Nail Lamp Angled Surface Light Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current nail lamps fail to provide uniform curing of artificial nails, particularly affecting the thumb nails, leading to non-uniform curing results.
Innovation Solution
The design incorporates an angled surface at the perimeter of the nail treatment space to reflect light towards the center, increasing light exposure on the thumb nail and using reflectors integrated with the light sources to enhance light distribution across all nails, ensuring uniform curing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If light sources are positioned directly above the nail treatment space, then the structure is simple and easy to manufacture, but the light distribution is non-uniform particularly affecting thumb nails
Solution Approach 1:
The patent applies local quality by positioning reflectors specifically at peripheral locations around the nail treatment space, creating localized light reflection zones that target areas needing additional illumination (particularly thumb nails), while the central area receives direct light from the light sources above.
Solution Approach 2:
The patent introduces reflectors as intermediary elements between the light sources and the nails. These reflectors mediate the light distribution by redirecting light paths to reach peripheral and thumb nail areas that would otherwise be under-illuminated, achieving more uniform curing without fundamentally changing the direct overhead lighting arrangement.
2Productivity
If light intensity is increased to improve curing speed, then productivity increases, but energy consumption increases
Solution Approach 1:
The patent converts the potentially wasted light energy that would otherwise be lost in peripheral areas into useful curing energy by using reflectors to redirect this light toward the nails, particularly the thumb nails that are hardest to reach. This improves curing efficiency without requiring additional energy input.
Solution Approach 2:
The patent changes the spatial distribution parameters of light intensity by introducing reflectors that redirect light to specific zones, thereby achieving more uniform light distribution across all nails without increasing the overall energy consumption or light source intensity.
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
The solution achieves improved uniformity in curing artificial nails by increasing light intensity and distribution, particularly benefiting the thumb nail, resulting in enhanced durability and wear properties.
Implementation Method 1
an angled surface e.g. wall which reflects light from the perimeter of the nail treatment space, towards the center of the nail treatment space
Implementation Method 2
use of reflectors that are associated with each light source and integrated with the overall lamp structure to increase the amount of light impacting all nails in a given lamp
Implementation Method 3
The photo initiators react with light to form radical photo initiators, which in turn, react with the ingredients listed above to form a nail coating

AI summary
A nail lamp is configured to cure light-curable nail product on a user's nails. The lamp includes an array of discrete light sources. A nail treatment space is disposed beneath the array and is sized to accommodate therein at least one nail of a user so as to expose the user's at least one nail to light from the array. The nail lamp includes a number of features to improve the uniformity of exposure of the at least one user nail to light relative to existing lamps. These features include one or more angled surfaces and light reflectors.
