"OPTIMIZATION OF MOBILE SYSTEMS FOR DISABLED PEOPLES USING 3D PRINTING "

"Product innovation involves an understanding of technology through the introduction of a new product or a product that has significantly improved characteristics with the purpose of upgrading or even changing, in this case, the mobility landscape. Following the analysis of the literature in the field of methodologies for the development of an existing product or the design of a new product, the stages and activities that will be completed in order to develop an autonomous mobile system for transporting people with disabilities and transforming a manual wheelchair in an electrically operated wheelchair were established. On a basic manual wheelchair, a system will be attached to ensure overcoming the obstacles and to guarantee the ability to negociate effectively. The components, along with the control system and source energy, were mounted and tested to determine the behavior of the developed system. Various components (external and internal support, toothed crown, pinion, mobile element) were 3D printed in order to explore improving of frame attachment, the rotational movement transmission of the motor and the technical solutions for attaching the crown to the wheel. Key words: product design, wheelchair, simulation, 3D printing, optimization, mobile system. "
