System for manufacturing a substrate with a decorative design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for applying decorative designs on substrates require frequent changes of foil feed spools to accommodate different designs, limiting versatility and flexibility in manufacturing substrates with repetitive or varied designs.
Innovation Solution
A system incorporating digital printing means to print decorative designs on foils before coating, allowing for continuous or discontinuous foil feeding, and adaptive application of adhesive glue based on substrate and foil features, enabling versatile and flexible manufacturing of substrates with diverse decorative designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If foil feed spools are changed to accommodate different decorative designs, then design versatility is improved, but manufacturing efficiency and productivity deteriorate due to frequent changes
Solution Approach 1:
The system employs a single foil feed spool that can continuously supply foil for multiple different decorative designs through digital printing, making the spool universal for various designs rather than requiring dedicated spools for each design
Solution Approach 2:
The decorative design on the foil is changed by modifying the digital printing parameters and patterns rather than physically changing the foil spool, allowing continuous production with varying designs
2Adaptability or versatility
If digital printing means are added to print decorative designs on foil, then design versatility and flexibility are improved, but device complexity increases
Solution Approach 1:
The patent replaces mechanical design change mechanisms (physical spool changes, manual foil handling) with a digital printing system that uses digital commands to change designs, reducing mechanical complexity
Solution Approach 2:
The system uses digital copies and patterns stored in memory to generate decorative designs through printing, eliminating the need for physical design storage media and manual design transfer processes
3Reliability
If adhesive glue application is adapted based on substrate and foil features, then coating quality and reliability are improved, but process complexity increases
Solution Approach 1:
The system incorporates sensors that detect substrate and foil features and provide feedback to the adhesive application mechanism, enabling automatic adjustment of glue application parameters based on real-time measurements
Solution Approach 2:
The adhesive application system automatically adjusts its parameters based on sensor feedback about the substrate and foil characteristics, making the process self-regulating without manual intervention

AI summary
A system for manufacturing a substrate with a decorative design, such as an image and/or a relief, which has feed means for feeding a foil, digital printing means for printing the decorative design on the foil and coating means for coating the substrate with the foil. The system is configured for printing the foil with the digital printing device after supplying the foil with the feed means and before coating the substrate with the coating means.
