Solution Overview

Problem

Existing digital wallet systems for mobile transactions lack convenience and security, as they require users to manually select payment cards from multiple wallets and store sensitive information on mobile devices, which can be insecure and inconvenient.

Innovation Solution

A mobile-based remote payment system that allows users to access multiple digital wallets from a single view on their mobile device, using a smart button to select payment options, with secure transaction credentials generated by a payment application or secure hardware, and validated through a central trusted entity, ensuring secure and convenient transactions across multiple merchants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If users manually select payment cards from multiple digital wallets, then users can choose specific payment options, but the operation becomes complex and time-consuming

Engineering Contradiction:

Improvepayment option selectionVSAvoiduser operation complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system automatically identifies and presents relevant payment options to the user based on the current transaction context, eliminating the need for users to manually search through multiple wallets. The payment application self-services by pre-filtering and organizing payment methods, allowing users to simply select from the presented options rather than navigating complex wallet structures.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent introduces a payment application as an intermediary layer between the user's digital wallets and the merchant's payment system. This intermediary automatically manages the complexity of multiple wallets by presenting a simplified selection interface, handling wallet authentication, and coordinating with the merchant server, thereby shielding users from the underlying complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If sensitive payment credentials are stored on mobile devices, then payment transactions can be processed locally, but security risks increase

Engineering Contradiction:

Improvetransaction processing speedVSAvoidpayment security

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent segments the payment system into distinct functional components: the mobile device stores only payment account identifiers and transaction credentials (not full card details), while the merchant server stores and manages the actual sensitive payment credentials. This segmentation allows local transaction initiation for speed while centralizing sensitive data management for security.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The merchant server acts as a secure intermediary that holds and manages sensitive payment credentials. Instead of storing credentials locally on the mobile device, the system uses the merchant server as a trusted intermediary to validate and process payments, thereby improving security while maintaining transaction efficiency through centralized credential verification.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If payment information is entered manually during e-commerce transactions, then transaction security is maintained, but user convenience decreases

Engineering Contradiction:

Improvetransaction securityVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary actions by pre-storing payment account information in digital wallets and pre-configuring payment methods before transactions occur. During the actual transaction, users simply need to select from pre-configured options rather than manually entering all payment details, thereby maintaining security through pre-validated stored information while significantly improving convenience.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses digital copies of payment card information stored in secure wallets. Instead of requiring users to manually re-enter payment details for each transaction, the system creates and uses digital copies of payment information that are securely stored and automatically retrieved, maintaining security through encrypted storage while improving convenience through automatic retrieval and filling.

Inventive Principle:

Principle #26Copying

4Ease of operation

If multiple payment card accounts are stored in a digital wallet, then user convenience is improved, but device security complexity increases

Engineering Contradiction:

Improvepayment access convenienceVSAvoidwallet management complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces a payment application and merchant server as intermediaries that manage the complexity of multiple payment accounts. The mobile device simply stores account identifiers, while the payment application and server handle the complex logic of selecting, validating, and processing the appropriate payment method from multiple accounts, thereby improving user convenience while externalizing the management complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)
