System for the automatic connection and/or disconnection of the electric power supply and/or data connection for refrigerated containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for connecting and disconnecting refrigerated containers lack flexibility and ease of installation, particularly in situations where reefer racks are not available or are insufficient to meet peak demands, leading to dangerous manual connections and limited scalability.
Innovation Solution
A transportable support structure with integrated mechanical arms and power/data connectivity, allowing for automated connection and disconnection of refrigerated containers, which can operate independently of external power grids and be easily deployed and reconfigured to accommodate varying numbers of containers, using a modular system with electricity generation units and data transmission capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If fixed reefer racks with mechanical arms are used, then automated connection and disconnection is achieved, but the system lacks flexibility and cannot meet peak demands when all stations are occupied
Solution Approach 1:
The patent transforms the static, fixed reefer rack structure into a dynamic, mobile system. The mechanical arm system is mounted on mobile platforms (trucks or containers) that can be repositioned as needed. This allows the automated connection system to adapt to varying storage needs and peak demands by moving to different locations and stacking areas, rather than being confined to fixed stations.
Solution Approach 2:
The patent divides the automated connection system into modular, independent units. Each mobile platform carries its own mechanical arm and power supply equipment, creating self-contained modules that can be deployed independently or in combination. This segmentation allows flexible scaling to meet peak demands by adding more mobile units rather than expanding a fixed infrastructure.
2Adaptability or versatility
If manual connection to ground outlets is used when reefer racks are full, then containers can be powered, but port operators face dangerous working conditions
Solution Approach 1:
The mobile automated connection system performs the connection operation autonomously without requiring port operators to manually handle containers or connectors. The mechanical arm automatically positions and connects the power and data connections, while the system self-manages the positioning and stabilization processes, eliminating human exposure to dangerous conditions.
Solution Approach 2:
The mobile mechanical arm system acts as an intermediary between the power source and the refrigerated containers. Instead of operators directly connecting containers to ground outlets, the automated arm serves as a safe intermediary that handles all physical connection operations, protecting operators from harmful factors while enabling continuous operation during peak demands.
3Extent of automation
If fixed reefer rack structures are built, then automated connection is possible, but the system is bulky and difficult to install and remove
Solution Approach 1:
The patent replaces static, permanently installed structures with dynamic, mobile platforms. The mechanical arm system, power supply equipment, and support structures are mounted on movable chassis that can be easily transported and repositioned. This transforms the installation process from a complex, permanent construction project into a simple deployment of mobile units that can be set up and removed as operational needs change.
