Welded Workpiece Identifier Selection for Clear Traceability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing welding management systems face challenges in efficiently managing identifiers of workpieces produced in welding processes, as they often assign new identifiers for each production machine, complicating traceability and reducing system administrator efficiency.
Innovation Solution
A welding method and identification sign assignment device that select an identifier for a welded workpiece based on a predetermined rule, ensuring efficient management by hiding or disabling identification signs of unselected original workpieces after the welding process, thus simplifying traceability and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a new identifier is assigned each time a workpiece is located in a different production machine, then traceability information can be recorded at each machine, but the identifier management becomes complicated and work efficiency deteriorates
Solution Approach 1:
The system performs preliminary actions by assigning a unique identifier to the workpiece at the very beginning (at the first production machine) and then maintains this identifier throughout the entire production process. This preliminary assignment eliminates the need to create new identifiers at each subsequent machine, thereby preventing information loss while maintaining high work efficiency.
2Loss of information
If multiple identifiers are assigned to the same workpiece for different production machines, then complete production history can be tracked, but identifier management complexity increases
Solution Approach 1:
The unique identifier assigned to the workpiece serves multiple functions throughout the production process. The same identifier is used to track the workpiece at the first production machine, subsequent production machines, and final assembly, eliminating the need for machine-specific identifiers. This universal identifier approach maintains complete production history while significantly reducing management complexity.
3Loss of information
If identification signs of unselected original workpieces are not hidden after welding, then all original workpiece information remains readable, but traceability of the welded workpiece becomes complicated
Solution Approach 1:
The system extracts and preserves the essential traceability information by assigning a unique identifier to the welded workpiece that represents the entire assembly. The identification signs of individual original workpieces are effectively 'taken out' or hidden after welding, as their information is subsumed into the unified identifier of the welded workpiece. This maintains traceability while simplifying the readable information to only what is necessary.
