Solution Overview

Problem

Current sound recognition systems are inadequate for identifying complex situations or scenes based on multiple sounds due to insufficiently provisioned and varied sound databases, leading to unreliable and erroneous identifications, as they primarily focus on single sound identification and lack effective search or selection systems.

Innovation Solution

A device that identifies scenes by capturing and classifying multiple sounds in chronological order, using complementary data from connected devices to refine sound classes and distinguish between similar acoustic fingerprints, thereby improving scene interpretation and reducing uncertainty.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If current sound recognition systems use single sound identification, then the system complexity is reduced, but the reliability of scene identification deteriorates

Engineering Contradiction:
Improvesystem complexityVSAvoidscene identification reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent segments the sound identification process into multiple stages: individual sound classification, temporal ordering, and scene-level synthesis. By analyzing sounds in discrete temporal segments and combining them through ordering relationships, the system achieves reliable scene identification without requiring a monolithic complex system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a temporal ordering dimension to sound analysis. Instead of merely classifying individual sounds, the system orders them chronologically and uses this temporal dimension to distinguish between different scenes that may produce similar sound sequences, thereby improving reliability without proportionally increasing complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If sound databases are insufficiently provisioned and varied, then the device complexity is reduced, but the measurement precision of sound classification deteriorates

Engineering Contradiction:
Improvedatabase complexityVSAvoidsound classification precision
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The system performs self-service by automatically collecting, organizing, and annotating sound samples from the environment. It builds its own database through continuous operation, capturing sounds during various scenes and using these real-world examples to train and refine its classification models, thereby improving precision without requiring externally provisioned comprehensive databases.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent implements feedback mechanisms where the system uses identified scenes and their associated sounds to continuously improve its classification accuracy. By comparing detected sounds with actual scene contexts and using this feedback to refine future identifications, the system progressively enhances measurement precision.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If current sound identification systems use simple sound classes, then the ease of operation is improved, but the loss of information about sound variability increases

Engineering Contradiction:
Improveease of sound classificationVSAvoidsound variability information
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent introduces dynamic adaptability to sound classification by allowing the system to automatically adjust the granularity and specificity of sound classes based on the context and available information. The classification system evolves from simple to more detailed levels as needed, maintaining ease of operation while capturing sound variability through contextual enrichment.

Inventive Principle:
Principle #15Dynamics
