Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing cleaning detection methods are used, then detection accuracy is improved, but detection time increases and requires specialized equipment and training
Solution Approach 1:
The patent employs a colorimetric detection method where the composition changes color in the presence of protein soils or biofilms. The copper sulfate reacts with proteins to produce a visible color change (typically blue-green), enabling rapid visual detection without specialized equipment. This directly addresses the contradiction by providing both accurate detection and rapid results within seconds.
Solution Approach 2:
The invention uses a simple, inexpensive chemical composition that can be applied directly to surfaces for immediate detection. The composition is designed for single-use application where it is sprayed or applied to the surface, allowed to react briefly, and then discarded or rinsed off. This eliminates the need for expensive, reusable specialized equipment while maintaining detection accuracy.
2Reliability
If existing cleaning detection methods are used, then detection reliability is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The detection composition is designed to be self-indicating through color change, eliminating the need for complex measurement instruments or trained operators. The chemical reaction automatically provides a visual signal when protein soils are detected, making the system reliable yet simple to operate by any personnel without specialized training.
Solution Approach 2:
The patent replaces complex mechanical or electronic detection systems with a simple chemical reaction system. Instead of using sophisticated instruments that require calibration and maintenance, the invention uses a chemical composition that automatically reacts with protein soils to produce a visible color change, simplifying the entire detection apparatus to just the chemical solution and application method.
3Productivity
If rapid detection is implemented, then productivity is improved, but measurement precision may deteriorate
Solution Approach 1:
The composition is formulated with specific pH levels and chemical concentrations optimized for rapid reaction with protein soils. The copper sulfate and other reagents are selected and dosed to achieve fast color development (within seconds) while maintaining sufficient sensitivity to detect even small amounts of protein contamination, thus achieving both speed and accuracy.
