Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional manual processing of printed documents for the Production Part Approval Process (PPAP), Part Submission Warrant (PSW), Product Change Notification (PCN), End-of-Life (EOL), Customer Containment Rules (CCR), and Bill of Material (BOM) in the automotive industry is prone to errors, time-consuming, and inefficient, leading to increased manufacturing errors and logistics inefficiencies.
Innovation Solution
The use of QR codes to encode and automate the processing of information typically found in these documents, allowing mobile devices to scan and extract data, compare parameters, and link to additional information stored on servers, thereby streamlining the manufacturing process and improving traceability and logistics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual processing of printed documents is used for PPAP, PSW, PCN, EOL, CCR, and BOM, then human operators can review and interpret the information, but the process is prone to errors, time-consuming, and inefficient
Solution Approach 1:
The patent replaces manual mechanical processing of documents with automated optical scanning and digital image recognition systems. QR codes and barcodes are scanned to automatically extract and process manufacturing parameters, eliminating manual reading and data entry while reducing errors and increasing processing speed simultaneously
Solution Approach 2:
The patent uses QR codes and barcodes as digital copies of manufacturing information that can be rapidly scanned and processed. Instead of manually reading printed documents, the system creates and processes digital replicas of the information encoded in these machine-readable formats, enabling automated extraction and comparison of parameters
2Ease of operation
If manual processing of documents is used, then flexibility in reviewing information is maintained, but manufacturing errors increase and logistics inefficiencies occur
Solution Approach 1:
The patent implements automated feedback loops where scanned QR codes and barcodes provide real-time data about manufacturing parameters. The system automatically compares extracted parameters against specifications, provides immediate feedback on compliance, and triggers alerts for discrepancies, thereby maintaining operational flexibility while eliminating manual errors
Solution Approach 2:
The patent replaces manual document review with automated image scanning and digital processing systems that maintain flexibility through programmable parameters while eliminating human error in information extraction and comparison
3Productivity
If QR codes and barcodes are used to encode manufacturing information, then data extraction and comparison are automated, but the initial implementation complexity increases
Solution Approach 1:
The patent employs universal QR codes and barcodes that can encode multiple types of manufacturing information (parameters, specifications, traceability data) in a single standardized format. This multi-functional approach allows one scanning system to handle diverse information types, reducing overall system complexity despite the automation capabilities
Solution Approach 2:
The patent uses QR codes and barcodes as intermediary elements between physical manufacturing components and digital information systems. These intermediaries encode complex manufacturing data in compact, scannable formats that bridge the physical and digital domains, simplifying the interface between manufacturing processes and information management systems
4Loss of time
If automated scanning and data extraction is implemented, then processing time is reduced, but the initial setup and integration time increases
Solution Approach 1:
The patent implements QR codes and barcodes during the product design and manufacturing setup phase, encoding all necessary parameter information in advance. This preliminary encoding of data eliminates the need for time-consuming manual data entry during production, as the information is already prepared in machine-readable format for rapid scanning and extraction

AI summary
A method includes: scanning a first QR code on a first physical object to obtain first parameters, wherein the first parameters include specifications for making a product using a manufacturing process, and the specifications include at least one material used to build the product. The method further includes scanning a second QR code on a second physical object to obtain second parameters, wherein the second parameters correspond to the manufacturing process; comparing, by a computing device, the first parameters and the second parameters; based on comparing the first parameters and the second parameters, determining whether the first object corresponds to the second object; and in response to determining that the first object corresponds to the second object, building the product using the at least one material.
