Fouling Prevention TRIZ Cases
- Microstructured Curved Surfaces for Mold Release
Parallel alignment of structuring elements resolves the contradiction between mechanical stability and demoldability on complex geometries.
- Semiconductor Substrate Liquid Film Chuck for Backwash Prevention
A liquid film chuck supports substrates via fluid layers while gas pressure blocks backwash from reaching non-processing surfaces.
- Multi-layer Waste Liquid Containment with Oil Separation
A multi-layer waste liquid containment system uses perforated upper plates and netting to capture oils from wash water.
- Variable-Flow Emitter with Deformable Membrane for Anti-Clogging
A variable-flow emitter uses a deformable elastomer channel to adjust water output based on pressure changes.
- Slippery Rough Surfaces for Droplet Mobility
A textured substrate with a conformal lubricant layer maintains liquid repellency across wetting states.
- Automated Cleaning System for Chemically Etched Metal Substrates
An automated cleaning system uses sprayers, brushes, and air knives to remove residues from chemically etched metal substrates without manual intervention.
- Hydrophobic Coating for Agricultural Sprayer Tank and Pipe Systems
A hydrophobic coating applied to tank and pipe interiors sheds residual liquid and dirt, reducing surface contamination in agricultural sprayers.
- Barnacle Larvae Settlement Suppression via Specific Blue Light Irradiation
Targeting 409 to 412 nm wavelengths suppresses barnacle larval settlement by inducing negative phototaxis, reducing clogging in water intake systems.
- Concrete Chute Washout System with Detachable Rack
A detachable container unit and rack system collect rinse water from concrete chutes without bulky hydraulic components.
