Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display device manufacturing processes face challenges in reducing setting time due to inefficiencies in controlling the positions of multiple motors used in the manufacturing process.
Innovation Solution
A motor position control system and method that utilizes a central server and motor position control device to manage and control the positions of multiple motors based on information from a source table and job table, calculating values and selecting motors to optimize their positions, with real-time adjustments for alignment and attachment accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple motors are controlled sequentially for manufacturing different display devices, then manufacturing flexibility is improved, but setting time increases
Solution Approach 1:
The system pre-calculates position values for multiple motors based on device information received from the central server before actual manufacturing begins. By preparing motor position data in advance using source tables and job tables, the system eliminates time-consuming calculations during the manufacturing process, thus reducing setting time while maintaining the ability to handle different display devices.
Solution Approach 2:
The system dynamically adjusts motor positions based on calculated values that are specific to each display device being manufactured. The controller selectively controls only the motors that require position adjustment based on the calculated values, adapting the control process to the specific manufacturing needs while minimizing unnecessary motor movements and reducing overall setting time.
2Manufacturing precision
If all motors are controlled for every manufacturing task, then positioning accuracy is improved, but system complexity increases
Solution Approach 1:
The system applies different control strategies to different motors based on their specific requirements. The controller selectively controls only those motors for which calculated position values are non-zero, while leaving other motors unchanged. This localized control approach maintains positioning accuracy for motors that need adjustment while simplifying the overall control process by excluding unnecessary motor adjustments.
Solution Approach 2:
The system uses calculated values derived from source tables and job tables to determine the necessary position adjustments for each motor. By changing only the position parameters of motors that require adjustment (those with non-zero calculated values) and maintaining other parameters unchanged, the system achieves precise positioning while reducing control complexity.
