Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional black and white barcodes are used, then manufacturing simplicity is maintained, but detection accuracy deteriorates in certain environments
Solution Approach 1:
The patent changes the color parameters of the barcode from traditional black and white to multiple colors selected from environment-specific color palettes. This parameter change allows the barcode to adapt to different environmental conditions, improving detection accuracy by ensuring sufficient contrast between barcode elements and the background environment.
Solution Approach 2:
The patent implements dynamic adaptation by selecting different color schemes based on the specific environment. The barcode generation process dynamically chooses colors from predefined palettes that are optimized for particular environmental conditions, making the detection system more robust across varying contexts without requiring manual recalibration.
2Loss of information
If multiple color channels are used in matrix barcode, then information capacity increases, but device complexity increases
Solution Approach 1:
The patent transitions from traditional 2D matrix barcodes to 3D layered barcodes that incorporate multiple color channels and depth information. This dimensional expansion allows encoding of additional information layers, effectively increasing information capacity by utilizing the third dimension (depth/layering) rather than merely increasing planar complexity.
Solution Approach 2:
The patent employs composite color structures combining multiple color channels (e.g., cyan, magenta, yellow, black, plus fluorescent and infrared layers) to encode information. This composite approach increases information capacity by utilizing the interactive properties of different color layers, where combinations of layers can represent additional data states beyond what single colors can provide.
3Reliability
If environment-specific color palettes are used, then detection reliability improves, but manufacturing complexity increases
Solution Approach 1:
The patent performs preliminary action by pre-defining multiple color palettes, each optimized for specific environmental conditions (e.g., forest, urban, desert environments). During barcode generation, the system automatically selects the appropriate pre-defined palette based on the target environment, eliminating the need for complex real-time color optimization and simplifying the manufacturing process while maintaining high detection reliability.
Solution Approach 2:
The patent systematically varies color parameters across different barcode instances based on environmental requirements. By establishing predefined color palettes with specific chromaticity coordinates and luminance values for different environments, the system achieves reliable detection across varying conditions while maintaining manufacturing simplicity through standardized color selection processes.
