Corrugated Cardboard Plant Individual Code Reading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current corrugated cardboard production methods are inefficient and lack the capability to produce individualized corrugated cardboard sheets with embedded information carriers that can be easily read and processed.
Innovation Solution
A corrugated cardboard plant with a corrugated cardboard production device, connection device, and cutting device, equipped with an individual code reading device to create and read two-dimensional corrugated cardboard sheet individual codes on the webs, allowing for the production of three-ply corrugated cardboard sheets with embedded information that can be machine-readable and dynamically modified.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional corrugated cardboard production methods are used, then large quantities of corrugated cardboard sheets can be produced, but the production lacks individualization capability and efficiency
Solution Approach 1:
The patent applies preliminary action by printing individual codes on the webs before the corrugated cardboard sheets are cut and separated. The coding device prints unique identification codes, batch information, or individual sheet information on the continuous web at an early stage in the production process, enabling subsequent individualized processing and tracking without requiring post-production customization
Solution Approach 2:
The patent uses copying by creating digital representations of information carriers (codes, barcodes, data matrices) that are printed onto the physical corrugated cardboard sheets. These copied information carriers serve as machine-readable substitutes for physical identification, enabling efficient digital tracking and processing of individual sheets throughout the production and supply chain
2Loss of information
If individual codes are printed on corrugated cardboard sheets, then tracking and individual processing are enabled, but additional devices and process steps are required
Solution Approach 1:
The patent applies universality by designing a coding device that can print multiple types of information carriers (barcodes, data matrices, alphanumeric codes) and multiple types of information (individual sheet identification, batch information, routing instructions) using a single integrated system. The control device coordinates this universal coding system to work with the existing corrugated cardboard production line, eliminating the need for separate specialized devices for each coding requirement
Solution Approach 2:
The patent merges the coding function with the existing corrugated cardboard production process by integrating the coding device into the web handling line. The individual codes are printed on the continuous web during or immediately after the lamination process, combining the coding operation with the existing web transport and processing infrastructure rather than requiring separate post-production coding stations
3Strength
If three-ply corrugated cardboard webs are produced with lamination web, then structural integrity is improved, but the addition of information carriers increases production complexity
Solution Approach 1:
The patent applies segmentation by separating the information carrier layer from the structural corrugated cardboard layers. The lamination web serving as the substrate for individual codes is processed and coded separately, then integrated with the corrugated web in the standard lamination process. This segmentation allows the information carriers to be added without interfering with the structural integrity of the three-ply construction
Solution Approach 2:
The patent uses preliminary action by preparing and coding the lamination web with individual codes before it is laminated to the corrugated web. The coding device prints information carriers on the lamination web while it is still in continuous form, allowing the codes to be applied to the final product structure without requiring additional post-lamination processing steps
