Autonomous Moving Body Elevator Orientation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous moving bodies face difficulties in smoothly exiting from an elevator car in a short period of time, especially when the exit direction is unknown until the door opens, and adjusting orientation inside the car can lead to collisions with passengers.
Innovation Solution
An autonomous moving body with a determination unit to identify the waiting area, an orientation adjustment unit to align with the exit direction before entering the elevator, and a movement controller to enter the car while maintaining the adjusted orientation, ensuring smooth exit and minimizing passenger disturbance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the autonomous moving body enters the elevator car without adjusting its orientation in advance, then the device complexity is reduced, but the exiting time increases and smoothness of exit deteriorates
Solution Approach 1:
The autonomous moving body adjusts its orientation to match the exiting direction before entering the elevator car. This preliminary orientation adjustment ensures that when the car arrives at the destination floor, the moving body is already positioned and oriented correctly for immediate exit, eliminating the need for time-consuming reorientation inside the car.
2Ease of operation
If the autonomous moving body adjusts its orientation inside the car to align with the exit direction, then the exiting smoothness is improved, but the risk of colliding with passengers increases
Solution Approach 1:
The orientation adjustment is performed outside the elevator car before entry, rather than inside the car. This preliminary action eliminates the collision risk with passengers while still achieving the desired exit alignment, as the moving body enters the car already oriented correctly and maintains that orientation throughout the ride.
3Ease of operation
If the autonomous moving body enters the car without a predetermined orientation, then the ease of entering is improved, but the productivity of the system decreases due to longer exiting time
Solution Approach 1:
The autonomous moving body performs orientation adjustment at the waiting area before entering the car. This preliminary action ensures that the body is optimally positioned for exit without complicating the entry process, as the orientation adjustment occurs in the open waiting area rather than during entry or inside the confined car space.
4Ease of operation
If the autonomous moving body waits in the center of the car, then the ease of operation is improved, but the passenger comfort deteriorates due to feeling of pressure
Solution Approach 1:
The autonomous moving body is positioned in a specific local area of the car (away from the center) based on the exit direction. This localized positioning strategy optimizes both passenger comfort and operational efficiency by placing the moving body in a location that minimizes passenger pressure while maintaining optimal exit alignment.

AI summary
An autonomous moving body includes: a determination unit configured to determine that the autonomous moving body has arrived at a waiting area on a current floor before the autonomous moving body gets on a car of the elevator; an orientation adjustment unit configured to adjust, when the determination unit determines that the autonomous moving body has arrived at the waiting area, an orientation of the autonomous moving body based on an exiting direction from the car on a destination floor; and a movement controller configured to cause, when the car arrives, the autonomous moving body to enter the car while maintaining the orientation adjusted by the orientation adjustment unit.
