Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If two-dimensional optical codes are used to carry large amounts of information, then the information capacity is improved, but the device complexity increases due to the need for specialized printing systems and decoding equipment
Solution Approach 1:
The two-dimensional optical code is divided into multiple quadrants, each containing optical cells with geometric shapes. This segmentation allows the code to carry 20 bits of information across 4 quadrants, with each quadrant contributing 5 bits. The segmentation enables mobile devices to capture and decode the code without requiring specialized printing systems or complex dedicated hardware.
Solution Approach 2:
The two-dimensional optical code can be captured and decoded by standard mobile computing devices with cameras, making it universally compatible with existing consumer electronics. The code serves multiple functions: identification, authentication, and information transfer, eliminating the need for specialized printing systems or dedicated decoding equipment.
2Measurement precision
If traditional barcodes and two-dimensional optical codes are used for financial transactions, then the identification accuracy is improved, but the ease of operation deteriorates due to the need for separate payment terminals and internet access
Solution Approach 1:
The two-dimensional optical code enables self-service financial transactions by allowing users to perform payments directly on their mobile devices without requiring separate payment terminals or internet connectivity. The code contains all necessary transaction information that can be read and processed by the mobile device's camera and computational capabilities.
Solution Approach 2:
The patent combines the identification function of barcodes with the authentication function of financial transactions into a single two-dimensional optical code. This merging eliminates the need for separate payment terminals and internet access, as the code integrates both identification and transaction authorization capabilities in one compact format.
3Reliability
If error correction codes are added to mitigate errors in barcodes and two-dimensional optical codes, then the reliability is improved, but the quantity of information decreases due to the overhead of error correction data
Solution Approach 1:
The patent uses geometric shapes and their spatial arrangements within optical cells to encode information, changing the representation parameters from traditional binary sequences to geometric patterns. This allows for efficient use of space, carrying 20 bits of information across 4 quadrants without requiring excessive error correction overhead, as the geometric encoding inherently provides robustness against reading errors.

AI summary
An aspect of the present disclosure provides a method of obtaining information from a two-dimensional optical pattern. An image is captured of the two-dimensional optical pattern, which includes plurality of optical quadrant having plurality of optical cell. Contours of the two-dimensional optical pattern are determined in the image determining locations in two dimensions of plurality of optical quadrant within the contours of the two-dimensional optical pattern. Further, the locations of optical cell placed around the optical quadrant are determined in two-dimensional geometric shape in the optical cell that are spliced apart from each other at predetermined locations in the optical cell with respect to the optical quadrant. The information content of the two-dimensional optical pattern is determined.
