Design of A Stair Wheeler for Wheeled Luggage

The development of the Concept Design presented in this report was modeled and simulated by using CAD tools.¿ Prototype and testing are made for concept-1 under load conditions and normal staircases (30-25cm width and 15-12cm height).¿ With multiple attempts of prototyping and testing.¿ The luggage is successful moving upstairs with less effort.¿ While luggage is getting downstairs successfully, but it needs further improvement in suspension. ¿ Twisting of luggage occurs when it is dragged downstairs due to uneven load distribution.
