Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Point of Care Test (POCT) readers are limited in their ability to interpret results from various drug tests from different manufacturers, leading to inaccuracies due to the 'human factor' and privacy concerns, as they are often specific to certain devices and capture, analyze, and produce results at the testing site, making them prone to manipulation and transcription errors.
Innovation Solution
A system utilizing generic mobile computing devices to capture and process images of drug test results, allowing for the use of multiple test types from various manufacturers, with a remote server analyzing the images to provide objective and secure test results, preserving privacy by avoiding local analysis and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional POCT readers are used to interpret drug test results, then test result analysis can be performed at the testing site, but the system is prone to human error, transcription errors, and lacks objectivity
Solution Approach 1:
The patent replaces the mechanical/visual inspection system with an automated image recognition and analysis system. The mobile device captures images of the lateral flow test substrate, and computer algorithms automatically analyze the test results, eliminating human visual inspection and transcription errors while maintaining objective and consistent result interpretation.
Solution Approach 2:
The patent creates a digital copy of the test result by capturing an image of the lateral flow test substrate using a mobile device camera. This digital copy is then analyzed by computer algorithms, replacing the need for direct visual inspection and manual recording, thereby eliminating transcription errors and improving result consistency.
2Ease of operation
If conventional POCT readers are used, then test results can be produced at the testing site, but privacy concerns arise and results are vulnerable to manipulation
Solution Approach 1:
The patent extracts the critical analysis function from the local testing environment and relocates it to a secure remote server. The mobile device captures the test image and transmits it to the remote server for analysis, separating the sensitive result interpretation process from the physical testing site, thereby protecting against on-site manipulation and privacy breaches.
Solution Approach 2:
The patent introduces a remote server as an intermediary between the testing device and the final result delivery. The server receives encrypted image data, performs secure analysis, and returns results through controlled channels, acting as a trusted mediator that protects against manipulation at the testing site while maintaining on-site testing convenience.
3Adaptability or versatility
If multiple specific POCT readers are purchased for different test types, then comprehensive testing capability is achieved, but device complexity and cost increase
Solution Approach 1:
The patent creates a universal testing system where a single mobile device with image capture capabilities can perform multiple test types. The system uses a standardized image capture and transmission protocol that works with various lateral flow test substrates, eliminating the need for multiple specialized POCT readers while maintaining comprehensive testing capability across different drug types and manufacturers.
Solution Approach 2:
The patent replaces the mechanical complexity of multiple specialized POCT readers with a simplified mobile device-based image capture system. By using software algorithms instead of hardware-specific analysis mechanisms, the system achieves multi-test-type capability through a single universal device, dramatically reducing device complexity and cost.

Function Achieved in This Case
Enables accurate, objective, and secure analysis of drug test results across different test types without the need for multiple POCT devices, reducing costs and enhancing privacy by processing results remotely, thus mitigating the risk of unauthorized access or manipulation.
Implementation Method 1
Lateral flow test substrates generally include one or more testing areas (e.g., lines or zones) which are treated with one or more corresponding chemical reagents. As fluid test samples traverse testing areas on lateral flow test substrates...
Implementation Method 2
As fluid test samples traverse testing areas on lateral flow test substrates, chemicals (e.g., drugs, proteins, etc.) in the test samples may react with the chemical reagent(s) in the testing areas. As part of the reaction(s) one or more colors of the testing areas may change or appear based on chemicals present in a particular test sample...
