Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple vessels are used for analysis, then the analysis process is more robust, but handling complexity and time consumption increase
Solution Approach 1:
The patent merges multiple separate vessels into a single integrated cuvette with multiple chambers. Each chamber can hold different liquids or samples, allowing multiple analysis steps to occur in one vessel. This eliminates the need to transfer samples between multiple vessels, reducing handling complexity while maintaining analysis robustness through the integrated multi-chamber design.
2Adaptability or versatility
If multiple vessels are used for analysis, then comprehensive analysis is possible, but material usage and time consumption increase
Solution Approach 1:
The cuvette integrates multiple chambers that can simultaneously hold different samples or reagents, allowing comprehensive analysis to be performed in a single vessel. This eliminates sequential transfer operations between multiple vessels, significantly reducing time consumption while maintaining the ability to perform comprehensive multi-parameter analysis.
Solution Approach 2:
The single cuvette is designed to perform multiple functions - it can hold different types of samples, reagents, and control solutions in its various chambers. This multi-functional design allows comprehensive analysis of multiple parameters or samples without requiring separate specialized vessels for each type of analysis, reducing both time and material usage.
3Ease of manufacture
If conventional cuvette geometry is used, then manufacturing is simple, but optical measurement sensitivity is reduced
Solution Approach 1:
The cuvette incorporates curved surfaces and optimized geometric shapes in its chamber design. These curved geometries are specifically designed to enhance light refraction and focusing properties, improving optical measurement sensitivity. The curved surfaces help concentrate light paths and reduce stray light, thereby enhancing detection sensitivity while remaining manufacturable using standard molding techniques.
