Solution Overview

Problem

The transition between mobile device operations and an in-vehicle information system is not seamless, often interrupting currently executing functions, requiring users to navigate different user interfaces and lose their application context, which increases processing resource consumption and user attention.

Innovation Solution

The system and methods for integrating mobile device operations with an in-vehicle information system allow the context of mobile device applications to be persisted and restored, enabling seamless transitions by managing application states and user interface views between devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If mobile device operations are integrated with in-vehicle information system, then functionality is expanded, but application context is lost and user interface continuity is interrupted

Engineering Contradiction:

Improvefunctionality expansionVSAvoidapplication context loss

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system performs preliminary actions by detecting the state of applications on the mobile device before disconnecting, storing this state information in advance. This allows the in-vehicle information system to restore the application context seamlessly after connection, preventing information loss while maintaining expanded functionality.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary mechanism that mediates between the mobile device and in-vehicle information system. This intermediary stores and transfers application state information, ensuring that context is preserved during the transition between devices while still enabling functionality expansion through integration.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If mobile device operations are integrated with in-vehicle information system, then functionality is expanded, but user interface continuity is interrupted

Engineering Contradiction:

Improvefunctionality expansionVSAvoiduser interface continuity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system detects and stores the user interface state (such as active application, display content, and interaction context) before disconnection occurs. This preliminary capture of UI state enables the in-vehicle information system to restore continuity seamlessly, maintaining ease of operation while expanding functionality through integration.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

An intermediary component facilitates the transfer of user interface state information between the mobile device and in-vehicle information system. This mediator ensures that UI continuity is preserved during device transitions, allowing users to maintain their interaction context while accessing expanded functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Use of energy by moving object

If application context is not persisted during device transition, then processing resources are saved, but user interaction time increases

Engineering Contradiction:

Improveprocessing resource consumptionVSAvoiduser interaction time

Core Design Contradiction:

Use of energy by moving objectVSLoss of time

Solution Approach 1:

The system performs preliminary detection and storage of application states at the moment of disconnection, which is a minimal processing task compared to full application restoration. This preliminary action consumes minimal processing resources while enabling rapid context restoration, thereby reducing user interaction time without significant energy expenditure.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements a selective approach where only essential application state information is stored and recovered, rather than maintaining full application contexts. This discarding of non-essential data reduces processing resource consumption while the recovery of critical state information minimizes user interaction time during transitions.

Inventive Principle:

Principle #34Discarding and recovering

AI summary

A method at an electronic device, comprising: providing, to an in-vehicle information system, access to operational condition data of the electronic device while the electronic device is linked to the in-vehicle information system, the in-vehicle information system providing user interface access to the electronic device on a display screen of the in-vehicle information system; determining that the operational condition data satisfies predetermined criteria; and in response to determining that the operational condition data satisfies the predetermined criteria, sending an instruction to the in-vehicle information system for displaying a status indicator associated with the operational condition data on an user interface of the in-vehicle information system.
