Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing management systems using information codes face challenges in reliably determining the authenticity of products, as reproduced information codes can be difficult to distinguish from original ones, leading to potential counterfeit issues and compromised reliability in product management.
Innovation Solution
A management system that includes an information terminal for reading and transmitting code identification information, along with position and time data, to a server for authenticity determination, which considers the reading position and time to verify the legitimacy of the information code, thereby improving the reliability of product authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If information code is used for product management, then ease of operation is improved, but reliability deteriorates due to difficulty in distinguishing reproduced codes from original ones
Solution Approach 1:
The patent adds spatial and temporal dimensions to the information code verification process. Instead of only verifying the code content, the system now verifies the reading position (spatial dimension) and reading time (temporal dimension) against registered data. This multi-dimensional approach enables distinction between genuine and reproduced codes while maintaining ease of operation through automated verification.
2Device complexity
If simple information code reading is implemented, then device complexity is reduced, but measurement precision deteriorates in determining code authenticity
Solution Approach 1:
The verification process is segmented into distinct components: code content verification, reading position verification, and reading time verification. Each component is handled separately by different system modules (reading portion, position information acquisition portion, determination portion). This segmentation allows the system to maintain simplicity while achieving high precision through cumulative verification of multiple parameters.
3Adaptability or versatility
If information code reproduction is allowed, then adaptability is improved, but reliability deteriorates due to counterfeit circulation
Solution Approach 1:
The system implements feedback mechanisms where the determination portion continuously monitors verification results and provides feedback to the notification portion. When a reproduced code is detected through position-time verification, the system provides immediate feedback by notifying the user of potential forgery. This feedback loop maintains system adaptability while ensuring reliability through active counterfeit detection.

AI summary
A management system includes: an information terminal that reads an information code attached to a management target, the information code storing code identification information that specifies the management target; and a server communicable with the information terminal. The information terminal includes: a reading portion that optically reads display information including the information code; a position information acquisition portion that acquires position information of the information terminal; a terminal-side transmission portion that transmits the position information as reading position information to the server; and a notification portion that notifies predetermined information. The server includes: a storage portion that stores management information; a determination portion that determines whether the code identification information corresponds to information of the information code attached to the management target; and a server-side transmission portion that transmits a determination result to the information terminal. The notification portion notifies information with respect to the determination result.
