Overhead Container Carrier Alignment for Congestion-Free Port Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for transferring intermodal shipping containers between transportation modes are time-intensive, require large ground space, and contribute to port congestion, while existing overhead rail systems face challenges in efficiently loading/unloading containers of varying sizes.
Innovation Solution
An overhead transport system comprising a suspended railway with motorized carriers, trolleys, and a control system that includes a chassis/beam for container handling, bumpers for collision prevention, and a deflection system, allowing for efficient transfer and alignment of containers using an overhead rail transportation system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ground-level mechanical machines (cranes, trucks, forklifts) are used to transfer containers, then containers can be moved between transportation modes, but large amounts of ground space are required and port congestion increases
Solution Approach 1:
The patent transitions container transfer operations from the ground level to an overhead three-dimensional space. The overhead rail system allows containers to be moved above the port area, effectively utilizing the vertical dimension and eliminating the need for extensive ground maneuvering space. This dimensional shift resolves the contradiction by maintaining high transfer efficiency while dramatically reducing ground space requirements.
2Productivity
If ground-level machines are used for container transfer, then containers can be moved, but the process is time-intensive and leads to port congestion and container backlog
Solution Approach 1:
The overhead rail system enables continuous container transfer operations without the interruptions typical of ground-level machinery. Multiple containers can be moved simultaneously along the overhead rails, and the system maintains constant motion rather than requiring repeated stopping and positioning maneuvers. This continuous operation dramatically reduces transfer time and eliminates port congestion.
3Area of stationary object
If overhead rail transport systems are used, then ground space is reduced and port congestion decreases, but challenges arise in efficiently loading/unloading containers of various sizes
Solution Approach 1:
The overhead rail system incorporates dynamic, adjustable components that can adapt to different container sizes. The carriers and loading mechanisms are designed with movable parts that can be reconfigured to accommodate standard and non-standard container dimensions. This dynamic adaptability allows the system to maintain versatility across different container types while preserving the space-saving overhead configuration.
4Productivity
If traditional ground-level transfer methods are used, then containers can be moved between modes, but fossil fuels are burned and operational efficiency is reduced
Solution Approach 1:
The patent replaces fossil fuel-powered mechanical machines (diesel cranes, trucks, forklifts) with an electrically-powered overhead rail system. The electric motors driving the overhead carriers eliminate direct fossil fuel combustion, significantly reducing energy loss and improving operational efficiency. This substitution maintains high productivity while dramatically reducing carbon emissions and energy waste.

AI summary
An overhead transport system includes a suspended railway and a motorized carrier configured to travel along the suspended railway. The motorized carrier includes a motorized trolley configured to move the motorized carrier along the suspended railway, chassis/beam configured to carry an object below the motorized trolley, and a bumper and deflection system configured to prevent the object from contacting another object.
