Movable Platform Roller Actuation for Single-Move Trailer Unloading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional method of loading and unloading freight in semi-trailers is inefficient, requiring multiple trips by forklifts and posing safety risks due to the driver entering the trailer, which leads to wasted time and resources.
Innovation Solution
A movable platform system with a mechanical actuation assembly that allows forklifts or automated guided vehicles to deploy and retract roller assemblies, enabling the platform to be easily maneuvered in and out of trailers without the driver needing to enter, using an actuating attachment for deployment and retraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a forklift driver enters the trailer to unload pallets, then the unloading process can be completed, but the driver's safety is compromised and the process time increases
Solution Approach 1:
The patent introduces a movable platform as an intermediary device between the forklift and the trailer interior. The platform extends into the trailer to receive pallets directly from the trailer floor, eliminating the need for the driver to enter the trailer. The platform is controlled by the driver from outside the trailer, serving as a mediator that transfers goods without requiring human entry into the hazardous zone.
2Productivity
If a forklift makes multiple trips to unload each pallet, then all pallets can be removed, but empty carries waste energy and reduce productivity
Solution Approach 1:
The patent combines multiple unloading operations into a single continuous action. The movable platform can receive multiple pallets in sequence without requiring the forklift to return to its starting position after each pallet. The platform acts as a buffer that accumulates pallets, allowing the driver to unload several pallets in one continuous operation, thereby merging what would otherwise be multiple separate trips into a single productive cycle.
3Adaptability or versatility
If the trailer is not connected to the dock, then the trailer remains mobile and accessible, but the forklift driver must exercise caution when entering the trailer
Solution Approach 1:
The movable platform serves as a safe intermediary that eliminates the need for the driver to enter the trailer. The platform can be extended into the trailer to receive pallets while the driver operates it from the safety of the exterior. This mediator approach maintains the trailer's mobility and accessibility while completely removing the driver from the hazardous environment inside the trailer.
4Productivity
If a movable platform with roller assemblies is used, then single-move loading and unloading is enabled, but the device complexity increases
Solution Approach 1:
The movable platform is segmented into distinct functional modules: a support structure, deployable roller assemblies, and a control mechanism. The roller assemblies can be independently deployed and retracted, allowing the platform to transition between different operational states. This segmentation enables the complex functionality of single-move loading while maintaining manageable system architecture through modular design.
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
Enables efficient single-move loading and unloading of freight, reducing the need for empty forklift trips and enhancing safety by allowing the platform to be managed externally, thus improving operational efficiency and reducing risks.

AI summary
Disclosed herein is a movable platform (MP) for moving freight during cross-dock operations. The MP comprises a mechanical actuation assembly used to deploy a plurality of roller assemblies used for moving the MP. Also disclosed is an actuating attachment used to deploy the mechanical actuation assembly of the MP. The actuating attachment can be attached to a conveyance vehicle, such as a forklift, or built in to an automated guided vehicle.
