Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single cuvette uses intersecting analysis sections to analyze fluids of different concentrations, then the cuvette can handle multiple analysis types, but the workflow is interrupted by rotation and contamination risks increase
Solution Approach 1:
The cuvette is divided into separate, non-intersecting analysis sections (first analysis section and second analysis section) that are spatially separated. Each section has its own dedicated analysis path, allowing simultaneous analysis of different fluid concentrations without requiring rotation or causing cross-contamination between sections.
Solution Approach 2:
The analysis sections are arranged in different spatial dimensions within the cuvette structure. The first analysis section and second analysis section are positioned such that their analysis paths do not intersect, utilizing three-dimensional space to accommodate multiple analysis functions simultaneously without interference.
2Adaptability or versatility
If cuvettes are rotated to switch between analysis sections, then different concentration ranges can be analyzed, but time is lost and workflow efficiency decreases
Solution Approach 1:
The cuvette contains multiple distinct analysis sections (first and second analysis sections) with different path lengths, allowing the system to select the appropriate section for the desired concentration range without physical movement or rotation of the cuvette, thereby maintaining continuous workflow.
Solution Approach 2:
The analysis process continues uninterrupted because the cuvette remains in a fixed position while the system selectively uses different analysis sections. This eliminates the need for rotation or repositioning, ensuring continuous measurement without workflow interruptions.
3Adaptability or versatility
If intersecting analysis paths are used in a cuvette, then multiple analysis sections can be integrated, but measurement distortion occurs in the intersection area
Solution Approach 1:
The analysis sections are segmented into separate, non-overlapping regions within the cuvette. The first analysis section and second analysis section have distinct spatial boundaries and do not intersect, eliminating the measurement distortion that would occur in intersection areas while maintaining the ability to analyze different fluid concentrations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient, safe, and cost-effective analysis of fluids with reduced error rates by allowing simultaneous analysis in a single cuvette, enhancing workflow efficiency and safety.
Implementation Method 1
The movement of a pump element creates a vacuum in the pipette tip, causing the liquid to rise into the tip.
Implementation Method 2
creates a vacuum in the pipette tip, causing the liquid to rise into the tip
Implementation Method 3
The air column moved by the pump element creates a fluid flow, which in turn moves the liquid into and out of the pipette tip.
Implementation Method 4
Absorption photometers have a shaft with a corresponding cross-section into which the cuvettes can be inserted. The beam path of the illumination device runs transversely through this cuvette shaft. The degree of attenuation of the beam path when passing through the sample, for example containing dyes (the attenuation due to the glass of the cuvette itself is taken into account as a constant), denotes the light absorption of the sample
