Detachable Roller Transport Unit for Modular Freight Logistics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller transport units are inefficient in handling and storing goods with different storage requirements due to their fixed two-stack design, leading to time-consuming unloading and mixing issues, especially in confined spaces.
Innovation Solution
A roller transport unit composed of two detachable sub-units with a base and wheels, allowing for flexible handling by connecting or separating the units and using adjustable locking bars to secure stacks of boxes, enabling independent movement of sub-units to different locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed two-stack design is used on roller transport units, then the cargo space utilization is optimized for standard configurations, but the flexibility to handle goods with different storage requirements is reduced
Solution Approach 1:
The roller transport unit is divided into two separate detachable sub-units, each capable of independently carrying a stack of boxes. This segmentation allows the sub-units to be separated and transported to different destinations based on storage requirements, thereby increasing adaptability while maintaining manageable structural complexity through modular design
2Productivity
If two stacks of boxes are arranged on a single roller transport unit, then the transport efficiency is improved, but the time required to unload and separate goods for different storage locations increases
Solution Approach 1:
By separating the transport unit into two detachable sub-units, each carrying its own stack of boxes, the system maintains the productivity benefit of transporting multiple stacks simultaneously while enabling quick separation at the destination. This eliminates the time-consuming process of unloading and redistributing boxes from a single unified platform to multiple destinations
3Quantity of substance
If the roller transport unit is designed to accommodate two stacks of boxes, then the load capacity is increased, but the maneuverability in confined spaces is reduced
Solution Approach 1:
The transport system is segmented into two separate sub-units that can be detached from each other. When full load capacity is needed, both sub-units are connected and transported together. When maneuverability in confined spaces is required, the sub-units can be separated and handled independently, providing flexibility to adapt to space constraints while maintaining high load capacity capability
Solution Approach 2:
The system transitions from a static fixed design to a dynamic reconfigurable structure. The detachable connection between sub-units allows the system to change its configuration based on operational requirements - connected for high-capacity transport, separated for maneuverability in confined spaces

AI summary
A roller transport unit (1) for goods used in freight logistics has a base (2). A support surface is formed on the upper surface (3) of the base. The roller transport unit (1) comprises two sub-units (1a, 1b), each with a base section (2a, 2b) forming a support surface. The sub-units (1a, 1b) are joined together by their base sections (2a, 2b) to form the base (2) and are detachably connected to one another. At least three wheels (5) are arranged below each of the base sections (2a, 2b).Each of the connectable subunits (1a, 1b) has a first coupling means, and a fixing element is provided which is movable relative to the subunits (1a, 1b) along a bolt direction from a release position to a fixing position. This fixing element is designed to correspond to the first coupling means and, in conjunction with the first coupling means, creates a second coupling means that detachably fixes the two subunits (1a, 1b). The corresponding first and second coupling means are each formed from a pair of a bolt pin (6) and a bolt recess, the bolt recess having a cross-section that tapers in the bolt direction.
