Solution Overview

Problem

Current fulfillment centers face inefficiencies in package delivery due to delays in procuring items for orders, leading to customer dissatisfaction and increased costs, as existing systems lack effective communication and urgency handling for customer orders, resulting in suboptimal throughput and resource utilization.

Innovation Solution

A computer-implemented system that generates an order identifier for customer orders, allowing items to be picked and sorted individually without waiting for the entire order, enabling simultaneous shipping of items based on their storage location and delivery route, thereby reducing cycle time and improving worker efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If items are picked and packed individually waiting for the entire order to be complete, then order accuracy is improved, but delivery cycle time increases and productivity decreases

Engineering Contradiction:
Improveorder accuracyVSAvoiddelivery throughput
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent segments the order fulfillment process by creating separate pick waves for different items. Items are grouped into multiple pick waves based on their availability and priority, allowing independent processing of each wave rather than waiting for the complete order. This segmentation enables parallel processing while maintaining order integrity through consolidated packing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary actions by picking and preparing items before the entire order is ready. High-priority or available items are picked in advance and held in temporary storage, allowing the packing process to begin earlier than traditional methods. This preliminary action reduces the overall delivery cycle time while ensuring order accuracy through controlled consolidation.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If the system waits for all items to be available before packing, then packaging accuracy is improved, but packing efficiency and worker productivity deteriorate

Engineering Contradiction:
Improvepackaging accuracyVSAvoidpacking efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The packing process begins in advance by consolidating items that are already picked and ready, rather than waiting for the complete order. The system identifies which items are available and initiates packing for those items while continuing to pick remaining items. This preliminary packing action maintains accuracy through system tracking while significantly improving packing efficiency.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system maintains continuous useful action in the packing process by continuously consolidating items as they become available rather than pausing to wait for the complete order. The packing operation flows continuously, processing items in batches as they are picked, which keeps workers productive while ensuring accurate order fulfillment through systematic consolidation.

Inventive Principle:
Principle #20Continuity of useful action

3Loss of information

If storage spaces are occupied by picked items waiting for order completion, then order tracking is improved, but storage accessibility and picking efficiency worsen

Engineering Contradiction:
Improveorder trackingVSAvoidstorage accessibility
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The system segments storage space usage by creating temporary holding areas for picked items that are separate from the main storage locations. Items are moved to designated consolidation zones after picking, which frees up the original storage spaces for continued picking operations while maintaining order tracking through system records and item identifiers.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces an intermediary consolidation process between picking and final packing. Picked items are transferred to temporary holding zones that act as intermediaries, allowing storage spaces to be released for new picking tasks while items await consolidation. This intermediary step maintains order tracking information while improving storage accessibility and picking efficiency.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Embodiments of the present disclosure is direct to a computer-implemented system for a package delivery. The system may be configured to receive a customer order comprising at least three items; generate an order identifier based on the customer order; associate each item of a plurality of items of the customer order with the order identifier; determine that plurality of items of the plurality of items are associated with a common product identifier and located within a common storage location, the portion corresponding to a number of items; send a first indication to pick the plurality of identical items from the common storage location, and a second indication to pick a different item from another storage location; send indications to sort the first item and second item together without regard to a status of the third item; and send indications to deliver the plurality of identical items in a common container.
