Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Residents often fail to evacuate promptly during disasters due to normalcy bias and majority synchronizing bias, where they perceive themselves as safe or follow the actions of others, leading to delayed evacuation and increased damage.

Innovation Solution

An information processing method that acquires and prioritizes evacuation data based on the number of evacuees and their importance levels, associating this information with the user's relationships and proximity, to effectively prompt residents to evacuate by highlighting critical evacuation statuses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If evacuation information is provided to all residents uniformly, then information coverage is improved, but information relevance and effectiveness deteriorate due to normalcy bias and majority synchronizing bias

Engineering Contradiction:

Improveevacuation information deliveryVSAvoidevacuation decision accuracy

Core Design Contradiction:

Loss of informationVSReliability

Solution Approach 1:

The patent applies local quality by customizing evacuation information based on individual user characteristics, relationships, and proximity to disaster areas. Instead of uniform information delivery, the system adjusts information content, timing, and delivery method according to each user's specific context, including their social relationships and spatial proximity to affected areas.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system performs preliminary actions by pre-establishing user profiles, relationships, and proximity data before disasters occur. This allows the system to quickly deliver personalized evacuation information during emergencies without needing to process user data in real-time, thereby overcoming the delays caused by normalcy bias through pre-prepared, targeted information delivery.

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If evacuation information is delayed to confirm actual evacuation status, then information accuracy is improved, but evacuation response time deteriorates

Engineering Contradiction:

Improveevacuation status accuracyVSAvoidevacuation response time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system pre-establishes user profiles, relationships, and proximity data before disasters occur. This allows the system to quickly deliver personalized evacuation information during emergencies without needing to process user data in real-time, thereby overcoming the delays caused by normalcy bias through pre-prepared, targeted information delivery.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms by monitoring evacuation status and adjusting information delivery accordingly. It provides continuous updates to users based on their evacuation progress and the evolving disaster situation, allowing for real-time adjustments that maintain information accuracy without delaying initial evacuation warnings.

Inventive Principle:

Principle #23Feedback

3Quantity of substance

If comprehensive evacuation data is provided to users, then information completeness is improved, but information processing complexity and user decision difficulty worsen

Engineering Contradiction:

Improveevacuation information volumeVSAvoidinformation processing complexity

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The system extracts and prioritizes only the most critical evacuation information relevant to each user based on their relationships and proximity to disaster areas. By filtering out unnecessary data and focusing on high-priority information, the system reduces cognitive load while maintaining essential information completeness for informed evacuation decisions.

Inventive Principle:

AI summary

Information for determining whether to evacuate or not is provided to a user by a computerized process. The process includes: acquiring a number of evacuees for each of a plurality of targets corresponding to a predetermined user; selecting a target of the plurality of targets based on the acquired numbers of evacuees for the plurality of targets and importance levels respectively set for the plurality of targets; and associating information on the selected target with information on the acquired number of evacuees for the selected target and outputting the information on the selected target and the information on the acquired number of evacuees for the selected target to the predetermined user.
