Passenger Cycles TRIZ Cases
- Tricycle Vehicle Ball Joint Rear Assembly for Obstacle Adaptation
A tricycle rear assembly uses a ball joint to articulate the support frame, allowing independent wheel lifting over terrain.
- Railbike Reversible Clutch and Seat Mechanism
A railbike uses a reversible clutch and rotating seat to change travel direction without lifting the vehicle.
- Motorcycle Shock with Independent Air Chamber Control
Segmented air chambers with dedicated solenoid valves enable independent height and firmness adjustment while containing leak risks.
- Bicycle Rear Shock Linkage for Power Transfer
A rotating sub-frame isolates rear shock absorption from the rigid main triangle, preventing rider power loss during pedaling.
- Transport Bicycle Cabin Floor Element for Upright Access
A transport bicycle cabin floor element creates a closed surface with the roof to allow upright operator standing.
- Multi-track Bicycle with Articulated Rear Wheels
Articulated rear wheels and cardan shafts stabilize heavy loads on uneven surfaces, resolving stability trade-offs in urban cargo transport.
- Pivotable Front Frame for Multi-Track Vehicle Cornering
A pivotable front frame rotates the handlebar and saddle relative to fixed rear wheels, enabling natural rider lean during turns.
- Bicycle Head Tube Design for Lower Center of Gravity
Horizontal bearing placement in the head tube lowers the center of gravity, resolving stability issues caused by elevated cargo loads.
- Motorcycle Air Suspension with Dual-Acting Cylinder
A double-acting air cylinder system adjusts ride height and firmness via separate pressure regulators.
- Torsion Bar Suspension for Three-Wheeled Vehicle Tilting
Segmented torsion bars decouple rear wheel rotation to absorb road bumps while maintaining synchronized frame inclination.
