Ramps TRIZ Cases

Braked wheel tracks and a pivoting ramp let wheelchair users descend stairs safely when elevators and fixed ramps are unusable.

An embedded grit surface bonded with polyol-isocyanate adhesive supports durable slip resistance and easier wheelchair ramp installation.

An adjustable drive assembly moves a ramp panel to resolve space consumption conflicts while maintaining architectural aesthetics.

Deployable ramp uses a pivoting foot lever to raise its upper end, enabling smooth vehicle traversal over obstacles.

Movable stair parts rotate automatically via sensors to create a ramp, resolving space constraints while maintaining safe access for wheelchair users.

Vertical translation of the plate and pivoting flap deploy a ramp without requiring horizontal sidewalk clearance.

A linear actuator drives a carriage to pivot arms, raising a plate into an access ramp.

Modular extruded aluminum components reduce assembly complexity by combining structural support, decking attachment, and spacing functions.

Elastically yielding brush hairs on a ramp engage bicycle wheels via interference fit to reduce physical effort during speed control.

A foldable ramp system provides a safe access pathway for mounting riding animals.

Collapsible handrail assemblies fold inwardly to reduce storage volume, resolving bulkiness issues in modular ramp systems.

Segmented plastic ramp units reduce handling weight and noise generation.
