Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If mechanical movement of antennas is implemented to support multiple spatial directions, then adaptability is improved, but latency increases

Engineering Contradiction:

Improvespatial direction supportVSAvoidswitching latency

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-configuring multiple mechanical states with associated latency values before communication occurs. The network node receives capability indications from the UE about supported mechanical states and their latencies, then proactively determines and applies appropriate timing adjustments in advance, eliminating the need for reactive latency compensation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically adapts communication timing based on the current mechanical state transitions. The network node monitors which mechanical state the UE is transitioning between and dynamically adjusts scheduling decisions, resource allocation, and transmission timing to account for the specific latency characteristics of each state transition, making the system flexible rather than static.

Inventive Principle:

Principle #15Dynamics

2Productivity

If mechanical states are configured for antenna switching, then communication efficiency is improved, but device complexity increases

Engineering Contradiction:

Improvecommunication efficiencyVSAvoidmechanical state management

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The network node serves as an intermediary that manages the complexity of mechanical state configurations. Rather than requiring the UE to independently manage multiple mechanical states and their timing implications, the network node receives capability indications from the UE, determines the appropriate mechanical states to use, and controls the timing and scheduling of communications based on those states, centralizing the complex management function.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The mechanical state configuration mechanism is designed to be universal and multi-functional, supporting various types of communications (uplink, downlink, sidelink) and different mechanical state scenarios through a single unified framework. The same capability indication and configuration procedures handle diverse communication scenarios, reducing the need for separate specialized mechanisms.

Inventive Principle:

Principle #6Universality (Multi-functionality)
