Solution Overview

Problem

Existing methods for checking the operation of electronic devices in a network are inadequate for detecting non-content-impacting malfunctions and power supply issues, as they rely on analyzing message content or additional components that can malfunction.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If message content analysis is used to check device operation, then content-related malfunctions can be detected, but non-content-impacting malfunctions and power supply issues cannot be detected

Engineering Contradiction:

Improvedetection capabilityVSAvoidmalfunction detection coverage

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent replaces the mechanical/content-based analysis approach with an electromagnetic field-based approach. Instead of analyzing message content through protocol parsing, the system captures and analyzes electromagnetic emissions (noise) from the device's radio frequency circuitry. This substitution enables detection of hardware malfunctions, power supply issues, and component failures that do not affect message content, while still maintaining the ability to detect content-related issues.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If dedicated components are added to identify malfunctions, then detection accuracy improves, but device complexity and potential failure points increase

Engineering Contradiction:

Improvemalfunction detection accuracyVSAvoidcomponent count

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies the self-service principle by using the device's own electromagnetic emissions as the detection signal. The radio frequency circuitry that normally transmits messages also generates characteristic electromagnetic noise patterns that serve as fingerprints for device health monitoring. No separate sensing components are needed - the device's operational emissions themselves provide the diagnostic information, eliminating the need for additional dedicated monitoring components.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent makes the electromagnetic emission detection serve multiple functions: it simultaneously monitors hardware integrity, power supply status, component functionality, and message transmission health. A single detection mechanism (electromagnetic noise analysis) replaces what would otherwise require multiple specialized sensors and components, achieving universal monitoring capability across all device subsystems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If additional monitoring mechanisms are implemented, then malfunction detection capability improves, but energy consumption and communication channel congestion increase

Engineering Contradiction:

Improveoperation checking reliabilityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent uses electromagnetic noise as an intermediary carrier that conveys device health information without requiring additional communication transactions. Instead of having the device actively report its status through message exchanges (which would consume energy and congest channels), the electromagnetic emissions passively carry diagnostic information that can be captured and analyzed by external monitoring equipment, eliminating the need for additional energy expenditure by the monitored device.

Inventive Principle:

Principle #24Intermediary (Mediator)
