Monitoring Device Alert Segmentation for Related Event Detection

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing monitoring systems fail to distinguish between insignificant events and precursors of significant events, such as a person sleeping, which can lead to theft, necessitating improved alert mechanisms.

Innovation Solution

A monitoring device that detects a first event and notifies a first alert, and upon detecting a second event related to the first event, notifies a distinct second alert, allowing for differentiated responses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a monitoring system notifies alerts for all detected events, then the monitoring person is informed of all occurrences, but the monitoring person cannot distinguish between insignificant events and significant threats

Engineering Contradiction:

Improvealert accuracyVSAvoidevent distinction information

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent segments alerts into multiple types (first alert for initial events, second alert for related subsequent events) to differentiate between various event scenarios. This segmentation allows the monitoring system to provide nuanced information about event sequences and relationships, enabling the monitoring person to distinguish between insignificant isolated events and significant threatening event patterns.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If the monitoring system uses a single alert type for all events, then the system is simple to operate, but the monitoring person cannot respond appropriately to different event severity levels

Engineering Contradiction:

Improvealert notification simplicityVSAvoidresponse differentiation capability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements a dynamic alert notification system that adapts the type of alert based on the detected event sequence. When a second event related to a first event is detected, the system dynamically switches from notifying a first alert to notifying a second alert. This dynamic adaptation maintains operational simplicity while providing versatility in response differentiation.

Inventive Principle:

Principle #15Dynamics

3Reliability

If the monitoring system detects and notifies all events equally, then no important events are missed, but the monitoring person cannot prioritize responses to potential threats

Engineering Contradiction:

Improveevent detection completenessVSAvoidresponse prioritization time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent establishes a preliminary framework where the system proactively identifies and notifies second alerts for event sequences that indicate potential threats. By preliminarily categorizing event patterns and preparing differentiated alert notifications, the system enables the monitoring person to prioritize responses without losing detection completeness, as the alert type itself provides prioritization guidance.

Inventive Principle:

Principle #10Preliminary action

AI summary

An appropriate response to an event is recommended to a monitoring person. An event detection unit (12) detects an event based on video data, and an alert unit (13) issues a first alert when a first event is detected, and issues a second alert that is distinguished from the first alert when a second event relating to the first event is further detected in addition to the first event.
