Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connection is used to transmit test data, then data transmission reliability is improved, but device complexity and ease of operation deteriorate due to connection establishment difficulties
Solution Approach 1:
The patent replaces the mechanical wired connection system with an optical-based QR code system. Test data is converted into visual QR code patterns that can be captured optically by a receiving device, eliminating the need for physical connectors and cables while maintaining data transmission reliability through visual recognition and decoding.
Solution Approach 2:
The patent introduces QR codes as an intermediary carrier between the test device and receiving device. Instead of direct wired or wireless data transmission, the test data is first encoded into QR code visual patterns that serve as a medium, which can then be captured and decoded by the receiving device without requiring direct connection establishment.
2Ease of operation
If wireless transmission is used to transmit test data, then ease of operation is improved, but security and accuracy deteriorate
Solution Approach 1:
The patent replaces wireless electromagnetic signal transmission with optical QR code-based transmission. Instead of transmitting data through vulnerable wireless channels, the data is encoded into static visual QR code patterns that are captured by a camera or image sensor, eliminating wireless transmission security and accuracy issues while maintaining operational ease.
3Measurement precision
If test data is transmitted without compression, then data accuracy is improved, but loss of time increases due to transmission duration
Solution Approach 1:
The patent applies data compression to segment and condense the test data before encoding it into QR code format. By compressing the data, the overall size is reduced while maintaining the essential measurement precision, allowing the compressed data to be encoded into a manageable QR code that can be quickly captured and decoded, thereby reducing transmission time without significant loss of data accuracy.
4Ease of operation
If QR code is used to transmit test data, then ease of operation and security are improved, but device complexity increases due to compression and encryption requirements
Solution Approach 1:
The patent leverages the universality of standard QR code technology and widely available compression/encryption algorithms. By using established, multi-purpose tools and libraries that are already integrated into most modern devices, the system achieves secure and easy data transmission without requiring custom-built complex systems, thereby minimizing the actual increase in device complexity.

AI summary
In some examples, QR code based test data embedding and transmission may include obtaining, by a test data analyzer that is executed by at least one hardware processor, test data based on operation of a test device to measure a parameter associated with an optical fiber. Based on an analysis of the test data, a report that includes the test data may be generated. A quick response (QR) code generator that is executed by the at least one hardware processor may compress the report that includes the test data to generate a compressed report. The QR code generator may generate, based on an analysis of the compressed report, a QR code that includes the compressed report. A display generator that is executed by the at least one hardware processor may generate a display of the QR code that includes the compressed report.
