Screens TRIZ Cases

A standing edge and supporting element stop lateral sliding in roll-up curtains, keeping serrated belts aligned and meshed.

A torsional spring brake and modular clutch keep the door operator usable in manual mode even when the electric motor is detached.

Lightweight frames, slotted connectors, and tabbed cover plates enable one person to assemble stable exhibit structures quickly without tools.

A threaded shaft and sliding carrier convert manual axial force into blind roller rotation, easing operation while removing chain hazards.

Two synchronized motors at opposite drum ends split torque, reduce torsional stress and voltage needs, and keep large roller curtains operable.

Detachable V-shaped joints and reinforcing frames let a sun shade mount securely on existing swing supports while staying easy to remove.

A hidden battery compartment with aligned access openings lets roller shade batteries be replaced at any shade position without tools or tracking loss.

Reflective side panels redirect wasted lateral sound toward the listener to cancel stereo crosstalk and avoid out-of-sync room reflections.

Folding legs, tubular bracing, and Velcro screen attachment make this portable wind screen stable in ordinary wind and easy to store.

Telescoping screen segments add patient privacy and airborne infection control on gurneys without blocking mobility during hospital transport.

Local vegetation and elastic straps create see-through 3D camouflage that avoids fabric silhouette effects and sudden movement that spooks game.

A funnel closure with a slitted disc and secondary seal keeps cut flowers hydrated during shipping and display while preventing leaks.

A motor-driven flexible sheet guides crosswinds toward the fan, improving air cooler efficiency with more reliable shield adjustment.

Different post heights let a changing table mount at either end while keeping safe rail spacing to prevent child entrapment.

A head-end privacy barrier cuts noise and light in mattress showrooms, helping users compare beds more comfortably and with fewer distractions.

A rotatable stator adjusts coil spring pre-winding in a roller screen, balancing easy opening with reliable retraction.

Integrated electromagnetic clutches, pull-chain disc, and brake enable fireproof rolling doors to open manually during power loss.

A U-shaped channel, adhesive bond, and local tensioning screws secure mesh screens without galvanic corrosion or protruding fasteners.

Magnetic screen edges release under strong wind to cut drag, keep the traffic barrier upright, and block incident views that trigger gawking.

A rigid backing with an adhered flexible image substrate delivers canvas-like appearance at lower cost while resisting warping and simplifying assembly.

A rotating, sliding bracket lets one roller shade mount handle wall or ceiling installation while correcting horizontal and vertical misalignment.

Segmented left and right supports with hooked decoration and cover boards prevent wall detachment and create a cleaner roller curtain installation.

A roller-driven lift sheet replaces hazardous cords in architectural covers, enabling child-safe operation of heavy shades with guided folding.

Tabs engaging motor crown grooves secure the shade motor in the tube while allowing removal without fully unwinding the fabric.

An automatic clutch lets motorized drapery switch between powered movement and manual pulling without extra coupling steps.

A fiberglass core with closed-cell foam lets the curtain tension bar bend on impact and recover, avoiding rod damage and closure downtime.

Stretch-open slits in a flexible curtain panel vary light transmission with minimal movement, reducing energy use and facade space demands.

A retractable roller shade closes rack gaps of varying sizes, letting filler panels adapt as equipment is added or removed.

Winged splines and a cut-to-length telescoping extension let roller shades fit different window widths without adding complex mechanisms.

A support post storage space houses the shutter electrical unit to avoid projection, reduce damage risk, and simplify maintenance.

A self-contained roller shade uses a spring and pulley to bias fabric tension within a free-standing frame.

A spring-biased pulley system extracts tension from the motor, reducing noise and complexity while preventing fabric sagging.

A rotating end cap pivots an extension to compress the roller length within a vehicle shade assembly.

Merges the antenna and receiver inside the tube to reduce cabling complexity while maintaining reliable signal transmission.

A spool-mounted barrier system seals elevator openings using a drive assembly and sensor control.

Pivot mechanisms allow the bottom bar to rotate under windloads, limiting deflection to prevent curtain damage and seal failure.

Deforming a serrated belt adjusts tooth positions during rolling, resolving imperfect engagement caused by curvature and thickness variations.

Segmented stretching bars and self-service connectors resolve trade-offs between tightness, time, and storage volume.

Automated spool mechanisms deploy fire-resistant barriers to block smoke migration in elevator shafts, resolving rapid vapor spread through lobbies.
