Membranes TRIZ Cases

Multi-stage filtration purifies windshield washer fluid into high-purity methanol suitable for direct use in fuel cell systems.

Segmented filtration using a homogeneous polyamide depth filter prevents membrane blockage and particle release while maintaining high flow capacity.

A polyamide hollow fiber membrane achieves high water permeability through controlled methylene to amide group ratios.

An integrated sealing well in the manifold secures the cassette, preventing leakage from layer misalignment during user assembly.

A porous membrane laminate uses PTFE with controlled surface roughness to achieve high fiber density for microparticle capture.

Segmenting the membrane into multiple leaves reduces pressure drops and increases permeate flow capacity in reverse osmosis cartridges.

A polymer solution combines high-performance polymers with N-tert-butyl-2-pyrrolidone and a water-soluble polymer to form membranes.

Discrete support bars hold a thin-film oxygen separation membrane to prevent sorbent abrasion and dust formation while improving maintenance behavior.

Graphene oxide particles adsorb pollutants before passing through a hollow fiber membrane to block the adsorbent and release clean water.

Amino-functional additives create covalent bonds between cellulose acetate and polyimide layers, preventing delamination under dialysis pressure.

A composite membrane uses polyethylene imine coating and poly(hexamethylene biguanide) grafting to enhance surface properties.

Tangential flow ultrafiltration replaces time-consuming dialysis to produce high-concentration silk fibroin with controlled molecular weight.

A liquid composition mixes silicon alkoxide hydrolyzate with fumed silica sol to form a porous film.

A hybrid inorganic-organic polymer membrane incorporates uniformly distributed metal cations to enhance proton conductivity.

Direct coating of separation layer on silicon carbide support eliminates intermediate steps, boosting flux by 30% while maintaining mechanical strength.

Plasma vapor deposition of precursor monomers forms non-crosslinked membranes with high ionic conductivity, avoiding S-O bond degradation.

Depositing precursor mixtures into specific regions creates mesoporous membranes with complex functional architectures.

Flexible seals decouple block expansion while distributor elements ensure uniform flow, enabling accurate kinetic measurements without complex fixed structures.
