Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of housings for flow measuring devices is complex and can compromise the stability of the measuring tube, particularly in magneto-inductive devices where central support reduces stability and involves multiple components.
Innovation Solution
A housing design using two wall elements made from sheet material, with folded sections and minimal moment of inertia, supporting the measuring tube at both ends and incorporating threaded sleeves for secure attachment, a plug-in connector for electronics, and a casting opening for thermal decoupling, which are laser-welded for stability and assembly efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a housing is produced from an outer tube and two side panes with central support of the measuring tube, then the housing can be assembled with multiple components, but the manufacturing complexity increases and the stability of the measuring tube decreases
Solution Approach 1:
The patent combines multiple housing components into a single piece housing. The measuring tube support is integrated directly into the housing body as a continuous structure, eliminating the need for separate side panes and outer tubes. This merging of components reduces assembly complexity while maintaining structural integrity and measuring tube stability.
2Ease of operation
If the measuring tube is centrally supported by side panes, then the housing can accommodate electronic components, but the stability of the measuring tube with respect to the housing is reduced
Solution Approach 1:
The patent implements local reinforcement at the measuring tube support locations within the housing body. The housing features localized support structures (recesses or ledges) positioned at specific points along the measuring tube length, providing enhanced stability where needed while maintaining the overall housing structure for electronic component accommodation. This localized support approach prevents measuring tube displacement without requiring complex central support mechanisms.
