Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional EMV cards are used, then basic transaction security is provided, but advanced connectivity and location-specific security features are lacking

Engineering Contradiction:

Improveconnectivity and security featuresVSAvoidtransaction security

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The transaction card integrates multiple functions including EMV chip transactions, wireless communication with mobile devices, location services, and visual alert systems. The card can perform both traditional contact-based transactions and modern contactless transactions, making it universally applicable across different transaction scenarios while enhancing security capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces a mobile device as an intermediary between the transaction card and the external world. The mobile device receives location information from the card, processes security assessments, and communicates with backend systems. This intermediary enables advanced connectivity and location-specific features while maintaining the card's core transaction security functions.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If location-specific security alerts are implemented, then user safety is improved, but device complexity increases

Engineering Contradiction:

Improveuser safetyVSAvoidcard system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The complex location assessment and security alert generation functions are extracted from the card itself and placed in the mobile device and backend systems. The card only performs simple location information retrieval and visual alert display, while the complex processing is done externally. This extraction reduces the card's internal complexity while maintaining user safety features.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system uses the mobile device's existing location services and communication capabilities to provide location-specific security alerts without requiring the card to have its own complex location determination or communication systems. The card leverages the mobile device's existing resources to achieve enhanced security functionality.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If visual indication elements are added to the card, then security alert capability is enhanced, but manufacturing complexity increases

Engineering Contradiction:

Improvesecurity alert capabilityVSAvoidcard manufacturing

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent employs light emitting elements that can change color or illumination states to indicate different security alert conditions. Instead of complex display screens, the system uses color-changing LED indicators that can show multiple security statuses through different colors or lighting patterns, simplifying manufacturing while maintaining versatile alert capability.

Inventive Principle:

Principle #32Color changes
