Elevator Car Robot Rearrangement for Correct Alighting Order
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems for robots cannot rearrange autonomous mobile bodies in the car, leading to inefficiencies when a robot boards at a different floor from the destination floors of other robots, resulting in improper alighting order.
Innovation Solution
An elevator system with an operation control unit, target selection unit, alighting order determination unit, and rearrangement instruction unit that selects and rearranges autonomous mobile bodies based on their destination floors, ensuring they alight in the correct order by transmitting and implementing the determined alighting order.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If robots are conveyed using an existing elevator system without rearrangement capability, then the system structure remains simple, but the robots cannot be arranged in proper alighting order when a robot boards at a different floor from destination floors
Solution Approach 1:
The control unit determines the optimal boarding positions for robots before the elevator car departs from each floor. By calculating and assigning target positions in advance based on destination floors and current car layout, the system ensures robots are properly arranged for efficient alighting order without requiring complex real-time rearrangement mechanisms during transit.
Solution Approach 2:
The control unit receives information from detection units about robot positions, destination floors, and car status, then continuously adjusts boarding instructions and rearrangement commands. This feedback loop enables the system to adapt to changing conditions and maintain optimal robot arrangement throughout the elevator operation cycle.
2Productivity
If robots are conveyed without position rearrangement capability, then the elevator system operates smoothly, but productivity decreases when multiple robots need to alight at different floors
Solution Approach 1:
The control unit pre-calculates and assigns optimal boarding positions for each robot based on their destination floors and the current arrangement of robots in the car. This preliminary positioning ensures that when the elevator stops at intermediate floors, robots can alight in the correct sequence without requiring time-consuming rearrangements during transit or at each stop.
Solution Approach 2:
The system dynamically adjusts robot positions within the car based on real-time information about destination floors and current car occupancy. The control unit continuously optimizes the arrangement of robots to minimize travel time and maximize alighting efficiency, adapting the configuration as robots board and alight at different floors.

AI summary
An elevator system that allows a plurality of autonomous mobile bodies to be rearranged in an alighting order in a car. The elevator system includes processing circuitry to move and stop an elevator car based on information indicating destination floors transmitted from autonomous mobile bodies, to select an autonomous mobile body in the car and an autonomous mobile body that will board the car as targets to be rearranged. The processing circuitry is further to determine an alighting order of the autonomous mobile bodies to be rearranged based on the destination floor of each of the autonomous mobile bodies to be rearranged, and to transmit information indicating the alighting order to each of the autonomous mobile bodies to be rearranged so that the autonomous mobile bodies are arranged one by one in the alighting order.
