Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wireless communication networks use traditional handover methods based on basic signal strength, then device handover between access nodes can be performed, but the network cannot effectively utilize radio signal levels to control wireless network slice usage or efficiently handover devices between slices

Engineering Contradiction:
Improvenetwork slice selection capabilityVSAvoidcommunication service reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies parameter changes by monitoring specific radio signal parameters (RSRP, SINR, throughput) and using them as decision criteria for network slice selection and handover. Instead of using basic signal strength alone, the system evaluates multiple radio signal parameters against predefined thresholds to determine when to switch slices, enabling adaptive network slice usage based on actual radio conditions.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system implements feedback mechanisms by continuously monitoring radio signal parameters and using this information to dynamically adjust network slice selection. The network control system receives feedback about current signal conditions and makes real-time decisions about slice handover, creating a closed-loop control system that adapts to changing radio conditions.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If the network monitors multiple radio signal parameters for slice selection, then slice selection accuracy improves, but the complexity of the control system increases

Engineering Contradiction:
Improveradio signal measurement accuracyVSAvoidcontrol system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the control system into distinct functional components: a monitoring function that tracks radio signal parameters, an evaluation function that compares parameters against thresholds, and a decision function that triggers slice handover. This modular approach allows precise measurement of multiple parameters while managing system complexity through functional separation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system uses dynamics by implementing configurable thresholds and monitoring parameters that can be adjusted based on network conditions and service requirements. The control system adapts its behavior dynamically, changing which parameters are monitored and what thresholds apply, rather than using fixed rigid control logic.

Inventive Principle:
Principle #15Dynamics
