Solution Overview

Problem

Existing solutions for data exchange between passengers' mobile devices in vehicles rely on external mobile phone networks, which are unstable in certain geographical areas and vehicles, limiting connectivity.

Innovation Solution

A local data exchange system within the vehicle using an embedded computer system to manage communication between passengers' devices, independent of mobile network quality, utilizing Bluetooth Low Energy technology for short-range communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If external mobile phone network (4G/5G) is used for data exchange between passengers' devices, then passengers can communicate and entertain themselves, but the connection stability deteriorates in certain geographical areas and vehicles

Engineering Contradiction:
Improvedata exchange capabilityVSAvoidconnection stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The vehicle's embedded computer system acts as an intermediary device that receives data from one mobile device and transmits it to another mobile device within the vehicle. This local mediation eliminates dependency on external mobile networks, ensuring stable communication between passengers regardless of geographical location or network coverage conditions.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a local network is created within the vehicle managed by the vehicle's computer system, then connection stability is improved and network dependency is eliminated, but device complexity increases

Engineering Contradiction:
Improveconnection stabilityVSAvoidcommunication system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The vehicle's embedded computer system is designed to perform multiple functions: it manages the local network infrastructure, routes data between multiple mobile devices, and can directly process simple communication requests. This multi-functionality consolidates what would otherwise require separate dedicated components, maintaining reliability while controlling complexity through versatile system design.

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

3Ease of operation

If proprietary communication protocol is used within the vehicle, then authentication and configuration are simplified, but adaptability to different device types is reduced

Engineering Contradiction:
Improveconfiguration simplicityVSAvoiddevice compatibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The vehicle's computer system serves as a protocol translation intermediary. It accepts data in various formats from different mobile device types, processes and standardizes the information internally using the proprietary protocol, and transmits it to the appropriate recipient devices. This mediation layer simplifies authentication for passengers while maintaining broad device compatibility through format conversion.

Inventive Principle:
Principle #24Intermediary (Mediator)
