Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional POCT readers are used to capture and analyze test results on-site, then testing efficiency is improved, but privacy concerns arise and device cost increases
Solution Approach 1:
The patent extracts the analysis function from the local POCT device and relocates it to a remote server. The mobile device captures the test result image and transmits it to the remote server for analysis, separating the capture function (local) from the analysis function (remote). This extraction resolves the privacy concern by preventing local storage and analysis of sensitive test data while maintaining testing efficiency through automated remote processing.
Solution Approach 2:
The patent introduces a remote server as an intermediary between the mobile device and the final test result interpretation. The server acts as a trusted third party that receives images, performs analysis, and returns results without exposing sensitive data to local storage or unauthorized access. This intermediary approach maintains productivity while addressing privacy concerns through centralized secure processing.
2Measurement precision
If conventional POCT readers are configured for specific test manufacturers, then analysis accuracy is improved, but adaptability to different test types deteriorates
Solution Approach 1:
The patent implements a universal POCT system where a single remote server can analyze test results from multiple manufacturers and test types. The server uses image recognition algorithms that can identify and interpret different test formats, making the system adaptable to various test manufacturers while maintaining analysis accuracy through standardized image processing and recognition techniques.
Solution Approach 2:
The patent employs parameter changes in the form of adjustable analysis parameters on the remote server. The server can modify analysis parameters such as color thresholds, line detection sensitivity, and result interpretation criteria based on the specific test manufacturer and test type being analyzed. This allows the system to maintain high accuracy across different test formats by dynamically adjusting parameters rather than requiring manufacturer-specific hardware configuration.
3Ease of operation
If human interpretation of test results is used, then flexibility in judgment is improved, but error rate increases
Solution Approach 1:
The patent implements feedback mechanisms where the remote server provides structured analysis results back to the user, and the system can learn from user corrections or confirmations. The automated image analysis provides consistent, objective feedback based on recognized patterns, reducing human error while maintaining flexibility through the ability to review and verify results. The feedback loop ensures reliability through automated consistency while preserving operational flexibility through result verification capabilities.
Solution Approach 2:
The patent replaces the mechanical system of human visual inspection and manual interpretation with an automated image recognition and analysis system. The mobile device captures the test result image, and the remote server uses computer vision algorithms to automatically interpret the results, eliminating transcription errors and subjective judgment variations. This substitution maintains flexibility through programmable analysis rules while significantly improving reliability by removing human error from the interpretation process.
