Solution Overview

Problem

Existing systems lack driver control over the transmission of personal user data between a mobile phone and a motor vehicle, with existing methods often transmitting data automatically, which can be a concern for privacy.

Innovation Solution

Implementing a dual communication system using Bluetooth for non-driver-specific data exchange and Near-Field Communication (NFC) for driver-specific data transmission, where the driver must consciously initiate the NFC connection by bringing their phone into close proximity with a specific interface, allowing selective data transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If automatic data transmission via Bluetooth is used, then convenience of operation is improved, but driver control over personal data transmission deteriorates

Engineering Contradiction:
Improveconvenience of data transmissionVSAvoiddriver control over data
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent segments data transmission into two distinct types: automatic transmission for non-personal data via Bluetooth, and manual confirmation required for personal user data. This segmentation allows the system to provide convenience for general operations while maintaining driver control over sensitive information, resolving the contradiction between ease of operation and driver control.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If manual confirmation for all data transmission is required, then driver control over personal data is improved, but convenience of operation deteriorates

Engineering Contradiction:
Improvedriver control over dataVSAvoidconvenience of data transmission
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies local quality by differentiating the confirmation requirement based on data type: personal user data requires manual driver confirmation, while non-personal data can be transmitted automatically. This localized approach to control ensures driver authority over sensitive information without creating unnecessary obstacles for routine operations, thus maintaining both control and convenience.

Inventive Principle:
Principle #3Local quality

3Device complexity

If Bluetooth is used for all data exchange, then device complexity is reduced, but security of data transmission deteriorates

Engineering Contradiction:
Improvecommunication system structureVSAvoidprivacy risk
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent segments the communication system into two channels: Bluetooth for non-personal data and a second communication connection for personal user data that requires explicit driver initiation. This segmentation enhances security by ensuring personal data can only be transmitted when the driver consciously activates the process, while maintaining relatively simple device architecture through the use of existing Bluetooth technology for routine communications.

Inventive Principle:
Principle #1Segmentation

AI summary

The invention relates to a method for transmitting data between a mobile telephone (12) and a motor vehicle (1). A first wireless communication connection (14) is automatically established between the mobile telephone (12) and the motor vehicle (1) when a communication interface of the mobile telephone (12) is activated in a corresponding manner, and driver-specific user data (16) is transmitted from the mobile telephone (12) to the motor vehicle (1), at least some of the user data (16) being transmitted to the motor vehicle (1) exclusively via a second communication connection (15) according to the NFC standard.
