Unmanned Transfer Device RF Communication for Reduced Working Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The automated material handling system in manufacturing processes, such as for liquid crystal display devices and semiconductor elements, faces inefficiencies due to the need for the unmanned transfer device to stop for extended periods during data communication with manufacturing facilities, limiting overall operation efficiency.
Innovation Solution
A data communication method that allows the unmanned transfer device to perform RF communication for setting and releasing work environments while moving, minimizing stoppage time by decelerating to a stop position, calculating a deceleration section, and adjusting the wireless communication start position to ensure stable communication and efficient data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If optical communication is used for data transmission between unmanned transfer device and manufacturing facility, then communication reliability is improved, but working time increases due to required stoppage
Solution Approach 1:
The patent replaces the mechanical/optical communication system (which requires stopping and precise alignment) with a wireless communication system that transmits data while the unmanned transfer device is moving, thereby eliminating the need for stoppage and reducing working time
Solution Approach 2:
The patent performs data transmission and reception during the movement phase before the carrier work is executed, preparing communication in advance so that no additional stoppage is needed during the actual working process
2Reliability
If the unmanned transfer device stops at the manufacturing facility for data communication, then communication stability is improved, but operation efficiency deteriorates
Solution Approach 1:
The patent substitutes the stop-based optical communication method with continuous wireless communication that operates during movement, maintaining communication functionality without sacrificing operation efficiency
Solution Approach 2:
The patent enables continuous data transmission and reception throughout the movement process, ensuring that communication activities continue without interruption rather than being paused during transit
