Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UV curing technologies for skin-feel matte effects suffer from low efficiency, poor reflection, and high production costs due to inadequate lamp arrangement and wavelength usage, leading to suboptimal skin-feel and matte effects.
Innovation Solution
A process utilizing a light source with a wavelength of 250-260 nm for pre-curing, followed by a conventional UV curing machine, and optionally a pre-curing device like an LED lamp, to achieve a non-smooth, wrinkled surface with a diffusely reflective effect, combined with a post-curing device for complete curing, optimizing the skin-feel and matte finish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If UV excimer lamps with wavelength 172-185 nm are used to achieve skin-feel effect, then the skin-feel effect is achieved, but the production cost increases and the process structure becomes complex
Solution Approach 1:
The patent changes the wavelength parameter from 172-185 nm (excimer lamps) to 250-260 nm (UV lamps), achieving the skin-feel effect through parameter modification rather than requiring specialized equipment. This resolves the contradiction by maintaining the desired effect while simplifying the process structure and reducing costs.
2Productivity
If all UV excimer lamp components are arranged above the conveying assembly, then the device structure is simple, but the lamps cannot irradiate the lower surface of plates resulting in low working efficiency
Solution Approach 1:
The patent transitions from a single-dimensional (above-only) lamp arrangement to a multi-dimensional arrangement by placing lamps both above and below the conveying assembly. This enables irradiation of all plate surfaces simultaneously, improving working efficiency without excessive structural complexity.
3Manufacturing precision
If arc-shaped reflective structure with fewer reflective surfaces is used, then the device structure is simplified, but the reflection effect is poor and skin-feel effect is insufficient
Solution Approach 1:
The patent divides the reflective structure into multiple planar reflective surfaces instead of using a single arc-shaped structure. This segmentation increases the total reflection area and improves the reflection effect, achieving better skin-feel effect while maintaining reasonable structural complexity through modular planar elements.
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 process ensures uniform and efficient curing of UV skin-feel matte paint across all surfaces, achieving a soft, matte finish with a glossiness of 0.5-5.0 degrees, enhancing the skin-feel and matte effect while reducing production costs and heat accumulation.
Implementation Method 1
a light source with a wavelength of 250-260 nm is used to irradiate a workpiece that is roller-coated or spray-coated with a UV skin-feel matte paint, such that a surface layer of a UV skin-feel matte paint film on the workpiece contracts and forms a non-smooth and wrinkled surface
Implementation Method 2
a conventional UV curing machine is also used to perform final overall irradiation on a workpiece that is roller-coated or spray-coated with a UV skin-feel matte paint, such that a surface layer of a UV skin-feel matte paint film on the workpiece is completely cured

AI summary
The present invention relates to a skin-feel matte preparation process. A pre-curing lamp device is used to preliminarily cure the paint surface of a workpiece coated with an ultraviolet (UV) skin-feel matte paint, and a final curing lamp device is used to completely and ultimately cure the paint surface of the workpiece coated with the UV skin-feel matte paint. The final curing lamp device includes a skin-feel matte curing lamp with a wavelength of 253-257 nm. The skin-feel matte curing lamp irradiates the UV skin-feel matte paint on the workpiece, causing the UV skin-feel matte paint to contract and form a non-smooth paint surface, thereby achieving a matte effect on the workpiece paint surface. This process uses the skin-feel matte curing lamp with a wavelength of 253-257 nm to irradiate the UV skin-feel matte paint on the workpiece surface, effectively causing the UV skin-feel matte paint to contract on the workpiece surface and form a non-smooth state, imparting a soft, baby-skin-like tactile quality, while also achieving an extremely matte effect of 0.5-5.0 degrees on the workpiece paint surface, with pronounced skin-feel and matte effects.
