Engineering Contradiction Analysis
1Reliability
If two-dimensional codes are transmitted and stored in graphic forms, then the codes can be visually displayed and recognized, but communication resources are occupied more, communication time is longer, communication cost is higher, and memory capacity is larger
Solution Approach 1:
The patent changes the representation parameter of two-dimensional codes from graphic form to text form. By encoding the two-dimensional code data as text strings instead of images, the communication efficiency is improved while maintaining the ability to display and recognize the codes. This parameter change reduces communication time and resource consumption without sacrificing recognition accuracy.
2Reliability
If two-dimensional codes are transmitted and stored in graphic forms, then the codes can be visually displayed and recognized, but communication cost is higher
Solution Approach 1:
The patent changes the representation parameter of two-dimensional codes from graphic form to text form. By encoding the two-dimensional code data as text strings instead of images, the communication efficiency is improved while maintaining the ability to display and recognize the codes. This parameter change reduces communication time and resource consumption without sacrificing recognition accuracy.
3Ease of operation
If two-dimensional code images are stored in mobile terminal memory, then the codes can be displayed and read when needed, but memory capacity is relatively large
Solution Approach 1:
The patent changes the storage format parameter of two-dimensional codes from image files to text strings. By storing the code data as compact text representations instead of graphical images, the memory capacity required is significantly reduced while maintaining the ability to display and retrieve codes for reading when needed.
4Adaptability or versatility
If two-dimensional code images are transmitted through communication networks, then the codes can be received and transmitted between devices, but many mobile phones cannot receive and transmit them due to device and network limitations
Solution Approach 1:
The patent changes the transmission format parameter of two-dimensional codes from image files to text strings. By transmitting the code data as text instead of images, compatibility with various mobile phones and communication networks is improved, as text transmission is more universally supported. This format change enhances transmission reliability across different devices and network conditions.
