Steps Arrangement TRIZ Cases
- Folding Ladder Assembly with Linkage Mechanisms for Compact Retraction
Coordinated linkage assemblies move the ladder sections and railing into a nested configuration, reducing the machine profile while preventing collisions.
- Detachable Workpiece Support for Pickup Tailgate Step
A retractable tailgate step assembly integrates a detachable workpiece support bar and riser to create a stable surface for tools.
- Vehicle Step Apparatus Optical Control via OBD
Optical emitter and receiver bypass CAN bus security, enabling independent step control without modifying vehicle lines.
- Slidable Platform Assembly for Heavy-Duty Vehicle Engine Access
A slidable platform assembly attaches to vehicle frames, providing stable access points for maintenance tasks.
- Foldable Grille Mechanism for Heavy Vehicle Step Access
A foldable grille mechanism integrates a movable panel and actuator to form a secure step on heavy commercial vehicles.
- Vehicle Door Ramp Assembly for Accessibility
A vehicle door assembly integrates a pivotable ramp that slides with the door when stowed and deploys independently to provide ground-level access.
- Retractable Step With Pivoting Lower Segment For HGV Access
Segmented steps with a pivoting lower segment resolve the conflict between compact retraction and large deployment dimensions, reducing fall risks.
- Wireless Vehicle Step Control Bypassing CAN Bus Integration
A wireless vehicle step apparatus uses an emitter and receiver to drive the extending device independently.
- Mass Tuned Ladder Rung With Nestable Plates
Nestable ladder rungs with relief tabs eliminate weld fatigue while ensuring debris fall-through for safer off-highway work environments.
- Vehicle Step Assembly with V-Shaped Truss for Side Impact Energy Absorption
A vehicle step assembly integrates a V-shaped truss structure to distribute crash forces and enhance passenger ingress.
