Autonomous Mobile Object Release Timing at Route Dividing Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous mobile objects experience waiting time when a dividing element divides the group, causing inefficiencies in their movement.
Innovation Solution
A control system with a dividing element identifying unit and a movement control unit that manages the movement of autonomous mobile objects to reduce waiting time by identifying dividing elements and controlling the movement of subsequent objects to pass through them after a predetermined delay, ensuring they start moving when a predetermined period has elapsed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the dividing element stops at least one subsequent autonomous mobile object to divide the group, then the group is properly divided and preceding objects can pass, but waiting time occurs for the subsequent objects
Solution Approach 1:
The control unit calculates and determines the optimal release timing for subsequent autonomous mobile objects before they reach the dividing element. By preliminarily planning the release schedule based on the dividing element's position and the objects' movement speeds, the system ensures that subsequent objects are released at precisely the right moment to minimize waiting time while maintaining proper group division.
Solution Approach 2:
The system dynamically adjusts the release timing of subsequent autonomous mobile objects based on real-time conditions. The control unit continuously monitors the positions of dividing elements and calculates optimal release times, allowing the release schedule to adapt dynamically to changing conditions rather than using fixed intervals, thereby reducing unnecessary waiting time.
2Stability of the object's composition
If subsequent autonomous mobile objects wait by the dividing element for group division, then proper spacing is maintained, but battery energy is consumed during waiting period
Solution Approach 1:
The control unit preliminarily calculates the optimal release timing for subsequent objects based on their battery status and movement requirements. By determining the release schedule in advance, the system minimizes the duration that objects need to wait at the dividing element, thereby reducing energy consumption during idle periods while maintaining necessary group spacing.
Solution Approach 2:
The system changes the release timing parameter dynamically based on battery status and other conditions. When objects have lower battery levels, the control unit adjusts their release timing to minimize waiting time and energy consumption, while still maintaining proper group division and spacing requirements.
3Productivity
If all autonomous mobile objects move simultaneously from the departure point, then movement efficiency is high, but subsequent objects experience excessive waiting time at dividing elements
Solution Approach 1:
The control unit preliminarily determines the release timing for each subsequent autonomous mobile object based on the position of dividing elements and the objects' movement speeds. By calculating and setting the release schedule in advance, the system ensures that objects are released at optimal intervals, maintaining high movement efficiency while minimizing waiting time at dividing elements.
Solution Approach 2:
The system implements dynamic release timing where subsequent objects are not released at fixed intervals but rather at dynamically calculated times based on real-time conditions. The control unit continuously adjusts the release schedule to optimize the balance between movement efficiency and waiting time reduction, allowing objects to move in a coordinated manner without excessive delays.
