Vehicle Interval Control for Operator-Adaptive Unmanned Workflows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The variability in operator body size and skill levels leads to inefficient work processes in manufacturing systems where vehicles are operated by unmanned driving, as standard intervals may not accommodate all operators, reducing their efficiency.
Innovation Solution
A control device that acquires operator characteristic information to adjust the interval between vehicles based on body size and proficiency level, using a controller to maintain a target interval that optimizes work efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a standard interval between vehicles is used, then the system is simple to operate, but operators with different body sizes and skill levels experience reduced work efficiency
Solution Approach 1:
The vehicle interval is changed from a fixed standard value to a dynamic value that automatically adjusts based on operator characteristics. The control device acquires operator information and calculates appropriate intervals in real-time, allowing the system to adapt to different operators without manual intervention.
Solution Approach 2:
The system changes the parameter of vehicle interval from a constant standard value to a variable value determined by operator body size and skill level. This parameter adaptation allows the same control system to optimize performance for diverse operators.
2Productivity
If the interval between vehicles is adjusted for each operator, then work efficiency is improved, but the control system becomes more complex
Solution Approach 1:
The control device automatically acquires operator information and determines appropriate vehicle intervals without requiring manual input or complex configuration. The system serves itself by integrating operator data acquisition and interval calculation functions.
Solution Approach 2:
The control device performs multiple functions: it manages vehicle operations, acquires operator information, determines appropriate intervals, and controls vehicle speed and positioning. This multi-functionality consolidates what would otherwise require separate systems.
3Productivity
If vehicles move quickly to reduce process time, then productivity increases, but the risk of collisions between vehicles and operators increases
Solution Approach 1:
The control device continuously monitors operator position and vehicle position, using this feedback to dynamically adjust vehicle speed and interval. This closed-loop control ensures safety while maintaining efficient throughput.
Solution Approach 2:
The system determines the appropriate vehicle interval before vehicles begin movement, based on operator characteristics. This preliminary setup prevents dangerous situations before they occur by establishing safe operating parameters in advance.
