Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional bar code configurations are used, then the structure is simple and easy to manufacture, but the data capacity is limited and geometric properties are insufficient for high-data encoding
Solution Approach 1:
The circular bar code is divided into multiple concentric data rings, each containing multiple data cells. This segmentation allows the code to encode large amounts of data (over 4 billion unique identification numbers) by organizing information across multiple rings and cells, resolving the contradiction between data capacity and structural simplicity.
Solution Approach 2:
The invention transitions from traditional linear or rectangular bar code layouts to a circular geometry with concentric rings. This dimensional reorganization enables more efficient use of space and allows for higher data capacity while maintaining a compact form factor suitable for strain gage applications.
2Reliability
If locator rings and orientation cells are added to provide geometric properties, then orientation recognition and data recovery are enhanced, but the device complexity increases
Solution Approach 1:
Locator rings and orientation cells are pre-positioned within the circular bar code structure to establish reference frames before data reading occurs. These features enable the imaging apparatus to automatically locate and orient the code, ensuring reliable data recovery even when the code is distorted by non-linear strain, thus improving reliability without requiring complex post-processing.
3Quantity of substance
If multiple concentric data rings with data cells are implemented, then the encoding capacity for unique identification numbers increases to over 4 billion, but the manufacturing precision requirements increase
Solution Approach 1:
The invention uses variable parameters including the number of concentric rings, the number of data cells per ring, and the radial positioning of these elements to achieve over 4 billion unique identification numbers. By adjusting these parameters, the system can encode high-capacity data while accommodating variations in manufacturing precision through the flexible circular geometry design.
4Adaptability or versatility
If radially-extending gaps are introduced to divide the circular bar code into segments, then the bar code can accommodate non-linear strain measurement, but the structural integrity and continuity are reduced
Solution Approach 1:
The circular bar code is divided into segments by radially-extending gaps, allowing each segment to independently accommodate non-linear strain deformation. This segmentation enables the code to remain readable even when the underlying structure undergoes significant deformation, as each segment can be independently located and decoded using the locator rings and orientation cells.

AI summary
A segmented circular bar code is made-up of inner and outer locator rings, one or more data rings, two large orientation cells, an even number of radially-extending gaps dividing the bar code into a corresponding number of segments, and gap locator cells straddling each radially-extending gap. Each of the locator rings and the data rings is circular and has a finite width. All rings are concentric and there is no circumferential space between the rings.
