Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing shopping browser extensions are only available on desktop web browsers, excluding mobile application users from their benefits during online shopping.

Innovation Solution

A mobile device receives a cryptogram from a contactless card, verifies it, and launches a shopping mobile application or browser extension when the first mobile application is running, enabling functionalities like automatic coupon application and better price search directly within the mobile application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If shopping browser extensions are only available via web browser on desktop, then the extension functionality can be implemented, but mobile application users are excluded from benefiting

Engineering Contradiction:

Improveavailability across platformsVSAvoiduser accessibility

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The shopping extension functionality is made universal by implementing it within a mobile application that can operate on both iOS and Android platforms. The application integrates contactless card reading, coupon searching, and price comparison features into a single mobile-friendly platform, allowing users to access shopping enhancement services regardless of their device type or operating system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If the mobile application launches automatically when contactless card is detected, then user convenience is improved, but security verification may be compromised

Engineering Contradiction:

Improveuser convenienceVSAvoidsecurity verification

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary security verification by first validating the contactless card and verifying the user's identity before automatically launching the shopping extension functionality. This preliminary action ensures that only authenticated users can access the automated features, maintaining security while preserving user convenience.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where the mobile application continuously monitors contactless card detections and provides feedback to the user through notifications or visual indicators. This feedback loop allows users to be aware of automated actions while maintaining control over their data and transactions.

Inventive Principle:

Principle #23Feedback
