Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for tracking intermodal shipping containers face challenges due to electromagnetic interference from stacking, which prevents data transmission, and require physical modifications that compromise the container's structure and integrity.
Innovation Solution
A system that enables data communication from sensors inside a container to an external communications unit on the outside without drilling holes or physical connections, using wireless communication and a mesh network to transmit data through stacked containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless communication is used to transmit data through stacked containers, then data transmission continuity is improved, but electromagnetic interference from stacking causes signal blockage
Solution Approach 1:
The patent employs mesh network technology where intermediate nodes (other tracking devices or relay points) forward data packets when direct communication is blocked by stacked containers. This intermediary approach allows data to route around electromagnetic interference zones, maintaining transmission continuity despite signal blockage from metal container stacking.
Solution Approach 2:
The system dynamically adjusts communication strategies based on real-time signal conditions. When electromagnetic interference is detected from container stacking, the system automatically switches between different communication modes (direct wireless, mesh relay, or alternative routing) to maintain data transmission, making the communication system adaptable to varying interference conditions.
2Ease of operation
If physical connections are made through drilling holes in containers, then data communication is enabled, but container structure and integrity are compromised
Solution Approach 1:
The patent replaces mechanical/physical connection methods (drilling holes, running cables through container walls) with wireless communication technology. Tracking devices use wireless transceivers to communicate container status data without any physical penetration or modification of the container structure, thereby enabling data communication while preserving structural integrity.
Solution Approach 2:
The communication functionality is extracted as a separate external system rather than being integrated into the container structure itself. Tracking devices are positioned outside or on the container surface, eliminating the need to embed communication components within the container walls through drilling or modification.
3Productivity
If tracking devices are installed on containers, then real-time monitoring is achieved, but device management and data security become complex
Solution Approach 1:
The patent implements a universal centralized server platform that handles multiple functions: data collection from various tracking devices, authentication and authorization management, encryption and decryption operations, and alert generation. This multi-functional server consolidates complex management tasks into a single system, simplifying the management of distributed tracking devices while maintaining real-time monitoring capabilities.
Solution Approach 2:
The system incorporates feedback mechanisms where the centralized server continuously monitors data from tracking devices and automatically generates alerts when anomalies are detected. This automated feedback loop reduces manual management complexity by providing real-time notifications and enabling proactive response to container events without requiring constant human oversight of each device.

AI summary
A method for managing data includes: initiating, by a communications unit (CU) processor of a CU, a communication module (CM); establishing, by the CM, a communication link (CL) to a management infrastructure (MI) over a network; notifying, by the CM, the CU processor about the CL; after the notifying: framing, by the processor, data that is received from a proximity wireless communication module (PWCM) based on a protocol of the CL to generate framed data, in which the PWCM has received the data from a second PWCM; transmitting, by the processor, the framed data to the MI over the CL; making, by the processor, a determination that the CL needs to be terminated; directing, by the processor, a communications manager of the CU to terminate the CL and to manage power consumption in the CU.
