Measuring Apparatus Bubble Elimination via Inversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The presence of bubbles in liquid measuring samples can inhibit accurate measurement of physical properties, as they can enter during sample preparation or supply, affecting measurement techniques such as electrical, optical, and chemical analyses.
Innovation Solution
A measuring apparatus is designed with a measuring unit installed on the supply route upstream of the preparing unit, ensuring the measurement area remains filled with liquid, preventing bubble formation by withdrawing the measuring sample into the supply route, where it replaces the existing liquid, maintaining a continuous liquid state and minimizing bubble interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the measuring unit is installed in the preparing unit to measure the liquid measuring sample, then the measurement can be performed on the prepared sample, but bubbles may enter the measuring area during preparation and supply, causing measurement errors
Solution Approach 1:
Instead of placing the measuring unit in the preparing unit where bubbles may form and enter, the patent inverts the approach by installing the measuring unit on the supply route upstream of the preparing unit. This allows measurement to be performed on the liquid sample before it enters the preparing unit, ensuring the measuring area remains free of bubbles while still achieving the measurement objective.
Solution Approach 2:
The patent applies preliminary action by performing the measurement on the liquid sample before it undergoes preparation processes that may introduce bubbles. The measuring unit is positioned to measure the physical property of the liquid sample in advance, before the sample is supplied to the preparing unit, thus preventing bubble interference from affecting the measurement.
2Reliability
If the measuring unit is installed on the supply route upstream of the preparing unit, then the measuring area remains filled with liquid preventing bubble formation, but the liquid sample must be withdrawn into the supply route
Solution Approach 1:
The supply route serves multiple functions: it supplies liquid material to the preparing unit for sample preparation and simultaneously serves as the measuring area for the measuring unit. By positioning the measuring unit on the supply route, the system utilizes the existing liquid flow path for both transportation and measurement purposes, avoiding the need for a separate measuring chamber and reducing overall system complexity.

AI summary
A measuring apparatus for measuring a predetermined physical property of a liquid measuring sample comprises a preparing unit in which a plurality of materials including at least a liquid material are mixed; a supply route which supplies the liquid material to the preparing unit; a withdrawing unit which withdraws the measuring sample from the preparing unit into the supply route, the measuring sample being prepared to contain the liquid material supplied to the preparing unit via the supply route; and a measuring unit which measures the predetermined physical property of the measuring sample withdrawn into the supply route by the withdrawing unit.
