Indoor Navigation System for Emergency Evacuation Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation techniques are ineffective during emergencies in large public spaces like shopping malls or transportation hubs, as users often select incorrect routes due to panic, leading to wasted time during evacuation.
Innovation Solution
A navigation method and apparatus that automatically determine the user's position and form a navigation route based on pre-set functions, such as emergency evacuation, without requiring manual selection of origin and destination, using indoor locating functions and pre-defined navigation rules to quickly provide a safe and time-efficient route.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual selection of origin and destination is used in conventional navigation, then users can customize their route preferences, but navigation time increases and users may select incorrect routes during emergencies due to panic
Solution Approach 1:
The patent applies preliminary action by pre-setting navigation rules for different scenarios (including emergency evacuation routes) before the actual navigation need arises. When an emergency occurs, the system automatically retrieves and executes the pre-configured evacuation route without requiring users to make decisions under stress, thereby ensuring route accuracy and reducing navigation time.
2Adaptability or versatility
If complex user input is required for navigation, then route customization is possible, but user operation becomes difficult during emergency situations
Solution Approach 1:
The system implements self-service by automatically detecting the user's current location, identifying the appropriate evacuation scenario, and generating the navigation route without requiring any user input. The pre-configured navigation rules enable the system to autonomously provide customized evacuation routes based on the detected situation, eliminating the need for complex user operations during emergencies.
3Adaptability or versatility
If all possible means to reach destination are provided, then users have more route options, but users in panic may choose wrong paths or non-shortest routes
Solution Approach 1:
The patent applies local quality by providing different levels of route information based on the specific situation. For emergency evacuation scenarios, the system prioritizes and highlights the optimal evacuation route with clear guidance, while still maintaining the capability to provide alternative routes if needed. This ensures that users receive the most critical navigation information first, improving evacuation efficiency while preserving route option diversity.

AI summary
The present disclosure discloses a navigation method and an apparatus, and a storage medium and a device. The method comprises: obtaining a navigation start instruction for a set function; searching a navigation rule corresponding to the set function and locating a current position of a terminal according to the navigation start instruction; and forming a navigation route according to the current position and the navigation rule. The navigation method provided by the present disclosure, by obtaining a navigation start instruction for a set function, searching a navigation rule corresponding to the set function and locating a current position of a terminal according to the navigation start instruction, forms a navigation route according to the current position and the navigation rule. The navigation rule for the set function is set in advance, therefore, the users does not need to select origin and destination by clicking, or perform other operations, so that the navigation route may be formed quickly and navigation time is saved.
