Solution Overview

Problem

In high-volume product delivery services, accurately determining the availability of goods and estimating delivery times for items in transit is challenging, as existing systems often consider items out of stock and fail to account for real-time location, leading to inaccurate representations and longer delivery times.

Innovation Solution

Implementing a virtual fulfillment center system that uses dynamic geo-tracking and machine learning algorithms to determine the real-time location of items in transit, allowing for accurate availability status and optimized delivery routes, thereby ensuring the shortest possible delivery time and reducing transportation costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If items in transit are considered out of stock and unavailable for purchase, then inventory accuracy at physical locations is maintained, but item availability for purchase is reduced and delivery times are extended

Engineering Contradiction:
Improveavailability status accuracyVSAvoiditem availability for purchase
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The system segments inventory into physical fulfillment centers and virtual fulfillment centers (items in transit). This segmentation allows items to be classified into different availability states based on their location, enabling accurate representation of both in-stock and in-transit items as available for purchase while maintaining inventory tracking precision.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A virtual fulfillment center acts as an intermediary concept between physical fulfillment centers and customers. It represents items that are in transit but still available for purchase, serving as a mediator that resolves the contradiction between maintaining inventory accuracy and maximizing item availability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If items in transit are not tracked in real-time, then system complexity is reduced, but delivery time estimation accuracy deteriorates

Engineering Contradiction:
Improvetracking system complexityVSAvoiddelivery time estimation accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The system performs preliminary actions by establishing virtual fulfillment centers and assigning items to them before actual delivery occurs. This preliminary tracking structure enables delivery time estimation without requiring complex real-time physical tracking of every item, as the virtual center serves as a predetermined tracking point.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system creates a virtual copy of the fulfillment center that mirrors the physical location. This virtual fulfillment center tracks items in transit without requiring physical tracking infrastructure, providing accurate delivery time estimates through the virtual representation while minimizing actual tracking system complexity.

Inventive Principle:
Principle #26Copying

3Ease of manufacture

If items are routed through physical fulfillment centers before delivery, then inventory management is simplified, but delivery time and transportation cost increase

Engineering Contradiction:
Improveinventory management simplicityVSAvoiddelivery time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The system introduces dynamic routing that adapts based on item location. Instead of rigidly routing all items through physical fulfillment centers, the system dynamically determines whether items in transit can be delivered directly from their current location, optimizing delivery time while maintaining inventory management through virtual fulfillment center tracking.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs preliminary routing decisions by identifying items that can be delivered directly from their current transit location. This preliminary action avoids unnecessary trips to physical fulfillment centers, reducing delivery time while maintaining inventory management simplicity through the virtual fulfillment center framework.

Inventive Principle:
Principle #10Preliminary action

AI summary

Devices and methods are provided for using virtual fulfillment center locations to facilitate delivery of items. A device may receive a virtual location associated with transportation of an item to a first location. The device may determine a geographic zone associated with the virtual location. The device may determine a first delivery time associated with delivering the item from the first location, and determine a second delivery time associated with delivering the item from the virtual location. The device may receive a purchase request for the item, from a second device, wherein the purchase request is associated with delivery to a second location. The device may determine an estimated delivery date to the delivery location based on the first delivery time or the second delivery time. The device may send, to the second device, an indication of the estimated delivery date.
