Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If existing systems manage and multiplex service information from sensor data in IoT networks over 5G wireless networks, then connectivity between sensors and network services nodes is established, but resource utilization is inefficient and network performance is suboptimal

Engineering Contradiction:

Improvenetwork performanceVSAvoidresource utilization

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The system segments service information from multiple sensors into distinct service portfolios, grouping related sensors and services together. This segmentation allows for more efficient routing and management of data flows, improving network performance while reducing redundant resource consumption by handling only relevant data subsets.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A service multiplexer is introduced as an intermediary component that sits between sensors and network services nodes. This multiplexer intelligently routes service information from sensors to appropriate network services nodes, optimizing resource utilization and improving overall network performance by eliminating inefficient direct connections.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If service information from multiple sensors is multiplexed and routed through existing systems, then data management is performed, but routing efficiency is suboptimal leading to increased network resource expenditure

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSLoss of energy

Solution Approach 1:

The service multiplexer performs multiple functions including data collection, service portfolio creation, intelligent routing, and service information management. This multi-functional approach simplifies the overall system operation by consolidating routing decisions in a single intelligent component, improving data routing efficiency while reducing network resource expenditure through optimized paths.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically changes routing parameters based on service portfolio configurations and network conditions. By adjusting routing decisions according to service types and sensor groupings, the system achieves more efficient data routing and reduces unnecessary network resource consumption.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If sensors and IoT devices are individually connected to network services nodes, then service coverage is provided, but system complexity increases and resource utilization decreases

Engineering Contradiction:
