Tablet Two-Dimensional Identifier Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing tablets with identifying information, such as QR codes, are complex and prone to damage or manipulation, compromising medicament safety and authentication.
Innovation Solution
A solid dosage form with a two-dimensional identifier, such as a QR code, integrated into the base body using screen printing, ensuring unambiguous authentication and enhanced safety by eliminating the need for separate substrate production and reducing the risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If QR codes are printed onto tablets using inkjet printing or 3D printing, then tablet identification capability is improved, but the identifier can easily be damaged or manipulated and production complexity increases
Solution Approach 1:
The patent merges the identifier directly into the tablet matrix by incorporating colorants or fluorescent substances during the tablet compression process. This integration ensures the identifier becomes an inherent part of the tablet structure, making it resistant to damage or manipulation while eliminating separate printing steps. The identifier and medicinal substance are combined in a single production process, resolving the contradiction between reliability and production complexity.
Solution Approach 2:
The identifier is prepared and integrated into the tablet during the initial compression process rather than being added afterward. By incorporating the identifying colorants or fluorescent substances into the powder mixture before compression, the identifier is established as a fundamental component of the tablet, ensuring its durability and eliminating subsequent printing operations.
2Ease of manufacture
If tablets are punched locally to indicate information, then production process is simple, but information capacity is limited and authentication capability is insufficient
Solution Approach 1:
The patent employs colorants with different absorption spectra or fluorescent substances incorporated into the tablet matrix to encode information. By varying the color, fluorescence intensity, or spectral characteristics at different locations or regions of the tablet, extensive information can be conveyed beyond what simple punching can achieve, while maintaining the simplicity of the compression-based production process.
