Wireless Elevator Dispatch via Pushed Web Page
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In elevator dispatching systems, passengers face difficulties in timely requesting elevator service when a large number of people are gathered at a particular floor due to the static nature of destination entry devices.
Innovation Solution
Implementing a wireless transmitter/receiver system that allows passengers to use web-enabled devices to join a network, push a web page to enter service requests, and communicate these requests to a group controller for elevator dispatching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If static destination entry devices (call buttons, key pads) are used at each floor, then the system structure is simple and reliable, but passengers cannot timely request elevator service when a large number of people are gathered at a particular floor
Solution Approach 1:
The patent replaces the mechanical button-based destination entry system with a wireless communication system. Passengers use wireless devices (smartphones, tablets) to communicate with the elevator dispatching system via wireless signals, eliminating the need for physical call buttons and key pads. This substitution enables faster service requests during peak periods while maintaining system reliability.
Solution Approach 2:
The patent makes the destination entry system universal by allowing any wireless device capable of web browsing to access the elevator service request function. Instead of requiring specialized hardware at each floor, the system can be accessed through standard web browsers on smartphones, tablets, and laptops, greatly increasing accessibility and capacity during peak gatherings.
2Ease of operation
If specialized software is required on wireless devices to access the elevator system, then the system can maintain security and control, but passengers must install and use complex software instead of simple web browsers
Solution Approach 1:
The patent introduces a web server as an intermediary between the elevator dispatching system and wireless devices. The server hosts a web page that acts as a mediator, allowing passengers to access the system through standard web browsers without installing specialized software. This intermediary layer maintains security and control while simplifying operation for passengers.
3Productivity
If a large number of passengers are gathered at a particular floor, then the elevator demand increases, but the static destination entry devices become difficult to use in a timely manner
Solution Approach 1:
The patent transitions the destination entry function from a two-dimensional floor-based button system to a three-dimensional wireless communication system that operates across the entire building. Wireless devices can communicate with the dispatching system from any location, allowing passengers to request service without being constrained by physical proximity to call buttons, thereby increasing handling capacity during peak periods.

AI summary
A method for wireless destination entry in an elevator dispatching system, the elevator dispatching system including a wireless transmitter/receiver (T/R) includes receiving a request to join a network of the T/R from a wireless device; pushing a web page from the T/R to the wireless device; receiving a service request by the T/R from the wireless device via the web page; communicating the service request from the T/R to a group controller; and dispatching an elevator car by the group controller to service the service request is provided. An elevator dispatching system and a computer program product including a computer readable storage medium contain computer code that, when executed by a computer, implements a method for wireless destination entry in an elevator dispatching system, the elevator dispatching system including a wireless transmitter/receiver, are also provided.
