Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing WLAN standards are used without sensing capability definitions, then device compatibility is maintained, but sensing measurement functionality cannot be implemented

Engineering Contradiction:

Improvesensing measurement capabilityVSAvoidstandard definition complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the capability information into specific sensing measurement parameters (bandwidth, spatial streams, modulation and coding schemes, transceiving capabilities) that can be independently defined and exchanged. This allows the sensing functionality to be added as a modular extension to existing WLAN standards without requiring complete standard redefinition.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary action by defining and exchanging capability information during the session setup phase before actual sensing measurements begin. The first message frame carries capability information that enables both devices to understand each other's sensing capabilities in advance, facilitating smooth subsequent measurement operations.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If capability information is exchanged during sensing session setup, then sensing measurement compatibility is improved, but signaling overhead increases

Engineering Contradiction:

Improvesensing session compatibilityVSAvoidsignaling overhead

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent merges the capability information exchange with the existing sensing session setup procedure. The first message frame combines session establishment functionality with capability advertisement, allowing both purposes to be achieved in a single signaling interaction rather than requiring separate exchange procedures.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The first message frame serves multiple functions: it establishes the sensing session while simultaneously conveying capability information about bandwidth, spatial streams, modulation and coding schemes, and transceiving capabilities. This multi-functional approach reduces the need for additional dedicated signaling messages.

Inventive Principle:

Principle #6Universality (Multi-functionality)
