Male Contraceptives TRIZ Cases

See how segmented cushion layers with differentiated materials and rotatable components provide

UV or visible-light photoinitiators crosslink latex without ionizing radiation or sulfur accelerators, reducing irritation and process complexity.

Fatty acid esters from glycerol formal replace aromatic oils in elastomers, improving tire tread compatibility, winter grip, and abrasion resistance.

Fatty acid esters from glycerol formal replace aromatic oils in elastomers, improving rubber compatibility without exudation or PAH-related risks.

A flexible skirt and rigid base improve penile urine collection comfort and fit while reducing leaks through conformal attachment and suction.

A multilayer collection bag uses notches, elastic sheets, and sealed strip regions to stay attached on curved skin and block fluid leakage.

Varying-elasticity compression zones and an absorbent layer secure the sleeve discreetly while managing male incontinence comfortably.

Polyhydric alcohols and sugars in an aqueous condom lubricant preserve transparency during storage while lowering osmolality and tissue damage risk.

SIS latex replaces sulfur, zinc oxide, and diphenyl guanidine to maintain strong glove and condom tensile properties with lower allergy risk.

An adhesive inner surface, grip tabs, and a one-way latex valve improve fit, removal, and fluid retention in a male contraceptive.

Bilayer-encapsulated plant stem cells add lasting skin care to elastomeric gloves without weakening barrier strength or comfort.

Blending natural and synthetic latex with sulfur donors enables thin elastomer films that stay soft while maintaining tensile and tear strength.

Internal annular ribs create directional blood flow resistance, limiting venous outflow while preserving inflow to help maintain erection pressure.

An anchored urethral sleeve uses a balloon and fluid reservoir to prevent release while preserving partner sensation and reducing slip risk.

SIS latex replaces sulfur and zinc oxide to produce thin elastomeric gloves and condoms with strong tensile properties and fewer allergens.

Controlling zinc in natural rubber latex below 60 ppm limits gel formation, improving thin condom electronic test yield and reducing waste.

Okra mucilage replicates cervical mucus stretchiness and selective sperm permeability without limited natural collection windows.

An okra mucilage extract replicates cervical fluid behavior for sperm selection and storage while adding antiviral protection without limited collection windows.

A layered adhesive sheath adds a tactile stimulus pad to maintain fit, comfort, and pathogen barrier protection during oral sex.

Non-water-soluble silicone oil stabilizes warming, cooling, and tingling agents on polyisoprene condoms while limiting irritation.

Repeated dipping and drying of anionic waterborne polyurethane improves condom softness and raises burst volume beyond typical polyurethane limits.

Selective adhesive fixation on the penis head preserves natural sensation while maintaining contraceptive and STI barrier protection.

A sulfonated waterborne polyurethane adhesive layer bonds latex and polyurethane layers, preserving thinness and flexibility without delamination.

A stereoscopic oral barrier uses an elastic membrane and tongue pocket to block bodily fluids and reduce STI transmission during oral sex.

A low-modulus polyurethane adhesive layer combines thin construction with improved flexibility and strength in a pure polyurethane condom.

An air-permeable sheath region and air-impermeable barrier create a vacuum pathway for erectile dysfunction therapy while retaining condom protection.

Water-organic solvent casting and swelling-agent treatment form elastic polyurethane hydrogel films for durable, biological-agent-impervious condoms.

An inner absorbent region cleans and exfoliates the penis while the flexible tubular body contains semen and provides a contraceptive barrier.

Boron nitride particles in polymer latex improve elastomeric article heat conduction and lubricity while maintaining tensile strength.

Separate condom and ring purchases are consolidated into one kit with multiple ring diameters, simplifying access and sizing selection.

Hyperosmolar lubricants can damage epithelial cells; controlled osmolality and pH support vaginal microbiota while preserving comfortable, lasting lubrication.

Hot-water or cold-extracted okra mucilage provides clear artificial cervical fluid for sperm preservation, motility testing, and antiviral protection.

A two-stage accelerator process crosslinks synthetic polyisoprene latex while limiting nitrosamines and preserving condom strength and tear resistance.
