Dynamic Display System for Elevator Lobby Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional elevator systems in large buildings face inefficiencies in managing passenger traffic, particularly in dynamically displaying information to users and optimizing elevator car assignments based on real-time passenger locations and requests.
Innovation Solution
A dynamic display system that uses three-dimensional sensors to track users' locations and provide personalized, real-time information, such as directions to their destination, news, weather, and advertisements, on displays that follow the user throughout the building.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional static display systems are used in elevator lobbies, then device complexity is reduced, but information relevance to users deteriorates
Solution Approach 1:
The display system transitions from static to dynamic by continuously updating displayed information based on real-time user location data obtained from mobile devices. The system dynamically assigns elevator cars and updates display content as users move through the building, ensuring information remains relevant without requiring complex reconfiguration of the display hardware itself.
Solution Approach 2:
The system implements feedback loops by continuously monitoring user locations via mobile device GPS or WiFi positioning, comparing this data against elevator car positions and assignments, and automatically updating display information accordingly. This closed-loop feedback ensures displays always show relevant information about assigned elevators and user destinations.
2Productivity
If destination entry systems are implemented, then elevator dispatching efficiency is improved, but user guidance accuracy deteriorates without real-time location tracking
Solution Approach 1:
The system replaces traditional mechanical location tracking methods with electronic positioning technologies. Mobile devices on user hands provide location data through GPS satellites or WiFi triangulation, eliminating the need for complex mechanical tracking infrastructure while achieving high location precision. This substitution enables accurate real-time user location monitoring that feeds into the destination entry system's elevator assignment algorithm.
3Loss of time
If displays continuously update based on user location, then information timeliness is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous updating, the display system employs periodic updates triggered by specific events such as user movement detected via location changes, elevator car arrivals, or assignment changes. This periodic action maintains information timeliness by updating only when necessary, reducing unnecessary energy consumption from constant refresh cycles while keeping users informed of relevant changes.
