Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional materials are stacked and adhered by glue through baking and heating, then the cleaning cloth can be formed, but thermal expansion and contraction cause concave and curled shapes with air bubbles

Engineering Contradiction:

Improvemanufacturing processVSAvoidflatness and bubble-free surface

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent uses a composite structure consisting of a non-woven fabric base layer and an abrasive layer bonded together. This composite material approach eliminates the need for separate adhesive layers and complex stacking processes, preventing thermal deformation and air bubble formation while maintaining manufacturing efficiency

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent removes the adhesive layer from the manufacturing process entirely. Instead of stacking and adhering multiple material layers with glue, the abrasive layer is directly bonded to the non-woven fabric base layer through a simplified process that eliminates the adhesive intermediate layer, thus avoiding the thermal expansion mismatch that causes curling and air bubbles

Inventive Principle:

Principle #2Taking out (Extraction)

2Strength

If conventional probe cleaning cloths are produced with hard materials, then durability is improved, but the production becomes time-consuming and labor-intensive

Engineering Contradiction:

ImprovedurabilityVSAvoidproduction efficiency

Core Design Contradiction:

StrengthVSProductivity

Solution Approach 1:

The patent replaces complex mechanical stacking and adhering operations with a simplified direct bonding process. The abrasive layer is applied and bonded directly to the non-woven fabric base layer in fewer steps, reducing labor intensity and production time while maintaining product durability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent divides the cleaning cloth into two functional layers: a non-woven fabric base layer providing structural support and durability, and an abrasive layer providing cleaning functionality. This segmentation allows each layer to be optimized independently and bonded together through a simplified process, improving both durability and production efficiency

Inventive Principle:

Principle #1Segmentation

3Strength

If conventional probe cleaning cloths are produced with hard materials, then durability is improved, but the materials are easily damaged

Engineering Contradiction:

ImprovedurabilityVSAvoidresistance to damage

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The patent creates a composite structure where the non-woven fabric base layer provides toughness and damage resistance, while the abrasive layer provides durability for cleaning functions. The combination of these materials with different properties achieves both durability and resistance to damage without the brittleness of purely hard materials

Inventive Principle:

Principle #40Composite materials
