Solution Overview

Problem

Conventional transfer devices for manufacturing display panels, such as those using inorganic or organic light emitting diodes, lack flexibility in controlling logistics transfer routes and adding or changing control logic, leading to inefficient operations.

Innovation Solution

A transfer device control system that includes a slave computer and a master facility server to manage and control multiple transfer modules, allowing real-time adjustment of transfer paths and logistics schedules through a series, parallel, or mesh structure, using command functions to set driving characteristics and logistics transfer directions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional transfer devices control operation only through preset logic in facility operation server or master control device, then control system is simple, but transfer route cannot be changed and control logic cannot be added

Engineering Contradiction:

Improvetransfer route flexibilityVSAvoidcontrol system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control system is segmented into a master control device that manages overall logistics schedules and slave control boards that control individual transfer devices. This segmentation allows the master device to provide high-level routing instructions while slave devices execute specific transfer operations, enabling route changes without redesigning the entire control system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The control system transitions from static preset logic to dynamic real-time control. The slave control board receives real-time instructions from the master control device based on current logistics schedules and operational status, allowing the transfer routes and control logic to be dynamically adjusted during operation.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If conventional transfer devices use fixed control logic, then control logic is simple, but changing individual control logic is complicated

Engineering Contradiction:

Improvecontrol logic flexibilityVSAvoidcontrol logic modification difficulty

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The slave control board is designed as a universal control unit that can be applied to multiple types of transfer devices (conveyors, robots, lifters, etc.). The board receives standardized control instructions from the master device and can adapt to different device types through software configuration rather than hardware modification, making control logic changes easier.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system replaces fixed mechanical control logic with software-based control instructions transmitted from the master control device. This substitution allows control logic to be modified by updating software programs and databases rather than changing physical control circuits, significantly easing the modification process.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If multiple transfer devices are controlled through preset logic only, then control system is stable, but logistics transfer schedule cannot be adjusted in real time

Engineering Contradiction:

Improvelogistics transfer efficiencyVSAvoidreal-time control complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The slave control board continuously monitors the operational status of transfer devices and feeds this information back to the master control device. The master device uses this real-time feedback to dynamically adjust logistics schedules and reassign transfer routes, optimizing productivity while maintaining manageable control complexity through automated decision-making algorithms.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The master control device pre-calculates multiple logistics schedules and transfer routes based on anticipated workload and device availability. When real-time adjustments are needed, the system selects from pre-prepared alternative schedules rather than calculating new routes from scratch, reducing the computational complexity of real-time control while maintaining high productivity.

Inventive Principle:

AI summary

A transfer device control system includes a linear transfer device including transfer modules of a linear motion guide type, a slave computer setting a transfer path for carriers or logistics by checking an arrangement structure of the transfer modules and controlling a transfer operation of the logistics for each of the transfer modules in real time by checking an operation status of each of the transfer modules, and a master facility server supplying arrangement information of the transfer modules and logistics schedule information for each logistics transfer period to the slave computer.
