Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a central registration system is implemented to manage contactless cards across multiple issuers, then data security and authentication are improved, but system complexity increases

Engineering Contradiction:

Improvedata securityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system is segmented into distinct functional modules: personalization system for card data generation, registration system for card provisioning and status management, and validation system for transaction verification. Each module operates independently with defined interfaces, reducing overall system complexity while maintaining security.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The registration system acts as an intermediary between the personalization system and validation system, centralizing card management functions. This mediator approach simplifies the architecture by providing a single point of control for card registration, status tracking, and validation, rather than requiring direct peer-to-peer communication between all system components.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If unique identifiers and validation systems are implemented for each contactless card, then transaction security is improved, but processing time increases

Engineering Contradiction:

Improvetransaction securityVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Card validation data, including unique identifiers and security credentials, is generated and stored in the validation system during the card personalization and registration phase, before the card is used for transactions. This preliminary preparation allows for rapid validation during actual transactions, as the system already has the necessary security data readily available.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system replaces complex mechanical verification processes with electronic validation of digital identifiers. Instead of physical card verification or manual authentication, the system uses electronic comparison of unique identifiers and validation data stored in databases, significantly reducing processing time while maintaining security.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If replacement card functionality is implemented to link new and old cards, then card management flexibility is improved, but system complexity increases

Engineering Contradiction:

Improvecard management flexibilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The replacement card functionality is implemented by nesting the old card identifier within the new card's validation data structure. When a replacement card is registered, the system stores a reference to the original card's unique identifier in the new card's record, creating a hierarchical relationship that simplifies tracking and management of card replacements without requiring separate complex tracking systems.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

Embodiments cover registering, deregistering, and checking the status of contactless cards. A personalization system creates card data, including identifiers, for new and replacement cards, which are registered or deregistered as needed. A validation system verifies card activity and validity by processing queries with identifiers and encrypted data. Embodiments further include a system that manages contactless card registrations and billing via a card registration database to maintain card data, an API for registration and status updates, and a billing module to calculate charges for issuers.
