Single-Unit Apparatus TRIZ Cases

A manual pump maintains a hermetic seal between the hollow stem and ring cap to prevent fluid leakage.

A decanting system aligns liquid and air passages to transfer fluid between a refill and bottle.

A nasal fluid dispenser uses a gravity-fed metering chamber to eliminate priming delays and ensure immediate full-dose dispensing.

Segmented sealing components prevent ethanol diffusion from volatile drug containers, maintaining formulation concentration under varying climatic conditions.

Segmented reservoirs isolate ethanol from microcapsules, preventing premature release and extending fragrance noticeability for up to 11 hours.

A rigid nebuliser container uses a direct aeration channel to compensate internal pressure without complex inner bags.

Symmetric actuating arms transmit force through film hinges to prevent jamming and finger pinching in fluid dispensers.

Soft plastic support members deform under pressure to reduce friction with hard covers, enabling effortless removal while absorbing handling shocks.

Segmented C-shaped safety element absorbs impact shocks and prevents rotation to protect manual pump dispenser from strain.

A locking member secures the valve stem during tappet reinstallation to prevent fluid leakage in refillable dispensers.

A dispensing container uses a sump and draw tube to maintain positive liquid pressure in the nozzle.

Segmenting the integral valve element into independent zones resolves low-pressure leakage while maintaining reliable seal integrity.

Segmented rotating sleeve prevents child access to pump button without adding complex internal mechanisms.

Segmenting the spring element into distinct functional sections resolves contradictions between device complexity and reliable discharge of viscous materials.

A fluid dispensing device uses a flexible shell container and movable discharge members to expel liquid doses while maintaining an air-tight seal.

A liquid dispensing device uses a separate prime valve for efficient priming and a dome outlet valve to control output pressure.

Elastic membrane maintains dispensing pressure by sealing against frame leaks.

A trigger sprayer lever mechanism drives a piston to compress liquid through a rotating nozzle.

Nested dispenser tube sections rotate relative to each other to shift between open and closed positions without axial movement.

A fluid dispensing head uses a double-walled actuating ring to guide a mobile cover and lock the push member.

A polypropylene trigger sprayer uses a pre-compression diaphragm to deliver uniform fluid dispensing.
