Hand Carts With Multiple Axes TRIZ Cases

A multi-purpose beach cart features a hinged frame for compact folding and modular storage components.

A roll container base plate uses a pivot axis holding mechanism to maintain an upright position without manual intervention.

Laterally offset load rollers pivot on an arcuate carrier, reducing longitudinal space and enabling lift trucks to overcome larger obstacles.

Interlocking buckle parts engage limiting features in a sleeve to prevent detachment while simplifying installation.

A foldable camping cart frame uses a three-segment linkage to synchronize folding actions across independent structural assemblies.

A cart handle assembly uses a Hall sensor and permanent magnet to detect applied force direction for targeted power assistance.

A pivotable drum and locking pin secure a wagon handle, enabling easy angle adjustment via a release pedal.

Merging separate X-assemblies into a single cross structure eliminates staggered mounting, reducing wagon volume while maintaining structural strength.

Adapter brackets stabilize fragile cream cases on trolleys, reducing packaging waste and transport trips.

Tubular golf club racks with sockets and clips organize clubs on carts, preventing damage from random movement during transport.

A shopping cart handle with rotatable grips secures in vertical or horizontal positions via a cam and spring mechanism.

A nestable shopping cart tray uses a tapered front and perimeter wire to enable compact vertical stacking.

Asymmetrical base design and adjustable shelf heights enable horizontal nesting of stacked carts while maintaining structural stability.

An S-shaped clip holder mounts to a shopping cart seat back, maintaining device visibility and preventing damage through segmented geometry.

A rotatable push handle pivots on a transverse axis to reduce transport height.
