Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mobility characteristics are adjusted based on measurements to optimize communication performance, then signal quality and network efficiency improve, but device complexity and processing requirements increase

Engineering Contradiction:

Improvecommunication performanceVSAvoidmobility management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The UE autonomously adjusts its own mobility characteristics based on measurements it performs, without requiring continuous network control. The UE independently determines timing adjustments for beam adjustments and measurement reports based on its mobility state, reducing network signaling overhead and processing complexity while maintaining reliable communication

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system dynamically changes mobility parameters such as timing of beam adjustments and measurement report timing based on measured mobility characteristics. By adjusting these parameters according to actual mobility conditions, the system optimizes communication performance without requiring complex structural changes to the device

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If mobility characteristics are adjusted dynamically based on measurements, then adaptability to diverse network environments improves, but loss of time for measurement and adjustment increases

Engineering Contradiction:

Improveadaptability to network environmentsVSAvoidmeasurement and adjustment time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The UE performs measurements and determines mobility characteristic adjustments in advance, before they are needed for communication optimization. By proactively adjusting timing parameters for beam adjustments and measurement reports based on current mobility state, the system prepares for future mobility conditions, reducing reaction time and improving adaptability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements periodic measurements of mobility characteristics and periodic adjustments of mobility parameters. This rhythmic approach allows the system to maintain adaptability through regular updates while managing time loss through predictable, scheduled operations rather than continuous processing

Inventive Principle:

Principle #19Periodic action

3Productivity

If mobility characteristics are adjusted based on UE measurements, then network efficiency improves, but use of energy for measurement and processing increases

Engineering Contradiction:

Improvenetwork efficiencyVSAvoidenergy for measurement and processing

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The UE performs measurements and adjustments selectively based on actual mobility conditions rather than continuously. When mobility characteristics indicate stable conditions, the UE reduces measurement frequency and processing activity. This partial action approach maintains network efficiency through necessary adjustments while conserving energy by avoiding unnecessary measurements and processing during stable periods

Inventive Principle:

Principle #16Partial or excessive action
