Unmanned Vehicle Stop Alignment for Accurate Part Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle production, unmanned vehicles may stop at positions displaced from the intended stop position, leading to improper assembly of parts.
Innovation Solution
A system with a control command unit that adjusts the vehicle's position to a suitable stop position for assembly by transmitting first and second control commands, using sensors and determination units to ensure accurate alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the moving object stops at the first position according to the first control command, then the stopping operation is completed, but the assembly cannot be performed properly due to position deviation
Solution Approach 1:
The determination unit checks whether the first stop position is suitable for assembly, and based on this feedback, the control command unit decides whether to transmit a second control command for position adjustment. This feedback mechanism ensures assembly precision while avoiding unnecessary movements.
Solution Approach 2:
The system performs a preliminary determination of whether the stop position is suitable before attempting assembly. If the position is not suitable, the system prepares and transmits a correction command in advance, preventing assembly errors before they occur.
2Manufacturing precision
If the moving object moves to the second position to correct the stop position, then the assembly can be performed properly, but the production efficiency decreases due to additional movement
Solution Approach 1:
The determination unit provides feedback on whether the first stop position is suitable for assembly. Only when the position is unsuitable does the system transmit a second control command for correction. This selective feedback mechanism maintains high productivity by avoiding unnecessary corrections while ensuring precision when needed.
Solution Approach 2:
The system changes the control parameter from a fixed stop command to a conditional correction command based on the determined position suitability. This dynamic parameter adjustment allows the system to maintain both efficiency and precision by adapting the control strategy to actual conditions.
3Manufacturing precision
If the system transmits a second control command for position correction, then the assembly position accuracy is improved, but the device complexity increases
Solution Approach 1:
The control system is segmented into distinct functional units: a control command unit for transmitting commands, a determination unit for checking position suitability, and a communication unit for data exchange. This segmentation simplifies the overall system architecture while achieving precise position control through coordinated operation of individual modules.

AI summary
The system includes a control command unit configured to transmit to a moving object running by unmanned driving a first control command for stopping the moving object at a first position, and a determination unit configured to determine whether a first stop position at which the moving object has been stopped according to the first control command is a work position suitable for the assembly of the part. When the determination unit determines that the first stop position is not the work position, the control command unit transmits to the moving object a second control command for moving the moving object to a second position where the assembly of the part is performed.
