Vehicle Infotainment Browser Synchronization via Web Server Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infotainment systems in vehicles lack the ability to synchronize data content across multiple browser instances, preventing coordinated display of information between front and rear area displays.
Innovation Solution
Implementing a web server on the computing system with sockets for communication between browser instances, using a defined communication protocol to mediate data exchange and synchronize displays, allowing for synchronized data content across different displays in the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple browser instances are provided independently on the computer system, then each browser instance can operate autonomously, but the browser instances cannot synchronize data content between displays
Solution Approach 1:
A web server is introduced as an intermediary component between multiple browser instances. The web server receives data from one browser instance and distributes it to other browser instances, enabling synchronization without compromising individual browser autonomy. This mediator approach allows independent operation while achieving data consistency across displays.
2Loss of information
If a web server is implemented for data communication between browser instances, then synchronized data content can be displayed across multiple displays, but the device complexity increases
Solution Approach 1:
The web server is designed to serve multiple functions: it acts as a communication hub for data synchronization, supports various browser instances simultaneously, and enables different types of data exchange (real-time updates, request-response communication). This multi-functionality reduces the need for separate specialized components for each synchronization scenario.
Solution Approach 2:
The system implements feedback mechanisms where browser instances can request data from the web server and receive updates when data changes. This feedback loop ensures synchronized display content while maintaining a manageable system architecture through structured communication protocols.
3Productivity
If browser instances communicate via a web server with sockets, then data transmission efficiency is improved, but the ease of operation decreases due to protocol configuration requirements
Solution Approach 1:
The web server and browser instances are equipped with sockets that enable automatic connection and communication. The system performs self-service by establishing communication channels without requiring manual configuration for each interaction, reducing operational complexity while maintaining efficient data transmission.
