Solution Overview

Problem

Conventional precision cleaning systems struggle to evenly and quickly clean large masses of small parts in bulk, often resulting in uneven cleaning, inadequate rinse flow, and the retention of particulate matter.

Innovation Solution

A directed flow pressure washer system that uses a plurality of inlets connected to an elongated pipe tubing, allowing for the simultaneous or intermittent introduction of gas, detergent, and solvent, which are filtered to a predetermined micron level. This system creates a directed variable pressure and flow rate to ensure thorough cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If parts are placed in a basket for bulk cleaning, then productivity is improved by cleaning large masses of parts, but manufacturing precision deteriorates because the outermost parts receive the best cleaning while inner parts are inadequately cleaned

Engineering Contradiction:
Improvebulk cleaning capacityVSAvoidcleaning consistency
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The system segments the cleaning process into multiple injection points along the tubing length, with nozzles positioned at different locations to direct cleaning fluid at parts from multiple angles, ensuring uniform cleaning throughout the bulk mass

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system uses pressurized fluid injection through multiple nozzles along the tubing to create directed flow patterns that penetrate the bulk mass of parts, replacing the inadequate single-point spray approach with a distributed hydraulic cleaning field

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Stress or pressure

If pressure washing is applied to bulk parts, then cleaning intensity is improved near the nozzle, but manufacturing precision deteriorates because pressure is quickly dissipated by distance and deflection

Engineering Contradiction:
Improvecleaning pressure intensityVSAvoidcleaning uniformity
Core Design Contradiction:
Stress or pressureVSManufacturing precision

Solution Approach 1:

The cleaning system is divided into multiple injection zones along the tubing, each with its own nozzle providing localized high-pressure cleaning. This segmentation maintains pressure intensity across the entire bulk mass by distributing multiple pressure sources rather than relying on a single nozzle

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the tubing receive cleaning fluid at optimized pressure and angle specific to their location, with nozzles positioned to target specific areas of the bulk part mass, ensuring each local region receives appropriate cleaning intensity

Inventive Principle:
Principle #3Local quality

3Ease of operation

If conventional cleaning systems use trays, racks and baskets to hold parts, then ease of operation is improved by simple part containment, but manufacturing precision deteriorates because parts are not evenly exposed to cleaning flow

Engineering Contradiction:
Improvepart containment simplicityVSAvoidcleaning exposure consistency
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The system replaces static containment structures with a dynamic pressurized fluid delivery system that actively directs cleaning flow throughout the part mass, using hydraulic pressure to ensure uniform exposure without requiring complex mechanical containment arrangements

Inventive Principle:
Principle #29Pneumatics and hydraulics

Solution Approach 2:

The system transitions from two-dimensional surface cleaning (trays and racks) to three-dimensional volumetric cleaning by injecting pressurized fluid throughout the bulk mass, enabling cleaning penetration in all spatial dimensions simultaneously

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Manufacturing precision

If smaller batches are used for cleaning to improve consistency, then manufacturing precision is improved, but productivity deteriorates due to increased cleaning time and cost

Engineering Contradiction:
Improvecleaning consistencyVSAvoidcleaning throughput
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The system maintains high cleaning consistency by segmenting the fluid delivery into multiple controlled injection zones, allowing each zone to be optimized for uniform distribution while processing large bulk quantities simultaneously, thus achieving both precision and throughput

Inventive Principle:
Principle #1Segmentation

AI summary

A directed flow pressure washer system for precision cleaning of one or more parts includes a gas source containing a gas, a solvent source containing a solvent, and a plurality of inlets connected to an elongated pipe tubing. The gas source is connected to a first inlet. The first inlet is configured to receive the gas therethrough, the solvent source is connected to a second inlet, and the second inlet is configured to receive the solvent therethrough. The system includes a component retainer removably attached to the elongated pipe tubing. The parts are located in the elongated pipe tubing at the distal end such that the parts are exposed to a directed variable pressure and flow rate of the gas and/or the solvent. The component retainer is configured with one or more openings at an outlet thereof to allow particles therethrough while retaining the parts during cleaning.
