Chassis-less Dual Container Trailer with Independent Hoist Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual container trailers face logistical issues with inline positioning, leading to inefficient loading and unloading processes and increased manufacturing costs, as they often require complex mechanisms for handling multiple containers.
Innovation Solution
A dual container trailer system featuring a main trailer frame with a sub-frame and independent hoist systems for pivoting the main and sub-frames, allowing for separate inclination of each container for loading and unloading, and a chassis-less design that eliminates the need for a separate transport frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If inline positioning of containers is used on dual container trailers, then the trailer can transport multiple containers, but logistical problems arise and loading/unloading speed decreases
Solution Approach 1:
The trailer is divided into two independent container handling systems: a main frame with first hoist system for the first container, and a sub-frame with second hoist system for the second container. Each hoist system operates independently, allowing simultaneous or separate loading/unloading operations, thereby maintaining high productivity while transporting multiple containers
Solution Approach 2:
The sub-frame is designed to be movable relative to the main frame through the second hoist system, which can pivot the sub-frame between a stowed position and an extended position. This dynamic configuration allows flexible positioning of the second container, enabling efficient loading/unloading operations without compromising the transport of multiple containers
2Adaptability or versatility
If complex mechanisms are used for handling multiple containers, then container handling capability is improved, but manufacturing costs and device complexity increase
Solution Approach 1:
Each hoist system (first and second) is designed as a universal container handling mechanism that can independently perform loading, unloading, and positioning operations. The sub-frame structure serves multiple functions: supporting the second container, providing a mounting base for the second hoist system, and enabling positional adjustment. This multi-functionality achieves versatile container handling without requiring overly complex specialized mechanisms
Solution Approach 2:
The second hoist system is coupled between the main frame and the sub-frame, creating a nested configuration where the sub-frame is positioned within the overall trailer structure. When the sub-frame is in the stowed position, the second hoist system is compactly arranged within the trailer body, reducing complexity while maintaining full handling capability when extended

AI summary
A system for transporting containers includes a trailer frame with independent hoist systems for loading and unloading multiple containers. The trailer frame supports the containers during transport, inclines to load/unload the containers, and supports a tilting sub-frame that loads/unloads a container. Thus, the system is chassis-less.
