Portable Bridge TRIZ Cases
- Modular Ramp Hook-and-Channel Assembly for Variable Access Angles
A hook, protrusion, and channel layout creates a modular ramp that fits different structures while keeping attachment stable and angle-adjustable.
- Modular Ramp Assembly for Adjustable Lip-Mounted Access
A hook-and-channel ramp assembly adapts to lips on buildings, containers, and vehicles while enabling secure mounting and variable ramp angles.
- Modular Ramp Attachment Structure for Variable-Angle Access
A hook-and-channel modular ramp attaches securely to building or vehicle lips while adapting ramp angle to uneven terrain.
- Crawler Bridge Structure for Single-Side Gap Crossing
A movable bridge section and beam support let tunnel crews span gaps from one side, avoiding heavy lifting and reducing installation time.
- Hinged Vehicle Ramps for Bumps, Slopes, and Steps
Multiple hinged ramp sections rotate beyond 180° to adapt vehicle passage across bumps, slope changes, and steps.
- Foldable Bridge Center of Gravity Adjustment via Articulated Segments
Articulated bridge segments fold to adjust the center of gravity, eliminating additional support devices during vehicle transport.
- Modular Access Structure with Deformable Supports
A modular access structure uses deformable lower and upper support structures to transition between extended and collapsed configurations for transport.
- Mobile Loading Dock Wheel Assembly Automatic Deployment
Hydraulic wheel assembly with tension springs erects automatically, eliminating manual fork truck connection steps.
- Unmanned Bridge Laying Vehicle with Laser Scanning
Unmanned laying vehicle uses laser scanning to simulate obstacle approach, eliminating soldier exposure to enemy fire during deployment.
- Pipeline Crossing Bridge Arch Structure
Segmented ribbed arch with lateral stabilizers distributes road loads to prevent pipeline folding and vibration damage.
- Profiled Ground Contact Element for Deployable Bridge Stability
Interchangeable ground contact elements with optimized surface structures improve stability on diverse substrates, eliminating manual anchoring.
- Segmented Bridge Deck Launching via Guided Trolley
Pre-formed bridge sections connect via stringers while a guided trolley carries loads across the span, eliminating heavy assembly equipment.
- Aircraft Manhole Access Bridge with Overlapping Section
Overlapping bridge section protects composite materials from damage during maintenance by shifting loads away from the manhole edge.
- Hitch-Mounted Loading Ramp for Motorcycles
A hitch-mounted loading ramp transitions between transport and trailer modes using spring-loaded hinges.
