Solution Overview

Problem

In-vehicle wireless communication systems face resource conflicts and interference between different communications domains, leading to reduced information receiving quality due to independent resource selection and multiplexing issues.

Innovation Solution

A centralized communications apparatus allocates and configures distinct resource pools for each communications domain, employing time-division multiplexing to avoid conflicts and reduce interference, ensuring proper resource utilization and improved information reception.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If resources are independently selected in each communications domain, then each domain can operate autonomously, but resource conflicts occur between domains leading to transmission failures

Engineering Contradiction:
Improveautonomous operation of communications domainVSAvoidtransmission reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a master node as an intermediary that coordinates resource allocation across multiple communications domains. The master node receives resource requirements from slave nodes, selects appropriate resources from available pools, and allocates them to avoid conflicts between domains, thereby maintaining transmission reliability while preserving domain autonomy.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If resources are multiplexed in frequency domain across communications domains, then resource utilization improves, but receiving processes are blocked by other communications apparatus reducing information receiving quality

Engineering Contradiction:
Improveresource utilization efficiencyVSAvoidinformation receiving quality
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent segments the frequency domain resources into separate resource pools for different communications domains. Instead of allowing all domains to access the entire frequency spectrum simultaneously, each domain is allocated specific frequency resources, preventing receiving process blocking while maintaining efficient resource utilization through dedicated pools.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If a single resource pool is used for all communications domains, then resource management is simplified, but resource conflicts and interference increase reducing communication quality

Engineering Contradiction:
Improveresource management complexityVSAvoidcommunication quality
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent creates a universal resource management framework where the master node performs centralized resource allocation for multiple slave nodes across different domains. This multi-functional approach allows a single coordination point to manage resources for all domains, simplifying overall management while preventing conflicts through intelligent allocation decisions.

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