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 complexity and inefficiency due to the need for rotating fluid delivery components to achieve uniform coverage, which increases cost and reduces reliability.
Innovation Solution
A multiple nozzle differential fluid delivery head with swirl nozzles oriented at varying angles to adjust spray cone angles based on distance, ensuring uniform coverage without rotation, using a static design with a body, outlet ports, and removable nozzle inserts to control spray characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If rotating fluid delivery components are used to achieve uniform coverage, then cleaning coverage is improved, but device complexity and cost increase
Solution Approach 1:
The fluid delivery head is divided into multiple fixed nozzle sections, each oriented at different angles to cover different areas. This segmentation replaces the need for a single rotating nozzle while achieving uniform coverage through multiple stationary spray directions.
Solution Approach 2:
Each nozzle within the fluid delivery head is configured with specific local characteristics (angle, orientation, spray pattern) tailored to its position and the specific area it needs to cover. This allows each nozzle to optimize its spray for its local region, achieving overall uniform coverage without rotation.
2Manufacturing precision
If rotating fluid delivery components are used to achieve uniform coverage, then cleaning coverage is improved, but reliability decreases
Solution Approach 1:
The rotation mechanism is extracted and removed from the system. Instead of a single nozzle that rotates to cover all areas, multiple fixed nozzles are used, each permanently oriented to cover its specific area. This eliminates the moving parts and mechanical complexity associated with rotation, thereby improving reliability.
3Manufacturing precision
If multiple separate spray heads are used to cover different areas, then cleaning coverage is improved, but piping complexity increases
Solution Approach 1:
Multiple nozzle functions are merged into a single integrated fluid delivery head. Instead of having separate spray heads requiring separate piping, all nozzles are combined into one unit with a single fluid inlet, simplifying the piping arrangement while maintaining comprehensive coverage.
Solution Approach 2:
The single fluid delivery head performs multiple functions by incorporating nozzles oriented in different directions. This multi-functional design allows one device to cover multiple areas that would otherwise require separate spray heads, simplifying both the device and its piping.
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 uniform chemical coverage on the inner surfaces of enclosures, reducing complexity and cost while enhancing reliability by using a non-rotating static fluid delivery head with adjustable nozzle inserts for varying spray patterns.
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.
