Portable ramps, used generally by wheelchair users, offer temporary solution to increase accessibility and mobility. It is expected that these ramps should be compact and lightweight in terms of ease of handling and storage. Different types of portable ramps in the market, which can be used by wheelchair users, are generally made of aluminum and their compactness is convenient to be redesigned and developed in the matter of increasing compactness. In this context, the main objectives of the thesis are to determine the wheelchair users’ inclinations and design a product to achieve better compactness and lightness by comparison with similar products in the market. To this end, a case study addresses challenges of designing of a deployable structure to be used as temporary ramp. The design approach and its implementation are described briefly and example of parametric analyses are illustrated in this study. First, the geometrical design is performed considering several alternative forms. The link lengths are optimized for compact rolling. Then load bearing capacity of the assembly is analyzed analytically and also verified with finite-element analyses. Material selection is performed for the composite panels and the panel thickness is determined according to strength of materials calculations. Finally, prototypes are manufactured and tested according to standards. The final design is 15,1% more compact and has 20,25% less weight compared to the best rival product available in the market. Also the product was tested by some wheelchair users and their opinions about the product are asked. Positive feedbacks are taken.
