Artificial Nail Guiding Grooves for Pattern Drawing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing artificial nails lack effective guiding structures that are resistant to polishing, leading to difficulties in drawing patterns or installing decorative parts, and result in unreliable bonding of nail varnish.
Innovation Solution
The artificial nail features a top surface with recessed guiding grooves, specifically a first and second curved groove, designed to guide pattern drawing or decorative piece mounting, while being resistant to abrasion and easy to fill with a sealing layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If guide lines are provided on the surface of artificial nails, then users can be guided to draw patterns or install decorative parts, but the guide lines are easily polished off during the polishing step
Solution Approach 1:
The guide lines are segmented into raised portions and recessed portions along their length. This segmentation creates a tactile structure where the raised portions remain visible and tactile after polishing, while the recessed portions can be filled with sealing material to maintain the guidance function throughout the polishing process.
Solution Approach 2:
The guide lines are given a three-dimensional structure with varying heights (raised and recessed portions) rather than remaining flat on the surface. This dimensional change allows the guide lines to withstand polishing better, as the raised portions survive polishing while still providing tactile guidance.
2Reliability
If the surface is polished to improve bonding of nail varnish, then bonding reliability improves, but the guide lines are removed
Solution Approach 1:
The guide lines are pre-formed with raised and recessed portions before the polishing step. This preliminary structuring ensures that even after polishing removes surface material, the raised portions of the guide lines remain intact to provide continued guidance during pattern drawing and decorative installation.
Solution Approach 2:
The recessed portions of the guide lines are prepared in advance to be filled with sealing material. This beforehand preparation cushions against the loss of guide lines during polishing, as the sealing material fills the recessed areas and maintains the guidance function throughout the polishing process.
3Ease of operation
If guide lines are provided to guide pattern drawing, then ease of operation improves, but the aesthetic appearance deteriorates due to visible guide lines after sealing
Solution Approach 1:
Different portions of the guide lines have different heights (raised vs. recessed), creating local quality variations. The recessed portions are specifically designed to be filled with sealing material, while the raised portions provide tactile guidance. This local differentiation allows the guide lines to function during application while becoming aesthetically pleasing after sealing, as the filled recessed portions blend with the surrounding surface.

AI summary
An artificial nail has a top surface, a portion of the top surface is recessed inwardly to form a plurality of guiding grooves, and the plurality of guiding grooves are used for guiding a user to draw a pattern or mount a decorative piece on the top surface of the artificial nail. The artificial nail comprises: a first edge configured to be disposed near a natural cuticle of the real nail; a second edge opposite to the first edge; a third edge and a fourth edge that are connected between the first edge and the second edge and are spaced apart from each other. The plurality of guiding grooves comprise a first curved groove and a second curved groove; each of the first curved groove and the second curved groove has one end disposed near the third edge and the other end disposed near the fourth edge.
