Solution Overview

Problem

Existing methods for projecting mobile terminal applications onto in-vehicle infotainment terminals result in poor user experience due to full-screen display affecting the use of in-vehicle infotainment applications and lack of efficient window management for multiple applications.

Innovation Solution

An adaptive window management system for in-vehicle infotainment terminals that dynamically adjusts the layout based on vacant positions and application window numbers, allowing seamless addition and removal of mobile terminal application windows while maintaining efficient use of the driving interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If mobile terminal applications are projected onto in-vehicle infotainment terminal using full-screen display, then the display content richness is improved, but the user experience deteriorates due to inability to use in-vehicle infotainment applications simultaneously

Engineering Contradiction:
Improvedisplay content richnessVSAvoiduser experience
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The display interface is segmented into multiple windows, allowing the mobile terminal application window and in-vehicle infotainment application windows to coexist on the same screen. This segmentation enables users to access both mobile applications (such as navigation and music) and vehicle functions simultaneously, resolving the contradiction between display content richness and ease of operation.

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If multiple application windows are arranged in the driving interface, then the display content richness is improved, but the device complexity increases due to lack of efficient window management

Engineering Contradiction:
Improvedisplay content richnessVSAvoidwindow management complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The window management system dynamically adjusts window layouts based on the number of open applications. When applications are added or removed, the system automatically reconfigures the window arrangement and updates the window queue, maintaining efficient management without requiring complex manual intervention. This dynamic adaptation reduces management complexity while supporting multiple concurrent applications.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements feedback mechanisms where the window queue state is continuously monitored and used to drive layout adjustments. When the set of open applications changes, the system receives feedback about the current window configuration and automatically makes necessary adjustments to maintain optimal display arrangement, simplifying the overall management process.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If window layout is dynamically adjusted based on vacant positions, then the ease of operation is improved, but the device complexity increases due to adaptive layout management

Engineering Contradiction:
Improveconvenience of useVSAvoidlayout management complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The window management system operates autonomously by detecting vacant window positions and automatically arranging new windows in appropriate locations. The system monitors the window queue and performs self-adjustment when applications are added or removed, eliminating the need for complex manual layout management while improving convenience of use.

Inventive Principle:
Principle #25Self-service

AI summary

The invention relates to a method and apparatus for displaying a window, a medium and an in-vehicle infotainment terminal. The method is performed by an in-vehicle infotainment terminal. The method includes: determining (5101) an existence condition of a vacant window position in a driving interface in response to receiving a window addition instruction for a target window, where the target window is configured to display an application interface of a mobile terminal application or a mirror image of a mobile terminal; and adding (S102) the target window to the driving interface according to the existence condition.
