Innovation Solution

A vehicle authentication system utilizing Bluetooth Low Energy (BLE) and fingerprint recognition, which includes an AVNT smart interconnection device for BLE authentication and fingerprint identification devices for secure communication and control, allowing keyless entry and starting based on BLE and fingerprint authentication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional vehicle key systems are used, then vehicle security is maintained, but convenience of vehicle use is weakened

Engineering Contradiction:
Improveconvenience of vehicle useVSAvoidvehicle security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The authentication system is segmented into multiple independent modules: Bluetooth Low Energy (BLE) module for contactless authentication, fingerprint recognition module for biometric verification, and RFID module for key-based authentication. Each module operates independently but contributes to the overall authentication process, allowing the system to provide convenience through contactless methods while maintaining security through multiple verification layers

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary authentication actions by detecting the mobile device via BLE before the user physically interacts with the vehicle. The authentication process is initiated automatically when the user approaches the vehicle, and the system prepares authentication credentials in advance, eliminating the need for manual key insertion or button pressing

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If keyless entry systems using radio frequency are used, then convenience is improved, but the system still requires carrying the vehicle key and cannot function without it

Engineering Contradiction:
Improveconvenience of vehicle useVSAvoidauthentication flexibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The authentication system is designed with multi-functionality to support multiple authentication methods: BLE-based mobile device authentication, fingerprint recognition, and traditional RFID key authentication. This universal approach allows users to authenticate using different methods depending on whether they have their mobile device, fingerprint sensor access, or physical key, thereby improving adaptability while maintaining convenience

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system introduces a mobile device as an intermediary authentication medium that carries authentication credentials (such as digital certificates or tokens) between the user and the vehicle. This intermediary enables contactless authentication without requiring the traditional physical key, while the system can fall back to other authentication methods if the intermediary is unavailable

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If biometric technology is applied to vehicles, then security and convenience are improved, but the system is vulnerable to harsh environmental conditions

Engineering Contradiction:
Improveauthentication securityVSAvoidenvironmental sensitivity
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The authentication system segments the authentication process into multiple independent methods (BLE, fingerprint, RFID) rather than relying solely on biometric technology. This segmentation ensures that if environmental conditions affect one authentication method (such as fingerprint recognition in harsh weather), other methods remain available to maintain security without being compromised by environmental factors

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements prior cushioning by providing alternative authentication methods that can compensate for potential failures of the biometric module due to environmental conditions. Before the biometric authentication is attempted, the system is already prepared with fallback options (BLE and RFID authentication), ensuring that security is maintained even if the fingerprint sensor fails due to temperature, moisture, or other environmental factors

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
