Solution Overview

Problem

Existing fulfillment centers face inefficiencies due to underutilization during periods of reduced demand, and the need to ship multiple items from different sources separately, leading to delayed and costly deliveries.

Innovation Solution

Implementing a delivery system that utilizes unmanned aerial vehicles (drones) to transport items between fulfillment centers, where they are combined with other items in a carrier vehicle and delivered to customers via autonomous ground vehicles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If fulfillment centers are sized to accommodate peak demand, then they can handle maximum receiving, storing and distribution flows, but they are underutilized during times of reduced demand

Engineering Contradiction:

Improvefulfillment capacityVSAvoidunderutilization

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The system dynamically adjusts fulfillment operations by enabling items to be sourced from multiple distributed locations rather than relying on a single static fulfillment center. This allows the network to flexibly allocate resources based on real-time demand, ensuring that fulfillment capacity is optimized during peak periods while avoiding underutilization during off-peak times.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent segments the fulfillment function across multiple distributed sources rather than consolidating all items in one large fulfillment center. This segmentation allows each source to be optimally sized for its local demand, eliminating the need for any single facility to be oversized for peak demand while maintaining overall system capacity.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If items are shipped separately from different sources, then each item can be delivered from its location, but the items arrive at different times and at greater costs

Engineering Contradiction:

Improveorder fulfillmentVSAvoiddelivery time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary actions by identifying items that can be combined and routing them through a coordinated multi-modal delivery process. Items are prepared for consolidation at intermediate points, and the system pre-coordinates the timing and routing of different items to ensure they arrive together, rather than allowing them to ship independently.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces intermediary fulfillment centers and multi-modal transport systems that act as mediators between item sources and final destinations. These intermediaries consolidate items from different sources and coordinate their delivery, ensuring synchronized arrival times while optimizing the overall delivery route and mode.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If items are shipped separately from different sources, then each item can be delivered from its location, but shipping costs increase

Engineering Contradiction:

Improveorder fulfillmentVSAvoidshipping cost

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The system merges multiple item shipments into a coordinated delivery process. By consolidating items from different sources into unified delivery routes and using multi-modal transport efficiently, the system reduces redundant shipping costs while maintaining the ability to fulfill orders from distributed locations.

Inventive Principle:

Principle #5Merging (Combining)

4Productivity

If a single fulfillment center is used, then all items must be available at one location, but it frequently does not include all items requested by customers

Engineering Contradiction:

Improveorder fulfillment rateVSAvoidfulfillment center size

Core Design Contradiction:

ProductivityVSArea of stationary object

Solution Approach 1:

The patent segments the fulfillment function across multiple distributed sources, allowing each source to specialize in specific items or product categories. This eliminates the need for any single fulfillment center to stock all possible items, while the coordinated multi-source system ensures complete order fulfillment by aggregating items from multiple locations.

Inventive Principle:

Principle #1Segmentation

AI summary

When a customer places an order for a first item and a second item, delivery systems utilize an aerial vehicle to transport the first item from a first source of the first item to a second source of the second item. At the second source, the first item and the second item are transferred into a carrier vehicle and transported toward a destination of the order. Once the carrier vehicle arrives within a vicinity of the destination, an autonomous ground vehicle departs the carrier vehicle with the first item and the second item, and delivers the first item and the second item to the destination. The delivery systems effectively expand the capacity of sources of items, and simplify processes for delivering orders for items, by enabling items from multiple sources to be combined at a single source prior to delivery, and transported to a destination from the single source.
