Stack Storage Arrangement Row Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stacking bearing arrangements face challenges in organizing the operation economically, particularly in managing the movement and storage of containers with varying transshipment frequencies.
Innovation Solution
The solution involves dividing the stacking bearing arrangement into partial units, each with its own series of container absorption rooms and a dedicated loading vehicle keeping position. This allows for efficient control of loading vehicles, which can only move within assigned series, thereby simplifying operations and increasing security.

Engineering Contradiction Analysis
1Ease of operation
If the stack storage arrangement is divided into multiple partial units with dedicated loading vehicle holding positions, then the control complexity is reduced and operational efficiency is improved, but the device complexity increases due to multiple holding positions and transfer arrangements
Solution Approach 1:
The stack storage arrangement is divided into multiple partial stack storage arrangements, each with its own dedicated loading vehicle holding position. This segmentation allows each loading vehicle to operate independently within its assigned row, simplifying control logic and reducing the complexity of managing loading vehicles across the entire system.
Solution Approach 2:
Storage/retrieval arrangements are introduced as intermediary systems between the loading vehicles and the container receiving spaces. These intermediaries handle the transfer of containers at transfer positions, decoupling the loading vehicle operations from direct access to storage locations and further simplifying control.
2Reliability
If loading vehicles are restricted to move only within assigned rows, then the control system becomes simpler and operational safety is improved, but the flexibility to access any container receiving space directly is reduced
Solution Approach 1:
The system is segmented into multiple rows, with each loading vehicle assigned to a specific row. This segmentation improves safety by limiting the operational scope of each loading vehicle, reducing the risk of collisions and conflicts. The restricted movement within assigned rows is compensated by the storage/retrieval arrangements that can transfer containers between different rows.
Solution Approach 2:
The storage/retrieval arrangements act as intermediaries that enable indirect access to container receiving spaces in other rows. When a loading vehicle needs to access a container in a different row, the container is first transferred to the storage/retrieval arrangement, which then moves it to the appropriate row. This maintains safety while preserving access flexibility.
3Productivity
If containers with high turnover frequency are positioned in lower areas and closer to loading vehicle stop positions, then the retrieval time is reduced and productivity is improved, but the system complexity increases due to dynamic position determination
Solution Approach 1:
The control device determines the optimal position for containers based on their turnover frequency in advance, before retrieval operations begin. Containers with high turnover frequency are pre-positioned in lower areas and closer to loading vehicle stop positions, while less frequently accessed containers are placed in higher or more distant positions. This preliminary arrangement minimizes retrieval time and maximizes productivity.
Solution Approach 2:
The system dynamically adjusts container positions based on turnover frequency data. The control device continuously monitors and determines the optimal positioning strategy, adapting the storage arrangement to changing access patterns. This dynamic approach ensures that frequently accessed containers are always in optimal positions for quick retrieval.

AI summary
A stacking storage arrangement (1) is described, comprising several container receiving areas (2) arranged in multiple rows (3) and columns (4). A loading area is located below the container receiving areas (2), within which loading vehicles can move. The aim is to operate such a stacking storage arrangement (1) economically. For this purpose, each row (3) is assigned its own loading vehicle stopping position (15), which is located outside the container receiving areas (2).
