Automatic Elevator Calling via Wireless Signal Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems require manual operation, which can be difficult for passengers with disabilities or those carrying items, leading to ineffective elevator calling and reduced user experience.
Innovation Solution
An automatic elevator calling system using wireless signals between a mobile terminal and modules in the elevator car and landing area, determining passenger movement by changes in signal strength and direction, allowing for hand-free operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual button pressing operation is used, then the elevator calling operation can be completed, but it becomes difficult for passengers carrying items or unable to walk freely
Solution Approach 1:
The system uses the passenger's own mobile terminal to automatically detect their presence and trigger elevator calling without requiring manual button pressing. The mobile terminal serves itself to initiate the elevator request based on detected movement patterns.
Solution Approach 2:
The mechanical button pressing operation is replaced by an automatic wireless signal-based detection system. The system substitutes the manual mechanical interaction with automated sensor detection and wireless communication between the mobile terminal and elevator control system.
2Ease of operation
If automatic elevator calling operation using wireless signals is implemented, then hand-free operation is enabled, but ineffective elevator calls may occur due to uncertainty of passenger action or movement
Solution Approach 1:
The system performs preliminary detection of passenger movement into the elevator lobby area before triggering the elevator calling function. By detecting movement in advance and confirming the passenger has entered the service area, the system ensures the calling action is appropriate and timely.
Solution Approach 2:
The system continuously monitors wireless signal strength changes to detect passenger movement and provides feedback to determine when to activate or cancel elevator calling requests. This feedback mechanism allows the system to adjust based on real-time passenger behavior.
3Extent of automation
If wireless signal strength monitoring is used to detect passenger movement, then automatic detection of passenger entering elevator lobby is enabled, but system complexity increases
Solution Approach 1:
The mobile terminal's existing wireless communication capabilities are utilized for dual purposes: normal communication functions and elevator presence detection. This multi-functional use reduces the need for dedicated specialized hardware.
Solution Approach 2:
The wireless signal acts as an intermediary carrier that conveys information about passenger presence and movement. By monitoring changes in signal strength of existing wireless communications, the system indirectly detects passenger movement without requiring direct physical sensors.
