Colombia presents a problem associated with the access of low-income people who have disabilities to support products that conform to both their physical and socioeconomic needs. Standard low-cost Proaid M wheelchairs, designed from the union of parts manufactured in plywood and the use of commercial elements, are an object-based answer to this problem. The Proaid E model was developed for a 14year-old child with mixed cerebral palsy based on this design. A combination of the PSD Systemic Analysis Model-Built Environment and the User-centered Design approach was used for the development of the project. With the outcome of this project, we could positively impact the quality of life of a human being who did not have the minimum conditions necessary to meet his basic mobility and well-being needs.
