Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual handling of jumbo rolls is used for loading and unloading at electrode facilities, then workers can directly handle the rolls, but work efficiency is reduced and safety accidents may occur due to manual labor and rolling issues
Solution Approach 1:
The patent replaces manual mechanical handling with an automated guidance vehicle system that transports jumbo rolls. The vehicle autonomously navigates to loading/unloading positions and performs material handling operations, eliminating the need for workers to manually carry or handle rolls, thereby improving efficiency and preventing safety accidents
Solution Approach 2:
The guidance vehicle is equipped with autonomous navigation capabilities including sensors, controllers, and communication systems that enable it to independently determine its position, plan routes, and execute transportation tasks without continuous human intervention, allowing the system to serve itself in the transportation process
2Manufacturing precision
If EPC snaking correction is used for securing processing quality, then electrode positioning is improved, but automatic docking of the transportation vehicle to the production facility becomes difficult
Solution Approach 1:
The patent implements a dynamic coordinate adjustment mechanism where the guidance vehicle's reference coordinate system is automatically updated based on real-time position information received from the EPC system. This allows the vehicle to adapt its docking target coordinates dynamically as the EPC makes snaking corrections, enabling automatic docking to maintain despite the moving target position
Solution Approach 2:
The system establishes a feedback loop where the guidance vehicle continuously receives position information from the EPC system about the current electrode position, and the vehicle's controller adjusts its docking coordinates based on this feedback. This closed-loop control enables the vehicle to automatically track and dock with the EPC-corrected position

AI summary
An automatic transportation control method includes moving, by an automatic guidance vehicle, to a first node which is an initial reference location according to an instruction from an automatic transportation control apparatus; moving, by the automatic guidance vehicle, to a second node which is a stand-by location before entering a production facility from the first node; moving, by the automatic guidance vehicle, to a third node for docking to the production facility from the second node; and receiving, by the automatic guidance vehicle, the changed location coordinate value of the second node from the automatic transportation control apparatus, and traveling based on the changed location coordinate value of the second node when the second node is changed according to a work location change of the production facility.
