Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If metal grating disk with spikes is used, then grinding effectiveness is improved, but safety and ease of cleaning deteriorate

Engineering Contradiction:

Improvegrinding effectivenessVSAvoidsafety hazards from sharp edges

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the material parameter from metal to plastic, fundamentally altering the properties of the grating disk. This material substitution eliminates sharp edges while maintaining the spike structure, thereby resolving the safety hazard without compromising grinding effectiveness

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses a composite structure combining plastic material with integrated spike features. The plastic base material provides safety and ease of cleaning, while the molded-in spikes provide the necessary mechanical action for effective grinding

Inventive Principle:

Principle #40Composite materials

2Strength

If metal grating disk with stamped spikes is used, then structural strength is improved, but ease of cleaning deteriorates

Engineering Contradiction:

Improvestructural strengthVSAvoidease of cleaning

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The patent changes the manufacturing method from stamping to molding, which fundamentally alters the surface geometry. The molded-in spikes create smooth transitions without crevices, eliminating food trapping areas while maintaining structural integrity through the molding process

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

Instead of creating spikes by removing material (stamping), the patent forms spikes by adding material through molding. This inverted approach creates smooth, crevice-free surfaces that are easily cleanable while maintaining the necessary spike structure for grinding

Inventive Principle:

Principle #13The other way round (Inversion)
