Multiple Nozzle Fluid Delivery Head for Uniform Cleaning Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated cleaning systems for toilet bowls, shower enclosures, and bathtub enclosures face challenges in achieving uniform coverage of cleaning agents due to varying distances and orientations of surface areas, often requiring complex rotating components that increase cost and reduce reliability.
Innovation Solution
A multiple nozzle differential fluid delivery head with swirl nozzles oriented at different angles to adjust spray cone angles based on distance, ensuring uniform coverage without rotating components, using a body with angled outlet ports and removable nozzle inserts to control spray characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rotating fluid delivery components are used to treat surfaces at different distances and orientations, then appropriate treatment for all parts of the surface is achieved, but the system becomes cumbersome and complex
Solution Approach 1:
The fluid delivery head is divided into multiple independent nozzles, each oriented at different angles to target specific areas of the enclosure. This segmentation allows the static head to cover various surfaces without requiring rotation or complex mechanisms.
Solution Approach 2:
Each nozzle within the fluid delivery head is configured with specific angular orientations and spray characteristics tailored to its designated target area. This local optimization enables the static system to achieve uniform coverage across different distances and orientations.
2Adaptability or versatility
If multiple separate spray heads are used to clean different areas, then complete coverage is achieved, but complicated fluid piping arrangements are required
Solution Approach 1:
Multiple nozzles with different orientations are integrated into a single fluid delivery head, sharing a common fluid supply. This merging eliminates the need for separate piping arrangements for each spray head while maintaining comprehensive coverage capability.
Solution Approach 2:
The single fluid delivery head performs multiple functions by directing different nozzles at various angles to cover different areas of the enclosure, replacing the need for multiple separate spray heads and their associated piping systems.
3Device complexity
If a single spray head is used, then the system is simple, but coverage is limited to one location or area
Solution Approach 1:
The fluid delivery head contains multiple nozzles segmented into different angular orientations, allowing a single compact device to cover multiple areas simultaneously while maintaining system simplicity.
Solution Approach 2:
The nozzles are arranged in three-dimensional space with different angular orientations, enabling the single fluid delivery head to cover a volumetric region rather than a single planar area, thus expanding coverage without increasing complexity.
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 solution provides a static, cost-effective, and reliable method for achieving uniform coverage of cleaning agents on the inner surfaces of enclosures, enhancing the efficiency and effectiveness of automated cleaning systems.
Implementation Method 1
Each of these nozzles is based on a swirl nozzle configuration. A swirl nozzle provides a conical spray and the characteristics of the spray such as velocity, drop size, cone angle, discharge rate etc., will depend upon the internal geometric details of the nozzle.

AI summary
A multiple nozzle differential fluid delivery head is disclosed. The fluid delivery head includes a body that defines a fluid chamber having a longitudinal axis. The body includes an inlet for connection to a fluid source, and the inlet is in fluid communication with the fluid chamber. The fluid delivery head includes a plurality of outlet ports connected to and extending away from the body. Each outlet port has an interior space in fluid communication with the fluid chamber. The fluid delivery head includes a nozzle insert removably secured in an outer end of each outlet port. At least one nozzle insert has a fluid delivery aperture in fluid communication with the interior space of its associated outlet port for delivering fluid out of the interior space of its associated outlet port. One or more of the outlet ports is angled away from a plane normal to the axis of the fluid delivery head.
