Freight Handling TRIZ Cases

Spring-biased retractable wheel assemblies keep aircraft cargo supports maneuverable while shifting heavy loads onto support sections to avoid floor damage.

A cable-driven trolley uses a retractable pawl to engage pallet cutouts, enabling rapid unloading with less manual handling and injury risk.

A mushroom-shaped locking guide with reinforcing insert secures aircraft cargo under high vertical and transverse loads while allowing flexible positioning.

A pivoting payload compartment lets a UAV switch between closed, top-access, and bottom-access states for flexible manual or automated delivery.

A self-propelled robot loads from landed or hovering aircraft to cut unloading idle time and support direct cargo delivery in disaster relief.

IMU and magnetometer feedback establish a stable cargo-hold reference frame, so operators can issue correct movement commands as controller orientation changes.

Distributed PDU controllers use direct mesh communication to move cargo with less centralized complexity and easier scaling across aircraft layouts.

Angled modular rails attached to aircraft seat tracks create a guided loading path that moves large equipment through entry doors with less damage risk.

Distributed PDU mesh control replaces centralized cargo panels to cut decision bottlenecks and scale across aircraft configurations.

Guide rails, rollers, and lateral rails adapt aircraft seat tracks to restrain cargo containers and keep weight aligned in passenger cabins.
