Portable Nail Gel Pen with Integrated LED Curing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nail varnish lasts only 2-3 days and becomes brittle, while nail gel requires a UV light source for curing, which is often unavailable for on-the-go applications, and there is a need for a secure and inconspicuous method to attach RFID chips to the body.
Innovation Solution
A portable pen with a closable cavity for gel varnish, a brush for application, and a battery-operated LED/LEV light for curing, combined with a cavity for securely storing and attaching RFID chips to fingernails using gel varnish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If nail gel is applied outside a salon, then portability is improved, but curing reliability deteriorates due to missing UV light source
Solution Approach 1:
The patent combines the UV LED light source, gel varnish container, and application brush into a single integrated pen device. This merging allows the complete nail gel application and curing system to be portable while maintaining full functionality, resolving the contradiction between portability and curing reliability.
Solution Approach 2:
The pen device serves multiple functions: it stores gel varnish, applies it to the nail, and cures it using UV LED light. This multi-functionality eliminates the need for separate salon equipment, enabling reliable nail gel application anywhere while maintaining portability.
2Adaptability or versatility
If RFID chip is attached to fingernail, then security and convenience are improved, but attachment security deteriorates due to lack of strong bonding method
Solution Approach 1:
The patent uses gel varnish that changes from a liquid state during application to a hardened state after UV curing. This parameter change provides strong bonding to securely attach the RFID chip to the fingernail, resolving the contradiction between convenience and attachment security.
3Productivity
If gel varnish is applied in thin layers, then application speed is improved, but coverage quality deteriorates
Solution Approach 1:
The patent enables continuous application of gel varnish followed by immediate UV LED curing within the same pen device. This continuous process allows multiple thin layers to be applied and cured sequentially without interruption, maintaining both high application speed and excellent coverage quality through proper layering.
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
Enables quick and safe application and curing of nail gel anywhere, while securely and inconspicuously attaching RFID chips to the body, allowing for various applications such as financial transactions and access control.
Implementation Method 1
a battery-operated LED/LEV light for UV light for curing gel varnish applied with a brush to a finger nail
Implementation Method 2
the gel is cured with a special light source that emits UV light

AI summary
A pen has an external shape similar to that of a ballpoint pen or fountain pen. The pen includes a cavity in the tube type pen body for receiving gel varnish, and a brush for applying this to a finger nail. At the front end of the pen body, a sleeve is positioned which can be screwed on, and contained therein are LED/LEV lights, with a battery, for curing the applied gel varnish with UV light.
