Solution Overview
Problem
Current systems lack an efficient and reliable method for automatic, seamless communication between truck and trailer tracking devices and a central monitoring station, leading to a significant record-keeping burden for logistics and shipping companies.
Innovation Solution
A system that includes trailer and truck tracking devices equipped with GPS modules, short-range, and long-range communication interfaces, which communicate via wireless networks to a central server, transmitting status and location information when coupled, decoupled, or experiencing specific events, such as motion or battery low conditions, to facilitate real-time monitoring and reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual tracking and record-keeping of cargo trailers is used, then no complex communication system is needed, but the record-keeping burden and time consumption increase significantly
Solution Approach 1:
The tracking devices on trailers and trucks automatically perform tracking, data collection, and communication functions without requiring manual intervention. The system self-manages the recording and transmission of location and status information, eliminating the manual record-keeping burden while maintaining reasonable system complexity through automated operations.
Solution Approach 2:
The communication system is designed to handle multiple functions including location tracking, status monitoring, data transmission, and event notification through a unified platform. This multi-functional approach improves tracking efficiency by consolidating various operations into a single system rather than requiring separate systems for each function.
2Reliability
If continuous communication between tracking devices and central station is maintained, then real-time monitoring is achieved, but energy consumption increases
Solution Approach 1:
The tracking devices transmit data at periodic intervals rather than continuously, maintaining reliable monitoring coverage while significantly reducing energy consumption. The system balances communication frequency with power conservation by sending updates at optimized intervals based on operational requirements.
Solution Approach 2:
The system uses event-triggered feedback mechanisms where communication is activated based on specific conditions such as motion detection, geofence violations, or coupling events. This feedback-driven approach ensures reliable monitoring of critical events while minimizing unnecessary transmissions that would consume battery power during idle periods.
3Loss of time
If the trailer tracking device remains active continuously, then immediate detection of events is possible, but battery life is reduced
Solution Approach 1:
The tracking device performs preliminary assessments by remaining in a low-power state and only activating full monitoring functions when specific triggering conditions are met. This preliminary action approach allows the system to quickly transition from idle to active state when needed, minimizing overall power consumption while maintaining rapid event detection capability.
Solution Approach 2:
The system dynamically adjusts its operational state between active monitoring and low-power modes based on real-time conditions. The tracking device can rapidly switch between states, being fully active during critical events and in low-power mode during stable periods, thereby extending battery life while maintaining quick response to important events.
4Loss of information
If comprehensive data collection from all tracking devices is implemented, then complete tracking information is obtained, but data management complexity increases
Solution Approach 1:
The data management system is segmented into modular components that handle different aspects of data collection, processing, and storage independently. Each tracking device operates autonomously to collect and pre-process its own data, then transmits organized information to the central system. This segmentation reduces overall data management complexity while maintaining complete tracking information across all devices.

AI summary
When a cargo trailer is coupled to a truck, a trailer tracking device on the trailer acquires an identifier of a truck tracking device attached to the truck. The trailer tracking device then transmits a message to a central server indicating that the trailer is coupled to the truck, which message includes the identifiers of the two tracking devices. The central server associates the identifiers of the two tracking devices in a database. When the trailer is decoupled from the truck, the trailer tracking device transmits a message to the central server indicating that the trailer is decoupled. The trailer tracking device then goes into a sleep mode until the trailer is again coupled to a truck, a predetermined time interval expires, a motion sensor indicates trailer movement, location coordinates indicate a geofence violation, or a low battery voltage condition occurs. Upon any of these events, the trailer tracking device wakes up and transmits to the central server a message indicating which situation caused the transmission and including the location coordinates of the trailer.
