Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The projection of mobile terminal applications onto in-vehicle infotainment terminals results in a full-screen display that affects the use of applications and compromises user experience.

Innovation Solution

An adaptive method for arranging application windows on the in-vehicle infotainment terminal interface, dynamically adjusting their layout based on vacant positions and existing windows to accommodate additional mobile terminal applications, ensuring seamless integration and simultaneous display of both infotainment and mobile applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If mobile terminal applications are projected onto in-vehicle infotainment terminal, then the display content richness is improved, but the user experience deteriorates due to full-screen display affecting application usage

Engineering Contradiction:

Improvedisplay content richnessVSAvoidapplication usage

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The display screen is segmented into multiple independent windows, allowing different applications to be displayed simultaneously in separate regions. This enables users to operate multiple applications at the same time without one full-screen application blocking access to others, thus maintaining display content richness while improving application usability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the display screen are assigned different functions and display characteristics. The screen is divided into multiple window areas where each window can display different application content with appropriate size and position, creating local display quality variations that optimize both information presentation and user interaction

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If multiple application windows are arranged on the driving interface, then the simultaneous display of infotainment and mobile applications is improved, but the device complexity increases

Engineering Contradiction:

Improvesimultaneous display capabilityVSAvoidwindow layout management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The window layout system is designed to be dynamic and adaptive, automatically adjusting window positions, sizes, and arrangements based on the number of active applications and available screen space. This dynamic management reduces the perceived complexity by eliminating manual configuration needs while maintaining versatile simultaneous display capabilities

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system performs self-management of window layouts through automatic arrangement algorithms that detect vacant window positions and dynamically reposition windows without user intervention. This self-service approach handles the complexity of multi-window coordination internally, providing users with simple simultaneous display functionality

Inventive Principle:

Principle #25Self-service

AI summary

A method for displaying a window, performed by an in-vehicle infotainment terminal. The method includes: determining 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 the target window to the driving interface according to the existence condition.
