Cross-Dock Conveyance Robot With Counterweight and Dual Steering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies struggle to efficiently handle and convey freight weighing one ton or more in cross-dock operations, as conventional robots are not designed to manage such heavy loads safely and effectively.
Innovation Solution
An autonomous conveyance robot (ACR) with a lift carriage, counterweight system, and independently steerable front and rear drive assemblies, capable of autonomously handling movable platforms, providing lifting, pulling, and steering capabilities to manage heavy loads in various conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If conventional robots are used to handle freight, then they can easily adapt to light freight (under 1000 lbs.), but they cannot safely and effectively manage heavy loads (one ton or more)
Solution Approach 1:
The robot system changes its operational parameters dynamically - using electric motors for light loads and hydraulic systems for heavy loads. This parameter change allows the same platform to safely handle freight from under 1000 lbs. to one ton or more by selecting the appropriate power source and control mode based on load weight.
2Productivity
If automated conveyance systems are implemented for heavy freight, then productivity increases, but the complexity of the system increases
Solution Approach 1:
The conveyance robot is designed as a universal platform that can handle multiple functions - it can operate in fully automated mode for high productivity, or switch to remote-controlled mode for complex situations. The same hardware platform serves both light and heavy freight operations, reducing overall system complexity while maintaining high productivity capabilities.
3Productivity
If conventional cross-dock methods are used, then the methods are simple and well-understood, but they are inefficient for modern shipping demands
Solution Approach 1:
The system implements dynamic automation where the level of automation adjusts based on operational needs. The robot can fully autonomously perform routine conveyance tasks to maximize productivity, while allowing remote human control for exceptional situations. This dynamic approach balances shipping efficiency with manageable automation complexity.

AI summary
Disclosed herein is an automated conveyance robot (ACR) for conveying movable platforms (MPs) in and out of trailers. A lift carriage at a first end of the ACR is configured to couple to the MP during movement and disengage after movement. A counterweight system at a second end of the ACR counterbalances the ACR during conveyance. The ACR comprises a front drive assembly and a rear drive assembly which are independently steerable to allow for different steering methods. The ACR can function fully automated or can be controlled.
