Eyelash Curler Comb Member for Root Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyelash curlers fail to effectively separate eyelashes at their roots, leading to adhesion and inadequate curling, especially in forming uniform shapes.
Innovation Solution
An additional member with tooth-shaped portions attached to the eyelash curler, which are spaced at intervals and extend upward to separate eyelashes at their roots, preventing adhesion and allowing for beautiful curling into fan shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional eyelash curler is used to curl eyelashes, then eyelashes can be curled, but eyelashes may adhere to each other or stand upright instead of being properly aligned
Solution Approach 1:
The curling surface is segmented into multiple tooth-shaped portions spaced at intervals, which divide and align individual eyelashes separately rather than pressing them as a group. This segmentation allows each eyelash to be positioned independently, preventing adhesion and ensuring consistent curling results.
Solution Approach 2:
The tooth-shaped portions act as intermediary elements between the pressing members, providing a structured interface that guides and aligns eyelashes before curling. These teeth serve as a mediating structure that organizes the eyelashes in the desired configuration during the curling process.
2Manufacturing precision
If eyelash arrangement means is added to disperse and align eyelashes, then eyelash alignment is improved, but the device structure becomes more complex
Solution Approach 1:
The alignment function is merged with the curling function by integrating tooth-shaped portions directly onto the pressing members. This combination eliminates the need for separate alignment mechanisms, as the same structural elements that press the eyelashes also provide the alignment through their tooth geometry and spacing.
Solution Approach 2:
The pressing members are given multi-functionality by incorporating tooth-shaped portions that simultaneously perform both alignment and curling operations. This universal design allows a single component to execute multiple functions, reducing the overall device complexity while maintaining effective eyelash alignment and curling.
3Shape
If tooth-shaped portions are spaced at certain intervals, then eyelashes can be curled into uniform fan shapes, but the manufacturing precision requirements increase
Solution Approach 1:
The spacing interval between tooth-shaped portions is optimized to match the natural density and dimensions of eyelashes. By setting the interval parameter appropriately, the design achieves uniform fan-shaped curling without requiring extremely tight manufacturing tolerances, as the spacing naturally accommodates individual eyelash variations.

AI summary
Embodiments of the present invention provide an eyelash curler capable of separating eyelashes from each other at roots thereof and of beautifully curling eyelashes. The eyelash curler 1 has a pair of frame portions 12 and 12 extending in a vertical direction, a movable member 60 that is movable in the vertical direction along the pair of frame portions 12 and 12, a stationary member 50 fixed above the movable member 60, and an elastic member 70 placed on the movable member 60. The eyelash curler 1 has arm members 10 and 20 operable to move the movable member 60 upward to bring the contact area 70A of the elastic member 70 into contact with the stationary member 50 and a comb member 80 attached to the movable member 60. The comb member 80 includes an attachment portion 81 attached to a front surface of the movable member 60, a bridge portion 82 extending from the attachment portion 81 to near the contact area 70A of the elastic member 70, and a plurality of tooth-shaped portions 83 extending upward from portions of the bridge portion 82 that are located near the contact area 70A of the elastic member 70. The tooth-shaped portions 83 are spaced at certain intervals in a horizontal direction.
