Single-Unit Apparatus TRIZ Cases

Segmented cannula support bore with reduced internal diameter prevents liquid leakage into the central axial bore, ensuring accurate fluid product dispensing.

An integrated inlet valve chimney with a flexible exhaust membrane increases suction force for viscous products by optimizing the compression ratio.

Segmented venting openings allow trapped air escape while the shutter remains closed, preventing fluid loss and ensuring reliable first-actuation filling.

Modular fixed nozzle pumps dispense viscous fluids while simplifying cleaning and preventing nozzle dripping.

A refillable cosmetic container uses a detachable body and pumping mechanism to dispense liquid cosmetics efficiently.

A rotatable operating cap engages fins with base cap slots to enable or block aerosol dispensing via tilting action.

A pump dispenser base structure guides air to a peripheral pocket region adjacent the wall to purge trapped gas from the inlet.

Segmented cover elements engage via backlash compensation to eliminate clearance gaps between the cap and reservoir wall, preventing foreign body intrusion.

A discharging device uses a locking element coupled to the manual actuator to block liquid delivery when the cap is in its safety position.

Replacing rigid bottles with thin film pouches reduces plastic consumption and allows empty containers to flatten for easier disposal.

A dispenser uses interchangeable limiting elements to adjust the pump stroke and control dispensing quantities.

A trigger sprayer design stores pressurized liquid during the charge stroke for continuous discharge during the return stroke.

An adapter with a bendable segment and plunger translates tilting motion into linear compression.

Embedded malleable wires in a flexible tube retain user-bent shapes, enabling self-application of materials to hard-to-reach body areas without assistance.

An air pump creates positive pressure in a storage container to move pasty medium, avoiding complex pressurized vessel requirements.

A sliding-jacket pump uses a sleeve and lower valve to ensure tightness and accurate dosage.

Chamfered projections on an actuation ring guide lateral lever movement into safe axial displacement, preventing nozzle injury and simplifying assembly.

A valve cup follows a step-like housing contour to seal the stem and cup interface, reducing gas loss and water vapor ingress in pressurized containers.

A fluid dispenser uses a gravity-driven movable outlet member to direct flow between spray and application ports based on orientation.

A snap-fit cartridge release mechanism opens reservoirs via elastic deformation during cap tightening.

A multi-directional fluid pumping device uses segmented feed tubes with gravity-driven plugs to access reservoir contents from any orientation.

Telescopic housing members compress a resilient foam reservoir to release fragrance vapor, preventing leakage and extending useful life.

A pump mechanism uses a single piston to control fluid channels for viscous substance delivery.

Segmenting the vent valve from the bulb resolves rigidity constraints, allowing rapid air entry while preventing liquid leakage.

Segmented dispenser head joins auxiliary body and frame to aspirate liquid, resolving assembly complexity from asymmetric components.

Slanted sliding grooves convert rotation into axial motion to expose the outlet, reducing structure complexity and manufacturing costs.

A plastic fluid dispenser uses a concertina-like deformable element to dose liquid and pull air into the bottle during operation.
