Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional stirring and cleaning methods are used, then the cleaning machine structure is simple, but the cleaning effect of plastic chips does not reach the expected effect

Engineering Contradiction:

Improvecleaning effectVSAvoidcleaning machine structure

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies ultrasonic vibration technology to clean plastic chips. Ultrasonic vibrators generate high-frequency mechanical vibrations that create cavitation bubbles in the cleaning solution, which implode to produce micro-jets that effectively remove contaminants from chip surfaces and internal gaps, significantly improving cleaning effect compared to traditional stirring methods.

Inventive Principle:

Principle #18Mechanical vibration

Solution Approach 2:

The patent replaces the traditional mechanical stirring cleaning system with an ultrasonic vibration-based cleaning system. This substitution uses acoustic energy and cavitation effects instead of mechanical agitation, achieving superior cleaning effectiveness while maintaining a relatively compact device structure.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of manufacture

If traditional cleaning methods are used, then the device structure is simple, but the cleaning cost increases

Engineering Contradiction:

Improvedevice structureVSAvoidcleaning cost

Core Design Contradiction:

Ease of manufactureVSLoss of substance

Solution Approach 1:

The ultrasonic vibration method achieves thorough cleaning in a single pass by creating intense cavitation effects throughout the cleaning solution. This eliminates the need for multiple cleaning stages or repeated processing, thereby reducing overall cleaning costs despite the addition of ultrasonic vibrators to the device.

Inventive Principle:

Principle #18Mechanical vibration

3Manufacturing precision

If traditional stirring cleaning is used, then the cleaning machine is simple to operate, but it cannot clean internal gaps of plastic fragments effectively

Engineering Contradiction:

Improvesurface cleanlinessVSAvoidoperation simplicity

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

Ultrasonic vibrations generate cavitation bubbles that penetrate into internal gaps, crevices, and porous structures of plastic chips. The implosion of these bubbles creates micro-shockwaves and jet streams that effectively dislodge contaminants from hard-to-reach areas, achieving comprehensive cleaning of both surfaces and internal structures.

Inventive Principle:

Principle #18Mechanical vibration
