Converging Nozzle Layout for Uniform Surface Cleaning Spray
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning implements with plural nozzles often produce uneven spray patterns and debris not covered by the fluid are difficult to remove due to insufficient residence time of the cleaning fluid, leading to unsightly trace fluid deposition and potential slipping hazards.
Innovation Solution
A cleaning implement head design with a front edge divided into four quadrants, featuring nozzles oriented towards the longitudinal centerline to create a more contained and uniform spray pattern, minimizing dry areas and ensuring better coverage and solublization of debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If plural nozzles are used to provide broader spray coverage, then the spray pattern coverage is improved, but the spray uniformity deteriorates leading to uneven fluid distribution
Solution Approach 1:
The cleaning implement head is divided into four quadrants with nozzles strategically positioned in outer quadrants, segmenting the spray function to achieve both broad coverage and controlled distribution patterns
Solution Approach 2:
Nozzles are oriented towards the longitudinal centerline with specific angular orientations, creating localized spray directions that converge to produce uniform overall distribution across the target surface
2Area of stationary object
If nozzles are oriented to maximize coverage, then the spray coverage is improved, but trace fluid deposition increases creating slipping hazards
Solution Approach 1:
The nozzle orientation towards the centerline preliminarily directs fluid flow to converge and distribute evenly, preventing the formation of excessive trace fluid deposition before it occurs
Solution Approach 2:
Instead of orienting nozzles outward to maximize edge coverage, the nozzles are oriented inward towards the centerline, inverting the conventional approach to achieve both coverage and prevent harmful trace deposition
3Area of stationary object
If fluid spray diverges from single nozzle, then the spray coverage is improved, but the residence time of fluid on debris deteriorates
Solution Approach 1:
Multiple nozzles are segmented and positioned in outer quadrants, each contributing to a coordinated spray pattern that maintains fluid concentration on the target surface longer than a single diverging nozzle
Solution Approach 2:
The nozzle orientation parameter is changed to point towards the longitudinal centerline, altering the spray trajectory to enhance fluid residence time on the target surface while maintaining broad coverage
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 design achieves a more uniform and extensive spray pattern, increasing the residence time of the cleaning fluid on the target surface, improving debris solublization and reducing unsightly fluid deposition, thus enhancing cleaning efficiency and safety.
Implementation Method 1
Each said nozzle may be oriented towards the longitudinal centerline to spray a fluid towards the centerline

AI summary
A plural nozzle cleaning implement (10). The nozzles (30) 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.
