Remote-Controlled Moving Object Assembly Skip for Defect Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for unmanned vehicle transportation in assembly areas do not adequately address defects in moving objects, leading to improper assembly during the merging of parts and vehicles.
Innovation Solution
An apparatus comprising a first acquisition unit to detect defects, a parts identification unit to identify corresponding parts, and an instruction unit to execute retraction and skip instructions for defective vehicles, ensuring proper assembly by remote control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If unmanned driving is used to transport moving objects to the assembly area, then transportation efficiency is improved, but defect detection and proper assembly cannot be ensured
Solution Approach 1:
The system performs preliminary defect detection by the first acquisition unit before the moving object reaches the assembly area. When a defect is detected, the instruction unit preemptively issues retraction instructions to remove the defective object and skip instructions to prevent incorrect part assembly, thereby ensuring assembly reliability while maintaining unmanned transportation efficiency
Solution Approach 2:
The system establishes a feedback loop where defect information acquired during unmanned transportation triggers automatic control responses. The instruction unit receives real-time defect data and responds by issuing retraction and skip instructions, creating a closed-loop control system that maintains both transportation efficiency and assembly reliability
2Productivity
If all parts are assembled to moving objects without defect checking, then assembly speed is improved, but incorrect assembly occurs when defects exist
Solution Approach 1:
When a defect is detected in a moving object, the instruction unit issues skip instructions to bypass the assembly process for that specific object. This allows the system to rapidly skip defective items without disrupting the overall assembly flow, maintaining high assembly speed while preventing incorrect assembly of defective objects
Solution Approach 2:
The system extracts defective moving objects from the assembly flow by issuing retraction instructions to remove them from the production line. This separates defective items from the normal assembly process, allowing undetected objects to continue at full speed while defective ones are removed for separate handling

AI summary
An apparatus comprises an acquisition unit that acquires defect information regarding a defect of a moving object that moves on a production line by remote control; a parts identification unit that, in response to acquisition of the defect information, identifies a corresponding part from among a plurality of parts flowing on a parts line, the corresponding part being assembled to a defective moving object, the defective moving object being the moving object with the defect, the parts line merging with the production line at an assembly area where the a part included in the plurality of parts is assembled to the moving object; and an instruction unit that executes a retraction instruction to remove the defective moving object from the production line and an instruction to skip assembly of the corresponding part.
