Solution Overview

Problem

The increasing bandwidth demands and load on a single communication module in vehicles due to numerous connected services exceed operational capabilities, leading to inefficiencies and potential service disruptions.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single communication module is used to handle all communication services, then the device complexity is low, but the bandwidth capacity and service handling capability become insufficient

Engineering Contradiction:

Improvebandwidth capacityVSAvoidnumber of communication modules

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The communication system is segmented into multiple independent communication modules (first communication module, second communication module, etc.), each capable of handling specific services. This segmentation allows the system to distribute communication loads across multiple modules, thereby increasing overall bandwidth capacity and service handling capability while maintaining manageable complexity through modular architecture.

Inventive Principle:

Principle #1Segmentation

2Productivity

If multiple communication modules are deployed to handle increased bandwidth demands, then the service handling capability improves, but the device complexity increases

Engineering Contradiction:

Improveservice handling capabilityVSAvoidsystem configuration complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system implements a determination unit that continuously monitors the operational status of each communication module and dynamically adjusts service allocation based on real-time feedback. When a module is determined to be normally operating, its services are activated; when abnormal, services are automatically switched to other modules. This feedback mechanism simplifies system management by providing automated status-based control, reducing the complexity burden of having multiple modules.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system employs dynamic service allocation where the assignment of communication services to specific modules is not fixed but can change based on operational status. The switching unit enables dynamic reconfiguration of service routes, allowing the system to adapt to changing conditions and optimize performance, thereby improving service handling capability without proportionally increasing operational complexity.

Inventive Principle:

Principle #15Dynamics

3Reliability

If communication services are statically allocated to specific modules, then the system configuration is simple, but the reliability decreases when module failures occur

Engineering Contradiction:

Improvecommunication service continuityVSAvoidservice allocation mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system changes the operational parameters (service allocation status) of communication modules based on their determined operational state. When modules are normally operating, their service parameters are set to active; when abnormal, parameters are changed to redirect services to other modules. This parameter-based control mechanism enhances reliability by enabling automatic adaptation to failures while maintaining relatively simple system architecture through standardized parameter management.

Inventive Principle:

Principle #35Parameter changes

4Reliability

If all communication modules operate at full capacity to maximize bandwidth utilization, then the productivity is high, but the system stability decreases under error conditions

Engineering Contradiction:

Improvesystem stabilityVSAvoidbandwidth utilization

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system prepares compensatory measures in advance by establishing multiple communication modules as backups for each other. Before failures occur, the system configures redundant communication paths and service allocation rules that enable automatic failover. This prior cushioning ensures that when a module fails, services can be smoothly transferred to other modules, maintaining system stability and continued productivity without complete service interruption.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)
