One-Touch Artificial Nail Adhesive Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional double-sided adhesive tapes struggle to maintain adhesion on curved artificial nails, leading to bubble formation, wrinkles, and a 'pop-up' phenomenon where the release tape detaches, resulting in a decreased adhesive area and potential sticking of impurities.
Innovation Solution
A one-touch artificial nail design featuring a nail body with a double-sided adhesive tape body and release tape, where the adhesive tape has non-connecting portions with cutting lines and a larger release tape area, allowing air discharge and preventing wrinkles, while the release tape's greater area minimizes impurity sticking and maintains adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a planar double-sided adhesive tape is used on a curved artificial nail, then the adhesive tape can be easily manufactured, but air enters between the tape and nail to form bubbles and wrinkles, reducing adhesive area and force
Solution Approach 1:
The adhesive tape body is divided into multiple non-connecting portions separated by first cutting lines, allowing each segment to independently conform to the curved surface of the artificial nail without forming bubbles or wrinkles, while maintaining overall adhesive integrity through connecting portions
2Ease of manufacture
If the adhesive tape is made planar for easy manufacturing, then production is simplified, but the release tape detaches during the process due to restoring forces and inertia, causing a pop-up phenomenon
Solution Approach 1:
The release tape is divided into multiple non-connecting portions by second cutting lines that align with the first cutting lines, allowing each segment to be independently removed without generating restoring forces that would cause the pop-up phenomenon, while the connecting portions maintain structural integrity during handling
3Device complexity
If the release tape has the same area as the adhesive tape, then the structure is simple, but impurities can stick to the adhesive tape surface, affecting adhesion quality
Solution Approach 1:
The release tape is designed with a larger area than the adhesive tape body, creating an extended protective surface that prevents impurities from contacting the adhesive tape during storage and handling, while the extra area is removed after application without affecting the adhesive bond

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design ensures bubble-free and wrinkle-free adhesion, enhances cohesive force, prevents impurity sticking, and improves wear sensation by maintaining adhesion on various nail curvatures without the 'pop-up' phenomenon.
Implementation Method 1

AI summary
Provided is a one-touch artificial nail including: a thin film nail body (210) coupled to a nail and having one end coupled to be located at a free edge side of the nail, the other end coupled to be located at a cuticle side of the nail, and an adhesive surface formed at a location facing the nail; a design layer (220) formed by painting an upper portion of the nail body (210); a double-sided adhesive tape body (110) attached to a lower portion of the nail body and having a plurality of curved portions where a plurality of first cutting lines (114) having a linear shape in a vertical direction are formed, and connecting portions formed between the first cutting lines so that the plurality of curved portions are not separated; and a release tape (120) detachably coupled to a lower portion of the double-sided adhesive tape body (110), having a greater area than the double-sided adhesive tape body (110), and having a plurality of second cutting lines (124) formed at the same locations as the first cutting lines (114) to pass in the vertical direction, wherein the release tape (120) has a grip (122) connecting to and protruding from the outer circumference of the release tape (120), and the grip (122) is disposed at a location protruding from the outer circumference of the nail body (210). Since the one-touch artificial nail may be attached to the artificial nail without bubbles or winkles, it is possible to prevent the adhesive area from decreasing, thereby improving the cohesive force. Therefore, the one-touch artificial nail may be easily applied to wearers having different nail curvatures.
