Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different test strip readers are used, then device versatility is improved, but measurement precision deteriorates due to variations in imaging characteristics
Solution Approach 1:
The patent transforms color data from different imaging devices into a standardized color space (LAB or LMS) by changing the parameter representation of color values. This allows readings from multiple devices with different imaging characteristics to be normalized and compared consistently, resolving the contradiction between device versatility and measurement precision.
2Adaptability or versatility
If color data from multiple readers is integrated, then adaptability is improved, but reliability deteriorates due to inconsistent color information
Solution Approach 1:
The patent introduces a standardized color space (LAB or LMS) as an intermediary representation layer between different imaging devices and the analysis system. This mediator transforms device-specific color values into a common language, enabling reliable integration of data from multiple readers while maintaining system adaptability.
3Measurement precision
If device-specific color analysis is performed, then measurement precision for individual devices is maintained, but adaptability deteriorates
Solution Approach 1:
The patent changes the parameter representation of color data from device-specific color spaces to a standardized color space (LAB or LMS). This transformation maintains the precision of individual device measurements while enabling cross-platform compatibility and integration across multiple devices.

AI summary
A cross-platform web-based system for water testing capable of measuring, analyzing and maintaining the quality of water using a plurality of different test strip readers each configured to obtain a digital image of a reagent test strip, normalize and analyze color information in the digital image by colorimetric analysis, and to transmit a set of colorimetric values corresponding to said digital image to a cross-platform cloud-based system for analysis. The cloud-based server(s) receive the colorimetric values, calculate analyte parts-per-million (ppm), and return the calculated analyte ppm with consistant results no matter which reader is used.
