Solution Overview
Problem
Existing ultrasonic fluid-measuring apparatuses face disturbances in ultrasonic waves due to fluid flow, particularly caused by steps and gaps in the channel design, which can lead to inaccurate flow rate measurements.
Innovation Solution
The ultrasonic fluid-measuring structure features a channel member with a continuous rectangular opening and an ultrasonic measuring section, where the first and second ultrasonic wave input/output sections are adjacent and covered by an ultrasonic wave transmission membrane, eliminating steps and gaps that could cause disturbances, and integrating the channel's components to reduce complexity and prevent fluid-induced disturbances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a pillar portion is provided between the first and second ultrasonic wave output sections in the first side wall part, then the ultrasonic wave output sections are supported structurally, but disturbance occurs in the fluid flow and ultrasonic waves due to steps and gaps formed by the pillar portion
Solution Approach 1:
The invention removes the pillar portion that protrudes into the channel from the first side wall part. By extracting this harmful structural element, the steps and gaps that caused fluid disturbance and ultrasonic wave interference are eliminated, thereby improving measurement precision without compromising overall structural integrity
Solution Approach 2:
The invention converts the harmful effect of the pillar portion by redesigning the mounting structure. The ultrasonic wave output sections are now mounted in a way that does not require protruding pillars, transforming the harmful structural support method into a beneficial streamlined design that maintains strength while eliminating disturbance
2Device complexity
If the first and second ultrasonic wave output sections are arranged adjacent to each other in the first side wall part, then the device complexity is reduced, but steps and gaps are formed that cause disturbance in fluid flow and ultrasonic waves
Solution Approach 1:
The invention extracts the harmful pillar portion that was necessary to support adjacent ultrasonic wave output sections. By removing this protruding structure and redesigning the mounting approach, the device maintains its simplified component arrangement while eliminating the steps and gaps that caused measurement errors
Solution Approach 2:
The invention applies local quality by modifying only the specific mounting area of the ultrasonic wave output sections. The first side wall part is redesigned locally to accommodate adjacent output sections without protruding pillars, maintaining simplicity elsewhere in the device while improving measurement precision at the critical ultrasonic transmission interface

Implementation Method 1
a first transmitter/receiver that transmits ultrasonic waves to the reflecting surface through the first ultrasonic wave input/output section and receives the ultrasonic waves reflected by the reflecting surface, and a second transmitter/receiver that transmits the ultrasonic waves to the reflecting surface through the second ultrasonic wave input/output section and receives the ultrasonic waves reflected by the reflecting surface
Implementation Method 2
