Solution Overview

Problem

Existing return systems in the retail industry struggle with inefficiencies in processing returns due to delayed fraud detection, leading to poor customer satisfaction and increased operational costs, as they cannot immediately accept or reject returns based on real-time risk assessment.

Innovation Solution

An automated kiosk equipped with an imaging device, network interface, and machine learning model predicts the risk score of a return item in real-time, allowing immediate acceptance or rejection and refund processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional return systems use strict return policies to detect fraud, then fraudulent return loss is reduced, but customer satisfaction deteriorates due to delayed refund processing

Engineering Contradiction:
Improvefraud detection accuracyVSAvoidrefund processing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary risk assessment by analyzing historical return data, customer profiles, and item information before the actual return transaction. This pre-computed risk scoring enables immediate decision-making at the point of return, eliminating delays while maintaining fraud detection accuracy

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces manual inspection and human decision-making with an automated machine learning model that processes return requests in real-time. This substitution of mechanical/electronic automation for human processes enables instantaneous risk assessment and refund processing without sacrificing detection reliability

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

2Measurement precision

If manual inspection processes are used to assess return risk, then fraud detection accuracy is improved, but processing efficiency deteriorates

Engineering Contradiction:
Improverisk assessment accuracyVSAvoidreturn processing speed
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The system replaces manual inspection processes with an automated machine learning model that analyzes multiple data dimensions simultaneously. This electronic automation maintains or improves assessment accuracy through comprehensive data analysis while increasing processing speed by eliminating human workflow bottlenecks

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

Solution Approach 2:

The system creates and analyzes digital copies of return requests, customer profiles, and historical data through the machine learning model. This virtual replication and analysis of data enables rapid risk assessment without physical handling or manual review, maintaining precision while dramatically improving processing speed

Inventive Principle:
Principle #26Copying

AI summary

Disclosed embodiments provide systems and methods related to collecting return items using an automated kiosk based on a real time risk decision. The automated kiosk captures return item information representing a return item and transmits the return item information and a request for return risk level relating to the return item to a server operable to execute a machine learning model trained on historical information to determine the risk level. The server determines the risk level based on the received return by using the machine learning model and transmits the determined risk level to the kiosk in real-time. Based on the determined risk level and a return amount associated with the return item, the server may also process a refund in real-time.
