Self-Oscillating Nozzle Assembly for Low-Setup Tank Cleaning

Solution Overview

Problem

Existing fluid holding tanks, such as those on boats or drilling rigs, require complex and time-consuming manual cleaning processes due to the enclosed and poorly ventilated nature, posing safety risks and increasing the potential for setup-related issues.

Innovation Solution

A self-oscillating nozzle assembly with a fluid manifold and actuatable valves, controlled by a computer, that rotates through selectable oscillation patterns to automate the cleaning process without the need for external control lines, allowing for easy installation and remote operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual cleaning is performed in enclosed tanks, then cleaning can be done, but safety risks increase and setup time is significant

Engineering Contradiction:

ImprovesafetyVSAvoidsetup time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The nozzle assembly performs self-oscillation and self-direction control using the fluid flow itself, without requiring external control lines or manual operation inside the tank. The system serves itself by using the cleaning fluid to power the oscillation mechanism, eliminating the need for complex external control systems and manual setup.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces complex mechanical control systems with a fluid-driven self-oscillating mechanism. Instead of using external hoses, wires, or mechanical linkages to control nozzle movement, the system uses the fluid flow pattern and pressure differential to automatically oscillate the nozzle, substituting a complex mechanical control system with a simpler fluid-dynamic system.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If automated cleaning devices are used, then safety is improved, but device complexity and setup requirements increase

Engineering Contradiction:

ImprovesafetyVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the control function from the nozzle assembly itself, eliminating the need for external control lines, valves, and actuators that would normally be required for automated nozzle control. The oscillation and direction control are taken out of the external system and integrated into the fluid flow pattern within the nozzle.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The nozzle assembly performs multiple functions simultaneously: it delivers cleaning fluid, controls its own oscillation, and adjusts its own direction using the same fluid flow. This multi-functionality eliminates the need for separate control systems, reducing overall device complexity while maintaining automated operation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Extent of automation

If complex setup procedures are required, then automated cleaning can be achieved, but potential for problems and risk increase

AI summary

Systems and methods deliver fluid using a nozzle assembly that rotates through a selectable oscillation pattern for cleaning tanks. The nozzle assembly rotates through the oscillation pattern automatically without requiring external manipulation of fluid flow through control lines. Installers use a quick mount and clamp assembly to secure the nozzle assembly inside of the tank. A smart manifold provides remote control of several of the nozzle assembly once installed in the tank.
