Solution Overview

Problem

Current methods for preventing dust buildup on surfaces like fan blades and furniture are either ineffective or costly, and often require tedious cleaning processes that can be hazardous, such as climbing ladders, and may spread dust and germs.

Innovation Solution

A roller-applied coating composition that dissipates static charges and creates a smooth surface using a combination of acrylic resin, fumed alumina, PDMS, alkylolammonium salt, hydrophobic copolymer polyelectrolyte, and UV activators, which can be applied to surfaces like ceiling fan blades and furniture, reducing dust accumulation without the need for frequent brushing or washing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If conventional dust removal methods (brushing, washing) are used, then dust buildup is removed, but the process is tedious, hazardous (requiring ladder climbing), and spreads dust and germs

Engineering Contradiction:

Improvedust buildupVSAvoidcleaning process

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent applies a coating composition to the surface before dust buildup occurs, creating a protective layer that prevents dust accumulation. This preliminary action eliminates the need for subsequent cleaning operations, avoiding the hazards and inconveniences of ladder climbing and manual cleaning while preventing dust and germ spread

Inventive Principle:

Principle #10Preliminary action

2Object-affected harmful factors

If conventional dust prevention coatings are applied, then dust buildup is reduced, but the product cost increases significantly

Engineering Contradiction:

Improvedust accumulationVSAvoidproduct cost

Core Design Contradiction:

Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The patent modifies the chemical composition parameters of the coating by incorporating specific components (silicone oil, fluorocarbon polymer, quaternary ammonium compound) in optimized ratios, and controls application parameters (thin coat formulation, roller application method) to reduce material costs while maintaining effective dust prevention performance

Inventive Principle:

Principle #35Parameter changes

3Object-affected harmful factors

If frequent cleaning is performed to remove dust, then surface cleanliness is maintained, but maintenance time and safety hazards increase

Engineering Contradiction:

Improvedust buildup over timeVSAvoidmaintenance time

Core Design Contradiction:

Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The coating composition provides self-maintaining properties through its functional components: the silicone oil and fluorocarbon polymer create a low-surface-energy surface that repels dust, while the quaternary ammonium compound provides antimicrobial protection. This self-service mechanism continuously prevents dust accumulation and germ growth without requiring external cleaning interventions, eliminating maintenance time and associated safety hazards

Inventive Principle:

Principle #25Self-service

AI summary

Compositions, applications, coatings, processes of making and applying compositions and compositions for preventing dust buildup on plastic and wood surfaces such as on ceiling fan blades, portable fan blades, stand fan blades, window blinds, appliances, furniture, cabinet knobs, and drawer pulls. The compositions and coating prevent dust buildup by (1) dissipating static charges on the blades and (2) creating a very smooth blade surface that prevents dust particles getting “captured”. The coating can have a clear matte finish and contains an anti-static and high lubricity additive to deter the accumulation of dust. After applying the coating the dry time of the coatings by thin coat gravure rollers is approximately four minutes. When applied the coating can result in up to approximately 50% less dust buildup over a one week period of time.
