Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual cleaning with cleaning fluid is used, then cleaning can be performed, but cleaning effectiveness is insufficient and requires manual effort

Engineering Contradiction:

Improvecleaning effectivenessVSAvoidmanual effort required

Core Design Contradiction:

Ease of operationVSExtent of automation

Solution Approach 1:

The cleaning device enables self-service cleaning by automatically guiding the nozzle through the brush bristles using a movement device, eliminating the need for manual cleaning operations while achieving thorough cleaning through automated relative motion between nozzle and bristles

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system employs dynamic relative motion between the nozzle and brush bristles through the movement device, which moves the nozzle relative to the brush through the cleaning area, creating vigorous movement of cleaning fluid through the bristles for enhanced cleaning effectiveness

Inventive Principle:

Principle #15Dynamics

2Manufacturing precision

If cleaning fluid is applied to brush bristles, then residues can be removed, but deep penetration into bristles is insufficient

Engineering Contradiction:

Improvecleaning thoroughnessVSAvoidpenetration depth into bristles

Core Design Contradiction:

Manufacturing precisionVSLength of stationary object

Solution Approach 1:

The movement device creates dynamic relative motion that forces cleaning fluid deep into the bristles, with the nozzle moving through the cleaning area to vigorously push cleaning fluid through the bristle structure, achieving deep penetration and thorough residue removal

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system uses hydraulic pressure through the cleaning fluid supply to deliver cleaning fluid under pressure to the nozzle, which then forces the fluid deep into the bristles through the relative motion created by the movement device, ensuring deep penetration

Inventive Principle:

Principle #29Pneumatics and hydraulics

3Productivity

If multiple brushes are cleaned simultaneously, then productivity increases, but device complexity increases

Engineering Contradiction:

Improvenumber of brushes cleaned simultaneouslyVSAvoidstructure complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The cleaning device achieves multi-functionality by incorporating multiple brush holders that can simultaneously hold and clean multiple brushes, with the single nozzle system serving all brushes through rotation, allowing simultaneous cleaning of multiple brushes without proportionally increasing system complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The rotatable nozzle holder dynamically positions the nozzle to clean multiple brushes in sequence during rotation, enabling the system to handle multiple brushes simultaneously or in rapid succession without requiring separate fixed nozzles for each brush, thus managing complexity while increasing productivity

Inventive Principle:

Principle #15Dynamics

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 device achieves thorough cleaning of brush bristles by vigorously moving cleaning fluid through them, ensuring deep penetration and efficient residue removal, with the option for simultaneous cleaning of multiple brushes.

Implementation Method 1

A jet control tube arranged in the rotatable nozzle holder, which has at least one opening. This opening is positioned so that the nozzle communicates with the interior of the jet control tube only during a portion of its rotation.

Methodology Applied

Scientific EffectFluid flow control through selective opening alignment:

Implementation Method 2

the nozzle and/or the cleaning fluid cause the hair or bristles of the bristles to move vigorously, allowing the cleaning fluid to penetrate deep into the bristles and flush away residues

Methodology Applied

Scientific EffectFluid-induced mechanical movement:
