Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If melamine foam is used to remove soils and stains from hard surfaces, then cleaning effectiveness is improved, but durability upon use deteriorates due to foam crumbling into small particles

Engineering Contradiction:
Improvecleaning effectivenessVSAvoiddurability upon use
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The invention combines melamine foam with abrasive particles to create a composite cleaning implement. The abrasive particles are embedded within the foam matrix, creating a material that leverages both the mechanical cleaning action of the foam and the abrasive cutting action of the particles, thereby improving durability while maintaining cleaning effectiveness

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The invention modifies the physical and chemical parameters of the cleaning implement by incorporating abrasive particles with specific size ranges (0.01-45 wt%) and particle diameter (5 µm to 3 mm) into the melamine foam structure, changing the material properties to achieve both effective cleaning and improved durability

Inventive Principle:
Principle #35Parameter changes

2Reliability

If substantial amounts of solvent are used with melamine foam, then soil and stain removal performance is improved, but water consumption increases

Engineering Contradiction:
Improvesoil and stain removal performanceVSAvoidwater consumption
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The invention changes the cleaning mechanism from relying on solvent saturation to utilizing abrasive particle action, allowing effective cleaning with reduced water consumption. The abrasive particles enable mechanical removal of soils and stains through friction and cutting action rather than requiring substantial solvent penetration

Inventive Principle:
Principle #35Parameter changes

3Reliability

If abrasive particles are incorporated into melamine foam, then durability and cleaning performance are improved, but manufacturing complexity increases

Engineering Contradiction:
ImprovedurabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention merges the fabrication of melamine foam with the incorporation of abrasive particles into a single integrated manufacturing process. The abrasive particles are added to the foam precursor mixture before curing, allowing both the foam structure and abrasive reinforcement to be created simultaneously rather than requiring separate assembly steps

Inventive Principle:
Principle #5Merging (Combining)
