Container Vehicle Loading Rack With Winch-Locked Security Ramp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle shipping systems are unsafe, inefficient, and lack effective theft prevention, as they require manual operation inside shipping containers, are prone to accidents, and offer inadequate security measures against theft and smuggling.
Innovation Solution
A self-contained mechanized vehicle storage system that uses a ramp, winches, and trolleys to load and secure vehicles within shipping containers without an operator inside, providing enhanced security through automatic operation and theft prevention by locking the ramp inside the container during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional shipping methods require the shipping container to be modified on the outside (cutting doors), then vehicles can be loaded and unloaded, but security is compromised and theft prevention is weakened
Solution Approach 1:
The system divides the container interior into functional zones: a loading zone with the opening, a storage zone with racks, and a secured zone. The ramp is segmented into movable and fixed portions, allowing controlled access while maintaining security. This segmentation enables vehicle loading/unloading through the existing door without modifications while maintaining container integrity and security.
Solution Approach 2:
The ramp acts as an intermediary element between the exterior loading area and the interior storage area. It provides a controlled transition path for vehicles to enter and exit the container through the existing door opening, eliminating the need to cut doors while maintaining security through its locking mechanism.
2Productivity
If raised racks are used to lift vehicles in the air within the container, then another vehicle can be put underneath, but the system becomes dangerous and unstable
Solution Approach 1:
The system incorporates safety features that prevent catastrophic failure: vehicles are secured with wheel straps before being elevated, the racks have support structures distributed along their length, and the system is designed so that even if one component fails, other components maintain support. This beforehand cushioning approach allows multi-level storage while mitigating the dangers of vehicle elevation.
Solution Approach 2:
The rack system uses different structural configurations at different locations: heavier support structures where vehicles are elevated, strategic placement of wheel straps at critical points, and varying rack heights based on local requirements. This localized optimization enables efficient space utilization while maintaining stability throughout the system.
3Reliability
If workers manually tie down and secure each wheel of the vehicle inside the container, then vehicles are secured, but the process becomes dangerous and tedious
Solution Approach 1:
The system is designed to minimize manual intervention: vehicles drive onto the ramp and position themselves, the winch automatically secures vehicles to the rack, and wheel straps are applied through a simplified process. The mechanized winch system performs the securing function that would otherwise require manual effort, making the process safer and less tedious while maintaining reliable vehicle securing.
Solution Approach 2:
The manual mechanical process of tying down wheels is replaced with a mechanized winch system that automatically secures vehicles to the rack. The winch uses a cable and drum mechanism to pull vehicles onto the rack and secure them in place, eliminating the need for workers to manually tie down each wheel inside the container.
4Ease of operation
If the container door remains accessible during transport, then loading and unloading is possible, but theft prevention and smuggling prevention are inadequate
Solution Approach 1:
The ramp is designed as a dynamic security element: during loading/unloading operations, the ramp is in an extended position providing access; during transport, the ramp folds into a locked position that blocks the opening. This dynamic transformation allows the system to adapt between operational mode (access required) and security mode (access prevented), effectively addressing both ease of operation and theft prevention.
Solution Approach 2:
The ramp locking mechanism is designed to prevent potential theft attempts before they can occur. By automatically locking the ramp in a position that blocks the container opening during transport, the system creates a preliminary barrier that deters and prevents theft and smuggling activities before they can be initiated.
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
The system ensures safe, efficient, and secure transportation of vehicles by eliminating manual handling risks, reducing carbon emissions, and providing robust theft prevention by locking the ramp inside the container, thus preventing unauthorized access.
Implementation Method 1
A winch is mounted in the container and pulls the trolley and vehicle up the ramp and across the rack
Implementation Method 2
The ramp has caster tracks that guide the trolley as it rolls up and into the container

AI summary
A self-contained, mechanized automobile transport system used to load, secure, transport, and unload units for vehicle shipments on ships, on rail cars, on semi-truck trailers, or any other shipping method. The system may include a rack affixed to the floor of a container, a ramp, a ramp adapter, one or more winch mount assemblies, one or more trolleys, one or more winches, and a power source for providing power to the one or more winches via an electrical system. A vehicle may be loaded and secured onto one or more trolleys, and the one or more winches pulls the first vehicle into the container. The trolleys interact with the winch mount assemblies to secure the vehicle in the container.
