Single-Unit Apparatus TRIZ Cases

Discharge guide groove channels internal pressure outward, preventing hydrogen gas infiltration into electronic components.

A dispensing atomizer integrates a puncture mechanism to release concentrated cleaning solution from an internal capsule into a reservoir.

Locking means hold the deformable membrane in a fixed squeezed position, preventing unintended dispensing and preserving elasticity during storage.

A battery assembly with dedicated connection terminals ensures stable electrical contact between the battery poles and the built-in circuit board.

A dispensing device couples a daughter bottle into a mother bottle recess to enable single-force actuation of the refill mechanism.

Copper-coated dispensing head walls prevent bacterial proliferation without preservative migration into pressurized cosmetic formulations.

A dispensing device joins plastic layers via plasma pretreatment and bi-injection to create a tight chemical bond.

A lateral actuator system uses a guide surface to move the dispenser member.

A pump dispenser chaplet uses a rotating ring with a cut-out arc to allow controlled actuator rotation before unscrewing.

An elastically deformable pusher wall opens the outlet valve during priming, allowing trapped air to escape from small reservoirs without pressurization.

Variable cross-section geometry in polyolefin arms prevents yielding while maintaining recyclability.

A detachable stop element limits delivery valve excursion, preventing cover-induced malfunctions and ensuring reliable pre-compression.

An oblong collar with integrated fins thermally bonds laminated film sheets, preventing air entry through irregular weld zones.

Radial edges on a hollow piece engage piston shoulders to move a shutter, balancing vacuum levels to prevent blockage.

Lateral tip movement actuates the pump assembly, eliminating cumbersome axial pressing for easier application.

Radial cup support reduces axial dimension while maintaining sealing reliability through segmented structural constraints.

A refillable fluid dispenser separates the pump from the inner container to enable simple refilling.

Relocating the disc valve to the center sleeve eliminates vertical interference, reducing container thickness while maintaining reliable liquid ejection.

A pump dispenser container features a recessed bottom area that collects residual liquid for efficient extraction by the riser pipe.

Friction-based rotation of the trim sleeve resolves contradictions between seal crushing torque and face alignment precision.

A refillable fluid dispenser uses a dedicated venting passage to allow air escape during refilling.

Spring-loaded arms bias a plug against a seat to close the discharge path, preventing foam drooling and eliminating product waste.

A push button dispenser injects air into a spray zone to form fine aerosol droplets.

An ergonomic container appendage segments the handle to conform to hand anatomy, reducing fatigue during prolonged spray bottle operation.

A linear piezo-motor drives a positive displacement pump to deliver precise liquid volumes.

A quantitative dispensing device uses a press button and elastic cap to expel air and create suction for precise material intake.

An integrally molded applicator head combines elastic valves and an actuating handle into a single structural unit.

Segmented outer and inner containers preserve intermediate storage space while enabling simultaneous mixing of different cosmetic materials.

A discharge piston enters an undersized inlet opening to define the start of the delivery stroke.

A fluid dispensing device uses lateral actuation to move a piston via flexible side levers.

A refillable fluid dispenser uses a removable collar and intermediate element to swap inner containers.

An articulated pawl coupled to a locking handle restricts actuator mobility, preventing accidental operation while minimizing structural complexity.

A movable visual indicator shifts position via fluid pressure to confirm actual dose delivery, preventing false feedback when mechanical actuation fails.

Rotatable handles adjust valve guide positions to precisely control dispensing amounts and prevent premature mixing of separate contents.

Segmented housing reduces device volume, allowing refills to share retail shelves while ensuring secure engagement.
