Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Media devices installed in buildings, such as hotels and nursing homes, need to display location-specific information and guide users to emergency exits during emergencies, but existing systems lack the capability to differentiate between available and unavailable exits and provide real-time fire escape routes effectively.

Innovation Solution

A media device with a display unit, signal input/output unit, and controller that receives location information from a management center to classify emergency exits, calculate and map the closest fire escape route, and output this information to users, while also transmitting rescue requests if no exits are available, and capturing and transmitting image data to external terminals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a media device displays general information from a management center, then information delivery is achieved, but location-specific emergency guidance cannot be provided

Engineering Contradiction:

Improvelocation-specific information displayVSAvoidemergency exit availability information

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system displays different information content based on the specific location of each media device within the building. The controller receives the media device's location information and uses it to determine which emergency exits are available and which are unavailable, then displays this location-specific information on the display unit. This ensures that each user sees emergency guidance relevant to their specific position in the building.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The emergency exit information is segmented into two distinct categories: available emergency exits and unavailable emergency exits. This segmentation allows the system to clearly differentiate between exits that are safe to use and those that are blocked or compromised, providing users with actionable guidance rather than a single undifferentiated list of exits.

Inventive Principle:

Principle #1Segmentation

2Reliability

If all emergency exits are displayed equally, then complete information is provided, but users cannot distinguish between available and unavailable exits

Engineering Contradiction:

Improveemergency guidance accuracyVSAvoidexit selection clarity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Different visual characteristics are applied to different types of emergency exits based on their availability status. Available emergency exits are displayed with one visual characteristic (e.g., green color or normal display), while unavailable emergency exits are displayed with a different visual characteristic (e.g., red color or dimmed display). This visual differentiation allows users to quickly identify which exits are safe to use without having to read detailed information about each exit's status.

Inventive Principle:

Principle #3Local quality

3Measurement precision

If the media device calculates fire escape routes in real-time during emergencies, then accurate route guidance is provided, but processing time and computational resources increase

Engineering Contradiction:

Improvefire escape route accuracyVSAvoidroute calculation time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system pre-calculates and stores fire escape routes from various locations in the building to the nearest emergency exits before an emergency occurs. When an emergency is detected, the controller simply retrieves the pre-calculated route information corresponding to the media device's location, rather than calculating routes in real-time. This dramatically reduces the time required to provide accurate escape route guidance during emergencies.

Inventive Principle:

Principle #10Preliminary action

4Use of energy by moving object

If the media device remains in power-off state during emergencies, then energy consumption is minimized, but emergency information cannot be displayed

Engineering Contradiction:

Improvepower consumptionVSAvoidemergency response capability

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The media device is equipped with an emergency detection mechanism that automatically activates the device when an emergency condition is detected, without requiring manual intervention or continuous power consumption. The device can remain in a low-power state during normal operation and only consumes significant power when actually needed for emergency guidance, thus balancing energy efficiency with emergency response capability.

Inventive Principle:

Principle #25Self-service

AI summary

A media device connected to an external device and a control method thereof are provided. The media device includes a display unit configured to output a plan view denoting a structure of a building, a signal input/output unit configured to, when emergency occurs, receive information regarding a location in which emergency has occurred from a management center, and a controller configured to classify a plurality of emergency exits disposed in the building into available emergency exits and unavailable emergency exits by using the location information, map a fire escape route leading to an emergency exit closest to the location in which the media device is installed, among the available emergency exits.
