Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If digital credentials are stored on electronic devices for convenient access, then ease of operation is improved, but vulnerability to unauthorized provisioning increases

Engineering Contradiction:

Improveconvenience of digital credential accessVSAvoidsecurity against unauthorized provisioning

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent introduces a secure element as an intermediary component between the NFC controller and the host processor. This secure element acts as a trusted mediator that validates credential data before provisioning, preventing unauthorized credentials from being stored while maintaining convenient digital access. The secure element mediates the interaction between the physical credential and the electronic device's memory systems.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary validation of credential data within the secure element before the credential is actually provisioned to the electronic device. This preliminary action ensures that only authenticated credentials are stored, preventing unauthorized provisioning attempts from succeeding while maintaining the convenience of digital credential storage and access.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If contactless transactions are enabled for faster processing, then productivity is improved, but risk of fraud increases

Engineering Contradiction:

Improvetransaction processing speedVSAvoidfraud risk in contactless transactions

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The secure element serves as a trusted intermediary that validates credential authenticity during contactless transactions. By mediating the transaction process and verifying credentials before authorization, the system enables fast contactless processing while mitigating fraud risk through the secure element's validation capabilities.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces manual verification mechanisms with automated cryptographic validation performed by the secure element during contactless transactions. This substitution maintains the speed advantage of contactless transactions while eliminating the need for manual fraud checking, as the secure element automatically validates credential authenticity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If physical credentials are handed over for verification, then authentication is improved, but risk of unauthorized copying increases

Engineering Contradiction:

Improveauthentication accuracyVSAvoidunauthorized credential copying

Core Design Contradiction:

Measurement precisionVSObject-generated harmful factors

Solution Approach 1:

The secure element acts as a trusted intermediary that receives and validates credential data during the handover process. Instead of directly storing received credentials, the secure element mediates by verifying authenticity through cryptographic validation, preventing unauthorized copying while maintaining accurate authentication.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system applies preliminary anti-action by validating credentials through cryptographic verification before provisioning them to the electronic device. This preemptive validation prevents unauthorized credentials from being stored, countering the potential harm of credential copying before it can occur.

Inventive Principle:

Principle #9Preliminary anti-action
