Solution Overview

Problem

Real-time inventory management is challenging in complex online retail operations due to broad warehouse networks, multiple vendors, and customized product listings, leading to inventory update delays and supply chain discontinuities.

Innovation Solution

A system and method for dynamic inventory balancing using virtual bundles, where a processor configures operations to receive inventory data feeds, store virtual bundles, and update them based on client orders, rebalancing to maximize diversity and adapt to demand, employing machine-learning models for forecasting and real-time updates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional inventory update cycles are used, then system complexity is reduced, but inventory accuracy and real-time responsiveness deteriorate

Engineering Contradiction:
Improveinventory accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments inventory management into virtual bundles that group items with similar demand patterns. Each bundle is managed independently with its own inventory tracking, allowing real-time updates without requiring complete system reprocessing. This segmentation enables precise inventory measurement while reducing overall system complexity through modular management.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts inventory allocation across virtual bundles based on real-time demand signals and forecasted patterns. Inventory levels are continuously optimized through machine learning models that respond to changing conditions, enabling accurate real-time inventory management without rigid fixed cycles. The dynamic rebalancing process maintains accuracy while adapting to varying operational conditions.

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If real-time inventory tracking is implemented, then inventory accuracy improves, but network traffic and processing load increase

Engineering Contradiction:
Improveinventory accuracyVSAvoidnetwork traffic
Core Design Contradiction:
Measurement precisionVSLoss of energy

Solution Approach 1:

The system merges inventory data from multiple fulfillment centers into unified virtual bundles that aggregate items with similar characteristics. By combining data at the bundle level rather than tracking each item individually across all centers, the system achieves accurate real-time inventory visibility while reducing the volume of network traffic required for data synchronization and processing.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system creates virtual representations of inventory data through machine learning models that forecast demand patterns. These virtual models allow the system to simulate and plan inventory allocation without constantly querying actual fulfillment center stock levels, reducing network traffic while maintaining accurate inventory predictions and real-time responsiveness.

Inventive Principle:
Principle #26Copying

3Speed

If inventory is updated continuously, then real-time responsiveness improves, but processing time and computational resources increase

Engineering Contradiction:
Improvereal-time responsivenessVSAvoidprocessing time
Core Design Contradiction:
SpeedVSLoss of time

Solution Approach 1:

The system performs preliminary inventory allocation decisions by pre-calculating optimal bundle compositions and forecasting future demand patterns. Machine learning models analyze historical data to predict which items should be grouped together and where they should be allocated before actual orders are placed. This preliminary action enables real-time responsiveness to actual customer orders without requiring extensive real-time processing, as the foundation is already established through advance planning.

Inventive Principle:
Principle #10Preliminary action

AI summary

A computer-implemented system for dynamic inventory balancing including at a processor and a memory device comprising instructions that when executed configure the processor to perform operations. The operations including receiving an inventory data feed from at least one fulfillment center, storing (in a database) a plurality of virtual bundles with associated grouping numbers and quantities—the plurality of virtual bundles having item bundles grouping two or more of a same item in the inventory data. The operations also include exposing the database to queries from a seller portal through at least one of RESTful service, a queue based system, an index, or an object table and receiving a client order, the client order comprising a bundle selection from the plurality of virtual bundles, and updating the plurality of virtual bundles by rebalancing the plurality of virtual bundles and corresponding associated quantities based on the bundle selection.
