A curtain roller uses a magnetic stop part to prevent over-rotation during winding.

A slim double-skin window structure integrates a case-type glass fixing frame to guide an awning film within the hollow layer.

A variable light transmission panel uses a reflective coating stack to mask internal optical state changes.

Flexible electrophoretic film uses wavelength-selective optical composite to reject infrared radiation while transmitting visible light.

A pull cord extends from the headrail to allow users to operate motorized blinds from a comfortable standing position without reaching upward.

Linear linkage between two elastic motor units creates mutual opposition, fixing curtains at any height without pull cords.

A motor assembly output shaft features two distinct sockets to drive roller and non-roller blinds.

Laser ablation forms thin isolating lines between electrochromic zones to prevent short circuits and visual defects in multi-pane insulated glass units.

Staggered louver arrangement reflects direct sunlight while transmitting diffuse radiation, resolving tiled appearance defects.

Segmented adjustment units in the roll screen enable independent upper opening and lower light blocking, resolving the trade-off between visibility and privacy.

Plastic isolation rings prevent metal contact noise in screen drive compensation springs while maintaining compact radial space.

Asymmetric convex profiles disperse reflected light to minimize heat damage and glare from adjacent structures.

Single resilient arm guides and locks screening end pieces, eliminating complex separate guiding elements.

Solenoid valve actuates push mechanism to separate front cap from reeling engaging portion, enabling curtain fabric to lower by gravity.

Hidden wedge fasteners secure angled screen rollers without visible hardware, resolving the conflict between structural strength and aesthetic appearance.

Electric actuator releases torsion spring energy to retract sun protection curtains during power failure.

Segmented primary and secondary blades controlled by a torsion spring unlocking gear reduce window glare while maintaining deep interior illumination.
