Solution Overview

Problem

Vehicle display devices have varying sizes and hardware limitations, making it difficult for web pages designed for smartphones and PCs to be properly displayed and used, necessitating a method to determine compatibility and usability.

Innovation Solution

A compatibility-determining server generates a render tree for specific web content and uses predefined verifying scenarios to assess compatibility with vehicle display devices, including checks for event handlers, media queries, text sizes, and advertisement compatibility, to determine if web pages can be displayed effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If web pages are designed for smartphones and general PCs, then they can be easily used through those devices, but they may not be displayed properly on vehicle display devices due to hardware limitations and varying sizes

Engineering Contradiction:

Improveease of use on smartphones and PCsVSAvoidcompatibility with vehicle display devices

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary compatibility verification by generating a render tree and executing verifying scenarios before actual display on the vehicle display device. This advance checking identifies potential display issues with event handlers, media queries, text sizes, and other web components, allowing the system to determine compatibility in advance and prevent improper display on vehicle devices with varying hardware specifications

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system changes verification parameters by creating multiple verifying scenarios that test different aspects of web page compatibility. Each scenario checks specific parameters such as event handler compatibility, media query responsiveness, text size appropriateness, and advertisement display suitability, allowing comprehensive adaptation assessment across different vehicle display device specifications

Inventive Principle:

Principle #35Parameter changes

2Speed

If web pages are displayed on vehicle display devices without compatibility verification, then display speed is maintained, but display quality and user experience deteriorate due to improper rendering and difficult usability

Engineering Contradiction:

Improvedisplay speedVSAvoiddisplay quality and rendering accuracy

Core Design Contradiction:

SpeedVSManufacturing precision

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides self-service compatibility verification where the web content itself is tested against the vehicle display device specifications through automated rendering and scenario execution. The render tree generation and verifying scenarios allow the web page to self-verify its compatibility without manual intervention, ensuring both speed and quality

Inventive Principle:

Principle #25Self-service

3Measurement precision

If comprehensive compatibility verification is performed including multiple verifying scenarios, then compatibility determination accuracy is improved, but system complexity increases

Engineering Contradiction:

Improvecompatibility determination accuracyVSAvoidverification system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The verification system is segmented into distinct verifying scenarios, each focusing on specific compatibility aspects such as event handlers, media queries, text sizes, and advertisements. This segmentation allows comprehensive verification to be broken down into manageable, independent modules that can be executed systematically, improving accuracy while maintaining system organization and reducing perceived complexity

Inventive Principle:

Principle #1Segmentation

4Reliability

If multiple verifying scenarios are executed to check different components, then compatibility assessment thoroughness is improved, but processing time increases

Engineering Contradiction:

Improvecompatibility assessment thoroughnessVSAvoidverification processing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The verifying scenarios are executed in a continuous automated sequence without manual intervention. The render tree generation flows continuously into scenario execution, with each verification step immediately following the previous one, maintaining continuous useful action throughout the verification process to minimize idle time while ensuring thorough assessment

Inventive Principle:

Principle #20Continuity of useful action

AI summary

A method determines a degree of compatibility of a web content with a vehicle display device. The method includes steps of: (a) the compatibility-determining server generating a specific render tree by referring to specific web content information; (b) the compatibility-determining server determining whether the specific web page is compatible with the vehicle display device according to a verifying scenario, wherein the verifying scenario is configured as a predetermined program by referring to at least part of (i) at least one first component included in the specific render tree and (ii) at least one second component included in the specific specification information; and (c) in response to determining that the specific web page is compatible, the compatibility-determining server performing or supporting another device to perform a process of displaying the specific web page on a display of the vehicle display device.
