Integrated Flowmeter Housing for Hygienic Washability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fluid measurement devices face increased manufacturing costs and reduced washability due to complex coupling and welding processes, leading to irregularities that complicate hygiene maintenance, especially in applications involving food and beverages.
Innovation Solution
The device integrates a housing with a supporting portion and an accommodation portion formed by a metal material, eliminating the need for separate housings and welded connections, thereby reducing manufacturing costs and preventing irregularities, enhancing washability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If separate housings are coupled via coupling portion or welding, then structural support is achieved, but manufacturing cost increases
Solution Approach 1:
The patent combines the first housing and second housing into a single integrated housing structure. The support portion that previously required separate coupling components is now formed as an integral part of the housing, eliminating the need for separate coupling portions and reducing assembly steps while maintaining structural support functionality
Solution Approach 2:
The integrated housing serves multiple functions simultaneously: it provides structural support, houses the processing device, and eliminates the need for separate coupling components. The support portion is designed to both support the measurement tube and serve as the structural connection between what would have been separate housing sections
2Stability of the object's composition
If coupling portion or welded portion is used to connect housings, then structural assembly is achieved, but irregularities such as gaps occur between housings
Solution Approach 1:
By merging the first and second housings into a single integrated housing, the patent eliminates the interface between separate components that would create gaps and irregularities. The support portion is formed as a continuous integral structure, ensuring a smooth surface without joints or welds
3Strength
If welded portion with welded trace is formed, then housing connection is achieved, but washability of outer circumferential portion decreases
Solution Approach 1:
The integrated housing design eliminates welded portions and their associated traces by forming the support portion as a seamless integral structure. This smooth, continuous surface without weld joints enables complete washing and removal of fluid residues, meeting food hygiene requirements

AI summary
A fluid measurement device includes a measurement tube through which a fluid flows, a measurement element that is provided at the measurement tube and that measures the fluid, a processing device that processes a signal that has been measured by the measurement element, and a housing that includes a supporting portion that is formed in a cylindrical shape and that supports the measurement tube that is provided to pass through the supporting portion, and an accommodation portion that is formed in a cylindrical shape and that accommodates the processing device, and in which the supporting portion and the accommodation portion are integrally formed by a metal material.
