Connectable Inventory Holders for High-Throughput Group Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern inventory systems face challenges in efficiently utilizing time and space due to growing demand and tighter shipping schedules, particularly in managing large queues of inventory holders, which often require a trade-off between using more resources for higher costs or fewer resources for lower throughput.
Innovation Solution
The implementation of connectable inventory holders that can be transported individually or connected to form groups, allowing fewer mobile drive units to manage larger queues and increase throughput by enabling efficient assembly and disassembly of groups under the control of a management module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If more mobile drive units are used to manage inventory holders, then throughput is improved, but economic cost increases
Solution Approach 1:
Multiple inventory holders are connected together to form groups, allowing a single mobile drive unit to transport multiple holders simultaneously. This merging approach increases throughput without proportionally increasing the number of mobile drive units, thereby reducing economic cost while maintaining productivity.
Solution Approach 2:
The system segments inventory holders into connectable groups that can be assembled and disassembled dynamically. This segmentation allows flexible configuration where mobile drive units can efficiently manage varying numbers of connected holders based on demand, optimizing resource utilization without requiring additional units for every individual holder.
2Adaptability or versatility
If inventory holders are transported individually, then flexibility is improved, but the number of mobile drive units required increases
Solution Approach 1:
The system implements dynamic connectivity where inventory holders can be connected or disconnected based on real-time operational needs. This dynamic configuration allows the system to adapt to varying throughput requirements while optimizing the utilization of mobile drive units, reducing the total number needed compared to always transporting holders individually.
Solution Approach 2:
Each inventory holder is equipped with connection modules that enable it to function both independently and as part of a connected group. This multi-functionality allows the same hardware to adapt to different operational modes, providing flexibility without requiring separate specialized equipment for individual versus group transport.
3Quantity of substance
If fewer mobile drive units are used, then economic cost is reduced, but throughput decreases
Solution Approach 1:
By merging multiple inventory holders into connected groups, a single mobile drive unit can handle the transport of multiple holders, effectively multiplying its productivity. This approach allows the system to maintain high throughput with fewer units, reducing economic cost while preserving productivity.
4Productivity
If connection modules are added to inventory holders, then group transport capability is improved, but device complexity increases
Solution Approach 1:
The connection modules are designed to enable inventory holders to self-connect and self-dock with other holders and with mobile drive units without requiring complex external control mechanisms. This self-service approach provides group transport capability while minimizing the increase in device complexity by using straightforward mechanical or magnetic connection interfaces.

AI summary
A system includes a first mobile drive unit (20a) and a second mobile drive unit. The first mobile drive unit is operable to dock with a first item holder (30a) at a first end of a column of connected item holders. The second mobile drive unit (20b) is operable to dock with a second item holder at a second end (30b) of the column of connected item holders. The system also includes a management module (15) that is operable to instruct the first mobile drive unit and the second mobile drive units to transport the column of connected item holders from a first location to a second location.
