Urinal Flush Assembly Arc Outlet Flow Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flush assemblies for plumbing fixtures do not provide a highly efficient flush water flow profile, leading to inadequate cleaning of the fixtures after multiple uses.
Innovation Solution
A flush assembly comprising a sprayer body with a bottom wall featuring multiple outlets, including a first outlet with an arc shape, and optionally second and third outlets positioned symmetrically, which are configured to provide a continuous and efficient flush water flow profile during a flush cycle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional sprayer body with simple outlet configuration is used, then the device complexity is low, but the flush water flow profile efficiency is insufficient
Solution Approach 1:
The sprayer body is segmented into multiple outlets (first outlet, second outlet, third outlet) with different configurations. Each outlet serves a specific function in creating the overall flush water flow profile, allowing the system to achieve high efficiency through distributed functionality rather than a single complex outlet.
Solution Approach 2:
Different outlets are positioned at specific locations on the sprayer body bottom wall with distinct orientations. The first outlet has a downward orientation while the second and third outlets are positioned at opposing ends, creating localized flow characteristics that collectively produce the desired large area continuous flow profile.
2Productivity
If multiple outlets are added to the sprayer body to improve flow profile, then the flush efficiency is improved, but the manufacturing complexity increases
Solution Approach 1:
Multiple outlets are integrated into a single sprayer body structure, combining their functions into one manufactured component. This merging approach allows the complex multi-outlet configuration to be produced as a single piece through molding or machining, reducing assembly complexity while maintaining the productivity benefits of multiple outlets.
3Reliability
If outlets are positioned to create large area flow profile, then the cleaning effectiveness is improved, but the risk of spillage increases
Solution Approach 1:
The outlet parameters including orientation angles, positioning coordinates, and opening dimensions are precisely controlled during manufacturing. The first outlet is oriented downward while the second and third outlets are positioned at specific opposing ends, creating a flow distribution pattern that achieves broad coverage without excessive spray dispersion that would cause spillage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The flush assembly achieves a large area, continuous flow profile that effectively cleans the plumbing fixture without spillage, ensuring the fixture remains clean after multiple uses, regardless of varying water pressures.
Implementation Method 1
the sprayer body bottom wall comprises a first outlet through which flush water is delivered during a flush cycle
Data Source
AI summary
A flush assembly for a plumbing fixture, the assembly comprising a sprayer body, wherein the sprayer body comprises a bottom wall, a front wall, and a rear wall, the sprayer body is configured to be in fluid communication with a water source, and the sprayer body bottom wall comprises a first outlet through which flush water is delivered during a flush cycle. The first outlet may comprise a slot shape and/or an arc slot shape. The flush assembly provides a large flush profile.
