Solution Overview

Problem

Conventional security and automation systems in indoor environments lack the capability to trigger alarms based on audio detection, requiring manual intervention for event confirmation.

Innovation Solution

An indoor camera system that integrates audio and video detection to autonomously classify events like glass breaking, carbon monoxide alarms, or smoke alarms, triggering alarms or notifications without user interaction, and records relevant video footage for analysis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If conventional security systems use motion sensors or glass break sensors to trigger alarms, then alarm triggering capability is provided, but these sensors require manual intervention and are not configured in many homes and businesses

Engineering Contradiction:
Improveautomated alarm triggeringVSAvoidsensor configuration complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The indoor camera is designed to perform multiple functions: standard surveillance, audio detection, and alarm triggering. By making the camera multi-functional, the system eliminates the need for separate specialized sensors while enabling automated alarm triggering based on audio event detection.

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

Solution Approach 2:

The camera system autonomously detects audio events, classifies them, and triggers alarms without requiring manual sensor configuration or intervention. The system serves itself by using its own audio detection capabilities to initiate security responses.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If indoor cameras are configured to trigger alarms based on audio detection, then surveillance precision and response effectiveness are improved, but the system complexity increases

Engineering Contradiction:
Improveevent detection precisionVSAvoidcamera system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

An audio event classification model serves as an intermediary between the audio detection capability and the alarm triggering function. This model processes detected audio events, classifies them into relevant categories, and determines whether alarm triggering is appropriate, thereby managing system complexity through modular processing.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of time

If the camera autonomously classifies and responds to audio events, then response time is reduced, but false positives may increase

Engineering Contradiction:
Improveresponse timeVSAvoidfalse positive rate
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The system incorporates feedback mechanisms where detected audio events are analyzed and classified before triggering alarms. The classification model provides feedback on whether detected sounds warrant alarm activation, allowing the system to filter out false positives while maintaining rapid response times for genuine threats.

Inventive Principle:
Principle #23Feedback
