Substrate Manufacturing Line Job Verification and Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In substrate manufacturing lines, manual selection of manufacturing job data can lead to errors, such as mixing front and back surfaces or selecting outdated revisions, and changes in manufacturing plans can result in incorrect settings, causing malfunctions or delays, due to the complexity of managing multiple similar data sets and timely notifications.
Innovation Solution
A substrate manufacturing machine and line equipped with a substrate type setting section, a checking section to verify correct settings, a manufacturing condition examination section, and an authorization section to ensure that only correct and condition-satisfied settings proceed with manufacturing, thereby preventing errors and changes in the manufacturing plan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual selection operation is used to set subsequent substrate types, then the operator can flexibly refer to manufacturing plan and select from multiple pieces of manufacturing job data, but there is a high possibility of erroneous selection due to similar names, confusion between front and back surfaces, selection of outdated revisions, or failure to recognize manufacturing plan changes
Solution Approach 1:
The system performs automatic selection of manufacturing job data by itself without requiring operator intervention. The setting section automatically acquires the next substrate type from manufacturing planning data and selects the corresponding manufacturing job data, eliminating human error while maintaining operational flow.
Solution Approach 2:
The manual mechanical selection process is replaced with an automated information processing system. The setting section uses data processing and communication to automatically match substrate types with manufacturing job data, substituting human cognitive and manual operations with automated computational processes.
2Adaptability or versatility
If multiple pieces of manufacturing job data with similar names are provided for selection, then various substrate types can be manufactured, but it becomes difficult to distinguish and select the correct data, leading to setting errors
Solution Approach 1:
The system establishes feedback loops where the setting section continuously acquires manufacturing planning data, compares it with current manufacturing status, and automatically adjusts selections. This feedback mechanism ensures the correct manufacturing job data is selected even when multiple similar data sets exist.
Solution Approach 2:
The setting section acts as an intermediary between manufacturing planning data and manufacturing execution. It processes and matches data automatically, serving as a mediator that prevents direct human exposure to the complexity of distinguishing similar manufacturing job data.
3Loss of information
If the operator is notified of manufacturing plan changes, then the operator can adjust settings, but there is time delay in notification that prevents the operator from recognizing changes in time
Solution Approach 1:
The setting section continuously and automatically monitors manufacturing planning data without interruption. This continuous automated operation eliminates the time delays associated with periodic or manual notification systems, ensuring immediate recognition and response to manufacturing plan changes.
Solution Approach 2:
The system performs preliminary automatic selection of manufacturing job data based on upcoming substrate types before actual manufacturing begins. By proactively acquiring and processing manufacturing planning data in advance, the system prevents setting errors before they occur rather than reacting to changes after notification.
4Productivity
If automated selection function is used to set subsequent substrate types, then selection speed is improved, but the system cannot determine whether the set subsequent substrate types are correct or account for manufacturing plan changes
Solution Approach 1:
The setting section incorporates feedback mechanisms that continuously verify selected manufacturing job data against current manufacturing planning data. This automated verification process maintains high selection speed while ensuring correctness through continuous data comparison and validation.
