Solution Overview

Problem

Existing vehicle telematics systems cannot independently communicate with a cellular network or utilize telematics services without relying on a vehicle operator's personal mobile phone, limiting their functionality and service delivery.

Innovation Solution

A method where a vehicle telematics unit detects and pairs with a personal mobile device via Bluetooth, obtains its identifier, and temporarily replaces its own identifier to establish communication with a call center, enabling independent communication and service provision.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the vehicle telematics unit uses its own dedicated identifier for communication, then it can maintain independent identity and service delivery, but it cannot leverage the mobile device identifier to enable seamless handoff and continuity of service

Engineering Contradiction:

Improveservice continuityVSAvoididentifier management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic identifier assignment where the telematics unit can switch between its own dedicated identifier and the mobile device identifier based on operational context. The system dynamically assigns the mobile device identifier when needed for service continuity and falls back to the dedicated identifier for independent operation, resolving the contradiction between service continuity and identifier management complexity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent introduces a mobile device identifier as an intermediary that bridges the telematics unit and the mobile network. This intermediary identifier enables the telematics unit to leverage the mobile device's network presence for seamless service handoff while maintaining its own independent identity through the dedicated identifier, thus resolving the contradiction between dependency and independence.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the vehicle telematics unit relies on the mobile phone for cellular communication, then it can utilize the mobile device's existing cellular connection, but it loses independent communication capability and service delivery

Engineering Contradiction:

Improvecommunication setupVSAvoidindependent communication

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements multi-functionality in the telematics unit by enabling it to operate in multiple communication modes: using the mobile device identifier for leveraged communication when the mobile phone is available, and using its own dedicated identifier for independent communication when the mobile phone is unavailable. This universal approach resolves the contradiction between ease of operation and independent communication capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent changes the communication parameter (identifier) based on operational conditions. When the mobile device is detected, the system changes to using the mobile device identifier for easier setup. When the mobile device is absent, the system changes to using the dedicated identifier for independent operation. This dynamic parameter change resolves the contradiction between ease of operation and independent communication.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If the vehicle telematics unit permanently assigns the mobile device identifier, then it can maintain continuous service delivery, but it cannot restore independent communication when the mobile device is removed

Engineering Contradiction:

Improveservice deliveryVSAvoidcommunication flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements a dynamic identifier assignment mechanism that adapts to the presence or absence of the mobile device. When the mobile device is present, the system dynamically assigns the mobile device identifier for reliable service delivery. When the mobile device is removed, the system dynamically switches to the dedicated identifier to maintain communication flexibility. This dynamic approach resolves the contradiction between reliability and adaptability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent employs feedback mechanisms where the telematics unit continuously monitors the presence of the mobile device and adjusts its identifier assignment accordingly. This feedback loop ensures that the system maintains reliable service delivery when the mobile device is available while preserving the ability to restore independent communication when the mobile device is removed, thus resolving the contradiction between reliability and flexibility.

Inventive Principle:

Principle #23Feedback

AI summary

A method and system of communication between a vehicle telematics unit and a call center via a personal mobile device identifier. The method involves detecting the presence of a personal mobile device at a vehicle, receiving a mobile device identifier from the mobile device, assigning the mobile device identifier to a telematics unit in the vehicle, establishing a data session between the telematics unit and a call center, and sending the mobile device identifier to the call center via the data session.
