Hair Drying TRIZ Cases

Segmenting the base from the cover resolves the trade-off between structural complexity and versatile airflow distribution.

Centrifugal fan hair dryer uses optimized rotor blades and peripheral inlet to reduce noise while maintaining air flow.

Segmenting the air inlet from the folding joint maintains fluid flow continuity, eliminating wind loss when the accessory is folded.

A portable hair dryer uses a perpendicular fan axis to balance the motor module and reduce dynamic vibration during operation.

Segmented air inlet elbow blades reduce turbulence and noise levels without increasing device weight or manufacturing cost.

A hair dryer nozzle uses a secondary channel to draw ambient air, thermally insulating the outer surface for safer handling.

An oval drying chamber cross-section spreads hair strands to prevent uneven drying where middle strands remain humid while outer edges overheat.

Two parallel control levers on a personal care handle rotate independently to detect grip position, reducing user fatigue from manual switch activation.

Curved duct geometry accelerates airflow via the Coanda effect, reducing motor speed and noise while maintaining drying performance.

Segmenting fluid paths with a removable barrier isolates the primary stream, preventing motor overheating and boosting airflow efficiency.

Segmented apertures in the breathable sleeve create localized airflow zones that absorb moisture while preventing heat damage to curly hair.
