Location-Aware Information Providing Device for Targeted Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing danger information notification systems fail to provide targeted and relevant notification information to individuals based on their positional information and moving directions, leading to inefficiencies in alerting individuals about potential dangers.
Innovation Solution
An information providing device that acquires positional information of a target person and informs them of relevant alerting information based on their position, moving direction, and type of information tied to their identification, while also allowing for emergency notifications and adaptable notification methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If notification information is provided to all target persons regardless of their position and movement, then the system ensures comprehensive coverage, but the relevance and effectiveness of notifications deteriorates due to lack of personalization
Solution Approach 1:
The system applies local quality by customizing notification content based on each target person's specific position, moving direction, and registered preferences. Different individuals receive different notification information even when in the same area, ensuring that each person gets personally relevant alerts rather than generic notifications.
Solution Approach 2:
The system performs preliminary action by pre-registering each target person's identification information, positional information, and moving direction before notifications are sent. This advance preparation allows the system to quickly determine relevant notifications without real-time analysis delays.
2Loss of information
If the system filters notifications based on position and moving direction, then the relevance of notifications improves, but the complexity of the notification system increases
Solution Approach 1:
The system applies self-service by having target persons pre-register their own identification information, positional information, and moving direction data. This eliminates the need for complex real-time tracking and analysis systems, as the filtering logic simply matches current position against pre-registered preferences.
Solution Approach 2:
By performing preliminary registration of position and movement preferences before notifications are needed, the system reduces runtime complexity. The notification process becomes a simple lookup and comparison operation rather than requiring complex real-time analysis.
3Reliability
If emergency notification information is provided regardless of position, then the urgency and importance of emergency alerts is maintained, but the precision of targeted emergency notification deteriorates
Solution Approach 1:
The system ensures reliable emergency notification delivery by pre-registering all target persons and their positions in advance. When an emergency occurs, the system can quickly identify and notify all relevant persons without complex real-time location tracking, maintaining both reliability and precision.
