Power Operated Devices TRIZ Cases

Radially staggered apertures, raised rims, and deflectors deliver consistent seasoning doses with predictable spread and easier operation.

RFID communication replaces mechanical keying to verify refill cartridges, block unauthorized refilling, and support flexible dispenser sizing.

Injecting air at the outlet helps cleanly sever viscous or viscoelastic fluid streams, preventing stringing during dispensing.

A collar-and-clip bag-in-box layout keeps the container rigid when inverted, improving gravity-assisted dispensing and compact recycling.

Segmented detergent compartments and bistable actuation deliver precise dishwasher doses while avoiding lumping, stratification, and gasket friction.

A pump, tubing, and wall-piercing connector keep retail product samples sealed, cutting contamination and enabling fast container swaps.

A porous pad and bifunctional membrane guide return air, burst bubbles early, and keep ophthalmic drop volume consistent without foam.

Transparent plates with aligned semi-cylindrical slots secure coins for dual-sided viewing while protecting collectible condition.

A draw-back chamber collapses during dispensing and expands afterward to pull residual soap back, preventing spout drips and waste.

A palm vein reader and infrared thermometer let a hand cleaner dispenser verify users, track compliance, and screen for fever without contact.

Low-cost RFID reading and tag writing replace mechanical keying to verify refill cartridges, prevent unauthorized refilling, and tune dispensing cycles.

A dual-valve dome pump meters equal liquid doses while allowing backflow until intentional actuation prevents leaks and gravity dependence.
