Solution Overview

Problem

E-commerce platforms face challenges in efficiently managing customer returns, particularly in combining returns from multiple orders into a single transaction, which can be cumbersome and lacks integration with purchase functionality.

Innovation Solution

An electronic marketplace system is configured to support a 'return cart' that allows users to combine items from different transactions, process them as a single transaction, and provide a persistent interface for accessing and managing returns, purchases, and exchanges, enabling combined return and purchase functionalities within a single transaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users manage returns from multiple orders separately, then each return can be processed individually with clear tracking, but the overall return process becomes cumbersome and time-consuming

Engineering Contradiction:
Improvereturn process simplicityVSAvoidtime to manage returns
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent combines multiple returns from different orders into a single return cart, allowing users to select items from various orders and process them together. This merging approach reduces the number of separate return transactions needed, simplifying the overall return process and reducing time expenditure while maintaining individual item tracking through the unified return cart interface.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If the return cart is cleared after each use, then the system maintains data freshness and avoids confusion, but users must repeatedly re-select items losing their place in the return process

Engineering Contradiction:
Improvedata accuracyVSAvoidtime to re-select items
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements a persistent return cart that preserves user selections across multiple browsing sessions and device logins. The system pre-loads the return cart with previously selected items, allowing users to continue their return process without re-selecting items. This preliminary action of saving and restoring cart state eliminates redundant user actions while maintaining data integrity through server-side persistence.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the return cart is persistent and associated with user accounts, then users can access it from different devices and times, but the system complexity increases

Engineering Contradiction:
Improveaccess flexibilityVSAvoidsystem architecture complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a server-side return cart database as an intermediary between the user interface and the return processing system. This mediator stores return cart data associated with user accounts, enabling cross-device and cross-session access without requiring complex client-side synchronization. The server acts as a central repository that simplifies the overall system architecture while providing persistent, adaptable access to return carts.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An electronic marketplace, or other website, may be configured to support customer returns using a “return cart,” allowing a user to combine items, purchased in different transactions, in a single return. In some cases, the user may be able to browse a purchase history including several different orders, and select items from different orders to add to the return cart. The electronic marketplace may process the combined returns as a single transaction and provide an identifier that is common to all the items in the combined return, such as a return number, a shipping number/label, etc. In some examples, the return cart may be persistent and/or associated with a user account, thereby allowing it to be accessible at different times and/or from different devices. A return cart may also be combined with a “shopping cart,” which allows the customer to purchase, exchange and/or return items in a single transaction.
