Solution Overview

Problem

The existing methods for accessing motor vehicles using mobile communication devices, such as smartphones, require a pairing mechanism that is restrictive and burdensome, especially in scenarios where multiple vehicles are available, as users must identify and enter specific pairing codes for each vehicle, which can be time-consuming and inconvenient.

Innovation Solution

A method that eliminates the need for a pairing mechanism by transmitting unique authentication frames from vehicles in advertising mode, using a remote server to generate and store accreditation codes on the smartphone, allowing secure recognition and authorization without manual code entry, leveraging Bluetooth Low Energy (BLE) protocol for communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a pairing mechanism is implemented for vehicle access, then security of data exchange is improved, but ease of operation deteriorates due to manual code entry requirements

Engineering Contradiction:
Improvesecurity of data exchangeVSAvoidease of vehicle access
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary pairing actions during vehicle rental or authorization phases. The pairing code is pre-configured and stored in the smartphone's secure element before the user needs to access the vehicle. When the user approaches the vehicle, authentication occurs automatically using this pre-established pairing, eliminating the need for manual code entry at the moment of access while maintaining security.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The smartphone automatically performs authentication with the vehicle using pre-stored pairing information and identification keys. The system enables self-service access where the user simply needs to have the smartphone with them - no manual pairing code entry is required. The authentication process occurs automatically through the exchange of identification data between the smartphone and vehicle electronic module.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If multiple vehicles are available for selection, then adaptability is improved, but device complexity increases due to vehicle identification requirements

Engineering Contradiction:
Improveability to access multiple vehiclesVSAvoidcomplexity of vehicle identification
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system uses unique identification keys and advertising data specific to each vehicle. Each vehicle transmits its own identification information through BLE advertising packets, and the smartphone contains vehicle-specific authentication credentials. This allows the system to handle multiple vehicles with different identification characteristics without requiring a complex centralized management system - each vehicle-smartphone pair has its own localized authentication credentials.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system performs preliminary configuration during the vehicle rental or authorization process. The smartphone is pre-configured with the specific identification key and authentication credentials for the authorized vehicle before the user needs to access it. This eliminates the need for real-time vehicle selection and identification complexity - the system already knows which vehicle the user is authorized to access.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If pairing code entry is required, then security is improved, but loss of time increases due to manual authentication steps

Engineering Contradiction:
Improvesecurity of authenticationVSAvoidtime for authentication
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The pairing code and authentication credentials are pre-configured in the smartphone's secure element during vehicle rental or authorization. The user does not need to manually enter codes at the moment of access - the authentication data is already stored and ready to be used. This eliminates the time-consuming manual entry step while maintaining the security of the authentication process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system skips the manual pairing code entry step by using pre-configured authentication credentials. The smartphone automatically exchanges identification data with the vehicle through BLE advertising and connection processes, rushing through the authentication sequence without requiring user interaction for code entry. This maintains security through cryptographic authentication while dramatically reducing the time required for vehicle access.

Inventive Principle:
Principle #21Skipping (Rushing through)
