Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wireless networks support a diverse range of devices with varying data traffic profiles, then network versatility and service coverage are improved, but network complexity and resource management difficulty increase

Engineering Contradiction:

Improvenetwork versatilityVSAvoidnetwork complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments sensing capability discovery into distinct message types (sensing capability discovery requests and responses) with specific information elements. This segmentation allows the network to handle different device types and sensing capabilities through structured, modular message exchanges, reducing the complexity of managing diverse device profiles while maintaining network versatility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent creates a universal sensing capability discovery framework that can accommodate multiple device types (UE, infrastructure equipment) and sensing technologies (imminent sensing, non-imminent sensing, coordinated sensing). The standardized message structure and information elements provide a multi-functional platform that handles diverse sensing requirements through a common protocol, reducing network complexity while supporting broad adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Measurement precision

If sensing capability discovery requests are transmitted to multiple network devices, then sensing coordination accuracy is improved, but communication overhead and latency increase

Engineering Contradiction:

Improvesensing coordination accuracyVSAvoidcommunication latency

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent implements preliminary action by having devices transmit sensing capability discovery requests before actual sensing operations begin. This allows the network to pre-establish sensing capability information, identify suitable sensing devices, and coordinate sensing resources in advance. The sensing capability information is discovered and stored beforehand, reducing communication latency during actual sensing operations while maintaining accurate sensing coordination.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If sensing capability information is exchanged between devices, then sensing operation reliability is improved, but message overhead and processing complexity increase

Engineering Contradiction:

Improvesensing operation reliabilityVSAvoidmessage overhead

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent extracts only the essential sensing capability information elements needed for sensing operations into standardized message structures. Instead of exchanging complete device profiles or redundant data, the system extracts specific sensing capability parameters (sensing technology type, sensing accuracy, sensing range) into dedicated information elements within sensing capability discovery requests and responses. This reduces message overhead while ensuring all necessary information for reliable sensing operations is transmitted.

Inventive Principle:
