Solution Overview
Problem
Existing coating systems struggle to provide optimal treatment of the lateral, head, and tail surfaces of manufactured articles, leading to non-uniform treatments and increased costs due to the need for additional processing steps.
Innovation Solution
An apparatus with a conveying system and optic groups featuring reflecting members that distribute radiation uniformly across the upper, lateral, head, and tail surfaces of manufactured articles, combined with a nitrogen injection system to maintain an inert atmosphere, ensuring comprehensive and efficient treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If reflecting systems are used to treat lateral surfaces, then treatment coverage is improved, but treatment uniformity deteriorates
Solution Approach 1:
The radiation source is moved from a lateral position to a superior (top) position relative to the panel, treating lateral surfaces by irradiating from above at an angle. This dimensional change allows simultaneous treatment of upper and lateral surfaces while maintaining uniform radiation distribution through the angled incidence geometry
2Manufacturing precision
If multiple treatment passes are implemented, then treatment completeness is improved, but process time and cost increase
Solution Approach 1:
The treatment of upper surfaces and lateral surfaces is merged into a single irradiation pass by positioning the radiation source superior to the panel. The angled radiation from the top position simultaneously treats both surface types in one operation, eliminating the need for separate treatment passes
Solution Approach 2:
A single radiation source configuration serves multiple functions: treating the upper surface directly and treating lateral surfaces through angled irradiation. This multi-functional approach consolidates what would traditionally require separate treatment systems or passes
3Reliability
If nitrogen pumping systems are used, then inert atmosphere quality is improved, but nitrogen consumption increases
Solution Approach 1:
Nitrogen is injected locally at specific positions (superior and lateral to the panel) rather than pumping the entire chamber. This localized injection provides inert atmosphere protection exactly where the radiation sources operate, reducing overall nitrogen consumption while maintaining atmosphere quality in the treatment zone
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 apparatus ensures uniform treatment of all surfaces, reduces nitrogen consumption, and enhances the quality of the inert atmosphere, thereby improving the coating process efficiency and reducing costs.
Implementation Method 1
at least one radiation source for the treatment of said photosensitive paint
Implementation Method 2
said at least one optic group comprises a reflecting member arranged in said housing cavity, in correspondence of said radiation source, so as to spread its emitted radiation
Implementation Method 3
these manufactured articles are subjected to illumination by means of an excimer lamp, with ultraviolet radiation usually having a wavelength of 172 nm
Implementation Method 4
Treatment by means of excimer lamps has to take place in an inert atmosphere. Therefore, the plants according to the prior art provide nitrogen pumping systems, to minimize the oxygen within the volume
