Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If molybdenum-containing inorganic compounds are used in water soluble coating materials, then antibacterial and antifungal properties are achieved, but water solubility is very low causing precipitation over time

Engineering Contradiction:
Improveantibacterial and antifungal propertiesVSAvoidwater solubility and dispersion stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent uses a solubilizer as an intermediary substance to bridge the incompatibility between hydrophobic molybdenum-containing inorganic compounds and water-based coating materials. The solubilizer molecules have both hydrophilic and hydrophobic portions, allowing them to interact with both the inorganic particles and water, thereby maintaining uniform dispersion and preventing precipitation while preserving the antibacterial and antifungal properties

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a composite coating material system consisting of molybdenum-containing inorganic compounds combined with organic solubilizers and water-based carriers. This composite approach allows the inorganic particles to maintain their functional properties while the organic components provide water solubility and dispersion stability, resolving the contradiction between reliability and compositional stability

Inventive Principle:
Principle #40Composite materials

2Reliability

If transition metal oxide particles are used to impart antibacterial properties, then catalytic oxidation of odorous substances occurs, but particles with large surface area are required which may affect coating uniformity

Engineering Contradiction:
Improveantibacterial and catalytic propertiesVSAvoidcoating uniformity
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent controls the particle size parameters of the transition metal oxide, specifying that particles should have an average diameter of 1-100 nm. This parameter optimization ensures sufficient surface area for catalytic activity while small enough sizes allow uniform distribution in the coating, resolving the contradiction between maintaining functional properties and achieving coating uniformity

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates local high-concentration zones of transition metal oxide particles within the coating layer, where the particles are uniformly distributed at the nanoscale. This local uniformity ensures that catalytic properties are maintained throughout the coating while avoiding aggregation that would compromise overall coating quality

Inventive Principle:
Principle #3Local quality
