Multi-level Inventory Management System for Real-time Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Online retailers face challenges in managing inventory due to constant flux in product quantities, as existing systems fail to synchronize physical and available inventory levels in real-time, leading to limitations in sales and potential overselling.
Innovation Solution
A multi-level inventory management system that tracks and manipulates inventory quantities across bin, warehouse, and aggregate levels, using a network of servers and devices to ensure real-time synchronization of physical and available inventory, allowing for accurate tracking and allocation of inventory across multiple sales channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical inventory counting is performed in a brick and mortar store, then inventory accuracy is improved, but business operations must be halted
Solution Approach 1:
The patent replaces manual physical inventory counting with automated optical scanning systems (barcode scanners, RFID readers) that can continuously track inventory without interrupting store operations. Sensors and cameras capture item movements automatically, eliminating the need for manual counting that would require closing the store.
Solution Approach 2:
The system introduces an intermediary layer of automated tracking technology between the physical inventory and the inventory management system. This intermediary continuously monitors and reports inventory changes in real-time, enabling accurate inventory data collection without requiring manual intervention or business interruption.
2Reliability
If inventory is allocated to specific sales channels, then overselling is prevented, but inventory availability for sale is reduced
Solution Approach 1:
The system implements dynamic inventory allocation that automatically adjusts available inventory levels based on real-time order status, fulfillment progress, and sales channel demand. Inventory is reserved for pending orders but remains visible and allocable to other channels until the reservation is confirmed or cancelled, maximizing inventory utilization while preventing overselling.
Solution Approach 2:
The system performs preliminary inventory reservations when orders are placed but before fulfillment is complete. This preliminary action reserves inventory to prevent overselling while allowing the inventory to remain available for allocation to other channels if the original order is cancelled or fulfilled from different stock.
3Measurement precision
If real-time inventory tracking is implemented, then inventory synchronization is improved, but system complexity increases
Solution Approach 1:
The system segments inventory tracking into discrete, standardized events (item received, item picked, item packed, item shipped, item returned) that are automatically captured by sensors and scanners. This segmentation simplifies the complexity by breaking down continuous tracking into manageable, automated discrete events that can be processed independently and reliably.

AI summary
A computer-implemented method for real-time and continuous inventory management using a multi-level inventory management system comprising peripheral device(s) in data communication with some number of warehouse server(s), aggregation server(s), and sales channel server(s). A warehouse server may employ real-time physical inventory parameters received from a peripheral device to manage stock keeping unit (SKU) counts and locations as shipping orders, purchase orders, and bin transfer orders are serviced. An aggregation server may compile physical it parameters received from warehouse server(s) into available inventory used to service sales orders, reserve orders, and pre-sell orders. An aggregation server may also modify available inventory to address the status of servicing warehouses (e.g., unsellable, sellable, and dropship).
