Solution Overview

Problem

Consumers often refrain from returning defective or unwanted grocery items due to the time and effort required for in-store returns, leading to customer dissatisfaction and loss for the store, highlighting the need for automated refund processing systems that allow online refunds without physical return requirements.

Innovation Solution

A system comprising a return management system, order management system, payment system, and databases that enable users to initiate and process refund requests online, utilizing a machine learning model to determine returnability based on rules and policies, and perform cost-benefit analyses to facilitate refunds for eligible items.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If consumers return products through traditional in-store methods, then the store can verify and process returns, but consumers experience significant time loss and effort

Engineering Contradiction:
Improveease of return processVSAvoidtime for in-store return
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system enables consumers to self-initiate refund requests through a mobile device interface, automatically providing instructions for returning items to designated locations such as lockers or drop-off points, eliminating the need for customer service interaction and significantly reducing time loss

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system pre-provides return instructions and designates return locations before the consumer actually returns the item, allowing consumers to plan their return route and avoid waiting in lines at customer service desks, thereby reducing time loss and improving ease of operation

Inventive Principle:
Principle #10Preliminary action

2Loss of time

If consumers abandon return requests due to high effort, then consumer time is saved, but store losses increase

Engineering Contradiction:
Improveconsumer timeVSAvoidstore loss
Core Design Contradiction:
Loss of timeVSLoss of energy

Solution Approach 1:

By enabling automated self-service refund initiation, the system captures returns that would otherwise be abandoned, preventing store losses while keeping consumer time investment minimal through automated instructions and designated drop-off points

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system provides real-time feedback to consumers about their refund request status and return instructions, increasing consumer confidence and completion rates, thereby reducing abandoned returns and associated store losses without requiring additional consumer time

Inventive Principle:
Principle #23Feedback

3Ease of operation

If the system allows online refunds without return requirements, then consumer convenience improves, but fraudulent activities increase

Engineering Contradiction:
Improveonline refund convenienceVSAvoidfraudulent activity
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system introduces an intermediary verification layer that uses machine learning models to assess returnability based on multiple factors including item category, purchase history, and return reasons, automatically approving legitimate refunds while blocking fraudulent ones, thus maintaining consumer convenience while preventing fraud

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system dynamically adjusts returnability parameters and thresholds based on learned patterns from historical data, adapting to new fraud techniques while maintaining high approval rates for legitimate requests, balancing convenience and fraud prevention

Inventive Principle:
Principle #35Parameter changes

4Productivity

If the system processes all refund requests automatically, then processing speed increases, but accuracy of returnability determination decreases

Engineering Contradiction:
Improverefund processing speedVSAvoidreturnability determination accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system employs machine learning models as intermediaries that automatically analyze multiple data points including item characteristics, purchase patterns, and return reasons to determine returnability with high accuracy, enabling automated processing without sacrificing precision

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces manual customer service review with automated machine learning-based determination, significantly increasing processing speed while maintaining or improving accuracy through consistent application of returnability criteria across all requests

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A system can include one or more processors and non-transitory computer-readable media storing computing instructions configured to run on the one or more processors and perform a method for automatically processing an online return request. The method performed by the system can receive a refund request from a user computer used by a customer of a grocery store, the refund request for returning a grocery item (a) previously purchased as part of a transaction of the grocery store and (b) paid for by a payment method via the transaction; and process a refund solution based on the transaction and the grocery item. In this system, the method can process the refund solution by determining a returnable status of the grocery item according to one or more returnability rules dynamically generated by a machine learning model. If the returnable status of the grocery item is negative, the method performed by this system can deny the return request. If the returnable status of the grocery item is not negative, the method performed by this system can then proceed with generating a cost-benefit analysis result based on one or more cost-benefit factors associated with the grocery item. If the cost-benefit analysis result is negative, the method performed by this system can process the refund request by returning a return amount to the customer for the grocery item; otherwise, the method can provide to the user computer an authorization for return of the grocery item to a physical location of the grocery store in order for the customer to receive the return amount for the refund request. Other embodiments are disclosed.
