Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS satellite tracking systems and electronic monitoring technology are used to track shipment locations in real-time, then the accuracy and timeliness of location information is improved, but the system cost becomes prohibitively expensive
Solution Approach 1:
The patent uses inexpensive RFID tags instead of expensive GPS satellite tracking systems. The RFID tags are low-cost electronic identifiers that can be attached to shipments, providing location tracking capability without the high expenses associated with GPS technology. This resolves the contradiction by achieving adequate tracking accuracy through a much more cost-effective means.
Solution Approach 2:
The patent replaces the mechanical/electronic GPS tracking system with an RFID-based identification system. Instead of using satellite-based electronic monitoring, the system uses radio frequency identification tags that can be read by fixed or mobile readers, substituting a simpler, less expensive technological approach for the complex GPS infrastructure.
2Loss of information
If code scanning systems are used to maintain shipment records, then the ability to track shipments is improved, but the requirement for affirmative manual scanning steps increases operational complexity
Solution Approach 1:
The RFID tags automatically provide identification information when queried by readers, eliminating the need for manual scanning operations. The system performs the tracking function itself through automated reader-tag communication, rather than requiring human operators to manually scan codes at each waypoint. This resolves the contradiction by maintaining accurate records while dramatically simplifying operations.
Solution Approach 2:
The RFID tags are preattached to shipments before they enter the tracking system. This preliminary action ensures that the tracking identifier is already in place and ready for automatic detection, eliminating the need for manual code scanning steps during the shipping process. The information is prepared in advance for automated collection.
3Device complexity
If manual paperwork methods are used for shipment record keeping, then the system cost is reduced, but the accuracy and completeness of delivery records deteriorates
Solution Approach 1:
The patent replaces manual paperwork systems with an automated RFID tracking system. Instead of using paper-based record keeping that is prone to errors, loss, and incomplete information, the system uses electronic RFID tags and readers that automatically capture and store shipment data. This resolves the contradiction by achieving high record accuracy through a moderately priced electronic system rather than expensive comprehensive automation.
Solution Approach 2:
The RFID tag serves as an intermediary carrier of shipment information. Rather than relying on manual paper documentation or expensive comprehensive electronic systems, the RFID tag acts as a simple, reliable intermediary that stores and transmits essential shipment data automatically. This intermediate solution provides improved accuracy at a reasonable cost.

AI summary
A comprehensive method and system is provided for managing bulk and non-bulk material and assets using radio frequency and other asset identification devices, distributed mobile computing systems, centralized data storage environments, and client-server based computing. In particular, a process has been designed and to manage shipment items from businesses and third parties to customer designated locations. Components of this system include electronic asset identification devices, a central data repository, a mobile computing environment and associated software applications supporting a client-server system or n-tiered computer system. The mobile computing environment includes software which enables users to physically locate assets, view asset information, and modify such information to reflect current asset status. This information may then be exchanged and synchronized across the n-tiered computer system. Additionally, various personnel associated with the shipping arrangement may have access to the available information over a computer network such as the Internet. In this manner, such personnel can easily determine the status of various shipments and also promptly act on information collected during any status updates, thereby expediting the resolution of any potential exceptions which may arise. The electronic asset identification devices may be further configured to include various types of sensors. The devices may then operate to process and store sensor output information for subsequent relay to users via the mobile computing environment or other means.
