Ladders TRIZ Cases

A pivotable latch engages an anchor rung to lock the top step in place.

Nested sleeves distribute shear loads through friction, preventing fastener breakdown and maintaining stile integrity without increasing material usage.

A multipurpose ladder uses a cable and pulley system to extend or retract sections remotely.

Triangular rubber-coated supports expand contact area on angled roofs to prevent ladder sliding.

An adjustable ladder knee rest distributes weight across padded arms to eliminate discomfort from static contact points.

Segmented ladder foot strip extends to reduce sinking risk while retracting for compact storage.

Adjustable telescopic legs and nested extension arms resolve stability contradictions on uneven surfaces while maintaining compact storage.

A mountable roller device attaches to ladder legs and steps to enable rolling movement.

Nested tubes and elastic plug pins enable stable height adjustment for ladder tool platforms while reducing logistical size.

A pivoting ladder shoe locks in place on slippery surfaces to provide secure footing.

A collapsible step ladder integrates handrails and a leaning support structure to assist users during climbing.

An inward-opening stepladder gate presses against a dedicated strike plate, separating support forces from uprights to reduce structural thickness.

A telescoping portable staircase with a hydraulic lift system adjusts length and angle, resolving ladder stability risks on moving drilling rigs.

A ladder stabilizer assembly uses a roof foot to provide friction against lateral sliding while a coupler engages the side rail rung.

A ladder holder uses upper and lower slots to mount a ladder at a fixed angle relative to a retaining wall.

Pawl locking mechanism secures cable ties over rung openings, eliminating wind noise without adding weight or weather-related failure risks.

H-shaped metallic clamping sockets encase parallel rope lengths into rigid members, eliminating manual tying failures and improving assembly reliability.

A ladder side step protection assembly uses a spacer to isolate the leg support covering portion from the overlapping rung surface.

A ladder platform device uses a base plate coupler and side fasteners to secure the structure to rungs and rails.

Pivotally disposed lateral supports engage a surface to inhibit tipping, resolving the contradiction between stability and structural complexity.
