Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If periodic update requests are monitored to determine entity availability, then reliability of service continuity is improved, but device complexity increases due to timer management and availability status tracking

Engineering Contradiction:

Improveservice continuityVSAvoidtimer management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system implements a feedback mechanism where entities periodically send update requests and timers track their availability status. The network side monitors these periodic signals to determine entity availability, creating a closed-loop feedback system that ensures reliable service continuity while managing complexity through standardized monitoring procedures.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

Entities autonomously manage their own availability by sending periodic update requests and maintaining local timers. This self-service approach allows entities to self-report their status without requiring complex external monitoring systems, reducing overall system complexity while ensuring reliable availability detection.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If availability status determination is implemented, then adaptability for functionality assignment is improved, but loss of time increases due to periodic monitoring overhead

Engineering Contradiction:

Improvefunctionality assignment flexibilityVSAvoidmonitoring overhead time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system uses periodic update requests with configurable intervals to determine entity availability. This periodic action allows the network to adapt to changing entity statuses and assign functionalities accordingly, while the configurable period balances adaptability needs against time loss from monitoring overhead.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system allows dynamic adjustment of timer values and monitoring parameters based on service requirements. By changing these parameters, the system can optimize the balance between adaptability for functionality assignment and time loss from monitoring, tailoring the periodic update intervals to specific operational contexts.

Inventive Principle:

Principle #35Parameter changes
