Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If visual indicator methodology is used for test results, then ease of understanding for individual tests is improved, but accuracy of recording and communication for mass testing deteriorates
Solution Approach 1:
The patent uses optical identifiers (barcodes, QR codes) as machine-readable copies of test result information. Instead of manually recording visual indicators, the system creates an optical copy that can be automatically scanned and transmitted, eliminating manual transcription errors while preserving the simplicity of visual test interpretation.
Solution Approach 2:
The patent replaces the manual mechanical process of recording visual indicators with an automated optical scanning system. The optical identifier on the test device allows automated data capture and transmission, substituting human manual recording with machine-based optical recognition and electronic data transfer.
2Measurement precision
If centralized health surveillance systems are used, then accuracy of case reporting is improved, but accessibility in developing countries and for home testing deteriorates
Solution Approach 1:
The patent creates a universal system where the same optical identifier technology works across multiple platforms and communication methods. The test device with optical identifier can report results through various channels (internet, SMS, telephone), making the system universally accessible regardless of location or technological infrastructure while maintaining accurate data collection.
Solution Approach 2:
The optical identifier serves as an intermediary that bridges the gap between simple home testing and complex surveillance systems. It enables test results from any location to be automatically captured and transmitted through multiple possible communication channels, acting as a universal interface between the user and the surveillance infrastructure.
3Measurement precision
If individual patient tracking is implemented, then accuracy of correlating test results with patients is improved, but privacy protection deteriorates
Solution Approach 1:
The patent uses de-identified optical identifiers that capture test result information without copying or transmitting personal identity data. The system creates an optical record of the test outcome that can be tracked and reported while deliberately excluding personally identifiable information, thus protecting patient privacy while maintaining result accuracy.
4Speed
If rapid testing is performed, then speed of diagnosis is improved, but complexity of result reporting for surveillance deteriorates
Solution Approach 1:
The test device performs self-reporting through its optical identifier. Instead of requiring users to manually report results or complex data entry processes, the device automatically provides its test result information through the optical code, which can be scanned and transmitted without user intervention. This eliminates reporting complexity while maintaining rapid test delivery.

AI summary
A method for facilitating epidemiologic surveillance for a target disease such as Covid-19 includes a step of using an optical identifier such as a barcode or a numerical code to rapidly report de-identified test results to a central database. A rapid test device may be based on a direct flow point-of-care device comprising a porous membrane with at least one recombinant antigen applied thereto and procedural control. The recombinant antigen may comprise an epitope for detecting the target disease marker. The first optical identifier may be applied to the device and facilitate remote communication of the test results without the use of any specialized equipment.
