QR Code Document Version Verification via Smart Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in ensuring that end users have access to the correct, latest version of two-dimensional (2D) drawings, leading to potential errors and inefficiencies in manufacturing, construction, and other processes.
Innovation Solution
A computer-based method that uses a non-alphanumeric code, such as a QR code, to identify documents and their versions, allowing users to check remotely if the document they are using is the latest version by scanning the code with a smart device and accessing a remote network location for verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional document version control methods are used, then document management becomes complex and time-consuming, but users can still access document versions
Solution Approach 1:
A non-alphanumeric code (such as a QR code) is generated and attached to the document in advance, containing or linking to version information. This preliminary encoding allows users to instantly verify document versions by scanning the code, eliminating the need for manual version checking processes and significantly reducing verification time while maintaining ease of operation.
2Productivity
If manual version checking processes are used, then users can identify document versions, but the process becomes complex and inefficient
Solution Approach 1:
The manual mechanical process of version verification (comparing version numbers, checking document properties) is replaced with an optical scanning system. Users simply scan the non-alphanumeric code with a smartphone or scanner, and the system automatically retrieves and compares version information from the database, dramatically improving productivity while reducing system complexity.
Solution Approach 2:
Instead of requiring users to access and compare full document versions, a simplified copy of the version information is embedded in the non-alphanumeric code. This allows rapid verification through code scanning alone, improving productivity without requiring complex document access and comparison procedures.
3Reliability
If detailed version information is stored locally, then version tracking is accurate, but storage requirements and system complexity increase
Solution Approach 1:
A centralized database serves as an intermediary between the code and the full version information. The non-alphanumeric code contains only a reference or link to the actual version data stored in the database. This maintains reliable version identification through centralized storage while keeping individual user devices simple, as they only need scanning capability and database access, not local storage of detailed version information.

AI summary
A computer-based method includes reading a non-alphanumeric (e.g., QR or quick response) code from a document that includes substantive information subject to change over time with a code reader of a smart device. The code includes a document identifier that identifies the document and a version indicator associated with the document, and a uniform resource locator for a remote network location where information about the document and any versions is stored. A request is initiated, from the smart device, to check at the remote network location whether the version of the document at issue is a particular version of the document (e.g., the latest version of the document). The smart device receives a response and produces a notification on its display screen indicating whether the document is the particular (or latest) version of the document.
