Liquid Dispensing TRIZ Cases
- Aerosol Base System Preventing Propellant Stranding
Inverted base system stores viscous aerosols with propellant headspace above product, preventing premature gas discharge and ensuring complete delivery.
- Hinged Flap Closure for Liquid Container Pressure Equalization
An integrated hinged flap on a resilient tapping bush controls pressure equalization while preventing contamination in liquid container closures.
- Beverage Dispensing System with Audio Video Feedback
A beverage dispensing system presents audio and video files during liquid output to guide user interaction.
- Spray Cap Lateral Actuation Cam Mechanism
Lateral actuation via a rolling cam resolves ergonomic handling conflicts while preserving precise dosing control through dynamic pivoting.
- Spray Cap Flexible Hinge Reduces Actuating Force
An elastomeric hinge in the tubular member reduces operational force and friction while maintaining stem alignment.
- Beverage Dispensing Unit Pressure Control
A beverage dispensing unit integrates a gas container and pressure regulating means to control propellant flow.
- Beverage Extraction Device with Sloped Disengagement Clamp
A beverage extraction device uses a sloped container engagement surface to radially disengage the clamp from the bottle neck during upward movement.
- Gravity Tube Filler Control Valves for Precise Fill Levels
Throttling control valves reduce hydrostatic pressure rise in return air pipes, eliminating vacuum correction needs.
- Valve Holding Device for Pocket Refill with Degassing Holes
A valve holding device for pocket refill uses degassing holes and a semi-permeable membrane to manage gas release from volatile products.
- Rotating Collar Cap Prevents Product Build-Up
A rotating collar cap with a removable tab minimizes rotation before removal, preventing product build-up around the aperture.
- Fluid Dispenser Weight Roller Crease Prevention
Stabilized weight roller overcomes bag creases to achieve 98% emptying rates.
- Contactless Beverage Dispenser Interface Using Optical Detection
Optical sensors detect user presence in a specific zone to trigger liquid dispensing, eliminating germ transmission from shared surfaces.
- Gravity-Assisted Beverage Container Installation
Sloped surfaces guide heavy collapsible beverage containers into dispensing systems, eliminating manual lifting forces and preventing pipe damage.
- Conductivity Sensor for Beverage Dispenser Ingredient Detection
Replacing mechanical pressure sensors with electrical conductivity measurement eliminates acid damage and false empty detections in beverage dispensers.
- Fluid Dispenser Limited Thrust Mechanism
A fluid dispenser head uses a limited thrust member and cam means to decouple pusher duration from valve stroke, ensuring reproducible metered dosing.
- Metered Liquid Dispensing via Spherical Piston
Spherical pistons move by fluid pressure to dispense precise liquid volumes without volatile propellants.
- Laser-Welded PET Fluid Dispenser for Recyclability
Homogeneous PET construction and laser welding resolve the trade-off between high-pressure seal reliability and full recyclability.
- Crystallized Plastic Valve Housing for Aerosol Dispensers
Crystallization treatment stabilizes the plastic valve housing dimensions under temperature variation, preventing propellant leakage from non-concentric seals.
- Dispensing Actuator Alignment via Flexible Overcap Pivoting
A dispensing actuator aligns with the orifice using a flexible overcap that pivots during operation.
- Cylindrical PET Vessel with Spherical Dome for High-Pressure Control
A cylindrical high-pressure plastic vessel uses a spherical dome to withstand internal forces.
