Solution Overview

Problem

Existing vehicle-mounted electronic devices lack the ability to efficiently share content across multiple user terminals within a vehicle, limiting the integration and synchronization of content information and vehicle-related data for multiple occupants.

Innovation Solution

An electronic device mounted on a vehicle is equipped with a communication module to connect with multiple user terminals, a display module to synchronize and display a shared user interface (UI) that combines content information from these terminals with vehicle-related information, and a processor to manage this integration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the vehicle-mounted electronic device connects to multiple user terminals to share content, then the content sharing capability and user experience are improved, but the system complexity and synchronization difficulty increase

Engineering Contradiction:
Improvecontent sharing capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The vehicle-mounted electronic device serves as an intermediary that receives content information from multiple user terminals, processes it centrally, and distributes synchronized displays back to all terminals. This mediator approach allows multiple devices to share content without direct peer-to-peer complexity, resolving the contradiction by centralizing coordination functions.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The vehicle-mounted electronic device performs multiple functions: receiving content from various terminals, processing synchronization, displaying on its own screen, and distributing synchronized information back to all terminals. This multi-functionality consolidates what would otherwise require separate specialized components, reducing overall system complexity while maintaining versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If the vehicle-mounted electronic device synchronizes display across multiple user terminals, then the information consistency is improved, but the processing load and synchronization time increase

Engineering Contradiction:
Improveinformation consistencyVSAvoidsynchronization time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The vehicle-mounted electronic device collects content information from all user terminals in advance before initiating the synchronized display process. By gathering and preprocessing all content data beforehand, the system minimizes the actual synchronization time when display is needed, ensuring information consistency without excessive processing delays.

Inventive Principle:
Principle #10Preliminary action

3Loss of information

If the vehicle-mounted electronic device integrates content information and vehicle-related information from multiple sources, then the information completeness is improved, but the data processing complexity increases

Engineering Contradiction:
Improveinformation completenessVSAvoiddata processing complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The vehicle-mounted electronic device merges content information from multiple user terminals with vehicle-related information into a single unified display interface. This consolidation approach ensures all information is available together (improving completeness) while using one processing unit (the vehicle-mounted device) to handle all integration tasks, avoiding the need for complex distributed processing across multiple devices.

Inventive Principle:
Principle #5Merging (Combining)
