Solution Overview

Problem

In-store product returns are inefficient due to long waiting lines at customer service desks and the complexity of existing computer systems, which increase operational costs and reduce customer satisfaction.

Innovation Solution

A mobile-initiated in-store return system using a mobile application that scans product codes to retrieve electronic receipts, applies return rules, and directs customers to a return station for self-service or assisted returns, reducing the need for manual processing and streamlining the return process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If customers bring products to stores for return and use manual processing at customer service desks, then the return process can be completed, but long waiting lines are created and operational costs increase

Engineering Contradiction:
Improvereturn processing speedVSAvoidcustomer waiting time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-validating return eligibility, retrieving electronic receipts, and staging return information before the customer arrives at the store. The return is staged and validated in advance through the mobile application, so when the customer arrives, the process is already prepared and can be completed quickly at the return station.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system enables self-service returns by allowing customers to independently initiate, validate, and track their returns through the mobile application. The return station provides automated scanning and processing, eliminating the need for manual intervention at customer service desks and enabling customers to complete returns on their own timeline.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If a computer system with scanner is used at customer service desks for return processing, then returns can be handled, but system cost and software complexity increase

Engineering Contradiction:
Improvereturn processing convenienceVSAvoidcomputer system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system extracts the return processing functionality from the complex computer system at customer service desks and relocates it to a simplified mobile application on the customer's device. The electronic receipt and return validation are performed on the mobile device, eliminating the need for expensive scanners and complex software systems at the store.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system uses a copy of the return processing logic implemented in the mobile application rather than requiring the full complex system to be present at the store. The mobile application contains a simplified version of the return validation logic that can independently process returns without needing the full computer system infrastructure.

Inventive Principle:
Principle #26Copying

3Reliability

If manual receipt scanning and review is performed at customer service desks, then return validation can be completed, but processing time and operational costs increase

Engineering Contradiction:
Improvereturn validation accuracyVSAvoidreturn processing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system replaces the mechanical manual scanning and review process with automated electronic retrieval and validation. The mobile application automatically retrieves the electronic receipt associated with the product and validates return eligibility through automated rule application, eliminating the need for manual receipt scanning and review by store employees.

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

Solution Approach 2:

The system implements automated feedback loops where the mobile application continuously communicates with the return management system to validate return eligibility, retrieve electronic receipts, and update return status. This automated feedback mechanism ensures accurate validation while significantly reducing processing time compared to manual review processes.

Inventive Principle:
Principle #23Feedback
