Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current barcode scanner systems are cumbersome for user authentication, lack separate authentication mechanisms, and are inefficient in recognizing both one-dimensional and two-dimensional codes, making it difficult to track who scans specific products, especially in industrial settings.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate authentication system is added to the barcode scanner, then user identification capability is improved, but device complexity increases
Solution Approach 1:
The patent combines the fingerprint recognition module directly into the barcode scanner device, merging authentication functionality with scanning functionality. This integration allows user identification and barcode scanning to occur within a single unified system, improving reliability by ensuring only authorized users can scan while managing complexity through consolidation rather than addition of separate standalone systems.
Solution Approach 2:
The barcode scanner is designed to perform multiple functions: it acts as both a barcode scanning device and a biometric authentication device. The fingerprint recognition module and scan module share the same hardware platform and control system, enabling the device to universally handle both identification and scanning tasks, thereby improving user identification capability without proportionally increasing overall system complexity.
2Adaptability or versatility
If both one-dimensional and two-dimensional scanning modules are integrated, then code recognition versatility is improved, but device complexity increases
Solution Approach 1:
The patent integrates both a scan module for one-dimensional barcodes and a QR code scan module for two-dimensional codes within a single device. This multi-functional design allows the barcode scanner to universally recognize various code types without requiring separate dedicated devices, thereby improving adaptability while managing complexity through shared hardware resources and unified control architecture.
Solution Approach 2:
Multiple scanning functionalities are merged into a single integrated device. The scan module and QR code scan module are combined within the same hardware platform, sharing common components such as the image sensor, processing unit, and communication interface. This consolidation improves code recognition versatility while avoiding the complexity of maintaining entirely separate scanning systems.
3Reliability
If fingerprint authentication is implemented, then security is improved, but operation time increases
Solution Approach 1:
The system performs preliminary actions by having users register their fingerprint information in advance before actual scanning operations. During authentication, the system quickly compares the captured fingerprint against pre-stored template data. This preliminary preparation of authentication data significantly reduces the time required during actual use, as the complex biometric processing has already been partially completed during registration, thereby improving security while minimizing authentication time loss.
4Adaptability or versatility
If a coupling structure is designed for module switching, then adaptability is improved, but manufacturing complexity increases
Solution Approach 1:
The patent divides the barcode scanner into distinct functional modules (scan module, QR code scan module, fingerprint recognition module) that can be independently manufactured and then assembled through a coupling structure. This segmentation allows each module to be optimized and produced separately using specialized manufacturing processes, then combined through standardized interfaces, thereby improving adaptability for different configurations while managing manufacturing complexity through modular assembly rather than monolithic construction.

AI summary
A barcode scanner system includes a scan unit which includes, on one surface thereof, a scan module for scanning a barcode and has, on the other surface thereof, a structure for coupling to a body unit; and the body unit which has one surface having a shape corresponding to the coupling structure of the scan unit, and includes a display module, a communication module, an operation module, and a fingerprint recognition module. The body unit recognizes fingerprint information of the user through the fingerprint recognition module, and transmits the fingerprint information to a server to perform authentication. When a user input to the operation module occurs after authentication completion information is received from the server, a barcode scan is performed, and the scanned barcode information is transmitted to the server. Barcode information and user information identified through recognition of the fingerprint information are matched and stored in the server.
