Sledge Wheels TRIZ Cases

A stabilizing mechanism with elongated nooks and rod channels adjusts a cart's configuration to manage its center of gravity.

Gear coupling links the main support and stabilizer arm, automatically deploying the wheel to resolve size versus stability trade-offs.

Elastic tongues deform during assembly to lock axles securely, reducing wear and preventing loosening in shopping cart chassis.

Relocating brakes from base casters to fork tine wheels improves stopping precision in tight spaces.

Mechanical ball screw assembly replaces complex hydraulic systems, enabling adjustable stabilizer stiffness without solenoid valves.

A chiminea cart features a curved handle arm to cradle the bulbous vessel body and rear wheels for transport.

A mobile cart features a height-adjustable arm and modular platform inserts for varied retail tasks.

A foot-operated braking and steering apparatus uses an action arm assembly to control heavy object movement.

A single fastener secures and positions dolly castors without welding.

Wheel recesses interlock stacked cart decks to reduce storage volume while maintaining transport stability.

A lowered bidirectional trolley uses a rotary rear system and retractable hook to facilitate effortless loading and unloading.

Segmenting the base, wheels, and restraints reduces shipping weight while maintaining structural stability for various drum types.
