Solution Overview

Problem

Conventional aqueous washers are inefficient in using a fraction of the aqueous solution and energy, as they often require repeated application and result in cross-contamination and excessive solution usage.

Innovation Solution

The aqueous washer design features rotatable arms with angled nozzles that cover the part from multiple angles, reducing the need for top wall nozzles and optimizing solution distribution, allowing for a more comprehensive wash with less solution and energy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If conventional fixed risers with nozzles are used to spray solution onto the part, then the part can be treated as it moves past the riser, but excessive amounts of aqueous solution are consumed and energy efficiency is poor

Engineering Contradiction:
Improveaqueous solution consumptionVSAvoidwashing efficiency
Core Design Contradiction:
Loss of substanceVSProductivity

Solution Approach 1:

The patent converts the static fixed riser system into a dynamic rotating arm system. The arms rotate to dynamically position nozzles around the part, allowing comprehensive coverage with fewer nozzles and less solution. The rotation enables each nozzle to serve multiple zones that would otherwise require separate fixed nozzles.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent introduces rotational movement as a new dimension to the spraying system. Instead of only horizontal movement of the part past fixed nozzles, the system adds vertical and radial coverage through arm rotation, creating three-dimensional solution distribution that reduces overall consumption.

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

2Reliability

If conventional fixed risers are used to apply solution repeatedly, then the part receives treatment, but cross-contamination occurs and solution usage is excessive

Engineering Contradiction:
Improvewashing qualityVSAvoidaqueous solution consumption
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The rotating arms provide dynamic positioning that allows controlled, sequential exposure of different part surfaces to the solution. This dynamic approach prevents cross-contamination by systematically moving through washing zones rather than repeatedly exposing all surfaces to solution at once.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The angled nozzles on rotating arms provide localized, targeted solution application to specific zones of the part. Each nozzle is positioned to treat a particular area, ensuring thorough local cleaning without unnecessary exposure of other areas, thereby reducing overall solution consumption while maintaining washing quality.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If fixed risers with nozzles are used to spray solution, then the part can be washed, but a large amount of energy is consumed

Engineering Contradiction:
Improvewashing effectivenessVSAvoidenergy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The rotating arm system consolidates multiple fixed nozzle positions into fewer moving components. This reduces the total number of nozzles required and optimizes solution delivery, thereby reducing the energy needed to pump and distribute the aqueous solution throughout the washing chamber.

Inventive Principle:
Principle #15Dynamics

4Manufacturing precision

If conventional washers use repeated solution application, then the part receives thorough treatment, but evaporation losses increase

Engineering Contradiction:
Improvewash coverageVSAvoidsolution evaporation
Core Design Contradiction:
Manufacturing precisionVSLoss of substance

Solution Approach 1:

The rotating arms deliver solution more efficiently and uniformly across the part surface in a controlled sequence. This dynamic distribution reduces the total volume of solution required and minimizes exposure time, thereby reducing evaporation losses while maintaining comprehensive wash coverage.

Inventive Principle:
Principle #15Dynamics
