Measuring Cuvette Detachable Window Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measuring cuvettes face challenges in easily removing contaminants from optical accesses, compromising measurement accuracy due to contamination and difficulty in cleaning, while also requiring reliable sealing to prevent ambient gases from entering the sample space under varying pressure conditions.
Innovation Solution
A measuring cuvette design featuring a fastening element that allows for the secure and nondestructive removal and reattachment of window elements, incorporating a sealing element like a packing ring for gas-tight sealing, and an adjustable mechanism to compensate for length tolerances in surrounding components without altering the measuring section length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If window elements are permanently bonded to the vessel wall, then gas-tight sealing is maintained, but cleaning of optical accesses becomes difficult and time-consuming
Solution Approach 1:
The window element is separated from the vessel wall as a detachable component rather than being permanently bonded. The window element can be removed from the vessel wall for cleaning and then reattached, dividing the system into separable parts that can be independently maintained while preserving the overall gas-tight sealing function through dedicated sealing elements.
2Ease of repair
If window elements are made removable for easy cleaning, then maintenance becomes simpler, but reliable sealing against ambient gases becomes more difficult
Solution Approach 1:
A sealing element acts as an intermediary component between the window element and the vessel wall. This sealing element (such as a packing ring) is specifically designed to create a gas-tight seal at the interface where the window element attaches to the vessel wall, enabling easy removal and reattachment while maintaining reliable sealing against ambient gases throughout the pressure cycles.
3Productivity
If the measuring cuvette design is simplified for easy cleaning, then operational efficiency improves, but compensation for length tolerances becomes more difficult
Solution Approach 1:
The adjusting element is nested within or integrated with the fastening element structure. The fastening element serves as the outer structure that attaches the window element to the vessel wall, while the adjusting element is positioned inside or as part of this fastening structure, allowing for length tolerance compensation without adding a separate external adjustment mechanism, thus maintaining operational efficiency while providing the necessary adjustment capability.
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 easy cleaning of window elements, maintains gas-tight sealing, and compensates for length tolerances, ensuring reliable and accurate gas measurements by preventing contamination and maintaining the longest possible measuring section.
Implementation Method 1
a sealing element, especially a packing ring, which prevents gas leakage between the window element and the vessel wall
Implementation Method 2
at least one window element, through which the electromagnetic radiation can be coupled from the outside into the sample space
Implementation Method 3
the property, especially the intensity and/or wavelength, of the radiation changes because of a partial absorption of the radiation by the process gas
Data Source
AI summary
A measuring cuvette (1), for the spectroscopic analysis of a gas sample in a ray path between a radiation source and a detector, preferably suitable for use in a gas-measuring device (19), has a vessel wall (2) that at least partially encloses a sample space (3) for receiving a process gas. At least one window element (4), through which electromagnetic radiation can be coupled into the sample space (3) from the outside, is indirectly or directly connected with the vessel wall (2). An inlet as well as an outlet (5) are included, through which the process gas can be introduced into the sample space (3) and can be removed from the sample space (3). At least one fastening element (6) makes possible both secure fastening of the window element (4) on the vessel wall (2) and separation of the window element (4) from the vessel wall (2) without destruction.
