Solution Overview

Problem

Users face challenges in setting up wireless communication links between their mobile devices and vehicle systems, particularly infotainment systems, as existing methods are cumbersome and not easily automated.

Innovation Solution

A device equipped with radio means, time measuring capabilities, and GPS sensors automatically detects and prioritizes mobile devices based on time spent within range and frequency of presence to establish a wireless communication link, such as Bluetooth or WLAN, optimizing the connection process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If automatic selection of mobile devices is implemented, then ease of operation is improved, but device complexity increases

Engineering Contradiction:

Improveease of wireless connection setupVSAvoidcomplexity of connection management system

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by continuously monitoring and storing information about mobile devices in the vicinity before a connection is requested. It maintains a database of devices with their presence duration and frequency data, so when connection setup is needed, the selection is already prepared based on pre-analyzed usage patterns.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The connection system serves itself by automatically selecting mobile devices based on predefined criteria (presence duration, frequency) without requiring user intervention. The system autonomously evaluates candidates and establishes connections, making the process self-sufficient and eliminating manual configuration steps.

Inventive Principle:

Principle #25Self-service

2Reliability

If multiple mobile devices are monitored and evaluated, then reliability of connection selection is improved, but loss of time in processing increases

Engineering Contradiction:

Improvereliability of device selectionVSAvoidtime for connection setup

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system continuously monitors and pre-evaluates mobile devices in the background, maintaining updated information about their presence and usage patterns. This preliminary data collection and analysis occurs asynchronously, so when connection setup is triggered, the evaluation is already complete or can be quickly finalized.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The monitoring and evaluation process runs continuously in the background without interrupting normal vehicle operations. Multiple devices are tracked simultaneously over time, accumulating usage data that informs future connection decisions, ensuring reliable selection without adding noticeable delay to the connection process.

Inventive Principle:

Principle #20Continuity of useful action
