first segment of the first hair extends between the base and the first proximal end and a second segment of the second hair extends between the base and the second proximal end.
