Sledges TRIZ Cases

A frame with a vertically movable wheel assembly and catch mechanism supports heavy panels for transport.

Lever-driven remote actuation rotates locking pins to secure cargo without personnel traversing the hazardous gap between the dolly and aircraft loader.

A stackable transport trolley uses a snap clasp and groove mechanism to secure the flap back part onto an axle for easy assembly.

Telescoping handle assembly widens wheel track width to resolve stability versus compactness trade-offs in portable medical devices.

Hinged cover locks shopping cart basket top and sides using a latch mechanism, preventing unauthorized access to stored items.

A handheld abrasive tool sharpens snowmobile carbide wear rails using a drill attachment.

Adjustable mobile cart uses conductive casters and mats to maintain continuous electrostatic ground connection during transport.

A spring-biased engagement member rotates to secure a shopping cart frame within a housing.

A multi-function cart uses convertible shells and interchangeable tubes to store emergency supplies.

Dual-spring segmentation allows independent bolt operation, reducing the force required to align pins with locating holes in transport semi-trailers.

A modular shopping cart frame uses a one-piece plastic basket to simplify assembly and reduce manufacturing costs.

Pivotable support legs on a transport frame prevent sagging of flat elements while enabling compact storage for return logistics.

An adjustable tow bar with a locking mechanism transitions the dolly between manual and vehicular modes, resolving the need for separate devices.

Cross-linked air volumes redistribute spring forces, reducing rider effort for deeper snow turns while maintaining hard-pack handling.

Segmented modules and dynamic panels adapt to varying bin sizes, resolving the contradiction between capacity and stability.
