Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If two-dimensional codes are transmitted and stored in graphic forms, then information can be expressed simultaneously through horizontal and vertical directions with large data capacity, but communication resources are occupied more, leading to longer communication elapsed time and higher communication cost
Solution Approach 1:
The patent uses text characters as a simplified copy representation of the two-dimensional code information, allowing the same data to be transmitted in a more compact form. Instead of transmitting the full graphical two-dimensional code image, the system extracts and transmits the encoded text character sequence, which contains the same information but occupies fewer communication resources and less time
Solution Approach 2:
The patent changes the physical form parameter of the code from graphical image format to text character format. This parameter change maintains the data capacity while significantly reducing the resource occupation and transmission time, as text characters require fewer bits to represent compared to graphical images

3Ease of operation
If two-dimensional code images are stored in mobile terminal memory, then codes can be displayed and read when needed, but memory capacity is relatively large, which is hardly acceptable for common mobile terminals with limited memory capacity
Solution Approach 1:
The patent stores text character sequences instead of graphical two-dimensional code images in the mobile terminal. These text character copies contain the same information but occupy minimal memory space, making them suitable for devices with limited memory capacity while still allowing easy display and reading when needed
Solution Approach 2:
The patent changes the storage format parameter from graphical image to text character sequence. This parameter change dramatically reduces the memory capacity requirement while maintaining the functionality of storing, displaying, and reading the code information on mobile terminals with limited memory
4Loss of information
If two-dimensional code images are transmitted through image files, then complete information can be transmitted, but communication resources are occupied more, leading to higher communication cost
Solution Approach 1:
The patent uses text characters as a simplified copy representation of the two-dimensional code information, allowing the same data to be transmitted in a more compact form. Instead of transmitting the full graphical two-dimensional code image, the system extracts and transmits the encoded text character sequence, which contains the same information but occupies fewer communication resources and less time
