Liquid Transferring Devices TRIZ Cases
- Refueling Gun Detection Flap with Retractable Protrusion Detector
A refueling flap mechanism uses a retractable protrusion detector to measure gun diameter.
- Paired Flap Erroneous Fuel Feed Prevention Device
Extension portions guide paired flaps to slide and rotate together, preventing single flap malfunction during angled nozzle insertion.
- Handling Device with Independent Holding Members for Hose Routing
Independent holding members on a guide structure position multiple hoses simultaneously, eliminating manual routing strain across height differences.
- Bulk Product Dispenser with ID Tag Compatibility Verification
Automated bulk product dispenser uses ID tag verification to prevent contamination from incompatible containers.
- ATEX Additive Injection Device with External Motor and Flame-Path Seal
A compact fuel additive injection unit drives a suction pump via a drive shaft passing through an explosion-proof housing wall.
- RFID Fuel Dispenser Verification System
An RFID tag and reader exchange radio signals to verify fuel type compatibility, preventing engine damage from misfuelling.
- Fuel Port Adapter Asymmetry Prevents Avgas Misfueling
An asymmetric fuel port adapter blocks avgas nozzle insertion via interference plates, preventing engine failure from misfueling.
- Fuel Nozzle Single-Handed Hold Open Trigger Mechanism
A fuel dispensing nozzle integrates a trigger into the hand lever to enable single-handed hold open operation.
- Fuel Dispenser Test Port With Quick Connect Fitting
Relocating the test port to a high line entry point allows safe pressure relief and testing without removing impact shear valve plugs.
- Reservoir Pump Air Venting to Prevent Hydrolock
A reservoir pump introduces ambient air during suction strokes to maintain compression volume.
- Fuel Dispenser Octane Blending with Residual Volume Compensation
A fuel dispenser blends component fuels using sensors to maintain target octane levels during dispensing events.
- Pre-Tank Fuel Filter for Particulate Removal
A pre-tank fuel filter screens particulates from hydrocarbon fuel before it enters the vehicle tank.
- Magnetic Plastic Filling Head for Liquid Tank
A filling head uses a magnetic plastic element to trigger an automatic pump nozzle mechanism.
- Bottle Attachment Mechanism With Rotating Slot For Secure Coupling
A bottle attachment mechanism uses a rotating slot to couple accessories securely.
- Funnel Cap With Sliding Collar For Spill Prevention
Sliding collar vents allow air escape while preventing liquid spillage during transfer.
- Lever Charging Non-Aerosol Sprayer with Flexible Cable
A lever charging element coupled to a spring biased piston via a flexible cable drives liquid through an integrated spray head.
- Fuel Station Vehicle Conveyor for Continuous Refueling
A vehicle conveyor transports cars to a stationary fueling nozzle while a slide mechanism maintains the hose connection.
- Pressure Control Device Scavenger Gas Migration
A pressure control device incorporates a scavenger in the chamber to capture migrating gases, maintaining stable equilibrium and preventing composition changes.
- LNG Connection Device Segmentation and Flushing Gas Mechanism
Segmented buffer spaces with inert flushing gas prevent explosive atmosphere formation while dual valves maintain sealed passages.
- Hose Puller With Locking Grip for Ergonomic Handling
A hose puller with a laterally-extending grip and lock mechanism secures the nozzle assembly for manual pulling.
- Lock-out Device Mating Concentric Rings Dispenser
Concentric ring projections and recesses prevent incorrect chemical package engagement, eliminating costly unique bottle shapes.
- Modular Fuel Changing Device With Interchangeable Adapters
A plunger-based fuel changing device uses interchangeable adapters to connect various fuel pipes and cans for quick transfer.
- Snap-On Adapter With Guidance Recesses For Easy Twist-Off Refill
A snap-on adapter uses guidance recesses to secure containers and enable easy twist-off removal.
