Dynamic Racking Structure for High-Density Warehousing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional racking structures, whether low- or high-density, do not scale efficiently with the number of items stored, leading to inefficiencies in storage capacity, throughput, and the use of automated picking mechanisms in warehouses.
Innovation Solution
A high-density storage warehousing system incorporating a dynamic racking structure with automated pickers and a controller that communicates to position bins within compartments, allowing for efficient retrieval and return of items by automating the transfer between racking structures and pickers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a high-density racking structure is used to increase storage capacity, then the number of items stored increases, but the throughput and efficiency of automated picking mechanisms deteriorates
Solution Approach 1:
The system divides the racking structure into multiple compartments, each independently managed by its own bin handler. This segmentation allows parallel operation of multiple compartments, increasing overall throughput while maintaining high storage density. Each compartment can be accessed and serviced independently without blocking other compartments.
Solution Approach 2:
The patent implements dynamic bin handlers that can automatically reposition bins within compartments and dynamically adjust compartment configurations. This dynamic capability allows the system to optimize both storage density and access efficiency by moving bins to optimal positions based on retrieval frequency and current compartment state.
2Productivity
If a low-density racking structure is used to improve throughput, then the efficiency of automated picking mechanisms improves, but the storage capacity deteriorates
Solution Approach 1:
The system utilizes vertical space by implementing multi-level compartments within each racking unit. By stacking compartments vertically and using bin handlers to access bins at different heights, the system dramatically increases storage capacity without increasing the horizontal footprint, thereby maintaining high throughput while maximizing storage density.
Solution Approach 2:
Bins are nested within compartments, and multiple compartments are nested within single racking units. This nested structure allows maximum utilization of available space while maintaining organized, accessible storage. The bin handlers can access nested bins without disrupting the overall compact structure.
3Ease of operation
If conventional racking structures are used, then the system is simple to operate, but the system does not scale efficiently with the number of items stored
Solution Approach 1:
The system implements self-service through automated bin handlers that independently manage their respective compartments. Each bin handler autonomously positions bins, manages compartment contents, and communicates with the central controller. This self-service capability allows the system to scale to many compartments without proportionally increasing operational complexity, as each unit manages itself.
Solution Approach 2:
The bin handlers are designed as universal, multi-functional units that can operate in any compartment configuration. The same bin handler design can serve different compartment sizes, shapes, and locations, allowing the system to scale efficiently by repeating the same proven module rather than designing custom solutions for each expansion scenario.

AI summary
The disclosure is directed at a high-density warehousing system that includes a set of high-density racking structures, each of the high-density racking structures including a set of compartments for housing a set of bins. The system can also include an automated picker for retrieving a requested bin or returning a returned bin to a designated compartment within the set of high-density racking structures and a control system for communicating compartment location information, the compartment location information associated with the designated compartment. Based on the compartment location information, the automated picker retrieves or returns the bin to the designated compartment.
