Solution Overview

Problem

Current motor vehicle hands-free speech units lack standardized methods for connecting and managing multiple Bluetooth-enabled mobile terminals, limiting their functionality and user experience in supporting diverse terminal functions such as audio streaming, data transmission, and SMS download.

Innovation Solution

A motor vehicle system with a wireless interface, storage unit, and control unit that communicates with mobile terminals to identify and manage supported functions, allowing simultaneous connections and automatic activation of corresponding terminal functions, with a display unit providing user-friendly feedback on available and active functions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If standardized Bluetooth commands are used for terminal connection, then compatibility and ease of operation are improved, but functionality and adaptability are limited

Engineering Contradiction:
Improveease of terminal connectionVSAvoidfunctionality support
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system uses standardized Bluetooth commands as a universal interface that can handle multiple terminal functions (telephony, messaging, data transfer, audio streaming) through a single standardized protocol, eliminating the need for proprietary commands for each function while maintaining broad compatibility

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

2Adaptability or versatility

If multiple terminals are connected simultaneously, then adaptability and functionality are improved, but device complexity increases

Engineering Contradiction:
Improvemulti-terminal supportVSAvoidconnection management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system automatically detects available terminal functions through standardized Bluetooth commands, autonomously manages multiple terminal connections, and handles function allocation without requiring complex user configuration or intervention for each connection scenario

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

A single standardized Bluetooth interface handles all terminal functions (telephony, messaging, data, audio) uniformly, allowing multiple terminals to be managed through one universal connection mechanism rather than requiring separate management systems for each function type

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

3Adaptability or versatility

If proprietary Bluetooth commands are used for specific functions, then adaptability is improved, but ease of operation and compatibility deteriorate

Engineering Contradiction:
Improvefunction-specific capabilityVSAvoidoperability complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system implements a universal standardized Bluetooth command set that can perform multiple terminal functions (telephony, messaging, data transfer, audio streaming) through standardized profiles, eliminating the need for proprietary commands while maintaining full functional capability

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

AI summary

A motor vehicle is provided having a wireless interface to a mobile terminal, a storage unit in which information about vehicle functions is stored, and a control unit, which is set up such that information about terminal functions is transmitted from the terminal to the control unit via the wireless interface. The information about vehicle functions is compared to the information about terminal functions, and information about corresponding vehicle functions and terminal functions is stored in the storage unit.
