Solution Overview

Problem

In complex processing setups with multiple devices, audio data analysis for diagnostics becomes cumbersome due to the large volume of data generated by different types of sound from various processing devices, making it difficult to efficiently identify and diagnose device states.

Innovation Solution

An audio identification device that captures audio signals in a processing setup, uses a processor to retrieve relevant audio data from a database based on device identification, and analyzes these signals to determine the state of processing devices, providing a response based on the analysis, which can include corrective actions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If audio data from multiple processing devices is captured and analyzed for diagnostics, then diagnostic capability is improved, but data complexity and analysis difficulty increase

Engineering Contradiction:
Improvediagnostic capabilityVSAvoiddata complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the audio data analysis by creating separate audio profiles for each processing device type. The system divides the complex multi-device audio environment into individual device signatures, allowing each device to be analyzed independently against its own reference profile, thereby reducing overall data complexity while maintaining diagnostic capability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transforms the audio data by extracting specific parameters such as frequency content, amplitude, and temporal characteristics. By converting raw audio signals into standardized parametric representations, the system reduces data complexity while preserving the essential diagnostic information needed for reliable device state identification

Inventive Principle:
Principle #35Parameter changes

2Reliability

If audio data from multiple processing devices is captured and analyzed for diagnostics, then diagnostic capability is improved, but analysis time increases

Engineering Contradiction:
Improvediagnostic capabilityVSAvoidanalysis time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent performs preliminary action by pre-establishing audio profiles for each processing device type before actual diagnostic analysis. These reference profiles are created in advance and stored for quick comparison, eliminating the need for complex real-time analysis of multi-device audio environments and significantly reducing analysis time while maintaining diagnostic accuracy

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If comprehensive audio data is collected from all processing devices, then diagnostic accuracy is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvediagnostic accuracyVSAvoidease of operation
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent extracts only the essential audio characteristics needed for diagnostics by comparing actual device sounds against pre-established audio profiles. This extraction approach captures the necessary diagnostic information without requiring operators to process comprehensive raw audio data from all devices, thereby maintaining diagnostic accuracy while significantly improving ease of operation

Inventive Principle:
Principle #2Taking out (Extraction)
