Liquid Dispensing TRIZ Cases

Replacing metal with HDPE eliminates splinter hazards while maintaining structural strength.

A beverage tapping device integrates cooling means to maintain a microbiological climate below 15°C.

Ratchet-pawl engagement prevents catastrophic depressurization by securing threaded valves against reverse rotation in plastic aerosol containers.

An expandable expansion device generates pressure inside a beverage keg to maintain consistent carbonation levels and prevent foaming during dispensing.

A mounting cup and flange use complementary springy shapes for snap-together fitting of an aerosol valve.

An annular cutout on the chamber insert upper edge preserves seal width, preventing blockages from propellant-induced swelling.

Segmented cap geometry creates radial undercuts that prevent axial detachment of the dispenser during tilting valve actuation.

Separate lines and valves manage beverage and foam flow, resolving manual operation inconsistencies.

A metered valve system delivers precise coolant doses via a single-handed applicator head for controlled tissue freezing.

A regulator cap assembly integrates a gas reservoir and pressure valve to maintain beverage carbonation.

Segmented stem construction and elastic diaphragms prevent moisture ingress that hardens prepolymers, ensuring reliable sealing in assembly foam valves.

A monolithic spray cap merges the locking and actuating members into a single pivotable component for simplified assembly.

Varying radii in the curl portion distribute pressure uniformly, preventing gasket extrusion during clinching.

Circumferential cutting of the inner vessel eliminates unused substance residue, reducing disposal costs and improving actuation reliability.

Limiting valve stem compression to 85% of the reference point prevents deformation and leakage while maintaining filling productivity.

Electronic display screen organizes beverage categories and modifier icons to simplify custom drink selection.

A beverage dispensing system stores acid and flavor concentrates in separate containers to mix components on demand through a single nozzle.

Segmented ring design with an elastically deformable axial wall prevents valve body deformation and product contamination by absorbing radial assembly stresses.

An automated Clean-In-Place unit cleans beverage dispensing lines using ozonated water and pressurized gas without manual disassembly.

A flavor infusion dispenser uses a magnetic switch to control pump activation for precise beverage mixing.

A spray head uses a snap-action coupling to lock the inner body, preventing accidental liquid discharge.

Transparent housing enables visual identification of contents while the leaf spring latch prevents accidental discharge during actuation.

Segmented elastomeric gasket vents overpressure in beverage containers while visible shape changes indicate valve activation.

A keg connector uses a single lever to drive dispense and gas tips into sealed openings for firm coupling.
