Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If network switch devices use traditional configuration methods, then device complexity is reduced, but traffic flow management precision deteriorates

Engineering Contradiction:
Improvetraffic flow configuration precisionVSAvoidconfiguration system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent introduces a configuration system as an intermediary component that mediates between users and the network switch device. This external configuration system handles the complexity of traffic flow management, allowing the network switch device itself to remain relatively simple while achieving precise traffic flow configuration through the intermediary's processing and management capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If network switch devices implement detailed traffic flow configurations, then traffic monitoring capability is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvetraffic monitoring capabilityVSAvoidconfiguration ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The configuration system provides self-service capabilities by automatically processing configuration parameters, validating settings, and managing traffic flow rules without requiring deep manual intervention. The system can automatically generate configurations based on provided parameters, reducing the operational burden on users while maintaining detailed and reliable traffic monitoring capabilities.

Inventive Principle:
Principle #25Self-service

3Productivity

If network switch devices lack structured configuration methods, then device complexity is low, but traffic management efficiency deteriorates

Engineering Contradiction:
Improvetraffic management efficiencyVSAvoidconfiguration system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the traffic management function into a separate configuration system that handles complex processing independently from the network switch device's core forwarding functions. This segmentation allows efficient traffic management through specialized configuration processing while keeping the network switch device's structure relatively simple and focused on its primary packet forwarding role.

Inventive Principle:
Principle #1Segmentation
