Item-Level Freight Tracking via Barcode Scanning and Web Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing supply chain management systems are inefficient and inaccurate as they track freight only at the shipment level, require insecure firewall modifications for data transmission, and lack a secure method for multiple users to access data, leading to potential losses and security breaches.
Innovation Solution
A system that uses bar code scanning to track freight at the carton or item level, a web service to directly insert data into a centralized SQL database, and internet-based reports accessible by multiple users via common web browsing tools, ensuring accurate, efficient, and secure data management across the supply chain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If bar code scanning is used to track freight at the carton or item level, then measurement precision and reliability are improved, but device complexity increases
Solution Approach 1:
The patent replaces manual counting and paper-based tracking systems with automated bar code scanning technology. Handheld scanners and fixed scanners automatically capture item identification information, eliminating manual data collection and significantly improving tracking precision while reducing human error.
Solution Approach 2:
The patent introduces a centralized database as an intermediary to manage the complexity of item-level tracking. The database receives data from multiple scanners, stores item information centrally, and provides it to authorized users, thereby simplifying the overall system architecture and making item-level tracking manageable.
2Reliability
If a centralized database with web service is implemented, then data reliability and security are improved, but device complexity increases
Solution Approach 1:
The patent merges data collection, storage, and distribution functions into a centralized database system. All scanners connect to the same database through standardized web services, consolidating data management and improving reliability through centralized control and consistent data access.
Solution Approach 2:
The patent implements a universal web service interface that allows different types of scanners (handheld, fixed, mobile) to access the database using the same protocol. This multi-functional approach simplifies system complexity by providing a single standardized method for data access across diverse devices.
3Ease of operation
If multiple users can access data via web browsing tools, then ease of operation is improved, but security risks increase
Solution Approach 1:
The patent introduces a web service layer as an intermediary between users and the database. This layer handles authentication, authorization, and data validation, allowing multiple users to access data through standard web browsers while maintaining security through controlled access mechanisms.
Solution Approach 2:
The system implements authentication and authorization feedback mechanisms that verify user credentials and permissions before granting database access. This ensures that only authorized users can access appropriate data, maintaining security while enabling broad accessibility through web browsing tools.
4Productivity
If electronic files are transmitted using VAN or FTP processes, then productivity is improved, but security risks and device complexity increase
Solution Approach 1:
The patent replaces traditional VAN and FTP file transmission mechanisms with direct database queries through web services. Instead of transmitting electronic files that require firewall modifications, the system allows authorized users to query and retrieve data directly from the centralized database, improving productivity while eliminating security vulnerabilities associated with file transmission.
Solution Approach 2:
The web service acts as an intermediary that replaces the file transmission layer. It provides a secure, standardized interface for data access that eliminates the need for firewall modifications and direct file transfers, thereby maintaining productivity while reducing security risks.
Data Source
AI summary
An electronic system for managing items in a supply chain. The system generally includes item information capturing means, such as a handheld device, adapted for capturing identification information associated with an item identified for supply chain management; mode specifying means adapted for receiving user input representative of a selection of at least one of a plurality of capturing modes, wherein each capturing mode is adapted for creating associated information by associating the captured item information with supply chain information; and transferring means adapted for transferring the associated information to an electronic storage device.
