Portable Bridge TRIZ Cases

A hook, protrusion, and channel layout creates a modular ramp that fits different structures while keeping attachment stable and angle-adjustable.

A hook-and-channel ramp assembly adapts to lips on buildings, containers, and vehicles while enabling secure mounting and variable ramp angles.

A hook-and-channel modular ramp attaches securely to building or vehicle lips while adapting ramp angle to uneven terrain.

A movable bridge section and beam support let tunnel crews span gaps from one side, avoiding heavy lifting and reducing installation time.

Multiple hinged ramp sections rotate beyond 180° to adapt vehicle passage across bumps, slope changes, and steps.

Articulated bridge segments fold to adjust the center of gravity, eliminating additional support devices during vehicle transport.

A modular access structure uses deformable lower and upper support structures to transition between extended and collapsed configurations for transport.

Hydraulic wheel assembly with tension springs erects automatically, eliminating manual fork truck connection steps.

Unmanned laying vehicle uses laser scanning to simulate obstacle approach, eliminating soldier exposure to enemy fire during deployment.

Segmented ribbed arch with lateral stabilizers distributes road loads to prevent pipeline folding and vibration damage.

Interchangeable ground contact elements with optimized surface structures improve stability on diverse substrates, eliminating manual anchoring.

Pre-formed bridge sections connect via stringers while a guided trolley carries loads across the span, eliminating heavy assembly equipment.

Overlapping bridge section protects composite materials from damage during maintenance by shifting loads away from the manhole edge.

A hitch-mounted loading ramp transitions between transport and trailer modes using spring-loaded hinges.

A vehicle mount with engagement fingers secures removable ramps for curb traversal.

A mobile bridge system uses articulated vertical connections and distinct bearing mechanisms to maintain static definiteness across long spans.

Segmented plane members pivot on hinges while stiff wires tauten via handles to resolve weight versus stability trade-offs.

A collapsible modular beam structure uses a dead center mechanism at hinge connections to lock side elements into rigid configurations.

Automated leveling systems correct sagging at hinged joints on uneven surfaces, maintaining structural stability under heavy loads.

Dynamic gangplanks bridge height gaps between terminals and low doorsill airplanes, shielding passengers from weather exposure.

Hingedly connected modular girders self-support heavy loads across levees without transferring weight to the obstruction.

Cables and pulleys allow a single worker to articulate an ultralight passenger bridge, resolving wind-load stability challenges.

Dynamic mobile terminal gates reconfigure gate spacing to reduce surface congestion and fuel consumption.

Segmented fiber composite crossbeams reduce component weight while maintaining structural stability for faster assembly.

Pivoting the second component into a locking position secures the fastening element, eliminating loose parts and reducing device complexity.

Segmented hollow cylinders with L-shaped stress members connect via pins and sockets to support heavy loads without precise piling alignment.

Integrating tongue and groove joints into the carrier eliminates loose fasteners, preventing lateral displacement while simplifying assembly.

Segmented ramp units link via self-locking connectors to adjust length for varying curb heights without tools.

Segmented ramp assemblies adjust slope angles via dynamic control to accommodate varying curb heights while maintaining safe passenger accessibility.
