Subassembly Quality Data Coupling via Barcode Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current manufacturing processes lack a method to link quality data of subassemblies built offline with the final product assembly, which is a challenge in vehicle assembly operations where subassemblies are manufactured separately and later integrated into the main assembly line.
Innovation Solution
A method involving generating quality control data for subassemblies, printing it as a 2D barcode, attaching it to the subassembly, and coupling this data with the main product assembly's ID using a controller, allowing for quality standard checks and bypass operations if necessary, ensuring accurate data association and integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If subassemblies are manufactured offline separately and transferred in batches to the main assembly line, then manufacturing efficiency and flexibility are improved, but the ability to track and link quality data of subassemblies with the final product assembly deteriorates
Solution Approach 1:
The patent applies preliminary action by generating and attaching quality control data barcodes to subassemblies during offline manufacturing before they are transferred to the main assembly line. This ensures that quality data is captured and preserved at the subassembly level, enabling later linkage when the subassembly is installed into the final product assembly.
Solution Approach 2:
The patent uses a barcode as an intermediary carrier that contains quality control data. The barcode is attached to the subassembly and later scanned at the main assembly line, serving as a mediator that bridges the offline subassembly manufacturing process with the online final assembly process, enabling data linkage despite the batch transfer disconnect.
2Measurement precision
If quality control data is recorded for each subassembly, then quality monitoring capability is improved, but the complexity of linking subassembly data with main assembly data increases
Solution Approach 1:
The patent uses a barcode as a simplified copy or representation of the quality control data. Instead of managing complex digital data structures and linkage systems, the quality data is encoded into a barcode format that can be easily scanned and processed, reducing the complexity of data linkage while maintaining precise quality monitoring capability.
3Reliability
If all quality data is recorded and tracked, then quality control completeness is improved, but the time and resources required for data management increase
Solution Approach 1:
The patent extracts the essential quality control data from the complex data management system and encodes it into a compact barcode format. This extraction approach captures the critical quality information needed for tracking and linkage while eliminating unnecessary data management overhead, reducing the time and resources required for data management while maintaining quality control completeness.
Data Source
AI summary
A method and apparatus couples quality control data generated during the manufacture of a subassembly of components with at least a unique main product assembly identification number and the quality control data of the main product at the time of installation of a subassembly to the main product assembly. The subassembly quality control data and the main product assembly quality control data and unique product identification are stored.
