Solution Overview

Problem

Current drop shipping systems lack efficient state management and communication protocols, leading to issues with order processing and inventory management, particularly in scenarios where intermediaries handle orders and shipments without direct possession of inventory.

Innovation Solution

A system and method for order processing state management that utilizes a network of components including order creation, outbound messaging, and post-order processing components to manage purchase orders, item data, and message data objects, ensuring effective failover resiliency, item-level visibility, and flexible communication protocols, such as cXML, to facilitate seamless order fulfillment and notification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional drop shipping systems are used without item-level granularity, then system complexity is reduced, but order processing efficiency and inventory management accuracy deteriorate

Engineering Contradiction:
Improveorder processing efficiencyVSAvoiddata model complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the order data model into multiple hierarchical levels: order-level data objects (representing the complete order), item-level data objects (representing individual line items), and message-level data objects (representing communication protocols). This segmentation enables granular tracking and management of each component, improving order processing efficiency while maintaining manageable system complexity through structured organization.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If state management is not implemented at item-level, then system simplicity is maintained, but tracking accuracy and visibility of individual items deteriorate

Engineering Contradiction:
Improveitem tracking accuracyVSAvoidstate management complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces a new dimensional layer of state management by implementing separate state tracking at the item level within the data model. Each item data object maintains its own state information independently, enabling precise tracking of individual item status (ordered, shipped, delivered, etc.) without requiring complex aggregate-level state management. This dimensional approach to state tracking enhances measurement precision while keeping the system architecture manageable.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If flexible communication protocols like cXML are implemented, then communication versatility between vendors and distributors is improved, but system complexity and integration difficulty increase

Engineering Contradiction:
Improvecommunication protocol flexibilityVSAvoidsystem integration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal messaging layer using cXML protocol that can handle multiple communication scenarios (order placement, order status updates, inventory inquiries, shipping notifications) through a single standardized interface. The message data objects are designed to be protocol-agnostic yet flexible enough to support various communication needs, enabling the system to interact with different vendors and distributors using a common language, thereby improving versatility while managing integration complexity through standardization.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Various embodiments of a system and method for an order handling data model with item-level granularity are described. Embodiments may include an order handling system configured to, for a given purchase order received from an ordering entity, generate within a data store a purchase order data object, item data objects for items of the purchase order, and message data objects for messages associated with item data objects. In various embodiments, the order handling system may also generate in the data store mapping information for mapping each of the different data objects for a given purchase order together. The order handling system may also provide to the ordering entity a notification for a particular item. The notification may be based on information accessed from the item data object corresponding to the particular item or information accessed from other data objects associated with that item data object according to the mapping information.
