Solution Overview
Problem
During and after natural disasters or accidents, it is challenging to reach accident and disaster sites efficiently, leading to time-consuming and inefficient search techniques using expensive equipment, which can hinder timely and accurate response and recovery efforts.
Innovation Solution
A computer-implemented method that identifies a mobile detection device, requests it to travel to a predetermined location, retrieve location information and supplementary data from an RFID tag, determines the three-dimensional location of the tag, and creates a three-dimensional map incorporating this information to facilitate efficient search and rescue operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual search techniques are used at disaster sites, then search operations can be performed without specialized equipment, but the search process becomes time-consuming and inefficient
Solution Approach 1:
The patent replaces manual mechanical search techniques with an automated mobile detection device that uses RFID technology to automatically detect and retrieve information from tags at disaster sites, significantly improving search efficiency and reducing time loss
Solution Approach 2:
The mobile detection device autonomously navigates to predetermined locations, automatically reads RFID tags, and transmits data without requiring continuous manual operation or expensive specialized equipment, enabling self-service search operations
2Difficulty of detecting and measuring
If expensive equipment is used for search operations, then detection capability is improved, but cost and operational complexity increase
Solution Approach 1:
The patent employs inexpensive RFID tags that can be distributed throughout the environment rather than requiring expensive durable detection equipment, achieving improved detection capability through low-cost, simple devices
Solution Approach 2:
The mobile detection device is designed with multi-functionality, serving as both a navigation unit and RFID reader, thereby reducing the need for multiple specialized expensive devices and simplifying overall equipment complexity
3Measurement precision
If traditional two-dimensional mapping is used, then map creation is simpler, but location precision and spatial understanding are limited
Solution Approach 1:
The patent transitions from traditional two-dimensional mapping to three-dimensional map creation by integrating vertical position data with horizontal coordinates, providing enhanced location precision and spatial understanding of disaster sites
