Personalized Disaster Image Delivery for Evacuation Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disaster warning systems provide uniform information to all users, failing to account for individual user-specific information, leading to inappropriate responses to disasters.
Innovation Solution
An information providing system that acquires user-specific information and generates personalized disaster images based on user attributes and behavior, providing tailored disaster information including evacuation routes and refuge locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If uniform warning information is provided to all users, then the information providing system is simple and easy to operate, but users cannot clearly recognize the degree of danger corresponding to their specific situation
Solution Approach 1:
The patent segments the uniform warning information into personalized information by dividing users into different groups based on their attributes (age, location, disaster experience) and behavior patterns. Each segment receives tailored warning information including specific evacuation routes and refuge locations relevant to their situation, thereby improving danger recognition accuracy without overwhelming the system with excessive complexity.
Solution Approach 2:
The patent applies local quality by providing different information content to different user segments based on their specific needs. For example, elderly users receive simpler language and more detailed evacuation instructions, while users in high-risk areas receive more frequent and specific warnings. This localized information quality enhances relevance and effectiveness for each user group.
2Reliability
If personalized disaster information is generated for each user, then users can appropriately recognize and respond to disaster situations, but the information processing becomes more complex and resource-intensive
Solution Approach 1:
The patent implements preliminary action by collecting and storing user attributes (age, location, disaster experience) and behavior information in advance before disasters occur. The system pre-processes this data to create user profiles that can be quickly matched with disaster information during emergencies. This pre-prepared framework enables rapid generation of personalized warnings without requiring complex real-time processing during the disaster itself.
Solution Approach 2:
The patent uses copying by creating template-based warning information structures that can be replicated and adapted for different user segments. Instead of generating entirely unique information for each user, the system uses standardized templates customized with user-specific data points, significantly reducing processing complexity while maintaining personalization effectiveness.
3Loss of information
If detailed user information is collected and processed, then personalized warning information can be generated, but the system requires more resources and processing power
Solution Approach 1:
The patent extracts only the most critical user attributes and behavior information needed for effective personalization, rather than processing all available user data. The system identifies and extracts key factors such as location, age group, and disaster experience level that have the highest impact on warning information effectiveness, reducing processing requirements while maintaining personalization quality.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting the level of detail and complexity in warning information based on user characteristics. For example, the system modifies language complexity, information density, and presentation format according to user attributes, optimizing resource usage by providing appropriate detail levels rather than maximum detail to all users.
