Solution Overview

Problem

Existing systems lack the capability for quick initial response to accidents involving injured persons or urgent cases, particularly in detecting and analyzing the situation to provide timely and appropriate notifications.

Innovation Solution

A notification device and system that utilizes cameras to detect accidents, analyze the condition of injured persons or urgent cases, and determine appropriate coping methods, including first aid and medical procedures, by deriving detailed information through video analysis and personal data, and notifying relevant targets.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If video data is captured and analyzed to detect accidents and determine coping methods, then the accuracy and timeliness of notifications is improved, but the device complexity and processing requirements increase

Engineering Contradiction:
Improvedetection accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The notification device is divided into distinct functional units: a video data acquisition unit, an accident detection unit that analyzes the video data, and a notification unit. This segmentation allows each unit to specialize in specific tasks, improving detection accuracy while managing system complexity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an accident detection unit as an intermediary between video data acquisition and notification. This intermediary unit processes video data to identify accidents and determines appropriate coping methods, bridging the gap between raw video input and actionable notifications while maintaining system organization.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If detailed information is derived from video data and personal data, then the productivity and response speed is improved, but the loss of time for data processing increases

Engineering Contradiction:
Improveresponse speedVSAvoidprocessing time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The notification device performs preliminary actions by continuously acquiring and pre-processing video data before accidents occur. The accident detection unit is ready to immediately analyze pre-captured video data when an accident is detected, reducing the time needed for real-time processing and improving overall response speed.

Inventive Principle:
Principle #10Preliminary action

AI summary

A notification device (10) according to an example embodiment of the present disclosure includes an accident occurrence detection unit (101) that detects occurrence of an accident from a video captured by one or a plurality of cameras, an analysis unit (102) that analyzes the video to derive detailed information regarding an analysis target person involved with the accident, a determination unit (103) that determines a coping method for the analysis target person on the basis of the detailed information; and a notification unit (104) that notifies the notification target of the determined coping method. As a result, it is possible to achieve a quick initial response with respect to an analysis target person such as an injured person or an urgent case.
