Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional spectrum analyzers are used, then signal analysis capability is provided, but device size and weight become large and bulky

Engineering Contradiction:
Improvesignal analysis capabilityVSAvoiddevice weight
Core Design Contradiction:
Measurement precisionVSWeight of moving object

Solution Approach 1:

The system divides the spectrum analyzer functionality into two separate components: a portable signal analyzer device that performs RF signal capture and cognitive scanning analysis, and a separate mobile computing device that provides user interface and displays analysis results. This segmentation allows the signal analysis hardware to be compact and lightweight while maintaining full analytical capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a co-processing unit as an intermediary component that bridges the signal analyzer and mobile computing device. The co-processing unit handles signal processing tasks and communicates with both the RF receiver and the mobile device, enabling the system to achieve sophisticated signal analysis in a compact form factor by distributing processing functions across multiple components.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If conventional spectrum analyzers are used, then signal analysis is performed, but operator training requirements increase

Engineering Contradiction:
Improvesignal analysis capabilityVSAvoidoperator training requirement
Core Design Contradiction:

Solution Approach 1:

The signal analyzer incorporates automated cognitive scanning analysis capabilities that perform complex signal detection, classification, and characterization without requiring manual operator intervention. The system automatically processes RF signals, identifies signal types, and presents results in an easily interpretable format, thereby reducing the need for extensive operator training while maintaining advanced analytical capabilities.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The portable signal analyzer is designed to perform multiple functions including RF signal capture, cognitive scanning, signal classification, and result presentation through integration with mobile devices. This multi-functionality consolidates what would traditionally require multiple specialized instruments and extensive training into a single unified system that is easier to operate.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Measurement precision

Solution Approach 1:

The patent replaces traditional mechanical signal analysis methods with cognitive scanning analysis that uses advanced signal processing algorithms and machine learning techniques. Instead of merely displaying power spectral density, the system automatically detects, classifies, and characterizes various signal types (communication signals, radar signals, electronic warfare signals) and provides comprehensive RF environment analysis, thereby preventing information loss about complex RF environment characteristics.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Measurement precision

If conventional spectrum analyzers are used, then signal measurement capability is provided, but portability and ease of deployment are reduced

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent merges the signal analyzer with a mobile computing device into an integrated portable system. The signal analyzer captures RF signals and performs cognitive scanning analysis, while the mobile device provides a familiar user interface and displays results. This merging creates a portable system that maintains full signal measurement capability while enabling easy deployment in field settings such as military aircraft, vehicles, or handheld applications.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Techniques are provided for implementing a portable spectrum analyzer. An example system, according to an embodiment, includes a signal analyzer including an RF receiver to receive RF signals from an antenna, an analog-to-digital converter to generate a sampled signal based on the received RF signals, and a signal analysis co-processor to perform cognitive scanning analysis of the sampled signal. The cognitive scanning analysis includes detection, identification, and characterization of digital/analog signal(s) embedded in the sampled signal. The system may further include a communications interface circuit to provide communication between the signal analyzer and an associated mobile host platform (e.g., smartphone). The communication includes transmitting results of the cognitive scanning analysis to the mobile host and receiving parameters from the mobile host to control the operation of the cognitive scanning analysis. The signal analyzer and mobile host are coupled through a shared enclosure such as a hinged case, sleeve, or wallet.
