Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If network devices switch between networks to meet QoS constraints, then connectivity quality is improved, but reconnection delay increases

Engineering Contradiction:
Improveconnectivity qualityVSAvoidreconnection delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by predicting future network QoS metrics before actual connectivity issues occur. The machine learning model forecasts network performance based on historical data and patterns, allowing the system to proactively switch networks before degradation happens, thereby avoiding reconnection delays while maintaining quality.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors actual network performance and compares it against predicted QoS metrics. This feedback loop allows the system to adjust its network switching decisions in real-time, ensuring that switches are triggered at optimal moments to maintain connectivity quality while minimizing disruption.

Inventive Principle:
Principle #23Feedback

2Reliability

If network switching is performed to maintain QoS constraints, then service quality is improved, but connection stability deteriorates

Engineering Contradiction:
Improveservice qualityVSAvoidconnection stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

By predicting future network conditions in advance, the system can plan network switches beforehand, ensuring that transitions occur during optimal moments when connectivity disruption is minimized. This preliminary planning maintains service quality while preserving connection stability during transitions.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system prepares for potential connectivity issues by having predictive models ready to forecast network degradation. This cushioning approach allows for smooth, pre-planned transitions rather than reactive switching, thereby maintaining stability while ensuring service quality constraints are met.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Reliability

If real-time network monitoring is implemented, then connectivity quality is improved, but system complexity increases

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system uses feedback mechanisms to monitor network performance and compare actual QoS against predicted values. This feedback-driven approach simplifies decision-making by automatically triggering network switches based on predefined thresholds and predictions, reducing the need for complex manual control systems while maintaining high connectivity quality.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs self-service by using its own monitored data to feed into predictive models, which then automatically guide network switching decisions. This self-contained loop eliminates the need for external complex control systems, maintaining connectivity quality while keeping the overall system architecture relatively simple.

Inventive Principle:
Principle #25Self-service
