Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid measurement channel apparatuses suffer from deformation of partition plates due to thermal expansion when the temperature of the measured fluid changes, affecting measurement accuracy.
Innovation Solution
A fluid measurement channel apparatus with a partition plate design where one end is fixed and the other end is slidable, allowing the partition plate to expand and contract freely, maintaining uniformity and preventing deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the partition plate is fixed rigidly at both ends, then the structural stability is improved, but the partition plate deforms due to thermal expansion when fluid temperature changes
Solution Approach 1:
The partition plate is designed with one fixed end and one movable end, allowing it to dynamically adjust its position in response to thermal expansion while maintaining structural stability. The movable end can slide along the channel wall, converting thermal expansion into linear motion rather than deformation.
Solution Approach 2:
The attachment method changes from rigid fixation at both ends to a combination of fixed attachment at one end and sliding attachment at the other end. This parameter change in the boundary conditions allows the partition plate to accommodate thermal expansion without deforming.
2Manufacturing precision
If the partition plate is made slidable at one end, then thermal expansion deformation is prevented, but the attachment structure becomes more complex
Solution Approach 1:
A sliding attachment mechanism serves as an intermediary between the partition plate and the channel wall. This intermediary component allows the partition plate to move freely while maintaining a simple and reliable connection, avoiding complex adjustment mechanisms.
3Measurement precision
If the partition plate deforms due to thermal expansion, then the flow distribution becomes uneven, but completely restraining thermal expansion requires complex compensation mechanisms
Solution Approach 1:
The harmful effect of thermal expansion is extracted and converted into useful linear motion of the movable end. By allowing the partition plate to expand freely in one direction, the design eliminates deformation that would affect flow distribution and measurement accuracy without requiring complex compensation mechanisms.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Maintains flow rate measurement accuracy by preventing partition plate deformation and ensuring consistent flow and ultrasonic wave propagation despite temperature changes.
Implementation Method 1
even when the temperature of the fluid to be measured changes, the deformation of the partition plate by the thermal expansion can be prevented

AI summary
A fluid measurement channel apparatus of the present disclosure includes: a channel main body including a channel through which a fluid to be measured flows and which has a rectangular section; a substantially rectangular partition plate located so as to divide a short side of the channel; and attaching portions by which the partition plate is attached to the channel main body and which are located at upstream and downstream sides. One of the attaching portions is a fixed attaching portion fixed to the channel. The other attaching portion is a movable attaching portion that is slidable relative to the channel main body in a longitudinal direction of the partition plate.
