Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for identifying and authenticating medication pills are inadequate, as they are easily replicable, require precise surface alignment, and are vulnerable to damage or occlusion, leading to ineffective counterfeiting prevention and medication errors.
Innovation Solution
A fractal-based identification system is implemented, where a fractal pattern is printed onto medication pills, allowing for robust and secure identification through computer vision, which is resilient against orientation, occlusion, and damage, with varying levels of security achieved by different fractal dimensions and imaging resolutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional identification methods (barcodes, serial numbers) are used on medication pills, then the identification system is simple to implement, but the system is easily replicated and vulnerable to counterfeiting
Solution Approach 1:
The patent transforms the identification approach by changing from simple alphanumeric parameters (barcodes, serial numbers) to fractal geometric parameters. The fractal patterns encode multiple identification parameters within their geometric structure, making them mathematically complex to replicate but visually simple to implement. This resolves the contradiction by increasing reliability through mathematical complexity while maintaining ease of implementation.
Solution Approach 2:
The patent combines multiple identification functions into a single fractal pattern structure. The fractal simultaneously serves as a unique identifier, an anti-counterfeiting mechanism, and an orientation reference system. This composite approach increases reliability by integrating multiple security functions while avoiding the complexity of implementing separate systems for each function.
2Measurement precision
If precise surface alignment is required for identification markings, then the identification accuracy is high, but the manufacturing process becomes complex and time-consuming
Solution Approach 1:
The patent employs asymmetric fractal patterns that inherently encode orientation information within their geometry. The fractal's asymmetric structure allows the identification system to determine pill orientation automatically without requiring precise alignment during printing. This resolves the contradiction by maintaining high identification accuracy through the fractal's intrinsic geometric properties while simplifying the manufacturing process.
Solution Approach 2:
The fractal pattern performs self-alignment and self-orientation functions. The identification system automatically determines the correct orientation and position of the fractal on the pill surface without requiring external alignment fixtures or complex positioning mechanisms. This eliminates the need for precise surface alignment during manufacturing while maintaining high identification accuracy.
3Reliability
If traditional identification markings are used, then the printing process is simple, but the markings are vulnerable to damage or occlusion
Solution Approach 1:
The fractal pattern exhibits self-similarity across multiple scales, with smaller fractal structures nested within larger ones. This nested structure ensures that even if portions of the fractal are damaged or occluded, the remaining portions retain sufficient geometric information for identification. The patent leverages this nested property to achieve robustness against damage and occlusion while using relatively simple fractal generation algorithms.
4Reliability
If high security levels are implemented through complex identification systems, then counterfeiting is prevented, but the system becomes difficult to operate and access
Solution Approach 1:
The patent implements a tiered fractal dimension system where different levels of fractal complexity provide different security levels. Basic fractal patterns provide sufficient security for general use, while more complex higher-dimensional fractals provide enhanced security when needed. This allows the system to maintain high security capabilities while keeping the default operation simple and accessible, resolving the contradiction between security and ease of use.

AI summary
A method and system for reading an identifier from an object having a portion of a repeating image imparted thereon. The system preferably includes an imaging apparatus for imaging a portion of the repeating image from the object, the repeating image repeating in the direction of continuous travel of one or more objects through a printing location, at least the portion of the repeating image being printed to each of a plurality of objects, including the object, as the plurality of objects reach the printing location. The system further preferably includes a comparator for comparing one or more expected attributes of the imaged repeating image with one or more corresponding actual attributes of the imaged repeating image.
