Citizen-Reported Flood Warning via Augmented Totems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flood warning systems face challenges in data collection, particularly in developing countries, due to high maintenance costs of sensors and limited ability to sense flood levels and communicate effectively with citizens in affected areas.
Innovation Solution
Implementing a system that uses augmented flood information totems, where local residents can report water levels using cell phones or SMS, allowing for automated data collection and warning distribution to registered individuals, with the option to include sensors and communication devices like sirens and loudspeakers for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are deployed for water level data collection, then measurement precision is improved, but device complexity and maintenance cost increase
Solution Approach 1:
The patent implements a citizen reporting system where local residents voluntarily report water levels themselves using mobile phones, eliminating the need for deployed sensors. The system serves itself by leveraging the existing mobile phone infrastructure and citizen awareness rather than requiring complex sensor deployment and maintenance infrastructure.
Solution Approach 2:
The patent replaces the mechanical sensor-based measurement system with an information-based citizen reporting system. Instead of using physical sensors to detect water levels, the system substitutes this with citizens observing and reporting water levels through mobile communications, thereby eliminating the need for complex sensor infrastructure.
2Reliability
If traditional warning systems are used, then warning coverage is improved, but adaptability to mobile populations deteriorates
Solution Approach 1:
The patent implements a dynamic warning system that automatically updates recipient lists based on current population data. The system maintains a database of mobile phone numbers for residents in flood-prone areas and dynamically generates warnings based on real-time flood predictions, ensuring warnings reach the current population even as people move in and out of areas.
Solution Approach 2:
The system incorporates feedback mechanisms where water level reports from citizens trigger automated flood predictions and warning distributions. The system continuously monitors incoming water level data, updates flood risk assessments, and redistributes warnings as needed, creating a closed-loop system that adapts to changing conditions and population movements.
3Productivity
If comprehensive flood monitoring is implemented, then productivity of flood warning system is improved, but loss of information deteriorates due to communication gaps
Solution Approach 1:
The patent uses mobile phones as multi-functional tools that serve both as water level reporting devices and as warning delivery channels. Citizens use the same device to report water levels and to receive flood warnings, eliminating communication gaps and ensuring information reaches those who provide data.
Solution Approach 2:
The system employs an automated information processing platform that acts as an intermediary between citizen reports and warning distribution. This platform receives water level data, processes it through flood prediction algorithms, and automatically distributes warnings to relevant populations, ensuring no information is lost in transmission and enabling scalable operation.
Data Source
AI summary
Techniques for automatically providing flood warnings to individuals are provided. The techniques include receiving a message regarding a water level observed in connection with a totem display at a geographic area, using the message and one or more items of available data to generate a flood level prediction for the geographic area, and sending a flood warning to one or more registered individuals if the flood level prediction for the geographic area exceeds a predetermined threshold.
