Elevator Dispatch System Using Depth Sensing for Passenger Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator systems face inefficiencies in passenger conveyance due to unnecessary stops at floors where no passengers embark or debark, affecting travel and wait times, which impact passenger satisfaction.
Innovation Solution
A passenger conveyance control system utilizing a sensor system with depth sensing technology to track passengers from the waiting area to the elevator car, maintaining passenger identification data until debarkation, and canceling destination requests if passengers change their minds or fail to board, ensuring efficient dispatch and reducing unnecessary stops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the elevator stops at every floor to check for passengers, then no passenger is left behind, but travel time increases and productivity decreases
Solution Approach 1:
The system performs preliminary tracking of passengers from the waiting area through the elevator entrance and maintains identification until debarkation. This preliminary action allows the elevator to proceed directly to the destination without stopping at intermediate floors to verify passenger presence, thereby reducing travel time while ensuring no passenger is left behind.
2Reliability
If the elevator stops at every floor to check for passengers, then no passenger is left behind, but the number of stops increases and productivity decreases
Solution Approach 1:
The system performs preliminary tracking of passengers from the waiting area through the elevator entrance and maintains identification until debarkation. This preliminary action allows the elevator to proceed directly to the destination without stopping at intermediate floors to verify passenger presence, thereby reducing the number of stops and improving productivity while ensuring no passenger is left behind.
3Reliability
If the elevator makes unnecessary stops, then all potential passengers are served, but wait time increases and productivity decreases
Solution Approach 1:
The system uses sensor feedback to continuously monitor passenger presence and location throughout the journey. This feedback mechanism allows the elevator to dynamically adjust its operation, making stops only when actually needed based on real-time passenger information, thereby reducing wait time while maintaining comprehensive service coverage.
Solution Approach 2:
The system performs preliminary tracking of passengers from the waiting area through the elevator entrance and maintains identification until debarkation. This preliminary action allows the elevator to proceed directly to the destination without stopping at intermediate floors to verify passenger presence, thereby reducing wait time while ensuring no passenger is left behind.
4Ease of operation
If traditional destination request systems are used, then passengers can request service, but unnecessary stops occur when passengers change their minds or fail to board
Solution Approach 1:
The system uses sensor feedback to continuously monitor passenger presence and location throughout the journey. This feedback mechanism allows the system to detect when passengers fail to board or change their minds, and automatically cancel destination requests, thereby eliminating unnecessary stops and improving dispatch efficiency while maintaining ease of operation.
Solution Approach 2:
The system automatically tracks and monitors passengers without requiring manual confirmation or intervention. The sensor system self-service monitors passenger presence and automatically manages destination requests, canceling them when passengers fail to board or change their minds, thereby improving dispatch efficiency without adding operational complexity.
Applied Scientific Principles

AI summary
A method of passenger conveyance control includes receiving a destination request; tracking a passenger who entered the destination request while in a waiting area; and canceling the destination request in response to the passenger leaving the waiting area.
