Cargo Container Security System Using Weight Sensors and RFID
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cargo theft and damage are significant issues in the transportation industry due to inadequate security measures, inaccurate tracking, and lack of integrated security systems that can detect unauthorized activities and prevent property damage at large facilities.
Innovation Solution
A security, tracking, and damage control system using a combination of weight sensors, RFID tag readers, laser bandwidth transceivers, and LAN wireless communication to verify and log vehicle and container information, guide drivers for safe parking, and alert authorities to unauthorized activities, while automatically assigning yard tugs and recording vehicle movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security measures (cameras, seals, locks) are used, then basic security coverage is provided, but they are easily compromised or rendered inoperable
Solution Approach 1:
The patent replaces mechanical security measures (cameras, seals, locks) with an integrated electronic system comprising weight sensors, RFID tag readers, laser bandwidth transceivers, and communication terminals that detect and respond to unauthorized activities electronically, making the system harder to compromise with traditional tools
Solution Approach 2:
The patent introduces intermediary devices such as RFID tags and weight sensors that act as mediators between the cargo container and security authorities, providing continuous verification and alerting mechanisms that bridge the gap between physical security needs and remote monitoring capabilities
2Measurement precision
If manual tracking and security monitoring are used, then system complexity is reduced, but accuracy of tracking and response time to unauthorized activities deteriorate
Solution Approach 1:
The patent creates a multi-functional integrated system where a single infrastructure supports weight sensing, RFID communication, laser guidance, and security monitoring simultaneously, reducing the need for separate manual systems while achieving high tracking accuracy and automated response capabilities
Solution Approach 2:
The system enables self-service monitoring and tracking where the cargo container itself (through integrated sensors and communicators) automatically reports its status, location, and security conditions without requiring manual intervention, thereby improving accuracy while managing complexity through automation
3Loss of information
If satellite tracking is used, then remote tracking capability is provided, but it is susceptible to interference and does not address facility-level security problems
Solution Approach 1:
The patent segments the tracking system into multiple layers: satellite tracking for remote location and facility-level RFID/weight sensor systems for detailed security monitoring. This segmentation allows each system to operate independently and reliably within its optimal range, with the facility-level system providing backup and enhanced detail when satellite signals are unavailable
4Object-affected harmful factors
If no integrated security system is used, then device complexity is reduced, but unauthorized activities and property damage increase
Solution Approach 1:
The patent merges multiple security functions (weight sensing, RFID identification, laser guidance, communication) into a single integrated system that operates cohesively. This consolidation improves detection capabilities and response effectiveness while managing complexity through unified architecture and centralized control protocols
Data Source
AI summary
A security, tracking and damage control system for use primarily within the commercial transportation industry. The system consists of a line containing a weight sensor within a security pad, and deploys LAN wireless communication between facility traffic control and tractors (trucks), yard tugs and receptor/detector transceivers located in line. A communications terminal, located in the truck, is preprogrammed at trucking company to include driver name, ID, truck number, and trucking company. Shipper will program trailer number and commodity, and any other relevant information pertaining to the shipment. This information will be relayed by shipper to consignee and will be verified automatically along with driver ID and truck number, when truck arrives at facility.
