Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In materials handling facilities, existing barcode labeling systems lack efficient verification of barcode accuracy and machine-readability before application to packages, leading to potential errors in package routing and delivery, especially in high-speed and high-volume processes.
Innovation Solution
An integrated barcode printing and scanning device that includes a printer, a label applicator, and a scanner, where the scanner verifies the barcode accuracy and readability in real-time before applying the label, allowing for immediate rejection or reprinting of defective labels, and is positioned between the printer and applicator to protect from environmental factors and ensure accurate scanning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing barcode labeling systems are used without integrated verification, then the labeling process is simpler and faster, but barcode accuracy and machine-readability cannot be verified before application, leading to potential routing errors
Solution Approach 1:
The patent combines the barcode scanner, printer, and label applicator into a single integrated labeling system. The scanner is positioned within the labeling device to verify barcodes in real-time during the labeling process, merging verification functionality with the existing labeling operations. This integration allows barcode accuracy verification without requiring separate external verification equipment, thus improving reliability while managing system complexity.
2Loss of time
If barcode verification is performed after label application, then the system is simpler, but defective barcodes cannot be detected before application, causing rework and downtime
Solution Approach 1:
The patent implements preliminary barcode verification by positioning the scanner to read and verify barcodes before the label is applied to the package. The system checks barcode accuracy and machine-readability in real-time during the labeling process, allowing defective labels to be rejected before application. This preliminary verification prevents rework and downtime that would occur if verification were performed after application, while maintaining efficient labeling operations.
3Adaptability or versatility
If external scanners are used for barcode verification, then the scanning function is separate, but the system requires additional equipment and increases overall system complexity
Solution Approach 1:
The patent integrates the barcode scanner directly into the labeling device, combining the scanning verification capability with the existing printer and applicator. This integration eliminates the need for separate external scanners and reduces the number of discrete devices required. The scanner is positioned within the labeling system to perform verification during the normal labeling process, providing adaptability and versatility while reducing overall system complexity.

AI summary
A labeling device includes a printer configured to print labels each having a barcode on a print side of the label opposite an adhesive side of the label. The printer is also configured to direct each printed label in a direction of travel. The device includes a label applicator located downstream of the printer with respect to the direction of travel. The device also includes a barcode scanner that is located downstream of the printer with respect to the direction of travel and is configured to scan the barcode of each label before the label applicator presses the label against the package.
