Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies for achieving ultra-matt surfaces on three-dimensional elements, such as furniture and panels, face challenges in extending irradiation to non-exposed areas and edges, leading to incomplete coverage and discontinuities, and require the use of edge banding techniques, which compromise performance and productivity.
Innovation Solution
A mechanical reflection and irradiation system that extends Excimer UV radiation to shaded areas of three-dimensional elements using a combination of reflecting elements and multiple UV lamps, allowing for uniform polymerization and cross-linking of UV polymerizable coatings without edge banding, thereby achieving ultra-matt surfaces with high chemical and physical resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Excimer lamp irradiation is used on three-dimensional elements, then ultra-matt surfaces with high resistance can be obtained on exposed areas, but irradiation cannot reach shaded areas and edges, resulting in incomplete coverage
Solution Approach 1:
The patent introduces reflective elements (mirrors or reflective panels) as intermediaries to redirect UV radiation from the Excimer lamp onto shaded areas and edges of three-dimensional elements that would otherwise remain unirradiated. This mediator approach enables complete coverage while maintaining the high-quality ultra-matt surface finish through proper irradiation of all surfaces.
2Manufacturing precision
If edge banding technique is used to achieve complete coverage, then all surfaces including edges can be coated, but productivity decreases and performance is compromised
Solution Approach 1:
The patent replaces the mechanical edge banding process with an optical solution using reflective elements and multiple UV lamp positions. This substitution eliminates the need for separate edge banding operations, allowing all surfaces to be irradiated simultaneously in a single continuous process, thereby maintaining high productivity while achieving complete coverage.
3Manufacturing precision
If multiple UV lamps and reflecting elements are added to extend irradiation, then complete coverage is achieved, but device complexity increases
Solution Approach 1:
The patent divides the irradiation system into multiple independent UV lamp units positioned at different locations, each responsible for irradiating specific areas. Reflective elements are segmented to cover different zones. This segmentation allows the complex coverage requirement to be met through modular, manageable components that can be independently positioned and adjusted.
4Ease of manufacture
If standard UV lamp irradiation is used on three-dimensional elements, then processing is simple, but irradiation cannot reach shaded areas resulting in discontinuities
Solution Approach 1:
The patent adds spatial dimensionality to the irradiation system by positioning UV lamps at multiple locations and angles around the three-dimensional element. Reflective elements are arranged to redirect radiation into shaded zones. This multi-dimensional approach ensures all surfaces receive adequate irradiation while maintaining process simplicity through systematic arrangement rather than complex operations.
