Innovation Solution

A system and method for a vehicle device to identify a wireless authorized network, establish a secure connection, and initiate an authorized transaction, which is validated and severed upon completion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a secure connection is established between vehicle device and wireless authorized network, then transaction security and fraud prevention are improved, but connection establishment time and system complexity increase

Engineering Contradiction:

Improvetransaction securityVSAvoidconnection establishment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-establishing trust relationships between vehicle devices and authorized networks before transactions occur. The vehicle device is pre-configured with authorized network identifiers and credentials, allowing rapid reconnection without full authentication handshakes, thus reducing connection establishment time while maintaining security

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses digital certificates and cryptographic keys as copies of trust relationships. Instead of verifying physical identities or performing complex mutual authentication each time, the system exchanges and verifies digital copies (certificates) that represent authorized relationships, enabling fast secure connection establishment

Inventive Principle:

Principle #26Copying

2Ease of operation

If physical interaction is minimized for transaction convenience, then ease of operation is improved, but transaction validation and fraud oversight may be compromised

Engineering Contradiction:

Improvetransaction convenienceVSAvoidtransaction validation

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system replaces mechanical/physical interaction (manual signing, physical token exchange, face-to-face verification) with electronic/cryptographic mechanisms. Digital signatures, cryptographic protocol exchanges, and automated authentication replace physical actions, enabling contactless transactions that maintain or enhance validation reliability through cryptographic proof

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system introduces cryptographic protocols and digital certificates as intermediaries between transaction parties. These intermediaries carry validated information (digital signatures, authentication tokens) that prove transaction legitimacy without requiring direct physical interaction or trust between parties, thus enabling convenience without compromising validation

Inventive Principle:

Principle #24Intermediary (Mediator)
