Mobile Inventory Storage Classification and Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern inventory systems face challenges in responding quickly to diverse inventory requests, leading to increased backlogs due to slow response times, which are exacerbated by the physical location of storage spaces within the system.
Innovation Solution
A mobile inventory system comprising mobile drive units that move inventory holders between locations, managed by a module that classifies holders and storage locations to optimize task completion times and distribute work efficiently, allowing for flexible and scalable storage solutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If inventory items are stored in fixed storage spaces, then storage organization is simple, but response time to inventory requests increases
Solution Approach 1:
The patent implements mobile drive units that can dynamically move inventory holders between different storage locations based on request patterns. The system transitions from static fixed storage to dynamic reconfigurable storage, allowing frequently requested items to be positioned closer to pickup points while maintaining organizational simplicity through automated management.
Solution Approach 2:
The storage system is divided into multiple independent inventory holders that can be individually moved by separate mobile drive units. This segmentation allows the system to optimize storage locations for different inventory items independently, reducing overall response time without requiring complete system reconfiguration.
2Productivity
If mobile drive units are used to move inventory holders, then response time decreases, but system complexity increases
Solution Approach 1:
The mobile drive units are designed as multi-functional components that can transport various types of inventory holders to different destinations within the storage system. This universality allows a single mobile unit to perform multiple tasks, increasing productivity without proportionally increasing the number of components in the system.
Solution Approach 2:
The system incorporates automated classification and routing logic that enables mobile drive units to autonomously determine optimal storage locations and movement paths. This self-service capability reduces the need for complex external control mechanisms, balancing increased productivity with manageable system complexity.
3Loss of time
If storage locations are optimized for frequently requested items, then response time improves, but storage space utilization may decrease
Solution Approach 1:
The system implements periodic reclassification and repositioning of inventory holders based on changing request patterns. Storage locations are not permanently assigned but are dynamically adjusted over time, allowing the system to maintain high space utilization while providing fast access to currently frequently requested items through regular optimization cycles.
Data Source
AI summary
A method for storing inventory items in an inventory system includes detecting that an inventory holder is available for storage and determining a classification of the inventory holder. The method also includes determining a classification of each of a plurality of storage locations and selecting a storage location for the inventory holder based, at least in part, on the classification of the inventory holder and the classification of the selected storage location. The method additionally includes transmitting information identifying the storage location to a mobile drive unit associated with the inventory holder.
