Single-Unit Apparatus TRIZ Cases

A flexible housing ejector mixes and dispenses substances through mechanical compression without volatile organic compounds.

A trigger dispenser head integrates a flexible membrane and check valve to resolve the contradiction between structural simplicity and dispensing repeatability.

A lateral actuation system for nasal spray dispensers uses a radial projection and guide surface to manage mechanical forces during operation.

A dispensing pump reserve mechanism isolates a product supply to alert users of imminent depletion.

Segmented pump devices with dedicated controllers reduce downtime during component failure and simplify application conversion.

A dispensing head integrates the trigger and return spring into a single thermoplastic component.

A dispenser uses a top-mounted bulb to suspend solids in a straight downward pathway, preventing clogging and enabling precise single-handed application.

Segmenting the cup-shaped body and piston allows easy separation of materials, resolving the trade-off between device functionality and recyclability.

An inclined guide and wiper system automate suction to prevent residue waste and user contamination.

A fluid dispenser head uses a flexible deformable zone to connect the peripheral skirt, bearing surface, and dispensing orifice.

A spray head assembly uses a piston and check valve to recapture nozzle liquid via suction, preventing leakage during transport.

A bi-material fixing ring uses a flexible outer layer to enhance radial tightening on a tank neck hoop, eliminating costly machining operations.

Merging the nozzle and filling opening onto one face simplifies the refillable fluid dispenser while maintaining sealing integrity.

A hand-held sprayer features a rotatable spray lance assembly driven by a rotary axle base and rotating shaft to enable compact folding.

A pump actuator nozzle uses a reinforcing ring to enhance mechanical resistance against rotation.

Flexible tabs and an auxiliary tooth maintain torque resistance across multiple openings, reducing decay from 300 Nm to 150 Nm after five cycles.

An annular sleeve and valve element control air delivery within the housing, resolving metering accuracy versus manufacturing complexity.

A rotatable body insert with an undulating annular vent-control bead seals the pump vent path during transit.

Segmented sealing elements prevent water dilution while avoiding part seizing caused by tight tolerances.

Elastic connecting pieces on a controlling component substrate bridge the battery and atomizing parts, resolving compatibility issues with new components.

Segmented pumps and one-way valves enable single-actuation refilling while preventing spillage and actuator damage.

A spray canister dispenser housing features a moveable plate that compresses the aerosol actuator for secure attachment.

A multilayer fluid bag uses a rigid neck and valve to create a vacuum seal.

A refillable dispenser uses a push-button actuator to drive an elongated mixing rod for solution homogenization.

A sprayer clip with an arm channel receives a container handle to enable quick snap-fit attachment and detachment.

Radially movable bending rollers on a rotatable base adjust via a spring-loaded lever to prevent foaming and ensure gastight seals in inhaler cartridges.

Gadroons on the collar maintain pump alignment during deformation, resolving instability from dip tube forces.

A trigger pump dispenser uses a cam and cam follower to convert pivoting motion into linear piston movement for fluid spraying.
