Light Protection Screens TRIZ Cases

A variable transparency screen stretches via traction cords to adjust light permeability without complex mechanisms.

A window covering leveler adjusts vertical position via a rotating threaded member and ramped guillotine mechanism.

A retractable curtain cord adjusting device uses a detachable stopper within a mounting groove to wind and fix the cord length.

Guard plates prevent constant force springs from reeling off and reduce operational noise while maintaining adjustable elastic force stability.

Segmented thin glass sheets enable flexible dye-doped liquid crystal windows without compromising optical quality or structural strength.

A cord-winding device uses a pawl and ratchet mechanism to control brake rotation, maintaining bottom rail balance without direct manual operation.

A string holder uses a removable insert with multiple sockets to adjust fabric roller shade tension.

Double bus bars optimize voltage distribution in electrochromic stacks, resolving inconsistent tint levels and slow switching speeds.

Nesting the awning roller and cable tensioning means inside the actuator enclosure resolves interference issues during loft window installation.

Sun angle sensors transmit data to a motor controller, which rotates the roller tube to limit sunlight penetration and reduce UV exposure.

An exterior ladder system with connection rings secures a window shade, preventing cord entanglement and stiff operation inside the compression tube.

Segmenting inter-layer spaces with distinct switchable components resolves the trade-off between dynamic light control versatility and structural complexity.

Segmented spacer frames manage pressure differentials in large cavities, preventing seal failure and glass breakage during temperature fluctuations.

A brake spring tang support minimizes rotational drag to extend battery life in motorized window treatments.

A spindle mechanism winds lift cords to adjust bottom rail length in window coverings.

A thermotropic composition uses salt nanoparticles in a polymer host to create a scattering layer that reflects incident light based on temperature changes.

Individual slat drives resolve the trade-off between adaptability and device complexity.

A learning module analyzes current and voltage data from tintable windows to identify malfunction patterns.

Elongated frame members form vapor egress channels to resolve bonding failures from trapped moisture while ensuring uniform adhesive distribution.

Variable light transmission panels connect to the building's main power supply, eliminating battery replacement needs and technician requirements.

Reflective upper faces on orientable slats redirect sunlight inwardly while extended opaque strips preserve privacy without complex cord routing.

Sealed ball bearings in the idle end assembly reduce wear, while a spring connected to a metal strap dissipates static electricity.
