Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If self-checkout units are used to improve shopping speed and convenience, then customer service efficiency is improved, but the ability to offer credit applications and accept credit payments is lost

Engineering Contradiction:

Improveshopping speedVSAvoidpayment option availability

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The self-checkout unit is enhanced with a display device and communication interface, enabling it to perform multiple functions: traditional scanning and payment processing, plus credit application presentation and submission. This allows the same device to serve both efficiency and versatility needs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The display device acts as an intermediary between the self-checkout system and the customer, presenting credit application information and receiving customer responses. This mediator enables credit functionality without requiring traditional cashier staff.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If traditional cashier staffed registers are used to provide credit applications, then payment flexibility is improved, but service speed and convenience are reduced

Engineering Contradiction:

Improvepayment option availabilityVSAvoidservice speed

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The system enables customers to complete credit applications themselves at the self-checkout unit. The display device presents application information and the customer can submit responses directly, eliminating the need for cashier assistance while maintaining payment flexibility.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If credit application processes are simplified for quick approval, then customer convenience is improved, but application completeness and risk assessment may be compromised

Engineering Contradiction:

Improveapplication easeVSAvoidcredit assessment accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system pre-presents complete application information and required responses on the display device before the customer submits the application. This ensures all necessary data is collected upfront, maintaining assessment accuracy while enabling self-service speed.

Inventive Principle:

Principle #10Preliminary action

AI summary

A method performed by at least one computing device. The method includes receiving a credit request from a self-checkout device before a customer completes an instore checkout process and sending a request for a Uniform Resource Locator (“URL”) to one or more authentication computing devices. The authentication computing device(s) send the URL to the mobile device. The method includes sending a credit application to the mobile device after the customer selects the URL, receiving a submission of the credit application from the mobile device, approving credit based on the submission, and forwarding a code to the mobile device. The code indicates that the credit is to be used to complete the instore checkout process when scanned by the scanner.
