Converging Multi-Nozzle Cleaning Head for Uniform Spray Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning implements with plural nozzles often produce uneven spray patterns and debris is not effectively solubilized in regions not covered by the fluid, leading to difficulty in removal and unsightly fluid deposition.
Innovation Solution
A cleaning implement with a head design featuring at least two nozzles oriented towards the longitudinal centerline, providing a contained spray pattern that ensures greater coverage and residence time of the cleaning fluid on the target surface, using a check valve with a diaphragm to prevent backflow and ensure uniform fluid distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single nozzle is used, then the device complexity is reduced, but the spray pattern coverage is insufficient leaving debris in uncovered regions
Solution Approach 1:
The single nozzle is segmented into multiple nozzles (at least two nozzles) arranged in a specific configuration. Each nozzle targets a specific quadrant or region, collectively providing complete coverage of the target surface while maintaining manageable device complexity through modular nozzle design.
Solution Approach 2:
Each nozzle is oriented to spray fluid toward the longitudinal centerline, creating localized spray zones that collectively cover the entire target area. This local orientation strategy ensures that each nozzle contributes to a specific region's coverage while the combined effect achieves uniform overall coverage.
2Area of stationary object
If plural nozzles are used to improve spray pattern coverage, then the coverage area increases, but the spray pattern becomes uneven causing trace fluid deposition
Solution Approach 1:
The nozzles are asymmetrically oriented toward the longitudinal centerline rather than spraying in symmetric fan patterns. This asymmetric orientation toward a central target point creates more uniform convergence of spray patterns, reducing uneven distribution and trace fluid deposition while maintaining comprehensive coverage.
Solution Approach 2:
The nozzle orientation toward the longitudinal centerline creates a self-correcting spray pattern where fluid naturally converges to the centerline region. This geometric feedback mechanism ensures uniform distribution by directing all nozzles toward a common reference point, preventing over-spray in any single region.
3Area of stationary object
If nozzles spray fluid in a diverging fan or cone shape, then the spray disperses widely, but the residence time of fluid on debris is minimal reducing solubilization effectiveness
Solution Approach 1:
The nozzles are pre-oriented to spray toward the longitudinal centerline, creating a converging rather than diverging spray pattern. This preliminary geometric configuration ensures that fluid is deposited in a concentrated area with extended residence time, allowing thorough solubilization of debris before the user moves to the next section.

AI summary
A plural nozzle cleaning implement. The nozzles are oriented inwardly, to provide a converging spray pattern. The converging spray pattern provides more coverage of the target surface, which increases residence time of fluid sprayed onto debris.
