Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack an efficient method to validate bar codes by distinguishing between the bar code and background data in images, leading to potential misidentification and invalidation of bar codes, especially in scenarios where bar codes are stolen or incorrectly placed on different items.
Innovation Solution
A wireless communication device and processing system that optically receive and process image data to separate bar code and background portions, comparing decoded data against validation files to determine validity, with the ability to communicate wirelessly for remote processing and validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If bar code readers optically read bar codes to generate image data, then bar code decoding is achieved, but the system cannot distinguish between bar code data and background data leading to potential misidentification
Solution Approach 1:
The system segments the optically received data into distinct bar code portions and background portions using image processing techniques. This segmentation allows the system to separately analyze and validate bar code data against background information, preventing misidentification and improving validation reliability.
Solution Approach 2:
The system introduces an intermediary validation process that compares decoded bar code data with background information. This intermediary step acts as a mediator to verify authenticity, ensuring that bar codes are not misidentified or incorrectly validated.
2Ease of operation
If bar codes are placed on items without validation, then item identification is simplified, but stolen or incorrectly placed bar codes cannot be detected
Solution Approach 1:
The system implements a feedback mechanism where the optically received data is validated by comparing bar code portions with background portions. This feedback loop provides confirmation of bar code authenticity, allowing the system to detect stolen or incorrectly placed bar codes while maintaining ease of operation through automated validation.
3Productivity
If remote processing systems are used to validate bar codes, then processing capability is increased, but system complexity and communication requirements increase
Solution Approach 1:
The validation system is designed with multi-functionality to handle various validation scenarios through a unified architecture. The system can process different types of bar codes and background information using the same core validation logic, reducing overall system complexity while maintaining high processing capability.

AI summary
A wireless communication device optically receives and processes a bar code and a background item to the barcode to generate image data. A processing system processes the image data to identify a bar code portion of the image data and to identify a background portion of the image data. The processing system processes the barcode portion of the image data to generate decoded data. The processing system processes the background portion of the image data to generate background data. The processing system processes the decoded data and the background data to determine if the bar code is valid. The wireless communication device generates a bar code valid signal if the bar code is valid and generates a bar code invalid signal if the bar code is invalid.
