Arched Warewashing Arm With Overlapping Spray Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional warewashing systems, the linear arms with nozzles arranged perpendicular to the ware result in inefficient spray patterns, leading to wasted water, detergents, and sanitizers, as the sprays often miss the intended target, reducing effectiveness and increasing consumption.
Innovation Solution
An arched tubular arm with nozzles angled to overlap their spray patterns, maximizing coverage and minimizing waste by directing the sprays inwardly towards the center of the chamber, ensuring that water, detergents, and sanitizers effectively reach the ware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If linear arms with perpendicular nozzles are used, then the spray pattern covers a wide area, but the spray misses the intended target and creates waste areas
Solution Approach 1:
The arm is designed with a curved or arched configuration instead of a straight linear shape. This curvature allows the nozzles to be positioned and angled such that their spray patterns converge toward the center of the chamber, ensuring better target coverage while reducing waste areas where spray misses the ware.
2Ease of manufacture
If nozzles are arranged perpendicular to the ware, then the spray dispersion pattern is simple and easy to manufacture, but the spray effectiveness is reduced due to missed targets
Solution Approach 1:
The nozzles are angled at different orientations rather than all being perpendicular. Specifically, nozzles are configured with angles such that sprays from adjacent nozzles overlap, creating enhanced coverage in critical areas and ensuring that the spray effectively reaches the ware throughout the chamber.
3Device complexity
If spray nozzles are distributed along a linear arm, then the device complexity is low, but the spray patterns create uncovered areas and waste
Solution Approach 1:
The arm is designed with a curved or arched configuration instead of a straight linear shape. This curvature allows the nozzles to be positioned and angled such that their spray patterns converge toward the center of the chamber, ensuring better target coverage and eliminating uncovered areas that would compromise sanitization effectiveness.
Solution Approach 2:
The spray patterns are configured to overlap in a three-dimensional space rather than simply dispersing in a single plane. By angling the nozzles and curving the arm, the spray coverage extends through multiple dimensions, ensuring complete coverage of the ware and eliminating cross-sectional areas where spray would otherwise miss the target.
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 arched arm design significantly reduces waste areas, achieving 100% detergent removal and up to 500% increase in effective spray coverage, improving cleanliness and sanitization while reducing water and chemical consumption, and enabling more efficient use of resources.

AI summary
A rinse arm or wash arm includes a tubular body connected to a fluid source. The tubular body has at least a first aperture and a second aperture therethrough. The first aperture forms a first spray and the second aperture forms a second spray when the fluid flows through the tubular body from the fluid source. The first aperture has a first aperture axis therethrough and the second aperture has a second aperture axis therethrough. The first aperture axis forms a first angle with a first vertical axis and the second aperture axis forms a second angle with a second vertical axis. The first angle is greater than 0 degrees, so that the first aperture directs the first spray towards the second spray forming an overlapping spray of the first spray and the second spray.
