Solution Overview

Problem

Current wireless communication systems in vehicles require manual configuration and selection of wireless devices for connections, which can be cumbersome and inefficient when multiple devices are present.

Innovation Solution

A vehicle controller determines a selected wireless device based on received signal strength indicator (RSSI), connection intention, and device preference to automate the connection process, using multiple communication protocols for seamless pairing and streaming.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual configuration and selection of wireless devices is used, then connection reliability is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveconnection reliabilityVSAvoidease of connection
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system automatically detects available wireless devices, evaluates their connection suitability based on RSSI and device preferences, and establishes connections without requiring manual user configuration or selection, thereby maintaining connection reliability while significantly improving ease of operation

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors RSSI values and device connection states, using this feedback to dynamically adjust connection decisions and maintain optimal connections, ensuring reliability while operating autonomously without manual intervention

Inventive Principle:
Principle #23Feedback

2Ease of operation

If automatic device selection based on RSSI is implemented, then ease of operation is improved, but measurement precision requirements worsen

Engineering Contradiction:
Improveease of connectionVSAvoidRSSI measurement precision
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system introduces device preferences as an intermediary layer that combines with RSSI measurements to make connection decisions, reducing the burden on RSSI measurement precision alone while maintaining overall connection quality through multiple evaluation criteria

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system changes the decision-making parameters from relying solely on RSSI to a composite evaluation including RSSI trends, connection intentions, and device preferences, thereby reducing sensitivity to RSSI measurement precision requirements while improving overall connection selection accuracy

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple wireless protocols are used for seamless pairing, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improveprotocol compatibilityVSAvoidcommunication system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The vehicle communication system is designed to support multiple wireless communication protocols (Bluetooth, Wi-Fi, etc.) within a single unified system, enabling it to adapt to different device types and connection requirements while presenting a consistent user interface and connection management experience

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