Liquid Spraying Apparatus TRIZ Cases

U-shaped battery cage webs open five sides for direct cooling in portable sprayers, preventing energy store overheating while keeping secure retention.

An electromagnetic valve synchronized with blower operation closes the liquid feed pipe at shutdown to prevent mist blower leakage.

An annular seal and rigid casing shift retention outward to reduce transducer damping and improve membrane-driven aerosol droplet dispersion.

An angled inlet-outlet chamber and sealed third opening cut paint sprayer noise while preserving airflow and control-board heat dissipation.

A removable nozzle with laminar flow channels cuts splashing, soiling, and downtime in polyurethane spray can filling.

A level-controlled container and directed nozzles keep water circulating to clean airless sprayers thoroughly while reducing refills and water use.

A rotatable spray head and sliding clamping piece keep water flowing without constant trigger pressure, reducing hand fatigue and joint strain.

LEDs built into the pressure washer gun light the spray stream while audio and haptic feedback make cleaning more visible and engaging.

Compressed gas replaces electric vibration to keep the powder spray gun sterilizable while maintaining smooth, uniform powder dispersion.

A ratcheting spool locks and tensions the hose to prevent unwinding while enabling controlled deployment on portable washers and compressors.

An underbody battery bracket powers the pump without wall outlets while the sprayer body and stand shield the battery from overspray.

A venturi atomizer and fan use forced air to disperse volatile liquid while reducing residue on outlets and nearby surfaces.
