1Reliability

If Doppler shift compensation is performed using existing techniques, then reliability of V2X communication is improved, but device complexity increases due to ego-centric processing requirements

Engineering Contradiction:

Improvereliability of V2X communicationVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a network entity (edge computing server) as an intermediary that collects velocity information from multiple sources, computes relative speed between transceiver and receiver, and provides compensation parameters. This mediator approach transfers the complex computational burden from individual user equipment to the network infrastructure, maintaining reliability while reducing device complexity

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical/computational approach where each device independently processes velocity data with a network-based system that centralizes computation. The network entity substitutes for individual device processing, using received velocity information to derive relative speed parameters that are then provided back to devices for Doppler compensation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If local relative speed information is generated at user equipment, then measurement precision is improved, but use of energy increases due to continuous processing requirements

Engineering Contradiction:

Improvemeasurement precision of relative speedVSAvoiduse of energy by user equipment

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The network entity acts as an intermediary that performs the energy-intensive velocity data processing and relative speed computation. User equipment only needs to transmit its velocity information and receive compensation parameters, significantly reducing their energy consumption while maintaining measurement precision through network-based computation

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If complete velocity data processing is performed in centralized cloud, then reliability is improved, but loss of time increases due to data transport latency

Engineering Contradiction:

Improvereliability of speed data processingVSAvoiddata transport time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent segments the processing architecture by placing edge computing servers at network edges closer to user equipment. This segmentation allows velocity data processing and relative speed computation to occur at distributed edge locations rather than a single centralized cloud, reducing data transport distance and latency while maintaining processing reliability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transitions from a single-dimensional centralized cloud architecture to a multi-dimensional distributed edge computing architecture. By deploying processing capabilities across multiple edge servers geographically distributed near user equipment, the system reduces data transport time while maintaining reliable processing through distributed computation

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

4Productivity

If real-time relative speed data is provided to multiple user equipment, then productivity of V2X applications is improved, but loss of information increases without proper filtering

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The network entity provides customized relative speed information tailored to each user equipment and its specific application requirements. Instead of broadcasting generic data, the system filters and provides only the relevant relative speed parameters needed by each device, ensuring information accuracy and relevance while supporting multiple applications simultaneously
