Wireless Trailer Locking via RFID Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for coordinating vehicle movements at staging areas, such as delivery hubs, are inefficient due to manual processes that can take up to 15-20 minutes per vehicle, and there are issues with drivers incorrectly loading or unloading outbound loads, leading to delays and inefficiencies.
Innovation Solution
The implementation of a method using RFID technology to automate tractor/trailer exchange procedures by reading identifiers on RFID tags associated with tractors and trailers, transmitting this information to a driver's terminal, and wirelessly controlling the locking mechanism of the trailer doors, allowing for expedited and accurate dispatch procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual call box procedures are used for coordinating vehicle movements at staging areas, then drivers can receive dispatch instructions, but the process takes 15-20 minutes per vehicle and increases waiting time
Solution Approach 1:
The patent replaces manual mechanical processes (drivers physically using call boxes, dispatchers manually coordinating) with an automated electronic system using RFID tags, readers, and wireless communication to automatically identify vehicles, transmit dispatch instructions, and coordinate movements, thereby reducing the 15-20 minute manual coordination time
Solution Approach 2:
The system enables vehicles to automatically identify themselves through RFID tags when entering or leaving the staging area, eliminating the need for drivers to manually call dispatch, and allows the system to automatically track and coordinate vehicle movements without continuous human intervention
2Reliability
If drivers manually identify outbound loads using vehicle identification numbers, then they can locate trailers, but errors occur when drivers pull out with wrong loads
Solution Approach 1:
The patent replaces manual visual identification of vehicle identification numbers with an automated RFID-based electronic identification system that automatically reads tags on vehicles and trailers, accurately matches them through the information management system, and transmits confirmation to driver terminals, eliminating human error in load identification
Solution Approach 2:
The system provides feedback to drivers through terminal devices, confirming which outbound load they are assigned to and verifying proper matching, allowing drivers to confirm correct load identification before departure and reducing errors of pulling out with wrong loads
3Reliability
If door seals are manually cut and placed on trailers, then security is maintained, but the process takes 7-15 minutes per trailer
Solution Approach 1:
The patent replaces manual mechanical processes of cutting and placing physical door seals with an automated electronic locking system that uses wireless communication to remotely lock and unlock trailer doors, maintaining security while eliminating the 7-15 minute manual seal application process
Solution Approach 2:
The electronic locking system allows trailers to be automatically locked or unlocked through wireless signals transmitted to the locking mechanism, eliminating the need for manual intervention to apply physical seals while maintaining the security function
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution significantly reduces the time required for vehicle dispatch and loading/unloading processes, minimizing errors and enhancing operational efficiency by automating the identification and locking/unlocking of trailers, thereby streamlining the flow of vehicles through staging areas.
Implementation Method 1
reading a first identifier stored on a first radio-frequency identification (RFID) tag that is physically associated with a tractor
Implementation Method 2
wirelessly transmitting information along a third communications link from the driver's terminal to a locking device

AI summary
A method and system for providing improved handling of tractors and trailers (or any powered vehicle and storage devices towed thereby) with a staging area. One invention relates to the provision of automatic locking or unlocking of a trailer door when the trailer leaves or enters the hub, respectively. A RFID signal strength evaluation scheme is also provided, which monitors successful RFID-to-antennae communications under various weather conditions, in order to determine an optimum read process.Under another embodiment, Geofencing and/or Wi-Fi can be used to trigger various events.
