Preventing Unwanted Cargo Movement TRIZ Cases

Telescoping tube assembly adjusts track spacing to resolve instability caused by misaligned cargo control system tracks.

An automatic locking mechanism displaces and rotates an elongated shaft element to engage ISO container corners.

Segmenting the lashing fitting into a permanent housing and replaceable base eliminates deck cutting during maintenance.

A hanger member rests on cargo loads to position a deflated dunnage bag before inflation, resolving slumping issues that require manual adjustment.

Telescopic members in a T-shaped divider adjust to various cargo bed sizes, securing loose items and preventing damage during transport.

An arcuate hanger aligns external tie-down forces with the central axis, reducing undesired moments on leaf springs.

Continuous hook and loop strips anchor a freestanding L-shaped wall to the floor, preventing item movement during transit without sudden release forces.

Additional coupling means in corner castings share tensile stress with twistlocks, overcoming the 250 kN limit to allow heavier container stacks.

A lashing device uses a spring-loaded counter means to enable tightening rotation while resisting reverse rotation on the spindle.

Automated locking and stabilizing system secures cargo tub stacks in vessel cargoholds using integrated rails, wagons, and transfer locks.

Integrated anchor point simplifies mounting complexity while maintaining high load resistance.

Braces insert between cargo and load restraint strips to exert reactive outward pressure, preventing adhesive peeling under transport forces.

Integrated lever arm prevents attachment rotation and indicates safe thread engagement length.

Sliding head assembly with integrated elastic element absorbs structural deformation, maintaining secure restraint without extending beyond the cargo envelope.

Segmented body panels and adjustable straps prevent cargo sliding while maintaining low manufacturing complexity.

Segmented extendible tubular members fill voids to secure irregular cargo, reducing shifting damage while lowering installation labor costs.

Segmented injection molded braces prevent pallet shifting during transport by reducing device complexity through single-part construction.

A rod fixer uses a buckle handle to lock connecting rods firmly in place.

A motion compensation platform uses a three-point support system to stabilize tall offshore loads against vessel movements.

Calculates liquid natural periods to detect resonance with ship motion.

A modular utility vehicle uses pivotable couplings to attach detachable subsections for reconfigurable cargo handling.

A coil spring drives a reel to wind in fastening straps automatically, eliminating manual retraction effort and increasing operational efficiency.

Segmented chocking members with height-adjustable legs resolve the trade-off between transverse restraint reliability and system complexity.

Connecting adapter joins adjacent 20-foot containers to create a unified support base, enabling 40-foot stacking without modifying hatch cover structures.

A removable bulkhead structure resolves the contradiction between load support reliability and loading ease by enabling dynamic positioning.
