Panel Decoration Printing Using Fixed Carrier Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method of decorating panels is time-consuming due to the need for recognizing and aligning a decorative basic pattern with a curable substance, requiring intermediate positioning actions and separate coordinate calculations for each printing step, which slows down the manufacturing process.
Innovation Solution
The method involves performing both printing steps according to a predetermined positional relationship, with the panel held at a fixed position relative to the carrier, allowing the use of a single reference set of coordinates for both steps, eliminating the need for intermediate positioning and recognition processes, and enabling continuous, high-accuracy printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a camera recognition process is performed before the digital printing station to align the curable substance pattern with the decorative basic pattern, then the alignment accuracy is improved, but the manufacturing time increases
Solution Approach 1:
The panel is positioned and fixed on the carrier before the first printing step, establishing a predetermined positional relationship that eliminates the need for subsequent recognition and realignment operations. This preliminary positioning action enables both printing steps to use identical coordinates, resolving the contradiction by maintaining high alignment accuracy while eliminating time-consuming intermediate processes.
Solution Approach 2:
The patent removes the camera recognition process and intermediate positioning actions from the manufacturing workflow. By establishing the positional relationship beforehand and maintaining the panel at a fixed position, the system extracts unnecessary time-consuming steps while preserving alignment accuracy through the predetermined coordinate system.
2Manufacturing precision
If intermediate positioning actions are performed to align the panel with the second printing module, then the printing precision is improved, but the manufacturing complexity increases
Solution Approach 1:
A single coordinate system is used for both the first and second printing steps, making the positioning system universal across different printing operations. The panel's fixed position on the carrier serves multiple functions: it enables both printing steps without relocation and ensures precise pattern alignment, thereby reducing manufacturing complexity while maintaining high printing precision.
Solution Approach 2:
The patent merges the positioning operations for both printing steps into a single preliminary action. By establishing the panel's position before the first printing step and maintaining it throughout, the system combines what would otherwise be separate positioning operations, reducing complexity while ensuring precise printing alignment.
3Adaptability or versatility
If separate coordinate calculations are performed for each printing step, then the flexibility in printing different patterns is improved, but the processing time increases
Solution Approach 1:
A single reference set of coordinates is established beforehand for the carrier coordinate system, which can be used for both printing steps without recalculation. This preliminary coordinate establishment maintains pattern flexibility because the same coordinate system accommodates both identical and deliberately deviating patterns, while eliminating time-consuming separate coordinate calculations.
Solution Approach 2:
The use of identical coordinates for both printing steps enables a continuous printing process without interruption for coordinate recalculation or panel repositioning. The continuous use of the same reference system maintains flexibility in printing different patterns while eliminating time losses associated with separate coordinate processing.

AI summary
A method of decorating a panel includes the steps of supplying a panel to a carrier, performing at least a first printing step by means of a first printing module and performing a second printing step by means of a second printing module. The first and second printing steps are performed according to a predetermined positional relationship to form the decorated panel. Between the first and second printing steps, the panel is held at a substantially fixed position with respect to the carrier.
