Stacking Storage Layout With Cross-Row Loading Vehicle Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stacking storage arrangements require multiple loading vehicles to manage containers across rows, increasing construction costs and operational inefficiencies due to the need for separate vehicles for each row.
Innovation Solution
A transverse transport device allows loading vehicles to move between rows, eliminating the need for separate vehicles per row by using a transverse transport trolley and control device to optimize container placement and access based on turnover frequency, thereby reducing the number of placement-into-storage/removal-from-storage arrangements and enhancing operational efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple loading vehicles are assigned to each row for container management, then container access and placement efficiency is improved, but construction costs and system complexity increase due to requiring more vehicles and infrastructure
Solution Approach 1:
Multiple loading vehicles from different rows are merged onto a single transverse transport device that moves along a rail system spanning across rows. This allows one vehicle to serve multiple rows sequentially, reducing the total number of vehicles needed while maintaining container access capability across the entire storage arrangement.
Solution Approach 2:
The transverse transport device serves multiple functions: it transports loading vehicles between rows, provides a shared access pathway for multiple container stacks, and enables a single vehicle to perform operations across different rows. This multi-functionality replaces the need for dedicated vehicles for each row.
2Productivity
If separate loading vehicles are assigned to each row, then container placement and removal operations can occur simultaneously in different rows, but the cost and space requirements for additional vehicles and infrastructure increase
Solution Approach 1:
The system merges the functionality of multiple dedicated vehicles into a single vehicle that shares a common transverse transport infrastructure. This reduces construction costs for vehicle procurement, maintenance facilities, and training, while the rail system provides a cost-effective shared transport pathway.
Solution Approach 2:
The transverse transport device enables continuous operation by allowing the loading vehicle to move sequentially between rows without idle time. While the vehicle serves one row, other operations can be prepared in advance, and the vehicle can immediately transition to the next row, maintaining continuous productive action.
3Ease of operation
If the transverse transport device is arranged inside the loading space, then container access is simplified, but it blocks access to container receiving spaces and reduces available stacking area
Solution Approach 1:
The transverse transport device is extracted from the internal loading space and repositioned to the periphery, where it runs along the outer perimeter of the container receiving spaces. This extraction eliminates the blocking problem while maintaining its transport function, preserving 100% of the internal stacking area.
Solution Approach 2:
The transverse transport device is positioned in a different spatial dimension - along the perimeter rather than through the center of the loading space. This dimensional repositioning allows the vehicle to access container receiving spaces from the sides without obstructing the vertical stacking area or the horizontal movement of containers within the loading space.
4Ease of manufacture
If fewer placement-into-storage/removal-from-storage arrangements are used, then construction costs are reduced, but operational flexibility and access to containers in certain rows may be limited
Solution Approach 1:
The transverse transport device creates a universal access pathway that allows a single placement-into-storage/removal-from-storage arrangement to serve multiple rows. The loading vehicle can access any row through the transverse transport system, providing operational flexibility equivalent to having dedicated arrangements for each row, but with fewer physical arrangements needed.
Solution Approach 2:
The transverse transport device acts as an intermediary between the limited number of placement-into-storage/removal-from-storage arrangements and the multiple container rows. It mediates access by transporting the loading vehicle to the appropriate row, enabling flexible container operations despite having fewer direct access points.

AI summary
A stacking storage arrangement having multiple container receiving spaces that are arranged in multiple rows and columns, wherein a loading space in which at least one loading vehicle can be moved is arranged below the container receiving spaces. The operation of a stacking storage arrangement of this type is configured to be economical. For this purpose, a transverse transport device is provided with which the loading vehicle can be moved between positions that are respectively assigned to a row.
