Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional methods are used to embed information in decorative labels, then the label can be produced, but the information embedding reliability is low and visual appearance is significantly affected
Solution Approach 1:
The patent applies parameter changes by modifying specific parameters of geometric primitives (position, size, color, shape) in the vector graphics representation to embed information. The encoder function systematically varies these parameters within defined modification rules to encode data while maintaining visual similarity to the original label.
Solution Approach 2:
The patent implements local quality by applying modifications only to specific geometric primitives within the label design. The encoder selectively modifies certain elements (lines, curves, shapes) while leaving others unchanged, allowing information embedding in localized regions without affecting the overall visual appearance of the label.
2Loss of information
If complex visual modifications are applied to embed information, then information can be embedded, but the manufacturing process becomes less suitable for mass production
Solution Approach 1:
The patent replaces mechanical/physical modification methods with computational processing. The encoder-decoder system uses software-based vector graphics manipulation to embed and retrieve information, eliminating the need for complex physical label modification processes and enabling efficient digital reproduction for mass production.
Solution Approach 2:
The patent applies preliminary action by pre-defining modification rules and encoder-decoder functions before production. The system prepares the vector graphics representation and encoding parameters in advance, allowing rapid generation of information-embedded labels without time-consuming post-production modifications.
3Loss of information
If existing encoding methods are used, then information can be embedded, but the flexibility in label design is restricted
Solution Approach 1:
The patent implements dynamics by making the encoding system adaptable and configurable. The encoder function can be configured with different modification rules, and the vector graphics representation can be dynamically adjusted to accommodate various label designs, information types, and decoding requirements, providing versatile design flexibility.
Solution Approach 2:
The patent applies universality by creating a general-purpose encoder-decoder system that can handle multiple types of decorative labels, various information formats, and different geometric primitive modifications. The system is designed to work with diverse label designs without requiring design-specific customization.
4Loss of information
If information is embedded in decorative labels, then the label contains data, but the visual appearance changes in a readily discernible manner
Solution Approach 1:
The patent applies preliminary anti-action by pre-defining modification rules that constrain the extent and nature of visual changes. The encoder is configured to make subtle parameter adjustments within acceptable thresholds, preventing readily discernible visual differences while still embedding sufficient information capacity.
