Mobile Object Conveyance Control for Changing Stop Positions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing systems for vehicle conveyance do not adequately address the issue of changing stop positions due to processing delays, progress of other vehicles, or worker intervention, leading to inefficiencies and potential damage to vehicles.
Innovation Solution
A control system that identifies the stop position of a mobile object on a conveying part using control information and obstacle information, and generates a control command to ensure the mobile object enters the conveying part appropriately, even if the stop position changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the stop position is determined before the mobile object enters the conveyance apparatus, then the control system can prepare the conveyance process in advance, but the stop position may change after entry due to processing delays, progress of other mobile objects, or worker intervention, leading to inefficiency and potential damage
Solution Approach 1:
The control system dynamically updates the stop position based on real-time information from detectors during the conveyance process. Instead of using a fixed predetermined stop position, the system continuously adjusts the stop position according to the actual states of other mobile objects and processing conditions, ensuring both accuracy and efficiency.
Solution Approach 2:
The system employs detectors to monitor the actual positions and states of mobile objects during conveyance and feeds this information back to the control unit. This feedback mechanism allows the control system to identify and adjust to changes in stop position, preventing inefficiency and potential damage from position mismatches.
2Ease of operation
If the system uses a fixed predetermined stop position, then the control system is simple to operate, but it cannot adapt to changing conditions such as processing delays or progress of other vehicles, causing inefficiency
Solution Approach 1:
The control system automatically adjusts the stop position based on information detected during the conveyance process without requiring manual intervention. The system serves itself by using its own detectors to monitor conditions and make real-time adjustments, maintaining ease of operation while improving adaptability.
Solution Approach 2:
The control system transitions from a static predetermined stop position to a dynamic stop position that adapts to changing conditions. This dynamic adjustment is achieved through continuous monitoring by detectors and automatic updates by the control unit, preserving operational simplicity while enhancing adaptability.
3Adaptability or versatility
If the stop position changes after the mobile object has entered the conveyance apparatus, then the system can adapt to processing delays and progress of other mobile objects, but the mobile object may be damaged or the conveyance process interrupted
Solution Approach 1:
The control system identifies and determines the stop position before the mobile object fully enters the conveyance apparatus. This preliminary determination allows the system to prepare for potential position changes and adjust accordingly, preventing damage to the mobile object while maintaining adaptability to processing state changes.
Solution Approach 2:
The detectors continuously monitor the conveyance process and provide feedback to the control unit, enabling real-time adjustment of the stop position. This feedback mechanism ensures that the mobile object is not damaged by sudden position changes while allowing the system to adapt to processing delays and progress of other mobile objects.
