Measurement Cuvette Orientation Structure for Damage-Free Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measuring cuvettes and radiation components suffer from unreliable and potentially damaging orientation and alignment issues due to low component stiffness, leading to incorrect coupling and deformation of the U-shaped frame, which compromises the alignment structure's effectiveness.
Innovation Solution
The cuvette and radiation component are designed with orientation and aligning structures that vary in distance and dimension orthogonally to their respective axes, ensuring correct coupling by preventing collisions and distributing mechanical stress, and incorporating latching elements for secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the U-shaped frame has low component stiffness, then the measuring cuvette is easier to manufacture and assemble, but the alignment structure becomes ineffective and deformation occurs during coupling
Solution Approach 1:
The patent changes the geometric parameters of the orientation structure, specifically varying the distance to the longitudinal axis and/or the dimension orthogonally to the longitudinal axis along the longitudinal axis. This parameter variation creates an asymmetric shape that provides mechanical stability and prevents deformation during coupling, while still allowing for easy manufacture through standard molding processes.
Solution Approach 2:
The orientation structure is designed with asymmetric geometry where the distance to the longitudinal axis and/or the orthogonal dimension varies along the longitudinal axis. This asymmetry creates a unique fit between the measuring cuvette and radiation component, preventing incorrect orientation while maintaining structural integrity and resistance to deformation during the coupling process.
2Ease of manufacture
If the orientation structure has uniform distance and dimension, then the manufacturing is simpler, but incorrect orientation can occur leading to collisions and damage
Solution Approach 1:
The patent implements asymmetry by designing the orientation structure with varying distance to the longitudinal axis and/or varying orthogonal dimension along the longitudinal axis. This asymmetric configuration creates a unique geometric key that ensures the measuring cuvette can only be coupled in the correct orientation, preventing mismatches and collisions while remaining manufacturable through standard processes.
Solution Approach 2:
The orientation structure exhibits local quality variations along its length, with different sections having different distances to the longitudinal axis and/or different orthogonal dimensions. This local variation creates specific engagement points that guide correct orientation during coupling, ensuring reliability at critical locations while maintaining overall manufacturing simplicity.
3Productivity
If the coupling force is applied at a single point, then the coupling process is faster, but the alignment structure deforms and loses effectiveness
Solution Approach 1:
The orientation structure is segmented into multiple sections along the longitudinal axis, each with varying distance to the longitudinal axis and/or varying orthogonal dimension. This segmentation distributes the coupling force across multiple engagement points rather than a single point, preventing localized deformation while maintaining fast coupling through the guided asymmetric geometry.
Solution Approach 2:
The patent utilizes variation in two dimensions (distance to longitudinal axis and orthogonal dimension) along the longitudinal axis to create the orientation structure. This multi-dimensional approach distributes mechanical stress across a larger volume and multiple contact points, enhancing stability and preventing deformation while maintaining efficient coupling.

AI summary
A measurement cuvette for detecting at least one fluid constituent of a fluid flowing through the measurement cuvette by means of electromagnetic radiation, includes: a channel, which extends through the measurement cuvette along a channel path extending centrally through the channel; a coupling and detection portion, which extends, between its first longitudinal end and its second longitudinal end, along a linear longitudinal axis, detachably mechanically coupled to a radiation component; a physical orientation structure, which allows detachable mechanical coupling of the measurement cuvette to the radiation component in a predefined desired relative orientation and prevents the detachable mechanical coupling in an undesired relative orientation. The physical orientation structure is arranged and formed between the first and the second longitudinal ends of the coupling and detection portion.
