Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for controlling automatic conveyance vehicles and elevators do not efficiently utilize all relevant information, leading to inefficient movement and potential operational issues.
Innovation Solution
A lifting and lowering movement control system that acquires and utilizes lifting and lowering relevant information to set optimal movement paths and control speeds for automatic conveyance vehicles, including features like weight management and elevator selection based on article type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If only object detection sensor information is used for elevator control, then the system is simple, but the movement efficiency of automatic conveyance vehicles is insufficient
Solution Approach 1:
The control section acquires lifting and lowering relevant information (elevator position, floor information, operation status) in advance before the automatic conveyance vehicle arrives at the elevator. This preliminary information acquisition enables the system to determine an optimal movement path and adjust vehicle speed proactively, improving movement efficiency without requiring complex real-time decision-making systems.
Solution Approach 2:
The system continuously monitors lifting and lowering relevant information from the elevator and uses this feedback to dynamically adjust the movement path and speed of the automatic conveyance vehicle. This feedback mechanism enables efficient coordination between vehicle movement and elevator operation, resolving the contradiction between simplicity and efficiency.
2Loss of time
If the automatic conveyance vehicle waits for elevator arrival without path optimization, then the control is simple, but time is wasted
Solution Approach 1:
The control section determines the movement path to the elevator in advance based on acquired lifting and lowering relevant information, rather than waiting passively. This preliminary path determination reduces waiting time by having the vehicle ready to move immediately when the elevator becomes available.
Solution Approach 2:
The movement path is not fixed but dynamically determined based on current elevator status and vehicle position. The control section adjusts the path in real-time according to changing conditions, optimizing the waiting time without requiring overly complex predetermined routing systems.
