Plumbing Fixture Fitting Rectangular Spout Removable Flow Restrictor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Designing plumbing fixture fittings that produce a rectangular flow while accommodating removable flow restrictors and stream straighteners for repair or replacement is challenging.
Innovation Solution
A plumbing fixture fitting with a rectangular spout tip and opening, featuring a spout body, a removable flow restrictor housed in a restrictor housing, and a stream straightener, where the restrictor housing is rotatably secured in the spout body's passageway and the stream straightener is removably attached to the outlet, ensuring a generally rectangular laminar flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a rectangular spout tip and opening are designed to produce rectangular flow, then the flow shape is improved, but it becomes difficult to accommodate removable flow restrictors and stream straighteners for repair or replacement
Solution Approach 1:
The spout assembly is segmented into distinct removable components: the flow restrictor, stream straightener, and spout tip can be separated and replaced independently. This allows maintenance of rectangular flow geometry while enabling easy repair and replacement of individual components without replacing the entire spout assembly.
2Ease of repair
If flow restrictors and stream straighteners are made removable for repair or replacement, then ease of repair is improved, but the device complexity increases
Solution Approach 1:
The flow restrictor and stream straightener are nested within the spout tip assembly in a hierarchical manner. The flow restrictor is positioned upstream and the stream straightener downstream, with both components fitting within the rectangular spout tip geometry. This nested arrangement allows easy removal and replacement of individual components while maintaining overall assembly integrity and minimizing complexity.
