Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual cleaning methods are used to remove debris from cutting members, then cleaning action is provided, but cutting edges become dull faster and cleaning reliability is insufficient

Engineering Contradiction:

Improvecleaning operationVSAvoidcleaning reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent employs a vibrating component that generates vibrations transmitted through a structural element to the cutting members. This mechanical vibration creates relative motion between the cleaning component and cutting members, enabling effective debris removal without direct contact with cutting edges, thus maintaining cutting sharpness while improving cleaning reliability

Inventive Principle:

Principle #18Mechanical vibration

Solution Approach 2:

The patent introduces a structural element as an intermediary between the vibrating component and the cutting members. This intermediary transmits vibrations to the cutting members indirectly, allowing cleaning action to be applied without the cleaning component directly contacting the cutting edges, thereby preventing dulling while ensuring thorough cleaning

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If manual cleaning is performed repeatedly, then debris removal is attempted, but cutting member lifespan is reduced due to accelerated dulling

Engineering Contradiction:

Improvecleaning effectivenessVSAvoidcutting member lifespan

Core Design Contradiction:

ProductivityVSDuration of action of moving object

Solution Approach 1:

The vibrating component generates controlled vibrations that facilitate debris removal from cutting members through vibrational motion rather than direct mechanical scraping. This reduces wear on cutting edges while maintaining cleaning effectiveness, thereby extending cutting member lifespan

Inventive Principle:

Principle #18Mechanical vibration

Solution Approach 2:

The patent replaces traditional manual mechanical cleaning (brushing or wiping) with a vibration-based cleaning mechanism. This substitution eliminates the need for direct mechanical contact between cleaning tools and cutting edges, reducing wear and extending the functional life of cutting members while maintaining high cleaning effectiveness

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If cleaning components directly contact cutting members, then debris removal is enhanced, but cutting edges dull faster

Engineering Contradiction:

Improvedebris removal efficiencyVSAvoidcutting edge dulling

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The structural element serves as an intermediary that transmits vibrational energy to the cutting members without requiring direct contact between the cleaning component and cutting edges. This indirect coupling enables effective debris removal through vibration while preventing mechanical wear that would dull the cutting edges

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The vibrating component generates mechanical vibrations that are transmitted to the cutting members through the structural element. This vibrational action loosens and removes debris from cutting members without requiring direct mechanical contact, thereby eliminating the harmful dulling effect while maintaining high debris removal efficiency

Inventive Principle:

Principle #18Mechanical vibration
