Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users with smart cards are limited in their ability to manage and update settings due to the need for physical access to smart card-accepting devices, restricting their flexibility in changing settings or conducting transactions.

Innovation Solution

A system that enables smart card management through a mobile device application using near-field communications (NFC), allowing users to update personal identification numbers (PINs) and authenticate transactions via a mobile application associated with a financial institution, which communicates with the smart card and authorizes transactions through a network.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users rely on physical smart card-accepting devices to manage smart card settings, then security is maintained through controlled access, but user flexibility and convenience are reduced due to location limitations

Engineering Contradiction:

ImproveUser flexibility in managing smart card settingsVSAvoidLocation independence for smart card management

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent introduces a mobile device as an intermediary between the user and the smart card management system. The mobile device application communicates with the issuer system over a network, enabling users to manage smart card settings remotely without needing physical access to traditional smart card-accepting devices. This intermediary approach resolves the contradiction by providing location independence while maintaining security through the trusted mobile device.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If users can remotely manage smart card settings via mobile device, then user convenience and flexibility are improved, but system complexity increases due to additional communication protocols and security validation requirements

Engineering Contradiction:

ImproveRemote smart card management capabilityVSAvoidSystem architecture complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The mobile device application serves multiple functions: it acts as a smart card reader through NFC, communicates with the issuer system over a network, validates trust relationships, and manages smart card settings. By consolidating these functions into a single multi-functional mobile application, the system reduces overall complexity compared to requiring separate dedicated devices for each function, while still enabling remote smart card management.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If the system implements trusted device validation and PIN verification through mobile application, then transaction security is enhanced, but operation time increases due to additional authentication steps

Engineering Contradiction:

ImproveTransaction securityVSAvoidAuthentication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs trusted device validation and establishes security relationships in advance, during the device registration phase. Once the mobile device is validated and trusted status is established, subsequent transactions can proceed more quickly without repeating the full validation process. This preliminary action reduces authentication time for ongoing transactions while maintaining security.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces traditional mechanical PIN verification at physical terminals with electronic biometric authentication (fingerprint, facial recognition) through the mobile device. This substitution maintains security while significantly reducing authentication time, as biometric verification is faster than manual PIN entry and validation processes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
